目前,在制作厚度较小的金刚石砂轮时,普遍采用如下三种方法:①在金属芯板上镀镍后再团结磨粒的方法;②以热硬化树脂结合剂固结磨粒的方法;③将铜粉与磨粒混合,压制成型后烧结的方法,然而在实际应用中发现,上述三种方法都分别存在着一些不足之处。如用方法①制成的砂轮,只有一层磨粒,砂轮寿命短。用第②种方法团结合剂对磨粒的把持力 At present, in the production of smaller diamond grinding wheel, the following three commonly used methods: â ’¢ in the metal core after nickel plating and then solidified abrasive method; â’¡ with heat curing resin binder consolidation abrasive method; â’ The copper powder and abrasive particles are mixed, pressed and sintered. However, in practice, it is found that there are some shortcomings in the above three methods. As with the method ① made wheel, only a layer of abrasive, wheel life is short. With ② the first method of group binding agent on the abrasive force
