本厂根据各种机床布局对刀架结构的不同要求,所设计的燕尾导轨在组合形式上不尽一样,使燕尾导轨在截面上的结合面呈多种特点。长期以来,这些不同的燕尾导轨的加工就存在一个测量手段问题。其中有一部分燕尾导轨的燕尾宽度尺寸可用普通游标卡尺配以圆棒的方法进行测量,但是有大部分的导轨在加工中燕尾的宽度尺寸是不适合采用上述方法检测(燕尾的各种形式见附表)。
The factory according to the different layout of the machine tool holder structure of the different requirements of the design of the dovetail rail in the form of different combinations, the dovetail rail in the cross section of the surface was a variety of features. For a long time, there has been a measurement problem with the machining of these different dovetail guides. The width of dovetail of some dovetail guides can be measured by the ordinary vernier caliper combined with the round bar, but most of the width of the dovetail in processing is not suitable for the inspection by the above method (various forms of dovetails are shown in the attached table ).
