Drilling holes of all steel knife and inlay knife
- Aug 20, 2018 -

All steel machine knife:

Will make the holes first, then in heat treatment, so the hole distance will change a little bit and hard to control.

While, for inlay machine knife:

Heat treatment is the before drilling the holes, therefore, tolerance of hole distance is easier to control.

That's the reason why sometimes for the same long knife, we can control the hole distance tolerance of inlay machine knife, but cannot for all steel machine knife. But we will learn to improve it.
