Lining is a common finishing material that has gained popularity due to its advantages: environmental friendliness, ease of processing and attractive appearance.

Cladding boards can be purchased at finished form, or you can make it yourself using a special woodworking machine.

Let's look at what a machine for making lining is, what models are used in production and at home, and how not to make a mistake when choosing woodworking equipment.

Application of lining: advantages and disadvantages of facing material

Despite the abundance of modern finishing materials, such as plastic and plasterboard, wood still remains on the list of the most popular building materials.

Lining is very popular - a planed board made of deciduous or coniferous wood with the same type of joining elements (tongue and groove), which has a natural level of humidity.

Lining is universal building material, which is used for outdoor and interior decoration residential premises, verandas, gazebos, loggias, etc.

The advantages and disadvantages of lining largely depend on the type of wood, but there are also general advantages of this material:


The disadvantages of wooden lining include:

  1. The cost of lining is higher than the cost of plastic and drywall.
  2. Wood is a flammable material, so when using it you must strictly adhere to fire safety rules.

Do I need to buy a machine for making lining?

Even the most primitive machine for making lining is not cheap, so before purchasing it you need to determine for yourself: will such an acquisition be profitable?

Arguments in favor of buying a machine for making lining:


If a small amount of lining is required for the implementation of the project, and organizing a wood processing business is not included in the immediate plans, then at home you can use a manual milling machine or homemade machine for the manufacture of lining.

Description and principle of operation of the machine for making lining

The shaped profile of the lining is the result of processing lumber using special cutters.

The lining profile can be formed using conventional milling equipment, but a single-profile machine can only process one side of the workpiece in one pass, and other tools will have to be used to grind and process other sides of the board. This option is not suitable for mass production of lining, since the productivity of such machines will be too low.

More convenient is a four-sided multi-spindle machine that processes wood raw materials on four sides simultaneously. The finished product is produced in one pass of the working material.

Machines for lining have the following technical features:


The main components of a woodworking machine for lining are:


The rotation speed of workpieces on factory machines reaches about 5000 rpm - this ensures high-quality surface treatment of the material

In the presence of additional equipment it is possible to establish a full cycle of lining production. For this, in addition to a machine for making lining, you will need:


Before making a purchase, you need to choose the optimal machine model and check the quality of the equipment.

When choosing the type of machine for lining, you should consider:


If used correctly and carefully, a machine for making lining will be an excellent help during construction, and the cost of purchasing it will quickly pay off if you set up the production of lining to order.

Special machines are used for sharpening knives of planer and jointer types. The work can be done with your own hands; the machine can be assembled independently if necessary. Sharpening is carried out according to certain rules, several options are used. You need to be careful and not violate the technology.

Otherwise, knives for planers, jointers and planers will be poorly processed and will not be able to fully perform their functions. In addition to special equipment, sharpening stones can be used for sharpening, but a small sharpening machine that has cooling is best suited for the job.

Preparatory work

Anyone who has a plane or jointer faces the problem of sharpening knives. It is expensive to constantly buy new ones, especially since knives can be easily sharpened with your own hands using special machines or sharpening stones. If the jointer is used frequently, like other woodworking equipment, then it will be inconvenient to constantly send knives to the workshop for sharpening. It is better to assemble the machine yourself. To ensure that the jointer is always in working order, it is recommended to sharpen it at home. The easiest way to do this is with a regular sharpener. You only need to take a sharpener with low speed, its quality should be high. Water cooling must be available.

You can also use a sharpening stone, but it must first be leveled with a special device. Usually it comes complete with a small sharpening machine, so there is no need to additionally look for such devices. After the editing is completed, it is necessary to smooth the stone; a block is used for this. Sharpening a jointer knife without this step will be problematic.

What to do next? You need to set the angle of inclination. A special screw will allow you to correctly secure the blade relative to the position of the sharpening stone. Using this screw, you can subsequently set any angle of inclination of the knife. Next, take the holder that comes with the machine. A jointing knife is installed in it. Experts advise starting sharpening knives with a width of at least 13 mm. The length is not critical; if necessary, the knife holder can be rearranged to any position.

