前言 磨具根据使用情况,有时必须将它的原有硬度加以改变,进行升硬或降软,以达到符合使用要求的目的。关于陶瓷及树脂结合剂磨具硬度的升硬或降软现已有成熟的经验,但有关橡胶结合剂磨具升降硬度的方法,迄今尚未见有何文献及资料记载。为此,我们在这方面进行了一些试验工作,摸索出一种将橡胶磨具硬度降软的办法。现介绍如下。 Foreword Abrasives according to the use of circumstances, and sometimes it must be its original hardness be changed, the hard or soft, in order to meet the requirements of the use of purpose. There are mature experiences on the hardness increase or decrease of the hardness of ceramic and resin bond abrasives. However, there is no literature or data on the method of increasing and decreasing the hardness of rubber bond abrasives. To this end, we have carried out some experiments in this area and worked out a way to reduce the hardness of rubber abrasives. Now introduced as follows.
