Abstract

Abstract

By comparing machine power, grinding temperature, tool surface roughness and the quality of the cutting tool edge, the influence of grinding wheel stiffness on grinding performance and quality of cutting tools was analyzed.It has been proved that, in a certain extent, the reduction of grinding wheel rigidity could improve grinding performance and quality of the tool.In addition, the rigidity improvement of grinding wheel is obvious when adding 10vol% nylon, the average grinding temperature of which is 50℃lower than that of common grinding wheel under the same grinding conditions.After grinding the same number of workpieces, the machining power of low rigidity grinding wheel is 30% to 50%that of the ordinary wheel.It is found that tool surface roughness value Racan reach lower than 0.02μm after grinding with uniform ground surface.At a microscope of 500 times, no collapse edge defect can be seen, which means that the blade qualityis improved significantly.
- rigidity,
- machine power,
- grinding temperature,
- surface roughness,
