Drilling jig: application. We make our own jig for drilling holes Universal jig for drilling holes
A drilling jig is an indispensable attribute in large-scale production, no matter what kind. Where there is a lot of drilling, it is really necessary, especially when production is serial or mass.
With the help of a conductor, production is greatly accelerated and the worker's work is made easier.
A drilling jig, as a rule, is a bar (plate) with holes and bushings (sleeves). Using a jig it is much easier, for example, to drill pipes.
As for furniture production, they are also used here, although relatively recently.
With the help of such equipment, the manufacturer is relieved of the following problems:
- Marking.
- Punching (point depressions in the material for a drill).
- Drilling while maintaining perpendicularity.
The latter is especially difficult to achieve, since it requires serious skills acquired only over the years.
Some operations, for example, drilling for dowels (short wooden rods designed for hidden joining of parts), require very precise markings, and no less accurate drilling at an angle of 90°.
With such a device as a conductor, these tasks are solved easily and simply.
Types: choose the one you need
Invoices. They do not require fixation before being used for their intended purpose. Structurally simple, mobile, but they need to be held with a hand free from the drill, since often the equipment is not secured in a special device, which is not very convenient. Considering the simplicity of the design, making it yourself is quite simple. Used when drilling chipboard and MDF.
Jigs for drilling holes at an angle. The design is easy to imagine, since the name speaks for itself. Such equipment can also be an overhead one. In production quality furniture There is also drilling at an angle, which is not the most simple operation V production process- this requires skill. Although in this case the required angle is sometimes violated, as a result the assembly will not be of such high quality and will suffer appearance furniture, especially if it is not made of chipboard, but of wood - here you won’t be able to fill in an unsightly drill. The equipment desired design completely eliminates unnecessary problems.
Rotary conductors. They have folding brackets, and this allows drilling on two adjacent planes.
Sliding gearboxes. With their help, you can drill several holes without reinstallation. To work with such equipment, the necessary skills are still required.
Device for drilling holes for dowels and confirmats
Despite the fact that today in the furniture industry there are many new fittings, the good old dowel is still used today. This is explained by the fact that the connections are not visible through this piece of fittings, and this is especially valuable in the production of furniture made from natural wood.
As already mentioned, drilling for dowels creates many problems for furniture makers, especially those who are not sufficiently qualified.
In order for the furniture planes to be perfectly aligned, precise markings are necessary, and this equipment allows you to speed up the work and bring the quality to the desired level.
Working with confirmats - special furniture screws - although less troublesome, also requires certain skills. And considering how many holes need to be marked and drilled before screwing the confirmation into one piece of furniture, such a device will significantly speed up the work, and its quality too.
The simplest devices
- The conductor is two-slider. It allows you to drill holes in two adjacent (mating) parts. The device is constructed of two rulers, which serve as guides and are connected to a mounting strip. The holes made in it make it possible to install a bar on the parts different widths. Housings moved along rulers (replaceable) have a set of guide bushings, where the distances between them are different. The conductor is fixed by means of a connecting strip, with opposite side There is also a travel limiter, pressed by a thumbscrew.
- The conductor is multi-position. Fastened with clamps. The design allows you to produce vertical drilling. It is made of thick-walled aluminum angle. Since the device is of considerable length, it is equipped intermediate fastening in the center of the structure. The thick wall of the angle was used very successfully, which cannot be overestimated at the moment of placing the device on the surface of the part and when reinstalling the jig to 90°. The selection of the distance between the bushings is carried out according to the most common values provided for installing dowels or confirmations.
Procedure for working with a conductor:
- The device is fixed on the workpiece.
- The sleeve is inserted into the hole.
- Drill through the sleeve.
DIY furniture jig: drawings with dimensions to help
The principle of this equipment:
- Angular housing. It is superimposed on the planes of the parts, which will then be connected to each other.
- Guide bushings. The drill will go through them.
- Clamping devices. They fix the conductor and are made from the end part.
Designing your own jig should be based on the fact that with the help of this equipment it is possible to do most of the work performed related to various types of fasteners.
