Product Description
Features of the machine tool performance and structure
1. The hydraulic drive system uses screw pump which is of smooth running and low noise.
2. The wheel head adopts a structure of sleeve type bearing bush hydrodynamic bearing mainshafting and features high rotary precision and high rigidity.
3. The feeding guideway uses antifriction & plastic-filming guideway, thus promoting the smoothness and vibration resistance of low-speed operations.
4. With high machining precision, the integral layout of machine tool is rational,
Appearance is attractive, operating handles are centralized arranged and visualization, thus to make the machine easy to control and safe to operate.
5. MB (semi-automatic) grinding machinescan perform plunge-cut grinding or longitudinal grinding to conduct small-lot or batch production under the control of fixed distance or automatic measuring device.
6. For the MB (semi-automatic) grinding machines, their grinding functions and action sequences of processing cycle are controlled by programmable logic controller (PLC).
