过去,用万能胶将砂轮粘在砂轮杆上进行小孔磨削时,由于难以注入冷却液,冷却条件差,因此容易产生热和压力,使砂轮与杆脱开。这样不仅影响效率,质量也难保证。针对上述情况,我们在实践中反复试验、不断总结,终于搞成了图示磨削小孔的砂轮简易安装法。 In the past, when gluing a grindstone to a grindstone stem by using a universal adhesive, it was difficult to inject the coolant because of poor cooling conditions, so heat and pressure were easily generated and the grindstone and the stem were separated. This will not only affect the efficiency, quality is difficult to guarantee. In view of the above situation, we repeatedly test in practice, continue to summarize, and finally became the icon grinding wheel simple installation method.
