整径加工方法要点 孔的整径加工如图1所示。用钢球(图1a)或心轴(图1 )的孔的整径加工,即是把具有公盈的淬硬钢球2或整径心轴3推过被加工孔1,此孔的尺寸较之整径工具稍小,结果孔的直径增大而且表面质量也改善。 长度比直径 的孔,使用整径冲头3(图1B)在拉床或专用机床上,将冲头拉 Bore diameter processing method Bore diameter processing shown in Figure 1. With the diameter of the hole of the steel ball (Figure 1a) or the mandrel (Figure 1), the diameter of the hole to be machined 1 is pushed through the hardened steel ball 2 or the full diameter mandrel 3 Smaller than the full diameter tool, the resulting hole diameter increases and the surface quality also improves. Length than the diameter of the hole, the use of full diameter punch 3 (Figure 1B) in the broaching machine or special machine, the punch pull
