Product Description
Machine structure and functions
The machine, gear grinder with worm wheel, is similar with the hobbing machine in operating principle. This model is based on the characteristics of high efficiency and precision, and is widely used for grinding medium and small module cylindrical gear.
The working accuracy of spur gear reaches grade 4, and bevel wheel reaches grade 5 of National Gear Standard when the workpiece collet be firmly clamped. A closed loop with phase-lock synchro servo system is adopted in the main transmission chain, which is with high transmit accuracy, and segment gear grinding is possible. Of course, gear-slotting cutter and gear shaving cutter grinding are also available on this machine.
1) The machine is controlled by 4-axes: Closed-loop with phase-lock synchro servo system for main wheel spindle (B-axes) and workpiece, wheel radial infeed axis (X-axis), wheel tangent infeed axis (Y-axis)
2) Tooth-exchange hang-wheel (electrical hang-wheel) is replaced by digital encoder.
3) The wheel radial infeed axis (X-axis) works together with the modeling device, and profile grinding in tooth direction is realized automatically. The profiling dimension can be observed via the nixie tube on the operating panel.
4) Imported high precision roll bearings are used in the main wheel spindle.
5) Stepless speed regulation is available in wheel spindle.
6)A diamond roller is used for wheel dressing. The dresser is mounted on the machine. It is convenient to exchange grinding to dressing, and the efficiency is improved.
7) The dressing roller will aim at the tooth space automatically when grinding changes to dressing, and need not readjust.
8) Hydraulic components are collected in a individual oil tank which with temperature-control unit.
9) Static oil-mist absorber device is equipped for environmental protection.
