hits:470 createtime:2017-08-15 10:39:56

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 6 NC axes,3 of them in a linkage。

2、No. of programmable axes:six

Axis Z: table longitudinal 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 A: helix angle adjusting

(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 up to grade 5;when thread start≥3, the accuracy is up to grade 6。

Trapezoidal screws: The accuracy is up to grade 6

【Technical characteristics】

1、Grinding wheel dressing is made by two diamond discs moving simultaneously

2、A powerful built-in permanent magnet synchronous motor (PMSM) is adopted to drive wheel spindle

3、The adjustment of helix angle is done and locked automatically, pricise and fast

4、An AC servo motor drives directly the two diamond discs, ensuing a constant speed and low vibration

5、A dynamic balancing system is provided as an optional accessory at extra cost

6、A full-closed housing and an oil-mist extractor are provided with the machine to purify working environment