Important! If you need a universal assistant - this applies to professional furniture makers, then it would be better to purchase industrial equipment that is made more accurately and with high quality. It is this kind of device that will be preferable and will quickly pay for itself, especially if you also take into account the fact that this device often comes with many different templates, stops and other little things that are also necessary in the work. They are much cheaper than buying at retail.
And yet this device, if necessary, can be made with your own hands.
Such equipment may not be needed very often in a given production, let alone home handyman- especially. So for many users it will be much more profitable to do it themselves.
If the design remains relevant, then you need to prepare materials for manufacturing self-made conductor for drilling for confirmation:
- Corner. Your choice should be made on the unequal type of this rental - its possibilities are wider. The corner shelf must be chosen with the greatest thickness, which can reach up to 8 mm. This is quite justified, since then guide bushings can be inserted, O.D. which reaches 6 mm. Based on this, you can use drills from 3.5 to 4 mm. Even if that diameter is not enough, then the material is drilled out with a large drill, without using any other devices.
- Guide bushings. Here pipes from stainless steel, which are selected primarily according to internal diameter. Example: a 6x1.5 pipe is suitable for a drill no larger than 2.7 in diameter. Explanation: internal hole it will be 3 mm, and a small gap along the entire internal diameter is taken into account due to thermal expansion material. The length of the sleeve is the depth of the hole in the corner, multiplied by two or more. The fit of the bushings is either transitional, or with an interference fit, or according to the shaft system. The latter is the most appropriate.
Instead of pipes, of course, you can use ready-made bushings used in wire drawing machines - these are available, for example, in mechanical engineering. Such parts (even used ones) come in handy: they are made of alloy steel and have an almost unlimited service life.
Choosing a mounting method
Options:
- Fixation using self-tapping screws. They are screwed into the part, which prevents the device from moving due to friction. This is convenient because these marks will be needed for subsequent drilling of other holes.
- Spring stop. It will securely fix the jig to the part. For such a stop, a flat spring with an appropriate clamping force is suitable.
- External clamps. Rubber pads must be placed under them. Corrugated rubber is ideal as a material. This, of course, slightly increases the weight of the equipment, and the elasticity of the pads can negatively affect the perpendicularity of the bushings. To prevent this from happening, the drill is inserted into the sleeve to mark the hole, and only then the clamps are clamped.
For drilling pipes and cylindrical parts
IN modern furniture Not only chipboard, fibreboard, MDF and wood are used. As additional elements may be applied steel pipes various diameters. Covered with chrome or stainless steel, they perfectly complement the overall furniture ensemble.
It is very difficult to drill into a spherical surface - the drill tends to slide to the side. And it’s not so easy to mark when there are a lot of holes and they are located in several rows.
In order to ensure that the pipe does not turn out to be the notorious colander, but the correct part with precisely made holes, you will need a jig - this perfect solution in the current situation.
There are steel conductors made in the form of an adjustable clamp. This design feature allows pipes to be clamped into them different diameters and drill holes in them with high precision.
Not being able to make such a device, you can use waste materials, making an even simpler device using a block and a strip of plywood. Thus, a block cut diagonally lengthwise into circular saw, can be nailed or screwed with screws at an angle of 90° to the plywood. The resulting device is placed on top of the pipe, and a strip of plywood, resting against a table or workbench, prevents the specified angle from being violated. Holes of the required diameter pre-drilled in the block are placed taking into account the required distances between future holes, which will allow you to quickly and accurately drill the pipe exactly according to the drawings.
DIY furniture conductors and templates
How conductors are made is now clear, as is their necessity for furniture production.
Not only conductors, but also templates are needed in furniture production. The simplest template will sometimes save a lot of time and allow drilling to be no less accurate than a jig.
For example, the simplest metal prefabricated invoice template, consisting of two sheet blanks measuring 130×70 mm and a steel square with a cross-section of 20 mm. They are connected to each other by screws at the top of the structure - this is how they are attached to the square. The square is drilled for the bushings, where the latter are pressed. Such a device for drilling holes in the end of a part made of chipboard will make it possible to drill without thinking about marking and perpendicular drilling. And the price of this equipment is below any idea of savings.
Instead of metal, you can and should use those materials that are inexpensive and easy to process.
Materials:
- Plywood.
