1) Basic principles

2) Factors that improve the quality of inner hole processing from the perspective of tool application

Selection of tool main declination angle: When selecting the main declination angle, it is recommended to choose a main declination angle as close as possible to 90 degree , and not less than 75 degree . Otherwise, the radial cutting force will increase sharply.

3) Effective discharge of chips

4) Selection of tool clamping method

The overall support is better than the tool bar directly clamped by screws. It is more suitable to clamp the tool bar on the V-shaped block with screws. However, it is not recommended to use screws to directly clamp the cylindrical handle tool bar because the screw will be damaged if it acts directly on the tool bar. Toolbar.

5) Use a special tool bar to reduce vibration and increase the effective removal of iron chips

Anti-seismic tool holder: This type of tool holder generally has an anti-seismic unit inside the tool holder, which can effectively reduce vibration caused by excessive overhang. However, this kind of anti-seismic means starting from cutting tools is often expensive and has harsh application scenarios.
