加工有深长槽的零件时,由于腰槽的深度超过了带柄铣刀的工作部分,会发生振动或断刀现象。主要原因是带柄铣刀刚性不足。因此,加工深长腰槽时均沿用“接刀”的办法进行铣削。这种方法效率低、质量差。现介绍一种用加强带柄铣刀的刚性来铣削深长腰槽,方法如下: 1.在立式铣床(见图)的升降立柱的导轨面上,装一个带有顶针的固定架; When machining parts with deep grooves, vibration or breakage may occur due to the depth of the grooves exceeding the working part of the milled cutter. The main reason is the lack of rigidity with a handle cutter. Therefore, the processing of deep groove are used along with the “knife” approach to milling. This method is inefficient and of poor quality. Now introduce a way to strengthen the rigidity with a shank cutter to mill deep groove, as follows: 1 in the vertical milling machine (see Figure) lifting column rail surface, equipped with a thimble holder;
