我厂滚针车间无心磨床托板 ,原用轴承钢制造 ,每年托板耗资十几万元 ,且费工费时 ,淬火变形也难以控制。利用制作保持架的低碳钢钢带料头、料尾 ,经随轴承套圈渗碳淬火后 ,制作托板 ,效果很好 ,且省时省力。制作过程如下 :( 1 )先把钢带截成所需长度 ,一端钻4ｍｍ的小孔 ,然 I plant rolling workshop careless grinder pallet, the original bearing steel, the annual cost of several hundred thousand dollars pallet, and the time-consuming work, quenching deformation is difficult to control. The use of low-carbon steel making cages head, tail, with the bearing ring after carburizing quenching, making pallet, the effect is good, and save time and effort. Production process is as follows: (1) the first cut into the required length of steel, drill  4mm one end of the hole
