Circular subdivision method: This method uses the spindle encoder on the HG52 precision machine tool to cut the thread of the starting point pulse. During the process of cutting, different angles are used for cutting. The encoder has a 360 ° rotation and is fed in three lines, which means it starts feeding when it rotates 120 °.

This method is relatively simple and has no limitations in application, but it also has corresponding shortcomings, such as some CNC systems not supporting it, making it difficult to use.

Axial line splitting method: This method is the same as the small skateboard line splitting used for processing multi line threads in Horizontal lathe. As long as the coordinates of the starting point are changed, it can be used.

Simply put, during the processing of the second helix, there is a difference in pitch in the direction of the starting point of the first helix. In the specific programming process, the tool is moved in the Z direction, similar to the process of machining other spiral lines.

This method is relatively easy to use in the process of using Precision machine tool, not limited by numerical control systems, can perform multi line thread machining, and can use cyclic instructions to reduce programming workload.
