模具是砂轮成型时必不可少的工具,它消耗大、成本费用高。多年来,我们对小砂轮模具不断地进行改革,反复试验,终于找到了小砂轮模具内镶硬质合金的办法,取得了较好的效果。一九七五年前,本厂生产小砂轮。一直沿用45~#钢淬火开合式两半模具。用这种模具生产,装卸模时间长,生产效率低,且生产开合式两半模具工艺比较复杂。针对上述情况,我 Mold is an indispensable tool when grinding wheel, it is expensive, high cost. Over the years, we continue to reform the small grinding wheel mold, repeated testing, and finally found a small wheel mold inlaid with carbide approach, and achieved good results. Before 1975, the factory production of small grinding wheel. Has been using 45 ~ # steel quenching opening and closing mold halves. With this mold production, loading and unloading mold a long time, low productivity, and the production of open and close two and a half mold process is more complicated. In view of the above situation, I