- Textolite or fiberglass - preferably thick.
- Hardwood.
- Hardboard or its equivalent.
It must be borne in mind that these materials are short-lived, and so that the devices do not have to be made every day, it is quite reasonable to press metal tubes into them.
In conclusion, it is worth summing up what has been said. Making a conductor or template yourself or buying it in a store is a matter for everyone individually. If a home craftsman needs to make some furniture in a single copy and there is material for a conductor, as well as the possibility of making it, you can use this. It is possible that such equipment will never be useful to the master again.
But if even a small furniture workshop is engaged in the production of serial furniture, and enough people work in it, it is probably easier to purchase something ready-made, especially since these irreplaceable helpers They will need several masters.
In the latter case, it makes sense to purchase more expensive, accurate and wear-resistant jigs instead of making homemade ones, which are less accurate and durable.
Good luck in your work!
Sometimes at home you need to make holes in blanks made of wood, metal, chipboard or other material.
Rotary
The device body is equipped with bushings that adjust the rotation axes in horizontal, vertical and inclined planes. These models of jigs are designed for drilling cylindrical products.
Sliding
The name speaks for itself, the jig is not attached in any way, it is simply placed where the hole needs to be made.
Tiltable
Capable of making holes in several planes.
Stationary
They do not have rotating elements and are capable of moving the part and processing workpieces of the same type.
Universal
These conductors have a function such as readjustment. This allows small businesses to quickly and conveniently switch to the production of a new product.
Description of conductors
Let's start with the concept of conductor is a so-called template, the use of which allows for comfortable and ultra-precise drilling.
Moreover, you can drill either perpendicular to the surface or at any angle. If you use a conductor, then you do not need any special qualifications to do complex calculations, make markings where the holes will be, which saves a lot of time.
Areas of application
As we can see, due to the versatility and simplicity of their design, conductors are widely used in different areas activities.
Mechanical engineering
In the mechanical engineering industry, they are used for drilling holes in various workpieces made from common materials. Conductors are used that repeat the drawing with exact observance of all dimensions. Also used when drilling holes is required mixed type.
Furniture production
The most widespread use of conductors is in furniture production. Furniture conductors are used for installing fittings, assembling furniture and many other technological processes.
At the same time, furniture assembly is neat, precise and fast. A large amount of furniture contains dowels, which must be installed very precisely and there is no need for a conductor.
The most common jig for dowels is doweling. They mainly use overhead conductors made of lightweight materials.
Construction
Another area in which jigs are widely used for drilling holes is construction. They are used to drill technological holes in building structures, For example, .
Main advantages of use
You can buy a conductor or make it yourself.
But before choosing a model, you should decide for what tasks it will be used and, based on all this data, you should choose the type and design of the tool.
So why should you use jigs for drilling holes?:
- Intuitive use that does not require professional skills.
- Low price of the device, as well as the possibility of self-production.
- Saves a lot of time.
- There is no need to mark the surface to be treated using.
- Maintain precision when drilling.
A jig for drilling holes is an integral part not only of production, but it will also be useful in home life.
How to make a conductor with your own hands
Since there are many types of conductors, we will consider original design and analogue respectively. And so let's begin.
Jig for perpendicular drilling
Its main purpose is to make holes in thick workpieces at an angle of 90. In essence, it is a set of bushings combined in one body. Usually these are overhead conductors, which are widely used in furniture assembly.
Just place the device on the surface and you can start drilling right away, without punching. There is one drawback: the device should be held tightly, especially at the beginning of work. Because vibration can cause the device to shift.
This type of conductors can be made with your own hands.
- You can use it as a base wooden block, a piece of PCB, reinforcement with square section 10x10 mm.
- We treat the surface well, clean it and begin marking.
- Please note that the center of the holes should be 8 mm. from the edge of the workpiece. This is due to the fact that 8 mm. this is half the thickness of the sheet.
- According to standards, there should be exactly 32 mm between the centers of the holes.
- After that, we make holes with a diameter of 5 mm in these centers.
A homemade conductor can be used, but for more convenient use a stop should be constructed; for this, metal 23-25 mm wide is used. and 1 mm thick, after which the sheet is bent at an angle of 90 and attached to the conductor. Also, bushings of different diameters can be inserted into the base of the conductor.
