无心磨上的托板是磨削的支承基准,因此它的耐磨性直接影响工件的几何精度。为了提高产品质量,我们用钢结硬质合金做托板材料进行了试验,实践证明其耐磨性比球铁及GWMn能提高20倍。与硬质合金相当,而制造工艺又简单。现将其工艺过程简介于后,供参考。 1.钢结硬质合金牌号(TLMW 5 Careless grinding of the pallets is the basis of the grinding support, so it’s wear resistance directly affects the geometric accuracy of the workpiece. In order to improve product quality, we use steel bonded carbide as a pallet material for testing, the practice proved that its wear resistance than ductile iron and GWMn can be increased by 20 times. Equivalent to cemented carbide, and the manufacturing process is simple. Now its process outlined below, for reference. 1. Steel Carbide Grade (TLMW 5)
