This machine tool is designed and manufactured for thread processing of oil pipe, drill pipe and casing in petroleum, chemical and metallurgical industries. It can turn all kinds of internal and external threads (metric, inch and taper pipe threads) accurately through the automatic control of CNC system. It is especially suitable for thread processing with mass production. This machine can also process rotary parts. For example, rough and finish machining of internal and external cylindrical surfaces, conical surfaces, circular surfaces, and medium and small batches of shaft and disk parts. It has the characteristics of high automation, simple programming and high machining accuracy.
The machine tool has two linkage control axes, semi closed loop control. The Z-axis and X-axis use ball screw pairs and AC servo motors to achieve vertical and horizontal movement, with good positioning accuracy and repeated positioning accuracy.
