STC CNC pipe threading lathe capable of increasing rigidity for 2.5 times
The pipe-machining series of CNC lathes is developed by absorbing the advanced technology of foreign like products based on the years of experience in pipe-machining lathe of the company. It is the special CNC lathe for machining various pipes and pipe threads in oil drilling and metallurgical industries. It is featured with large pore diameter, high efficiency and strong rigidity, while the machining precision of the machine tool can reach IT7, and surface roughness of the work piece can reach Ra1.6ɥm.
