Heavy duty conjoined structure CNC lathe CN-C40E, CN-K40D
1.Monolithic conjoined structure of lathe bed,the stiffness of lathe is high,while the stable is good and vibration is small.Z direction guide rail spans 320 mm,while X direction spans 190 mm.
2.The main drive system is mechanical three gears,program automatic gear shifting,stepless speed regulation in gears.Apply to different cutting requirements.It is novel structure,unique,maintenance is simple and convenient.
3.Key purchased components of machine tool such as CNC system,spindle bearing,ball screw,etc are all used the products of the domestic and abroad well-known manufacturers,so that the machine has higher reliability.The sliding surface of the lathe rail is plastics sticking.The friction damping is low.The machine tool has a good consistency that the precision can achieve stably level IT7 —IT6,and the processing surface roughness can reach Ra1.6.
4.This heavy duty machine adopts mechanical and electrical integration design,the overall layout is reasonable,easy to operate,one can operate several machine tools at the same time.The manufacturer is responsible for training 1-2 staff free.
