When sharpening the cutters, the blade is ground along one of the surfaces – back or front.
When sharpening the cutters, the blade is ground along one of the surfaces – the back or front.
A milling cutter with a curved back surface assumes sharpening of the front part, whereas a rectilinear surface leaves more freedom – in this case, sharpening on any of the surfaces is allowed.
If we are talking about profile cutters, then in most cases sharpening along the front surface is chosen in relation to them.
The only exception here is special cutters with a very thin blade.
Standard processing options can seriously damage the integrity and effectiveness of such a blade.
In the case when you have to work with grooved or prefabricated cylindrical cutters, the best option for sharpening is to work with a flat back surface.
One of the main requirements for safe sharpening of a milling cutter is the correct installation of the sharpened surface to the grinding wheel.
This is especially true when the front surface is being sharpened – the front angle must be constant.
The axis of the milling cutter is installed parallel to the grinding wheel with some displacement.
The work on sharpening the end blade assumes that the grinding wheel and the back surface should be located parallel to each other.
During operation, the grinding wheel seems to "run over" the edge.
If the milling cutter is prefabricated, its knives can be sharpened directly in the body itself, or outside it.
Sharpening is in many ways similar to that when working with solid cutters.
It should be borne in mind that after sharpening the cutter, quality control of the work should be carried out.
For example, you should check the rounding of the edge, for which it is enough to compare the sharpened cutter with the original copy.
In addition, there are surface roughness requirements that must also be met.
