Grinding with the machine

There are many types of grinding machines. They are used, of course, because with a machine you can remove material more aggressively. But: there is one thing you have to pay attention to in any case: The steel must not be overheated. If your iron turns blue, it is soft (at least at this point) and unusable. You will then have to grind away at least all the blue spots. That is, once you lose patience, it becomes even more of a test of patience! I have not encountered this problem with slow runners. A second question is important here: how to put / hold the iron for sharpening? I would not recommend completely dispensing with a corresponding device. A simple adjustable tool rest is sufficient for many.

The tool support

If you want to be more precise, please take a look at Tormek 's offer, for example (I don't earn anything from naming it). They have a whole range of devices for the most diverse grinding tasks. You can also use them for other machines.

The disadvantage of the special fixtures is that you then have to take the angles as they are set. Personally, I sometimes doubt whether the precision of the fixtures is sufficient. I need to clarify that in more detail. A simple manual correction as with the simple tool rest is then no longer possible. And do not forget the Dressing of the disc (if possible)!

How to adjust the right angle?

There is a risk of ruining your cutting edge the very first time you switch on the machine. Therefore, I would recommend turning the disc by hand first (if possible) after the first lay-up to check whether material is really being removed in the right place.
