When choosing a suitable grinder, you should pay attention to some important nuances. If you are looking for an electric model, the power level must be considered. For home use, the simplest samples with low power are suitable.

Pay attention to the dimensions. For home use, it is better to select the most compact copies so that they do not take up too much space.

The functionality of the equipment is important. Professionals often select models for themselves that are capable of sharpening products, as well as polishing and sharpening. In addition, for permanent use, it is better to select models with a cleaning system and a water cooling system.

Now we will analyze in detail how to properly sharpen cutting tools with such equipment. It is important to fix the product correctly in the machine holder. Otherwise, the sharpening will be skewed.

Holding the blade firmly, tighten the special clamping screws until they stop. To control the sharpening angle, you should use a marker, with it you mark the chamfer of the product to be machined.

If you have a stationary device, then proceed to adjust the table. Most often, the units are equipped with special fasteners that allow you to securely fix the equipment on flat surfaces.

During operation, the holder moves in the direction from right to left, while all movements are performed relative to the grinding stone. The cutting tool must not be allowed to protrude over the edge. It is recommended to immediately fix the holder 10-12 mm from the edge of the working area.

If sharpening is in progress, it is best to supply water cooling to avoid overheating and malfunction. During processing, make sure that the abrasive surface remains clean, as it can get greasy rather quickly.

To clean the abrasive, a special block is used. Cleaning should be done regularly. After sharpening, fine-tuning is most often performed. For this, a special paste is taken. Further polishing is done. After it, burrs and other defects should not remain on the cutting tool.
