Based on the patent ZL 201510030023 .1 "A new type of grinding wheel for grinding rubber rollers and its manufacturing method and technology", the mechanism of pores action in the new type of grinding wheel is discussed . Compared with the traditional grinding wheel , the new grinding wheel has good processing ability when it grinding the rubber rollers , and it is not easy to cause pore blockage , no chatter and scratch marks , which is conclusive to improving the processing quality and improving the labor efficiency . Through the test sample grinding application feedback , the prorosity of the new grinding wheel reaches to 70% ~80% , the revolving velocity is 120 m/s , which is 16% and 20% higher than that of the general large pore silicon carbide wheel respectively . The surface roughness of the workpiece is increased in away , and the repair periods is prolonged for more than 2 months . Targeted selection of corundum hollow spheres can produce new grinding wheels that conform to the design and effectively avoid some problems of traditional grinding rubber roller wheels , such as black heart of silicon carbide wheel with large pores , low working strength , and additives that are unfriendly to the environment . At the same time , the production process of the new type of grinding wheel is stable and reliable , and it is easy to be popularized and applied .%在专利Z L 201510030023.1《一种新型磨胶辊砂轮及其制备方法》的基础上,对新型磨胶辊砂轮中的气孔作用机理进行理论探讨.新型磨胶辊砂轮与传统的磨胶辊砂轮相比,不易发生气孔堵塞问题,具有良好的工件加工能力,在磨削工件时不会产生振纹和划伤痕迹,有利于提升工件的加工品质、提高劳动效率.通过试验样品磨削应用反馈:该新型磨胶辊砂轮气孔率达到70%~80%,比一般大气孔碳化硅砂轮高16%以上;回转破裂速度达到120 m/s,比一般大气孔碳化硅砂轮强度提高20%以上;磨削后工件表面光洁度有所提高,修复周期延长2个月以上.并且,通过针对性地选择刚玉空心球粒度,能够制造出具有设计的性能的砂轮,能有效地避免传统磨胶辊多孔磨具的一些问题,比如大气孔碳化硅砂轮常见的烧成黑心、使用强度偏低、成孔剂不环保等问题,同时该新型磨胶辊砂轮的生产工艺性能稳定可靠,易于推广应用.