The knife must be securely fastened in the holder, otherwise sharpening will be carried out skewed, and this will worsen the quality of the jointer. How to properly secure a knife in a holder? While holding the blade in the desired position, tighten the clamping screws until they stop. To control the sharpening angle, you must use a marker; it marks the sharpened chamfer of the knife. It is with the help of this simple method you can easily monitor the quality and progress of work. The sharpening will be correct if the corner of the knife touches the stone. The stone must be rotated manually to determine if further adjustment is necessary.

Sharpening process and operating rules

The holder moves to the right and left, movements are made relative to the sharpening stone. The blade should not be allowed to go beyond the edge. It is best to immediately install the holder 12 mm from the edge of the working circle. If sharpening is carried out, water cooling must be supplied. You will have to add water to the tank, you need to make sure that it does not run out. It is necessary to ensure that water does not accumulate on the floor near your feet. This is done for security reasons.

When performing work, you must ensure that the stone remains clean at all times, as it gets dirty quite quickly. A special whetstone is used for cleaning; it is recommended to carry out this procedure frequently, since only clean stones can be used for sharpening. The choice of stone itself depends on what kind of knives are used. Today, manufacturers produce jointing knives from soft or hard tool steel, so operating conditions will vary.

Sharpening takes approximately 20 minutes, then fine-tuning is done. A special paste is used for this. After polishing, there should be no burrs left on the surface, otherwise the jointing knife will not be ready for use. The test is simple to carry out; a finished knife with excellent sharpening should easily and evenly cut a sheet of paper while hanging, leaving a neat cut.

How to make a machine with your own hands?

To sharpen a jointer knife, you need to use special sharpening machines. This is especially important when jointers, planers and other woodworking equipment are used frequently. The sharpening machine is compact in size and can be installed even in a garage or small shed. summer cottage. Before starting assembly, you must prepare the appropriate tools that will be used during assembly of the sharpening machine:

  • the table on which the work will be carried out;
  • faceplate;
  • vacuum cleaner;
  • engine;
  • casing for the machine.

You need to start assembling the machine by finding a suitable faceplate. It is one of the most important parts for a sharpening machine. All jointer knives are quite narrow, so they can only be sharpened using a suitable type of faceplate. Then the sharpening work will be high-quality, safe, and fast. The faceplate takes up the bulk of the cost of all equipment. It’s more profitable to make a sharpening machine yourself; you won’t need expensive parts for it. Manufacturing will be quite justified if you have to frequently carry out woodworking.

You need to buy new faceplates; it is recommended to take American or German-made elements. They have the highest quality, and the cost fluctuates around 25,000 rubles. Next, you need to select a motor for the future sharpening machine, it is best to take a 1-1.5 kW motor, you can even use a used element. Motors from old ones are excellent for the machine. washing machines, but first you need to make sure the engine is working.

The motor is mounted under the tabletop, the faceplate is mounted to the moving part.

It is imperative to provide a button to turn the machine on/off. It should be located within reach of your hand. The faceplate is covered on top with a casing, which is made in the form of a square. One corner of the casing must be cut off, since from this side the jointing knives will be sharpened with your own hands. A hole is made in the lower part of the tabletop; it will be intended for a vacuum cleaner pipe, with the help of which all contaminants that arise during sharpening will be removed. In addition to sharpening jointing knives, a similar machine can be used for other work, for example, for processing ax blades, saws and other tools used in the garden.

Jointer knives can be sharpened various methods. Special sharpening stones are suitable for this. However, you can assemble a compact sharpening machine yourself. It will be used to sharpen a variety of tools including saws and axes.

The sharpness of a knife is one of the main parameters affecting the quality of wood processing. Besides, this characteristic also affects the degree of safety.

Often a person does not want to run around over and over again in search of a place where he could bring his cutting tools into proper condition. In this case, it’s time for him to think about making a homemade sharpening machine that would solve the issue of the sharpness of planing knives once and for all.

The development of industrial equipment does not stand still. Happens all the time rapid growth requirements for speed and, most importantly, for the quality of material processing. In this regard, there is a need to create cutting tools with high parameters.

One of the main problems that arise during the work process is sharpening knives. This is what determines the basic capabilities of the machines and their suitability for use.

Homemade sharpening machine.

Depending on the tasks to be solved, such devices are divided into two types: universal and special. The first are sharpening devices for the surfaces of most cutting elements. They are equipped with a variety of devices that allow you to secure, install and sharpen knives.

