Application of Norton® WGE Worm Grinding Wheel on Gear Grinding

As an important part of automobile gear grinding, worm grinding requires the grinding wheel to have good cutting performance and shape retention. At the same time, it is necessary to avoid surface defects such as burns and vibration lines under the condition of satisfying the accuracy of gear tooth surface.
Norton® introduces the new WGP and WGE wheels for worm grinding. Compared with the traditional formula, the new grinding wheel improves the permeability and mechanical strength, which improves the tooth surface accuracy of the grinding workpiece, and enhances the chip removal and cooling capacity during grinding of the grinding wheel, greatly reducing the risk of burns. Background Introduction A customer mainly supplies the gear components of the passenger car transmission for the automobile enterprise, mainly based on small modulus. With the development of the business, the company has put forward higher requirements on the processing efficiency of the gears and the quality of the workpiece after grinding, and hopes to reduce the comprehensive production cost. Through a detailed understanding of the customer's field application, our engineers decided to use WGE's high-performance worm grinding wheel to replace the customer's original matching brand of grinding wheel.
Application introduction test date: 2016.08
Grinding application: worm grinding test machine: Reischauer RZ260
Competitor: an imported brand grinding wheel
Test Results:
1. With the same efficiency and longevity, the machine's power consumption is reduced by 18% using the Norton® WGE worm grinding wheel. The power used by the machine often determines its life. WGE grinding wheel can better ensure the use of machinery and equipment under the same efficiency, which helps to extend the service life of the spindle and screw and reduce the equipment cost.
2. Compared with the tooth profile after grinding of an imported brand grinding wheel, the gears after grinding by Norton® WGE grinding wheel perform better on the tooth surface drum shape and amplitude. Improving the tooth-tooth direction is to improve the accuracy of the gears inter-engaging, which can reduce the noise generated by the gears at high speed and reduce the feeling of frustration.
