A tapping machine is usually composed of a motor, a control system, a feed mechanism, a spindle and a chuck, etc., and the operator only needs to fix the workpiece to be processed on the workbench and set parameters such as rotation speed and feed rate to carry out automatic or semi-automatic tapping operations. Modern tapping machines can achieve high-speed operation of hundreds of revolutions per minute, and the feed accuracy can reach 0.01 mm, which improves the processing efficiency and accuracy.
