How to grind the milling cutter

1. Regardless of the number of edges and mills, first straighten the edge of the blade perpendicular to the axis, which is the key to your technical skills;
2. The grinding wheel should be polished. Watch the tip of each blade as the reference. The principle of preserving the cutting edge is to repair the front and back angles, the secondary rear angle and the blade declination.
3. For the choice of angles, it is recommended that you look at the milling process books, which are described in detail;
4. When finished, find a platform and set up the milling cutter. If the axis is vertical, all the blade tips can be a bit to point, and the yaw angle of the blade is evenly centered. That is basically OK.
