Advantages and features of machine tool

The machine tool adopts hydraulic transmission, able to achieve smooth work. It is equipped with step-less speed regulation and overload safety devices, able to achieve such functions as automatic cycle, section-based cycle, and separate inching adjustment. The machine tool has its safety ensured by means of electrical and mechanical devices. All operations are completed on the main button station, so its operation is fairly easy, safe and reliable.
