我们针对助力器阀类零件外环槽加工的关键进行了工艺分析,提出了环槽强力成型磨削新工艺的设想。经过两年多的努力,初步实现了这项新工艺(见图1)。要实现所选定的典型零件(见图2)环槽成型磨削工艺,就必须综合考虑砂轮的成型修整、宽砂轮磨削、高速磨削、强力磨削以及与这些工艺特点相匹配的砂轮和冷却液的合理选用。现就我们对成型砂轮的修整,作一简要汇报。一、几种成型修整方法的考虑 1.单粒金刚石修整在通常的情况下,砂轮的成型修整是靠单
We analyzed the key process of the outer ring groove of the booster valve parts and put forward the idea of new technology of the ring groove strength forming grinding. After more than two years of efforts, the initial realization of this new technology (see Figure 1). In order to achieve the typical part of the selected ring (see Figure 2) ring groove grinding process, we must take into account the formation of the wheel dressing, wide wheel grinding, high-speed grinding, grinding and grinding process with the characteristics of these wheels And the rational use of coolant. Now we shape the grinding wheel dressing, make a brief report. First, several forming trimming methods to consider 1. Single-grain diamond trimming Under normal circumstances, the grinding wheel shaping trimming is based on a single