Conductor for pipes and cylindrical blanks
Everyone knows that making a hole in a sloping surface is problematic; the end of the drill constantly jumps off. This type of conductors is fixed in a given position and allows you to work with high precision.
This type of conductors can be made quickly and independently.
- To do this, we need a block of hard wood, loosened diagonally. And we attach a piece of plywood to the edge of the block using self-tapping screws.
- Then we make holes of the required diameter in the wooden block.
That's it, the conductor is ready for work. To make the holes less likely to break, they can be reinforced with metal sleeves, which are made from round pipes of different diameters.
Jig for drilling holes at an angle
This type of drilling is rarely used.
It should be noted here that in metal products this type of hole is made only with a milling cutter. And as for wooden products, then there are ready-made solutions in the form of kits.
It’s easy to use these jigs; we press the workpiece tightly to the base, set the specified height, and as a result we get smooth and beautiful oblique holes at an angle. Yes, if we don’t need a through hole, then don’t forget to put a stop ring on the drill itself.
On your own this type The devices are difficult and problematic to manufacture. There is enough simple ways and options, but they are not accurate. So, for example, a drill is placed on a prepared inclined surface and our workpiece is drilled at the resulting angle, as we understand, the accuracy suffers greatly.
Jig for drilling holes for dowels
Their main purpose is to maintain the alignment of the holes, into which dowels will subsequently be installed. That is, when you apply the jig to both sides of the product, you get a perfect joint.
As you understand, this type of conductors can be made independently. If you have a flow of workpieces with the same geometry, it will be convenient for you to use an overlay template. It is advisable to use hardboard or other material as a template. transparent material(plastic).
We mark and drill holes. It is advisable to drive brass or copper tubes into the holes so that the drill does not break the calibration hole.
Universal device
When you use blanks various forms and sizes, then you will need universal device. The most interesting thing is that this device can be made from scrap materials.
- For this we need plywood about 15 mm thick.
- We make three identical blanks.
- We make holes along the edges into which dowels are installed as legs.
- We make one hole in the middle, which we reinforce with a metal tube.
- Let's make three metal strips with symmetrically located holes, they will serve as a shoulder. These shoulders are responsible for the linearity of the holes of the future conductor.
- We make cuts in the plywood blanks and install metal shoulders, securing everything. Our universal self-centering jig is ready.
Conclusion
Any universal jig for drilling holes is made to save time and money. Whether you make it yourself or buy it ready-made in a store is up to you to decide.
Today, construction uses devices that facilitate the processing of materials. For example, a jig for drilling holes is one of those devices that allows you to carry out work without the use of any marking tools.
What is the product?
The presented device allows you to do the job as accurately as possible. It is a special box that provides required parameters holes. That is, you can easily adjust the angle of entry of the drill into the material being processed. Moreover, if there are several parts, then drilled holes will match.
It must be said that such devices can be purchased at any hardware store. Their cost ranges from 1000-2500 rubles. However, you can make a jig for drilling holes yourself. This is especially necessary if the work requires special parameters.
Advantages of the device
The drilling jig has the following advantages:
Reasonable cost and the possibility of making it yourself.
There is no need to use a ruler, pencil or other means to mark the surface to be treated.
Reducing the labor intensity of the procedure.
Very simple use of the product, intuitive even for an amateur.
As you can see, the hole drilling jig is very useful device For household or for a small business.
Areas of application of the product
In principle, such a device can be used almost anywhere. For example, it can most often be found in the process of making furniture. This kind of work requires precise parameters. Using measuring instruments takes a lot of time. This entails additional expenses, which can be disastrous for a small business.
The conductor is also a very important device in mechanical engineering. Here the equipment of the device plays a huge role. It must be as accurate as possible. As you can see, the presented device is quite common and useful. It makes your work much easier.
Device design
The jig for drilling holes, a drawing of which you can see in the article, may have different designs. It all depends on the purpose for which the device will be used. For example, if you purchased a device in the form of a small strip or corner with holes drilled in one line, then with its help you can make holes in one row at right angles.
