By changing the combination of the inserts constituting the insert portion 3, the groove width and each shape of the T-groove to be cut into the work can be easily adjusted. Moreover, in each fitting surface of the inserts 4 and 5, the convex part and the concave part of the fitting surface of the insert 4 overlap with the concave part and the convex part of the fitting surface of the insert 5. Therefore, since the inserts 4 and 5 partially overlap each other in the thickness direction, the protruding length of the insert portion 3 can be shortened.

一种刀盘系统，包括刀柄和刀盘，刀盘与所述刀柄连接，包括：两个凹槽，对称分布在所述刀盘的上表面中部和下表面中部；螺纹孔，连通所述两个凹槽，且，直径小于两凹槽的直径；锁紧螺母，用于固定所述刀柄和刀盘；其中，所述螺纹柱容纳在所述凹槽中，且，与所述螺纹孔丝接，所述锁紧螺母旋拧在所述螺纹柱的末端，且，顶在其中一个凹槽的底部。刀盘的上下凹槽对称设置，且在刀盘的各角设置了四个刀槽，该结构使刀盘可以双面安装，提高刀盘自身的利用率；在调动平衡螺孔中可以设置调动平衡螺丝，确保工作时，刀盘在高速旋转的情况下依然能够保持平衡；刀盘整体为扁平长方形，在不减小刀片线速度的情况下，还避免了刀库上相邻刀柄被干涉的问题。

一种伸缩式球刀铣刀

本发明公开了一种伸缩式球刀铣刀，包括一级铣刀、二级铣刀、三级铣刀、一级切削刃、二级切削刃、三级切削刃、大滑动槽、一级切削口、二级切削口、三级切削口、小滑动槽、小挂台和大挂台。本发明的有益效果是：该伸缩式球刀铣刀设计合理，一级铣刀、二级铣刀与三级铣刀之间呈滑动连接配合组成可伸缩铣刀，采用滑动配合的连接方式可以将铣刀装夹在夹头上由夹头内部的顶杆自上而下的顶出调整，小滑动槽底部距离二级切削口的高度为10mm,由于二级铣刀内部为空心的小滑动槽，为了保证二级铣刀的切削强度，所以设置高度为10mm的距离，小滑动槽上半部分直径大小与小挂台直径一致，下半部分的直径与一级铣刀的夹头直径大小一致。
