• CNC Semiautomatic Hob-Grinding Machine VZ-722F4

CNC Semiautomatic Hob-Grinding Machine VZ-722F4 used for grinding along front surface area of the grinding wheel with cooling a single-thread, multiple thread of the shank and arbor-type hobs, also with closed-type chip grooves. The machine presented in a horizontal arrangement of the welded frame in gray cast iron. The optimum form of the frame and the extra ribs give high rigidity. Manufacture of basic parts made of cast iron adds nodes to high rates of vibration. The base of the machine serves as a frame on which are mounted the necessary Assembly units of the machine. Special device SINUMERIK 840D CNC device ensures the quality and proper operation. With the powerful system diagnostics, the system displays the parameters required by the operator to monitor the state of the drive and grinding parts. In addition, the standard software of CNC system mounted the original system of preparation of control programs. The system automatically generates a control program for processing of wheel dressing and hob.