If you do not need such a design, but need more difficult option with holes that are not on the same axis, then you will have to make the device yourself. You can find out how to do this below. However, first you need to understand the varieties of products presented. As you can see, the conductor for perpendicular drilling The holes have a not too complex structure that even an inexperienced craftsman can figure out.
Classification of devices
So, we can distinguish the following types of devices:
Stationary. They differ in that they do not have rotating elements capable of moving the workpiece. That is, those products that are drilled are of the same type.
Invoices. Their feature is considered to be simplicity of design and low cost. To operate such a device you simply need to put it on the part that will be processed. It must be secured with a washer and nut.
Tiltable. They are capable of drilling several holes in one part. However, they may have different angle in relation to each other.
Rotary. In this case, the location of the conductor bushing is determined by the dividing disk.
Rocky. Such products are most often installed on professional drilling machines. They are especially in demand in the mechanical engineering industry.
How to choose the right device?
In order for the hole drilling jig, the photo of which is presented in this article, to successfully cope with the tasks assigned to it, you need to purchase correct device. When choosing and purchasing, try to follow these recommendations:
1. Type and purpose of the device. This parameter is the most important. If you choose the wrong device or its accessories, it will be useless to you and your money will be wasted.
2. Cost of the device. This parameter is also important. You should not give preference to the cheapest products that may come apart the first time you use them. Buy durable metal devices.
3. Manufacturer's warranty. Do not purchase an item from basement. There you are not insured against counterfeits or defective goods. It is better to contact an official certified point of sale, where you can exchange the product under warranty if it does not suit you or turns out to be non-functional.
4. Additional features. Today, a jig for drilling pocket holes can be equipped with special devices, which help eliminate dust during operation, or other devices.
5. Manufacturer. Here everything depends on your taste and the reputation of the manufacturer. Now the most popular is the Wolfcraft hole drilling jig.
Features of self-production
This is not at all difficult to do. First you need to select required material. A channel or corner is best suited for this purpose. Naturally, before processing the workpiece, it is necessary to make a template according to which the holes will be drilled. The diagram can be drawn on a regular sheet of paper.
Next, you need to make markings on the workpiece itself. After this, it must be clamped in a vice or with clamps, and only then drilling can begin. Please note that doing this strictly perpendicularly is quite difficult. The fact is that you can manually make a hole with a certain deviation. Moreover, the thicker the workpiece you choose, the more difficult it will be to work with.
Next you just need to drill holes at the marked locations. When doing this, take into account the diameter of the drill. It must exactly match the size of future holes on the material being processed. It is best to use for this purpose drilling machine. It is this that will allow you to achieve the desired angle of 90 degrees. If there is no drilling machine, then the drill must be fixed so that it does not deviate. To do this, you can use all kinds of stands.
Features of the device
The KWB hole drilling jig, like any other device of the presented type, must be used correctly. Only in this case will you be able to achieve a positive result. So, try to comply with these conditions:
During operation, all parts, as well as the device itself, must be as clean as possible from dust or other contaminants.
Try to choose exactly the drill that will suit you in diameter.
Please note that when installing the jig, it must lie flat against the plane of the table. Naturally, at this stage you should also set the drilling depth.
When selecting the rotation speed of the drill, it is necessary to check that the drill is installed correctly for runout.
The workpiece must be very firmly fixed to the jig.
The drill must be brought to the product through the guide sleeve and drilling must begin.
Please note that you should not press too hard on the tool while working. Otherwise, the drill may simply break or lose its sharpness.
After completing the work, you must carefully remove the tool from the part and unscrew the jig.
During all manipulations, try to comply with safety rules as much as possible. For example, wear protective clothing, gloves and goggles. If you feel that the tool is starting to malfunction, stop working immediately. Otherwise, you risk injury.
That's all the features of using the conductor. Good luck!
A jig for drilling holes is a device used in mechanical engineering to simplify the process of processing a part. In essence, it is a template that serves to guide or position the workpiece. Can be used on various equipment, for example, such as a diamond drilling installation.
