Main characteristics of this machine tools
★ This machine tools can grind internal circular hole and tapered hole below Φ50mm.
★ The machine tools body is casted by cast iron with compact structure, good stability and strong rigidity.
★ Setting and adjustment of machine tools parameters adopt touch screen. Human-machine dialogue can be realized.The operation is intuitive andconvenient.
★ Machine tools feed adopts Japanese Mitsubishi servo motor to drive ball screws to move through coupling. The guide rail adopts criss-cross steelrolling rail which is of high accuracy and good rigidity.
★ The hydraulic section for reciprocating motion of work table is automatically controlled by touch screen through PLC.
★ As for clamping of machine tools work piece, several fixtures are available for user to select such as three-jaw chuck, pneumatic fixture, hydraulic fixture and diaphragm fixture.
★ Grinding wheel spindle for grinding adopts high-speed motorized spindle and is controlled by static frequency converter, so as to realize stepless adjustment.
