Many craftsmen set the circle on the "grinder" on the wrong side. I tell you what it can lead to, and how to do it right

Any work begins with the correct preparation of the instrument. And in the end, the final result may depend on how you do it. Today I want to share a few "secrets" for preparing a "grinder" for work.

It would seem that this can be difficult: put on a grinding or cut-off wheel, tighten the nut, and you're done. But here's what I noticed. Many, even experienced craftsmen, put the circle on the grinder on the wrong side. And this can lead to the beating of the circle and its biting.

How to understand which side the circle is installed on the grinder

First, look at the circle that you will be setting. On one side there is a drawing. And on the same side, in the middle, you will see an iron washer. This side of the circle is called the base side. The other side never has such a washer. All circles are done in this way.

Now we look at the "grinder", on the plane where the circle is installed. A gearbox is visible in the middle of it, and around it we will see an iron flange washer. The washer has metal tabs. They are made for better grip.

We set the circle correctly - we work well and safely

Now that we have studied the surfaces of the circle and "grinder", it remains to correctly assemble and fix the circle. That's right - this is the pattern inward. Then the metal washer of the circle will lie on the flange washer of the "grinder". The lugs on the grinder's washer will fit snugly into the circle and provide extra grip. This will help avoid twisting the circle when biting into it.

Also, with the correct installation of the circle - with the pattern inward - we will now grind the surface or sharpen the drill with the side without paint. Agree, it's more convenient, the paint on the wheel will not interfere with your work.

Now all that remains is to secure the circle with a nut. Here, too, there is a "trick" - do not overtighten the nut, otherwise then you will be tortured to unscrew it. Therefore, many craftsmen are used to tightening the nut by hand, without using a wrench.

And one more subtlety. Grinding wheels can have an uneven surface - this sometimes happens when wheels are cast in the factory. Manufacturers have foreseen such a possibility on all grinders, they made a small backlash on the thread of the clamping nut. When clamped, such a nut smooths out possible unevenness on the surface of the circle. It fits tightly and without distortion.

I hope my advice will help you work more efficiently and happily.
