(3) After sharpening, erect the milling cutter on the platform. If the shaft is vertical, all the blade tops can be level, and the deflection angle of the blades can be symmetrically centered vertically, thus meeting the requirements.
This can also be modified by using a 90 degree square on the flat plate to see if there is a gap between the end mill and the square. Usually the two taller feet are observed first (both feet touching the bottom first). If the foot is not vertical, grind the higher foot to the same height (vertical) as the other foot. At this point, if there is a step difference between the two feet and the other two opposite feet, the end mill will swing. At this point, grind the two higher feet down at the same time. In the same way, turn the milling cutter 90 degrees and observe the flatness of the other two pairs of feet. Finally, the four pairs of feet touch the bottom in addition, and the milling cutter is vertical. The milling cutter after sharpening.
In manual grinding, the level and various angles of the blade are not easy to master, in training to be different from everyone, just pay attention to the grinding relief angle slightly smaller. When the top blade is not normal, as long as the top can be the highest, and if not the cavity cleaning angle, you can also grind more than 0.2 mm on the tip to increase the tip strength.
4. Grinding technology of the main edge (ie side edge) of the end mill.
If the main edge of the end mill is worn, it must be ground along the helical line on the grinding wheel (the diameter of the grinding wheel is as small as possible) (it is difficult for beginners to grind well). However, after grinding, there is generally a taper, and the smaller the taper, the higher the level of operation.
