The spindle of CNC horizontal lathe adopts manual control, mechatronics design, beautiful appearance, reasonable structure, wide use and convenient operation. The machine tool can realize automatic control and can turn and process the inner and outer circles, end faces, grooves, and arbitrary tapers of various parts. Processes such as surface, spherical, metric and inch threads, and tapered threads are suitable for mass production. The CNC system can be equipped with a standard RS232 interface, so the machine tool can enter the DNC system. CNC horizontal lathe bed guide rail adopts super audio frequency quenching, technology, strong wear resistance, high precision, advanced spindle system structure, stable speed, and high cutting performance. Longitudinal and horizontal use ball screw drive. Excellent dynamic response and low noise. The CNC horizontal lathe is suitable for training in mechanical colleges and secondary professional schools, and can provide various programming operation training and actual processing training for students.
