Using the slip gear and exchange teeth of the feed gearbox, a variety of metric and inch threads can be processed. According to user needs, a certain range of modules and diametral pitches can also be turned through the calculation of the slip gear and exchange gear of the feed box. Thread. Because the main shaft can be reversed, after one thread is cut, it can be quickly retracted, and then cut a second time without changing the position of the thread. When using a bar with a diameter of less than 36mm, it can extend into the inner hole of the spindle for turning processing. When turning a medium-length workpiece, use a live thimble when using a tailstock thimble.
Generally, when a CNC lathe encounters a failure, a certain degree of disassembly and maintenance work may be required on the lathe.
