在保证30公尺/秒的切削速度下磨制小孔,可获得良好的磨削质量与合理的生产率;因此磨10公厘孔的砂轮轴转速约为60000转/分。过去由于设备条件所限,对10公厘以下的孔均用研磨来解决,这就影响了生产率。1957年,苏联专家拉基维林设计了一种100000转/分的风动内圆磨具。经过多次试验与改进,目前已初步获得成功。现将该磨具情况作一简单介绍,以供大家参考。 Grinding of the holes at a guaranteed cutting speed of 30 m / sec gives good grinding quality and reasonable productivity; therefore, the grinding spindle speed of 10 mm holes is approximately 60,000 rpm. In the past due to equipment constraints, the hole below 10 mm grinding to solve, which affected the productivity. In 1957, Soviet expert Rakivirin designed a 100000 RPM pneumatic internal circular grinding tool. After many tests and improvements, it has initially achieved success. Now the abrasive situation for a brief introduction, for your reference.
