我厂磨钢球砂轮经用户多年使用,认为内在质量比较好,但由于该砂轮非常硬,我厂机械加工不了,造成产品几何形状不规整,几何尺寸超过标准规定,给用户使用带来了很大困难和麻烦。如砂轮直径大,不能装卡,用户不得不请人象石匠加工石器那样,一片一片地凿成要求尺寸,造成人力、物力和财力的浪费。这种情况,用户曾多次向我厂反映,我们也曾采 I plant grinding ball used by the user for many years, that the intrinsic quality is better, but because of the wheel is very hard, I can not machine processing, resulting in irregular product geometry, geometric size exceeds the standard, to the user to bring a very Big difficulty and trouble. Such as grinding wheel diameter, can not hold cards, the user had to ask people like stonemason processing stone, one by one chisel into the required size, resulting in human, material and financial waste. This situation, the user has repeatedly to our factory to reflect, we have taken
