通常在万能铣床上固定端铣刀均采用带有螺钉的过渡轴套或“莫奇塔”型的卡盘(ΓOCT21054～75)。前一种固定方法会加大铣工的劳动量,而后一种固定方法则可靠性差。现在所介绍的卡盘(见图),具有通用性,无需加杆固定,只需使用锥形柄(莫尔斯锥度5;4;2)和圆柱形柄(直径4-16mm)固定即可。同时也适于利用刀架(直径为27、32、40、55mm)和安全滑块在铣床上固定端铣刀。铣床主轴的锥度为7:24。用圆 Usually in the universal milling machine end mills are used with a transition sleeve with screws or “Mocita” type chuck (ΓOCT21054 ~ 75). The former method of fixing will increase the amount of labor for milling, and the latter method of fixing is less reliable. The chuck now shown (see picture) has the versatility of being able to be fixed without the need of a bar, simply by using a taper shank (5; 4; 2) and a cylindrical shank (4-16mm in diameter) . It is also suitable for fixing end mills on milling machines with tool holders (diameter 27, 32, 40, 55 mm) and safety slides. The taper of the milling spindle is 7:24. With a circle
