Overview
QK1319B CNC coupling boring lathe has a monolithic and flat structure. The front end of the machine tool spindle uses domestic hydraulic chucks. The spindle bearings are ZWZ, HRB, NSK and other domestic famous brands and imported brands. Tool holder, spindle motor adopts explosion-proof asynchronous motor or main servo motor, CNC system is Guangzhou CNC or Fanuc system, optional automatic chip removal machine is optional.
This machine tool is a special numerical control equipment used for boring of casing sleeves of petroleum oil. It can also be used as a general numerical control lathe. Chopped and other processing. Large range of application (by increasing the configuration, the maximum diameter of the processed coupling can reach φ533.4mm-20 "), high efficiency, good accuracy and stability, good uniformity of parts size, easy to operate.
