hits:682 createtime:2017-08-15 10:22:26

Finished parts

【Main use】

The machine is mainly employed to grind plane & taper enveloped toroidal worm

【NC system configuration】

1、SIEMENS 840DSL CNC system, controlling 6 NC axes with 4 of them in a linkage。

2、The programmable axes are described as followers

Axis X: cross-feed of wheelhead   with grating scale   full close-looped

   Axis Y: High speed adjustment of grinding attachment    with grating scale   full close-looped

 Axis Z: Table longitudinal movement    with grating scale   full close-looped

Axis A: Adjustment of helix angle    with angular encoder    full close-looped

Axis B: Swivel of wheelhead   with angular encoder      full close-looped

Axis C: Rotation of work spindle   with angular encoder     full close-looped

The flank grinding of worm can be carried out by the synchronous movement of the axes X, Z, B & C

【Working accuracy】

Accuracy of enveloped toroidal worm can be grade 5。

【Technical characteristics】

1、Applying the principle of virtual center distance, the adjustment of center distance and base circle can be done by setting parameters。

2、The two flanks can be ground in one setting-up。

3、All adjustments are at servo axes, so rapid, precise and easy。

4、Either servo axis for turntable or adjustment of helix angle is driven directly by a torque motor, therefore, featured of precision & long life。

5、Thanks for a powerful wheel spindle with a built-in permanent-magnet motor, and a precise balancing of wheel, which featured of little vibration,  an excellent surface quality is obtained。

6、The axial position in the central plane of the toroidal worm is determined automatically with the help of an aligning probe

7、Equipped with a CNC diamond disk dresser, the wheel can be dressed precisely to any profile on our customers’ request

【Main specification parameters】

1、Max. diameter mounted 320mm
2、Max. center distance 2500mm
3、Range of major diameter of worm to be ground 30~320mm
4、Range of miner diameter 20~280mm
