EDAX and talysurf. There were four wear regimes for KRF/GCI, during the starting friction period abrasion was dominant, when the process of the formation and break of transfer layers was balanced the main wear mechanisms were adhesion and fatigue, mild melt wear was found at higher temperature. For KRF/MMC, the dominant wear mechanisms were ploughing and microcuting during the running-in, when transfer layer formed, the film-film adhesion at the interface became dominant and mild melt wear occurred also at high temperature.

对于KRF/GCI，在摩擦的起始阶段主要是二体磨粒磨损，当表面转移膜的形成与破坏形成动态平衡时，粘着磨损和疲劳磨损是主要磨损机理，摩擦表面温度较高时，产生严重的粘着磨损和轻微的熔融磨损；而KRF/MMC在跑合过程中，SiCp对较软材料的犁削、微切削是主要摩擦磨损机理，转移膜形成后，表面的膜—膜粘着则为主要摩擦磨损机理，高温下也会发生轻微的熔融。

Anterior horn and then grinding, increasing chip capacity space (for the shape of chip capacity and processing characteristics, especially with a tool to compare the Japanese brands and found that much better than those of their cutting effect, the specific part in the second straight shank cutter for a brief introduction), to avoid an increase in milling tool when rapid accumulation of the phenomenon of chip.

然后修磨前角，增大容屑槽空间(针对容屑槽形状以及加工特性，特地与某日本品牌刀具作比较，发现远远优于其切削效果，具体在第二部分直柄立铣刀作简单介绍)，避免在加大走刀量快速铣削时出现切屑堆积现象。