All units are equipped with various equipment, which determines the degree of automation and control of the accuracy of the work performed. there are also different ones. These can be stationary devices or temporary ones that can be placed on any horizontal surfaces.

Despite the wide range of types of equipment offered, in order to save money, a knife sharpening machine can be made by hand.

Homemade units can, in some cases, even be more convenient than purchased options. This is due to the fact that the master independently decides what characteristics this device should have.

Although, of course, many models of universal devices allow you to choose the most suitable type equipment capable of solving the assigned tasks.

Homemade knife sharpening machine

Most often due to two reasons. The first is the desire to save money. The second is to show your skill and do everything with your own hands exactly as your soul desires.

Drawing of the machine device.

For example, very often you may be faced with the need to tidy up only certain tools. These can be drills, cutters, saws or jointing knives.

Each specific case requires a separate approach. Self-assembly The machine will allow you to make a convenient unit for working with certain elements.

Among other things, the presence of sharpening units will significantly save costs aimed at purchasing new knives or restoring them in third-party workshops.

If you need to professionally sharpen the tools listed above, then you should still give preference to purchased devices. They are more thoughtful and elaborate.

In addition, purchasing in a store guarantees that the device will solve the assigned tasks for a long time. You should also remember the degree of automation. Of course, professional devices use electronics that are simply impossible to make at home without the proper experience.

Option 1

For sharpening planer will not only support the instrument in in good condition, but will also save time on trips to other workshops.

One option for creating such a device is to use a motor with an abrasive wheel, emery cloth, or a sharpening device with a knife fixed in it.

Homemade machine for sharpening planing knives.

This device can be made partly from aluminum, metal and wood. In this case, bearings and guides are used, made from scrap materials, for example, pipe corners or others.

When the knives are level, they can be sharpened on a large abrasive stone. If this is not available, you should use sandpaper glued to a flat surface.

Depending on the requirements for the final result, you can vary the speed of this process. If there are dents, you must first use a belt sander, and at the final stage, treat the tool with an abrasive stone or a homemade one made from sandpaper.

The design features of the machines may also differ from each other. The first option is a device with a fixed base. Its angle of inclination can be changed, but otherwise it is in a fixed position.

The bar is attached to a rod, which is inserted into the loop of a movable clamp located on another rod. The disadvantage of this design is the “walking” angle due to the lack of rigid fixation.

The knife is installed using two steel plates fixed to a fixed platform. Having loosened the fasteners, insert the blade and clamp it. Then adjust the height of the bar so that the required angle is set.

Option 2

The second type of design provides a movable platform, as well as a magnetic holder. This option does not have the disadvantages of the previous unit. motionless in this device It turns out there is a frame with a bar that determines the angle.

The knife, in turn, is mounted on a movable table. The choice of holder remains with the master. You can use a magnetic type or a regular one, made of metal plates and “lambs”.

An important requirement for such equipment is the movement of the table with the cutting tool along a strictly horizontal surface. It is best to use a polymer or marble countertop.

The principle of sharpening knives on a machine.

As you can see, sharpening knives is not that difficult. If any problems arise, you can always take the help of training videos from the Internet. If all instructions are followed correctly, anyone can make such equipment.

Bottom line

Knife sharpening machine – necessary equipment in the workshop of every craftsman who works with wood. A timely solution to the problem of sharpening knives will not only speed up the process of processing the material, but will also save time and money.

Why go to other workshops if you can make the necessary equipment yourself?

Owners of planing machines and electric planers periodically face the problem of sharpening cutting edges. A well-sharpened tool will ensure clean wood processing even at non-ideal angles and speeds. The easiest way is to sharpen knives and knife heads with your own hands using specialized equipment.

Knife sharpening is necessary

Planing knives require timely care because:

  • blunt surfaces process wood poorly;
  • when processing soft rocks with dull knives, the surface becomes covered with lint and unevenness;
  • worn edges crumble;
  • During planing with blunt edges, the engine and power units are overloaded.

Attempts to sharpen blades with your own hands using diamond stones, as a rule, give short-term results. Due to poor quality of editing, the blades have to be sharpened soon. Therefore, professional carpenters use only mechanical sharpening.

