How to see lathe pitch table?

No matter what kind of lathe, the horizontal and vertical of the thread table and the tool table are aligned with the position of the handle, and include the number of teeth matching position of the two pairs of hanging wheels. You just need to find the number of positions of the machined thread pitch, and then find the corresponding positions in the transverse and longitudinal response of the handle, and move the handle to the specified position as required. When processing, you can first test a knife to measure whether the pitch is correct, if not correct, re-check the position of each handle
