Grinding machine from a washing machine motor

Grinding machine from a washing machine motor Old household appliances are an excellent basis for homemade projects. Especially if the motors remain in good working order - even asynchronous ones. Despite their low power and low speed, the devices’ decent torque allows you to make a disc grinder that is useful in everyday life.

Making a grinding machine from a washing machine engine is quite simple: with a minimum of components and tools. We will analyze in detail the assembly instructions and the nuances of using the device.

What do you need for homemade?

It will not be possible to make a grinding machine from one engine from a washing machine. In addition to the motor itself, additional materials and tools will be required. To avoid spending too much, it is recommended to first look at the items you have on hand. Perhaps among them there is something suitable for a frame: an old cabinet, pallet or drawer.

You can make a mobile grinding machine from a washing machine motor.

You can use the approximate list of materials as a guide. So, for the base you will need boards and bars with a thickness of 2.5 cm - for a reliable frame. To connect the machine to the electrical network, you need a switch and a power cable with a plug. The engine is fixed to the tabletop using metal corners. It is also necessary to have sandpaper of any grain size, which will perform the sanding function of the future product. You will also need consumables: screws, bolts, nuts and wood glue. standard garage tool set

The tools you need to prepare are:

drill;
screwdriver;
jigsaw;
iron;
grinder with petal disc;
ruler or meter;
building level;
marker.

The first step is to check the serviceability of the engine for a homemade machine. If the motor is running and all materials and tools have been found, you can begin assembly.

How is the machine made?

The process of making a grinding machine from an old washing machine motor can be divided into four stages. At the first stage, the wooden “foundation” is assembled, at the second, the grinding disc is cut out and fixed on the shaft, at the third, the entire structure is assembled, and at the final stage, the sandpaper is installed and the unit is tested. Let's look at each step in more detail.

First you need to assemble the bed - the stationary base of the machine. It is not necessary to make a table from scratch: you can remake an old cabinet, drawer or shelf. The main thing is that the support is strong, stable and easy to use.

You can use an old cabinet or drawer as a frame.

If there is no old table, then a new one is assembled with your own hands. The instructions are as follows:

saw off two identical bars (for “legs”) and a tabletop from a 2.5 cm thick board;
fold the resulting planks into a “p”-shaped structure;
fasten the table with self-tapping screws;
strengthen the structure with jibs or crossbars;
add stability to the support by screwing a block perpendicularly to each leg.

You should get the simplest wooden table. If desired, the structure can be sanded, varnished or painted to add aesthetics and extend the life of the product.

The second step is to make and install a grinding disc. The sequence of actions is as follows:

take a wide board;
draw a circle of the required diameter on the board and cut it with a jigsaw;
grind the edge of the disc;
Use a drill to drill holes for the bolts on the motor pulley (be sure to cover the rest of the motor surface with a rag to protect it from dust and chips);
drill corresponding holes on the wooden disk;
fix the disc on the pulley with bolts and nuts.

Next, the engine is fixed on the table. For this, wooden planks and steel corners are used to connect the elements together. If the motor is taken from an activator washing machine, it is recommended to keep the factory motor housing. This move will protect not only the motor from dust, but also the user, ensuring safe operation of the grinding machine.

The next step is to connect the power cord with a switch to the motor. We immediately launch it at full power to ensure the stability of the structure. If you have experience, you can make two speeds on the grinding machine at once: fast and slow.

If desired, you can set the engine to two speeds - fast and slow.

Then you should do:

ideally grind the disc with a grinder with a flap wheel or a chisel;
center the motor so that the disk is positioned strictly vertically;
cut a circle from sandpaper proportional to the disk;
coat the circle with wood glue and spread it evenly over the surface of the board;
glue the sandpaper (to speed up the process, you can apply a heated iron to the sandpaper);
leave everything under pressure for a while (it is enough to tightly fix the board with a vice on the circle);
screw the wooden stop (tabletop);
Make sure the sanding surface is even, using a building level.

All! All that remains is to launch the homemade machine and test it in action. It perfectly polishes any wooden products - from boards to finished toys. You can also use the “grinding machine” as a sharpener.

Changing worn out sandpaper with your own hands is easy. It is enough to tear off the old one, remove the remaining glue from the disk and stick on the new one. Any grit of sandpaper is selected - the most suitable for the job.
