Product Details

Applications:    


△ QK-series CNC oil country lathes are mainly designed to process all kinds of internal and external pipe threads including metric, inch, module, DP and taper threads, as well as having all the common functions of normal CNC lathe such as processing the inner bore and end face of shafts and disks. CNC oil country lathes are  widely used in industries including petroleum exploiting, coal and minerals mining, chemical piping and geological prospecting, it is high-efficiency equipment in processing and repairing drilling pipe, drilling rod, thread coupling and so on.
