加工螺纹的车刀是成型刀,它的刀尖角ε的几何精度和安装精度直接决定着被加工工件螺纹牙型半角的精度,而螺纹中径误差受进刀尺寸和牙型半角误差影响。解决螺纹车刀的刃磨和安装的传统方法是:(1)利用对刀显微镜刃磨和安装;(2)利用对刀板刃磨和安装;(3)利用螺纹样柱刃磨和安装;(4)利用对刀柱刃磨和安装;(5)利用搬小刀架靠平面安装。这些方法都存
Machining a thread turning tool is a forming tool whose geometric accuracy and installation precision of the tool nose angle ε directly determine the accuracy of the half angle of the thread shape of the workpiece to be machined while the error of the thread diameter is affected by the size of the tool entering and the half angle error of the thread form. The traditional methods for sharpening and installing a thread turning tool are: (1) sharpening and mounting using a knife-facing microscope; (2) sharpening and mounting using a counter blade; (3) sharpening and installing with a thread- (4) the use of knife sharpening and installation; (5) the use of moving knife holder by plane mounting. These methods are saved
