In the online store site you can buy necessary elements for sharpening stones affordable prices by placing an order online through the “Cart”. If you have any difficulties, our consultants will help you make your choice.
If you decide not to buy sharpening machine, but to make it yourself using your own engine, you will need the services of a turner. Making rather than buying is often justified for several reasons: it turns out cheaper, it turns out to be of much higher quality, it’s no secret that sharpening machines sold in stores sometimes hit the stone mercilessly. Eliminating the runout of a factory sharpener is no easier than making a good machine.
We manufacture two types of machines:
- The stone is installed through a nozzle on the engine. Advantage - simplicity, disadvantage - you can install only one stone. You can install two stones, but at the cost of removing the engine cooling system. The impeller has to be removed.
- The axle with two stones at the ends and a pulley in the middle is driven by a separate motor. With this option, the beating of stones is minimal, the engine is perfectly cooled and does not become clogged with abrasive particles. This system works many times longer. This scheme is suitable for grinding and cutting diamond tool both with water supply and without water.
We can manufacture a sharpening or cutting machine, complete with everything necessary. We can also use your components: motor, bearings, metal blanks, belts, etc. We can manufacture a machine according to your drawings and wishes, which will be very significantly cheaper, but no worse in quality.
If you need to make attachments for hand power tools: drill, dremel, sanders, we will help you. The precision of our machines is quite enough so that the nozzle does not vibrate even at a speed of 20,000 revolutions.
Do you have an old washing machine that is beyond repair? Don’t rush to get rid of it, from this article you will learn how to get rid of the engine washing machine make emery.
A homemade sharpener made from a motor will always come in handy on the farm and for household needs. Moreover, industrial sandpapers are expensive in stores, while grinder from automatic washing machine will cost free.
An emery machine is useful for the following work:
- Restoring the cutting qualities of the drill. To avoid buying new drills, you need to know how to sharpen old ones. When working with a drill, the drill gets very hot, which is why it constantly becomes dull. Once you sharpen it on a machine, you can use it many more times.
- Sharpening knives, scissors, shovels and other tools. Thanks to homemade machine from the washing engine, your knives will always be sharpened, and your scissors will cut perfectly. You don't need to use any special effort for this.
- If you replace emery wheel on a polishing machine, you can easily process products and parts.
Using the motor from the washing machine, you can make a sharpening machine with your own hands. To do this, you will have to buy just one part - an emery wheel. All other components are located in the motor.
Which engine is suitable for making emery?
Wondering what engine you can use? You can use any motor from a washing machine, even the brands “Vyatka”, “Riga” or “Volga”. The main thing is that it has sufficient power.
For normal operation grinder, a power of 100-200 W is enough, with 1000-1500 rpm. For particularly large parts, a 400 W motor is suitable. But if the engine speed reaches 3000 rpm, it needs to be adjusted or a very durable disc installed.
What you need to create emery from a washing machine motor
To make a simple sharpening machine you will need:
- washing machine motor;
- flange;
- sleeve;
- attachment to the electric motor (emery wheel);
- casing for protection;
- support;
- starting device.
When purchasing, it is better to choose a product with two circles: a finishing and a rough version.
You also need to make an adapter with a flange. Since the size of the shaft does not match the hole of the grindstone, an adapter must be made. It can be done on a lathe, having previously determined the dimensions and completed the drawing. On the diagram you need to mark the diameter of the shaft and the emery hole.
You can make a flange for the shaft yourself. A piece of pipe with a diameter of 32 mm, no more than 200 mm in length, will do. It should fit perfectly on the motor shaft. On one side of the flange there is a thread, the direction of which depends on the direction of movement of the shaft. When sent to the engine, the other end of the flange is heated and pressed.
After installation, be sure to secure the flange. This can be done by welding or bolting, drilling the flange with the shaft.
The shaft adapter is ready. It remains to install the element for sharpening the cutters.
Steps for creating emery from a washing machine engine with your own hands
For homemade device A belt driven motor will come in handy.
All that remains is to assemble the device correctly. After installing the flange, put the nut and washer on the shaft, then a large emery wheel, and then the nut and washer again.
