Disc dominant wear the main parts in the knife surface, manual gear only commonly behind when grinding. Can use disc directly gear wheel. Method is armed with milling cutters, cutter teeth behind in the grinding wheel grinding directly to basically eliminate the worn parts so far, and then continue to grind in turn all cutter tooth. The key is to stand firm and take firm, keep the tooth grinding must agree. May, when necessary, use grinder stents to keep cutting tool position. In the demand is not high, manual gear because of the milling cutter each blade no consistency, but for cutting. For side cutting edge also can consult this method, but can use the side of the grinding wheel to grind.

Refers to the dominant wear type is mainly behind with spiral blade wear. Vertical milling manual gear often make side after the blade is not straight, with the side of the blade surface processing schemes. But manual gear economy is convenient, can do rough machining tool, or end with processing. When the gang right hand grip, left hand refers to light withstand blade part, make the light on the back edge of the disc surface grinding wheel with the round on the horns of the blade and grinding wheel handing over the region and tangent, make blade posted in the grinding wheel behind, gently rotating blade handle the gang behind, observe the width of blade with blade, a 0.2 ~ 0.3 mm is more appropriate. Grinding out in other blade.

For the keyway milling cutters, manual gear can ensure tool use performance. Because of the depth of the milling cutter keyway keyway limited, so tool wear focused on the edge of the head. Tool wear directly influence the processing of the keyway width. When the gang can directly grinding milling cutter short, for wear all wear off, to grind out the blade can. So the original milling cutter blade is not the damage, can guarantee the machining quality. The whole process of cutting in disc on the grinding wheel to finish.