Types and designs of machines

The machines on the market are distinguished by the knife feeding mechanism:

  • manually;
  • automatically.

The machine for sharpening planing knives with manual feed consists of:

  • grounds;
  • abrasive stone;
  • carriages for fixing the knife.

During processing, the cutter moves forward with the help of a handle. Transverse movement of the cutter is ensured by a flywheel.

Automatic machines differ in size and range of options. Mechanisms for industrial applications installed on a powerful cast iron frame. The carriage is equipped with a support. You can set the speed of movement of the blade and the thickness of the metal layer being removed. Industrial machines allow you to simultaneously sharpen several planer blades without changing settings.

Table 1. Characteristics of some models of machines for sharpening planing knives

Compact automatic machines for home and small workshops are designed to process one cutter in one go. They also provide speed control and automatic tool feeding.

Before starting work on any sharpening equipment, you should make sure that the frame is securely fastened. Vibration of the machine impairs the quality of sharpening and can lead to injury to the operator.

Basic rules for using manual feed equipment

Such machines are used for one-time work and for sharpening small batches of blades with your own hands, since the processing process is quite long.

  • Before starting work, you need to make sure that the grinding surface is clean, without stains or streaks.
  • The movement of the carriage should be smooth, without jerks or jolts. It is forbidden to stop it when the cutter approaches the sharpener.
  • The faster the carriage moves, the lower the quality of sharpening. The optimal speed of movement is 5 - 6 m/minute.
  • For proper sharpening, the range of motion of the carriage is important. During a pass in each direction, it should move 10 - 13 cm further than the end of the knife. This ensures optimal contact between the cutter and the sharpener, which must be broken before moving in the opposite direction.

Basic rules for working on automatic machines

  • Planing knives can be sharpened dry or wet. In the second case, the blade is constantly washed with a stream of water. The wet method is gentler on the blade and more effective;
  • Before processing begins, it is necessary to set the following parameters: sharpening angle, amplitude of carriage movement. The amplitude should be 15 cm greater than the length of the knife;
  • The blades are carefully fixed in the mobile carriage with your own hands.

Homemade machine for sharpening planing knives

The design, made at home with your own hands, allows you to quickly and efficiently sharpen knives to one set angle. This will change the factory angle, so all blades will need to be re-sharpened. The quality of planing will not deteriorate, but may even improve.

To make a device for sharpening straight blades of planing, jointing and thicknessing machines with your own hands, you need:

  • metal corner No. 50;
  • round pipe with a diameter of no more than 50 mm;
  • electric motor from a washing machine;
  • powerful spring;
  • bolt with nut;
  • plastic handle (knob);
  • Bulgarian;
  • welding machine.

Making a machine with your own hands.

  1. Cut a corner about 50 cm long.
  2. We bend two pieces of pipe so that we get a stable stand for the corner, and weld the legs. The corner should be positioned vertically towards the master.
  3. At the left end, behind the corner, we attach an electric motor. It is placed on two points: a rigid axis and a powerful spring; The spring is tightened and released using the adjusting screw, moving the motor closer or further from the guide-angle.
  4. We put an abrasive wheel on the electric motor shaft.
  5. The engine is started by a switch located on the frame in a convenient location.
  6. We feed the tool using homemade vise from a piece of pipe 25 cm long, a pressure plate, a bolt with a nut and a knob. We clamp the knife in a vice and move it along the guide, holding it by the knob.

Sharpening knives for woodworking machines is a mandatory process that can be done with your own hands using special tools. Sharpening is the restoration of the previous cutting capabilities of hacksaws, scissor shafts, planers, jointers and other devices for wood processing.

  • To sharpen the blade shaft of a planer or jointer, you will need the appropriate device;
  • The sharpening work is done by hand;
  • Craftsmen learned to assemble sharpening devices;
  • When restoring hacksaws, jointing devices, sharpening knife shafts, be sure to follow several recommendations and strictly follow the technology;
  • If the teeth of hacksaws and knife shafts are sharpened incorrectly, the quality of wood processing with tools will significantly deteriorate;
  • Sharpening stones are a good alternative for a sharpening machine. But if you have the opportunity to assemble it yourself or purchase a sharpening machine, be sure to take advantage of it.

