战后,在机械制造业中由於机器精度大大的提高,淬硬及硬质材料的广泛采用,冲锻压加工的改善,都不断的减少了机械加工的裕量, 由於上述原因,磨削加工的范围有了显著的扩大,并大大提高了其加工效果,因而导致磨床的型谱在质量与数量上的改变。 战后发展机械制造业的任务,是扩大磨削 After the war, in the machinery manufacturing industry due to the greatly improved machine accuracy, hardened and hard materials, the extensive use of punch forging improvement, have continued to reduce the machining allowance, for the above reasons, grinding The scope has been significantly expanded, and greatly improve its processing effect, resulting in the type of grinding machine in the quality and quantity changes. The task of developing machinery manufacturing after the war is to expand grinding
