  • Features
  • Specification
  • CONFIGURATION

1. Adopts Siemens 7 inch LCD-TFT colorful touch screen, built in program of engineer's genius designation to make the operation very simple and convenient for the users.

2. Adopts hydrostatic bearing for the spindle to get high rigidity, together with 18.5kw motor to provide strong power, apply to the heavy duty machining. Spindle rotation is supported by rigidity oil film, no wear, ensure the long time precision and life.

3.High rigidity rectangular guideway is designed on vertical motion, and coat with TURCITE-B belt, to get low fricion coefficien.

4. AC motor drives on cross and vertical motion. MPG replace the tradition mechanical hand wheel, which can realize higher accuracy and easy operation.

5. Independent, large capacity integrated hydraulic tank, standard equipped with air cooling and pressurizer, isolate heat and vibroseis, to provide excellent power for precision grinding.