Preparatory activities

If you need to sharpen knives for a woodworking machine, you should start with the required preparation steps. It is not so important what parameters the knife shaft or cutting sheets of hacksaws have 13 mm, 20 mm or all 200 mm, they will definitely need sharpening.

Some people prefer to send dull shafts to special workshops, where they can easily restore the previous sharpness of a 200 mm knife or small cutter lathe. But both ordering sharpening and buying new knife shafts is a financially expensive matter.

Preparation for sharpening begins with familiarization with the available means of restoring the surfaces of cutting tools and some recommendations.

  1. To keep jointers, planers, and hacksaws in working order, assemble or purchase an appropriate sharpening device.
  2. Simplest, a budget option is a whetstone. But the quality of processing directly depends on your skills in working with stone. If there are none, achieve the required level sharpening is extremely difficult. Plus, stones are not able to cope with all types of cutting tools that are equipped with modern woodworking machines.
  3. Choose a machine that can sharpen at low speeds, as this has a positive effect on the quality of the finish.
  4. The recommended equipment for a sharpening machine is a water cooling system.
  5. Carefully study the equipment of household woodworking machines. Often there is already a sharpening stone, which is optimally suited for processing the knives used.
  6. If the stone is not included in the package, it will have to be purchased separately, leveled with a special device, and smoothed. This is the only way you can sharpen the knife shafts of jointing machines with high quality.
  7. The machines have a function for setting the angle of inclination, which is adjusted with a special screw. By turning the screw and changing the position of the sharpening device, you can correctly fix the tool relative to the stone.
  8. Next preparatory stage- This is a holder in which the knife shaft is installed.
  9. If you are a beginner, it is not recommended to start your first job with 200 mm knives. Start literally with 13-15 mm, and gradually you will learn to process 200 mm and even 2 mm. To do this you need to accumulate some experience.
  10. The length of the knife is not a fundamental parameter, since the knife in the holder can move to the distance you require.
  11. Make sure to hold the shaft firmly in place. Otherwise, you will get a significant distortion, due to which the quality of woodworking will suffer.
  12. Study the operating manual of the purchased sharpening machine in detail. If this is a DIY tool, you will have to rely on drawings and available information on the Internet about a specific sharpening device project.

Sharpening

In order for the sharpening of knives for a woodworking machine to give a positive result, you can resume working with the equipment at the same level of quality, you need to adhere to a few fairly simple rules.

  1. The sharpener holder can move left and right relative to the stone to sharpen knives.
  2. Do not allow the blade to end up over the edge.
  3. Immediately fix the holder at a distance of 12 mm from the edge of the grinding wheel.
  4. When sharpening knives of 200 mm or smaller variations, make sure that the water cooling function is activated on the machine.
  5. The cooling system requires constant monitoring. The tank usually has a small volume, so water needs to be added periodically. If it runs out and the sharpening process continues without cooling, you risk ruining a rather expensive knife.
  6. As the knives are processed, water from the cooling system may accumulate on the floor. Since sharpening machines are electrical devices, ensure that water is drained away from your feet and wear rubber shoes. In any case, standing in a puddle of water while working with an electric machine is always dangerous. Follow safety regulations.
  7. Keep the whetstone clean. It gets dirty quite quickly with active use.
  8. The grinding wheels of machines are cleaned using special device. The machines should be equipped with this cleaning bar, but if it is not included in the set, then you will have to purchase it separately.
  9. Each subsequent sharpening, according to the operating rules, is performed only on the condition that the stone is cleaned. Therefore, after each sharpening, arm yourself with a cleaning bar and treat the machine with it.
  10. On average, sharpening using a special machine takes about 10-20 minutes. It all depends on the type and size of the tool that became dull as a result of woodworking operations.
  11. After sharpening the tools of woodworking machines, do not rush to return them to their place and continue working. After processing on the machine, the tool needs to be fine-tuned.
  12. Finishing consists of applying a special paste to the surface of the cutting element. Proceed according to the instructions provided by the manufacturer of the finishing paste on the packaging. Different pastes may differ slightly in application methods.

If you did everything correctly, then the knife should be perfectly smooth, sharply sharpened, and free of any irregularities or burrs. Don't worry when the result doesn't meet your expectations the first time. This takes some time and a little experience. That’s why you should start with simple and inexpensive knives that you don’t mind ruining.
