在加工中心使用过程中常常会遇到一些箱体内腔端面加工的问题 ,如图 1所示零件。当加工内档尺寸 5 8.5ｍｍ时 ,通常用普通镗床单刃刀刮削内端面的方法 ,不仅操作困难 ,而且效率很低。使用图 2所示的专用刀具不仅能满足加工中心的要求 ,而且生产效率提高 10倍以上。图 1　箱体该 In the process of using the center often encounter some cavity lumen processing problems, as shown in Figure 1 parts. When processing the internal size of 5 8.5mm, usually with a common boring machine single-edged knife scraping the inner end of the face, not only difficult to operate, but also inefficient. Using the dedicated tool shown in Figure 2 can not only meet the requirements of the machining center, and production efficiency increased by 10 times. Figure 1 box of the
