Finished parts

【Main use】

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】

1、SIEMENS 828D system, controlling 5 NC axes。

2、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 start3, 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
