Use Shenyang CK6136 with 980TDc to process M16 thread, the length is 60mm, and it needs to be turned out without tailstock.

 

solution

The thread is divided into three sections for processing, and the G32 command is used to ensure that the position of the thread cutter (lower cutter) of each section is on the thread path. Because the thread segmentation processing includes cutting in and cutting out, it is completed with three G32 instructions: cutting in + cutting thread + cutting out three parts to process the thread in sections;

Calculate the relationship between the axial feed and the rotation angle of the spindle and the axial movement of the tool when cutting in and out. It must be ensured that the cutting point of each knife is cut to the bottom diameter of the thread, and the angle of the cut-in and cut-out matches the rotation angle of the main shaft and the distance of the axial movement of the tool.

 

Application effect

Through the segmented processing, the top clamping process is eliminated, the center clamping deformation is prevented, the cutting efficiency is greatly increased, and the labor cost is reduced.