Motor connection
How to connect the motor from an automatic washing machine:
- Using a multimeter tester, look for the tachogenerator wires that show a resistance of 70 ohms (usually they white). We will not use them.
- There are four wires left. Using a multimeter, you need to identify paired wires.
- Connect the wires leading to the stator and to the electric brushes. The remaining wires need to be connected to a wire and a plug at the end, and then connected to the network.
- Connections must be insulated.
Immediately after connection, the motor for home emery will start working, and you will be able to evaluate the functionality of the device.
Connecting the electric motor of Soviet-made washing machines differs from the previous version.
- Here you will find only 4 wires. We need to find pairs.
- Take a multimeter and measure the readings of each wire. You need paired wires with lower resistance that go to the working winding.
- Connect these wires to a plug and connect to the network.
- Now we need to make a trigger element. You can use any button, for example from door lock. Connect one wire coming from the button to the starting wire (PO), and the other to the working wire (OB).
The motor is now connected. But before starting work, you need to thoroughly secure the machine to avoid an emergency.
How to set up an emery machine and make a protection
How to secure emery machine and put protection on it? You can screw it to a workbench.
To do this, use the bracket that is in the washing machine. To reduce vibration during operation, rubber gaskets are placed on the corner, which can be made from a piece of hose.
If the device is installed on wooden workbench, cover it with a sheet of metal on top to prevent fire.
For your own protection while using the machine, install a metal arc over the disk. You can also enhance the protection by attaching 5 mm thick plexiglass to the pendants. The glass can be raised and lowered using hangers. 
Making a sharpening machine yourself is not difficult. The main thing is to secure it and connect it correctly. Also follow safety rules when working, use safety glasses and special clothing.
There are many models of electric emery on the market, but its design is so simple that you don’t want to spend even minimal money, especially since it’s easy to make it yourself. You only have to buy abrasive wheel, and the “donor” of the engine will be an old washing machine, which will probably gather dust in the garage and, most likely, will never be needed again. Read on to learn how to make sandpaper from a washing machine motor.
What determines the choice of motor?
First of all, it should be explained why, in most cases, a motor from a washing machine is used in the manufacture of a sharpener. The fact is that old models, such as Volga, Chaika, Ural and many others, had ideal speeds for sanding, 1000 - 1500 per minute. It was this frequency that allowed their activator to spin at optimal speed. At the same time, washing machines varied quite significantly in maximum load, and therefore in engine power. In most cases it ranged from 200 to 400 watts. This is quite enough so that even axes can be sharpened with sandpaper.
However, before you start manufacturing, you must definitely study the “nameplate” on the engine body. This is a tin plate on which the main parameters of the motor are indicated. It is important that the shaft rotation speed does not exceed 3000 rpm. This is due to the fact that grinding wheel It is not designed for high angular velocity and if the maximum value is exceeded, it may collapse. This is very dangerous, especially considering that most homemade sandpapers lack protection. Moreover, a high rotation speed will lead to overheating of the sharpened tool, and hence to loss of cutting qualities.
In addition to optimal frequency and power, the washing machine motor has a number of significant advantages:
- Connection to electrical network without additional modification.
- The existing mounts make it easy to mount the engine to the sandpaper base.
- The length of the motor shaft allows it to be placed on it grindstone, albeit with the help of an adapter.
Now that the choice of motor for the emery is justified, we can move on to the process of its manufacture.
This is the only detail that cannot be made by hand. Required lathe and, accordingly, a person who knows how to work on it. What is the adapter for? The fact is that the size of the motor shaft is about 14mm, while the mounting hole
The emery circle usually has a diameter of 32 mm. This means that their “direct” connection is absolutely excluded. The adapter seems to increase the washing machine motor shaft to the required size.
To make it, you will need a piece of round steel, approximately 65 mm long. and diameter 60 mm. The last figure is due to the need for the so-called flange - a fixed washer on the body of the part, into which a circle of emery rests on one side. Its thickness must be at least 4 mm. It is turned in front of the flange seat, diameter 32mm. Next comes the “M20” thread, onto which the nut that secures the circle will be screwed.
