答:环形磁钢是无线电行业中广泛应用的元件之一,具有脆、硬、导热率低等特点,很难用一般磨削方法进行加工。若采用双端面磨床以金刚石砂轮来磨削比较理想,但目前各地的磁性材料厂几乎均用车磨床以碳化硅砂轮进行单件单面磨削加工。此外,也有个别磁钢厂在车磨床上采用金刚石砂轮进行磨削,并取得了良好效果。其方法简便,只需把原用碳化硅砂轮改换成金刚石砂轮即可。为了合理使用金刚石砂轮,减少不必要的经济损失,在使用和安装中应注意以下几点: 1.车磨床上所用的金刚石砂轮,可选用粒度80~#～100~#,青铜结合剂,75％浓度,形状为杯形(B),其外径尺寸可选φ200毫米左右,磨削面半径上宽度取15～20毫米,金刚石层的厚度取3毫米。在制造金刚石砂轮时,为了达到砂轮磨削面良好的平整性,最好以金刚石
A: Ring magnet is widely used in the radio industry, one of the components, with brittle, hard, low thermal conductivity, it is difficult to use the general grinding method for processing. If the use of double-sided grinding machine to grind diamond wheel ideal, but almost all of the magnetic material factory around the car grinder to use silicon carbide grinding wheel for single-sided single-sided grinding. In addition, there are a number of magnet mill in the use of diamond grinding wheel grinding machine, and achieved good results. The method is simple, just replace the original silicon carbide grinding wheel can be diamond wheel. In order to reasonably use the diamond grinding wheel and reduce unnecessary economic loss, the following points should be paid attention to in the use and installation: 1. The diamond grinding wheel used on the car grinding machine can be selected from particle size 80 ~ # ~ 100 ~ #, bronze binder, 75 % Concentration, the shape of the cup (B), the diameter of the optional φ200 mm around the width of the grinding surface to take 15 to 20 mm, the thickness of the diamond layer to take 3 mm. In the manufacture of diamond grinding wheel, grinding wheel in order to achieve good smoothness, it is best to diamond
