Finished parts

【Main use】

This machine is designed to grind various cylindrical worms, such as straight sided normal worm (ZN-worm), straight sided axial worm (ZA-worm), involute helicoid worm (ZI-worm). It also can grind trapezoidal screws, suitable for machine tool works and factories to manufacture indexing worms and power transmission worms。

【NC system configuration】

【Working accuracy】

working accuracy

when thread start=1-2                            Grade 5(GB)

when thread start≥3                             Grade 6

when grinding ACME screw within 6mm pitch        Grade 6(GB)

【Technical characteristics】

1、High precision screw-and-nut and gear pairs are used to achieve high pitch accuracy。

2、Automatic indexing mechanism can easily grind single or multiple-start worms in high precision and reliability。

3、Wheel dressing is done with a hydraulic automatic wheel dresser, through profile modeling, to dress grinding wheel into ZA, ZN and ZI profiles。

4、Grinding wheel spindle employs film-feedback hydrostatic bearings to get high productivity and fine finish of the workpieces。

5、Work spindle and table are driven by AC Servo motors。

6、A full-closed cover and an imported oil-mist extractor are provided with the machine to improve working environment。

7、If a CNC wheel dresser adopted, the machine can realize ZA, ZI, ZN, ZK and ZC1 worm grinding。
