CNC pipe threading lathe, oil field & hollow spindle lathe QK1327-1363 series

Short Description:

QK1327 and QK1363 series machine tools are horizontal flat bed CNC hollow spindle lathes with semi closed loop control. Two linkage control axes, Z-axis and X-axis use ball screw pairs and AC servo motors to achieve longitudinal and lateral movement, with good positioning accuracy and repeated positioning accuracy.

This machine tool is designed and manufactured for thread processing of all kinds of pipes 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. This machine tool can also process rotary parts as a normal conventional lathe. 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.

Features

*Big spindle bore and double chuck allows clamp and process big diameter pipes.
*Integral machine bed adopts high strength iron casting to realize high rigidity and precision.
*Ultrasonic frequecncy quenched guide ways are hard enough for good wear-resistance.
*Equipped with taper guide bar device, this enables the machine to process taper threads.
