Cylindrical grinding machine SK7732×20

workpieceCNC5-axis

This machine is used to grind various cylindrical worms (ZA, ZN, ZI, ZK, ZC1), and also can be used to grind trapezoidal screws。 【NC system configuration】 No. of programmable axes:five Axis Z: table lognitudinal traverse (With grating scale) full close-looped Axis X: Wheelhead cross feed (With grating scale) full close-looped Axis C: Rotation of work spindle (With angular encoder) full close-looped Axis V: Vertical feed of dresser slider Axis W: Horizontal feed of dresser slider 【Working accuracy】 Cylindrical worms: when thread start=1-2, the accuracy is superior to grade 5；when thread start≥3, the accuracy is grade 6。 Trapezoidal screws: The accuracy is grade 6。 【Technical characteristics】 1、Wheel dressing is made by 2 diamond discs moving simultaneously 2、The wheel spindle is driven by an AC servo motor, and the speed can be regulated steplessly。 3、The adjustment of helix angle is done and locked manually 4、An AC servo motor directly powers the two diamond discs, ensuring a constant speed and low vibration。 5、A dynamic balancing system is available as optional accessory if required by the user 6、A full-closed housing and an oil-mist extractor are provided with the machine to purify working environment
