目前我国磨具制造厂生产的直径500～750毫米,厚度为150～400毫米的高厚度砂轮,在平衡检查时由于砂轮厚度高,所使用的平衡轴如果不合适往往会影响平衡检验的精确性。现在制造厂通常所采用的三爪、四爪平衡轴,为使轴适应砂轮标准规定的公差范围并使轴能顺利穿入砂轮孔内,在制做平衡轴时就必须将轴做成具有一定的锥度。但使用这样的轴穿入砂 At present, China’s abrasive tool factory production of 500 ~ 750 mm in diameter and a thickness of 150 ~ 400 mm high-thickness grinding wheel, due to the high thickness of the wheel in the balance check, the balance of the shaft if not used will often affect the accuracy of the balance test . Now manufacturers usually used three claw, four claw balance shaft, so that the shaft to adapt to the standard tolerance of the wheel and allow the shaft to penetrate the wheel hole smoothly, when making the balance shaft shaft must be made with a certain Taper. But using such a shaft penetrates the sand