For mounting on the engine, a hole is made in the adapter body with a diameter equal to the shaft. Then everything depends on how the pulley was fixed on the washing machine. There were two main options:
- Using a thread on the motor shaft and a large nut.
- Bolt 4, screwed into the adapter body, perpendicular to the longitudinal axis of the motor.
The part being manufactured must have one of the following mounting methods, depending on the type of engine.
Sometimes, home craftsmen try to minimize costs and make an adapter with a flange themselves. Most often, a pipe with suitable internal and external diameters is used as a base. You shouldn't do this without proper experience. The fact is that it is very difficult to select a suitable workpiece, so “beats” and distortions are inevitable. It will be unsafe to work with such emery. You should not save on your health, especially since the cost of a master’s work will not exceed 500 rubles, and if the part is made from its own material, it will cost even less.
Another adapter diagram for making emery from a washing machine engine
The frame on which the engine will be mounted does not require any special material costs, but this does not make it any less significant. The base must be well thought out, since making emery is not an end in itself; you still have to work on it. At the same time, all attention should be focused on sharpening the tool, and not on holding the motor jumping all over the workbench with your hand. Working like this is at least inconvenient, but about compliance with safety regulations, in in this case, there is no question at all.
Therefore, the base of the emery should be heavy enough, and most importantly, allow the motor to be fixed in the same way as it was fixed to the washing machine. It is best, of course, to make the frame metal. True, you will have to use welding for this. If this is not possible, then you should take a suitable piece of chipboard and bolt it to it. metal corners for engine mounting. Even better, remove the motor from the washing machine along with the standard bracket and screw it to the base. The main thing is to use bolts and nuts for this; self-tapping screws can become loose and unscrew due to vibration.
There is one more key point. The height of the motor mounting should not only allow the emery wheel to rotate freely, but also provide a gap of 4 - 5 cm between it and the base. After the motor is securely mounted on the frame, you need to think about the support table. It must be metal; welding can be replaced with a bolted connection. If the starting capacitor on the washing machine was moved outside the motor housing, you need to provide a place for it on the base of the sandpaper.
After the motor is securely fastened to the frame and all auxiliary elements, you can go to electrical connections. But first you need to make sure that the grinding wheel is securely fastened to the motor shaft, as well as that there are no various beats.
Connecting the electric motor
First of all, it is necessary to recall the safety rules. AC voltage 220 volts is life-threatening. Therefore, before connecting the wires and motor terminals, you must make sure that they are disconnected from the electrical network.
The electric motor from a Soviet washing machine cannot simply be plugged into an outlet. Or rather, it is possible, but first its windings must be connected in the appropriate way. The motor from an automatic washing machine is easier to connect, since it is asynchronous. It is enough to connect the rotor and stator windings in series. The Soviet washing machine had a synchronous motor. Its two windings, starting and working, are routed through the housing with four wires.
When making emery, the simplest and most correct thing is to transfer the entire wiring diagram of the washing machine to the frame, with the exception, of course, of the timer. If this is not possible, then you will have to remember the school physics course and connect the windings yourself. The most difficult thing is to identify them correctly. The fact is that the wires usually do not have any markings. You'll have to take a multimeter and measure the resistance. A value of about 30 Ohms will correspond to the starting winding, and 20 Ohms will correspond to the working winding. Now it is enough to “twist” them in parallel and connect them to the network connection cord, but there is one important nuance.
The starting winding should be energized only while the emery motor is spinning up. After the motor reaches the required speed, it must be turned off. Otherwise, it will get very hot and quickly fail. Therefore, in the open circuit of the primary winding, a button with normally open contacts, for example from a doorbell, is switched on. The emery switch and the start button are installed on a plate made of insulating material, in an easily accessible place. All connections are carefully insulated. The emery is ready, you can connect it to the network. After starting, the engine should run without any extraneous sounds, vibration or strong heat.
In addition, from a used washing machine you can also construct:

- electric bike,

- concrete mixer,
- lathe,