In mechanical engineering, jigs are fairly precise devices (up to 0.05 mm (depending on the requirements for the part being manufactured)). They come in two main types: overhead (in the form of slabs) and box-shaped, which are three-dimensional structures. There are also jigs for mixed type drilling. These devices are used to reduce labor intensity: from technological process When processing the part, the marking operation is eliminated, in addition, it becomes possible to drill several holes at the same time.
The drilling jig is used only in serial and mass production. This is explained by the fact that for a small batch of parts it is not practical to make a separate device, which, moreover, will have to be installed and configured separately.
A drilling jig is usually used to process several holes lying in the same plane. It is best if the parts are unified by standard size, this will allow the device to be used for a wide range of products.
The drilling jig is also used in light industry and construction. Such devices are only of the overhead type and are made of lighter materials, such as wood or plexiglass. These products are not designed for great accuracy; the positioning error is only ±0.5 mm. But this is more than enough to make holes for fittings in furniture or drill a series of holes in the wall of the house. The equipment used is a regular drill or a tabletop drill press.
You can make your own conductor for household needs. It will be needed during repairs, when you need to make a lot of the same type of holes and there is no desire to waste time on preliminary marking. To make it, you can use any available materials: mark and drill everything on a sheet of metal or a wooden board required holes which will serve as guides. If necessary, an additional plumb line is made so that shavings or concrete chips do not fall on the floor. You can make a dust-free jig when the template is covered with a specially fitted half of a plastic bottle.
The main advantages of these devices are the high accuracy of hole positioning without preliminary marking, high performance labor and reducing perpendicularity deviation (due to guide bushings). However, using a jig for drilling is not always economically justified, especially with small batches of parts in production.
When furniture is created, almost all parts have to be joined end-to-end. This is done using dowels in which holes are made. This is where a special part is needed. You can buy it or make a furniture jig with your own hands.
What is a furniture conductor?
A jig is a bar that has several holes and sleeves. It is applied to the required part, insert the drill into the sleeve and make a hole. To secure two parts you will need the help of one conductor, and the parts are fixed as securely as possible.
Advantages of a conductor:
- precision drilling;
- simple and fast hole creation.
At the same time, conductors are used not only during construction, but also in mechanical engineering. This device also allows you to drill cylindrical blanks and pipes.
Different types of conductors
Depending on the industry, conductors are divided as follows:
- Invoices. They got their name because of their area of application. This device is applied to the workpiece and fixed, with the help of which holes are made.
- Rotary. They are used to drill cylindrical holes. In this case, the rotary axes can be located horizontally, vertically, or at an angle. The body here is equipped with rotary bushings.
- Tiltable. They are used when holes are created in several planes.
- Sliding. Used to make each individual hole. In this case, this model is not fixed to the surface, which means it is not the most convenient.
DIY furniture conductor
As we already wrote above, this product is needed when assembling furniture. Some people prefer to buy it, while others prefer to make it furniture holes with your own hands. Such products are sold in any construction stores, it is important to choose here finished products for a specific purpose. The cost of a furniture jig will depend on its size, purpose and manufacturer.
The simplest option is inexpensive, but professional equipment with various additional functions costs quite a lot. Therefore, today they are increasingly making furniture jigs and templates with their own hands.
They are produced using metal sheet or wooden board. Holes are made in them that will serve as guides. This work is not difficult, anyone can cope with it.
How to create a conductor
So, creating a furniture jig with your own hands is not difficult. To get started you will need:
- welding machine;
- Bulgarian;
- drill and some plumbing tools;
- You also need to prepare 10 x 10 mm reinforcement in advance.
First, the workpiece is cleaned with sandpaper and markings are made. The distance from center to center is approximately 32mm. Next, each template hole is drilled. After this, a stop is created - for this you can take a metal plate 1 mm thick. It needs to be bent and prepared for carving. The last step is connecting these parts.
The product must be made as accurately and carefully as possible, otherwise it will be of no use, and in an unfavorable situation, it can even damage the furniture. You can learn more about how to make a conductor by watching various video tutorials. The easiest way to do it is by furniture template, which can also be seen from specialists.
To ensure that drilling does not cause complications, a conductor is needed. This device will really be needed when assembling furniture. Of course, today you can buy everything, but it is better to make a furniture jig with your own hands, because then such equipment will definitely be suitable for each specific purpose.
