我们过去对自动调心型双列向心球面球轴承的内圈,二条沟道是采取一条一条分别在两台机床上进行磨削加工的,产量低,机床和工时利用率不高,质量也差,有偏心往往返工甚至工件报废,严重地影响生产的进度。在毛主席关于“实践、认识、再实践、再认识”的光辉哲学思想指引下,经多次反复的改革,于去年5月在自制的M8810K摇摆磨床上实现了内圈双沟一次磨削的新工艺。一年多来的生产实践证明:内圈双沟采用一次磨削的加工方法质量稳定,产量高,机床潜力得到发挥,节约劳力,降低成本。现介绍于后。
We used to self-aligning double row radial spherical ball bearings in the inner ring, two channels are taken one by one on two machine grinding, low output, low utilization of machine tools and working hours, the quality is also Poor, there is often eccentric rework or scrapped the workpiece, seriously affecting the progress of production. Guided by Chairman Mao’s glorious philosophical thinking of “practice, understanding, re-practice and re-understanding,” after repeated and repeated reforms, the grinding of the double ditch in the inner ring was carried out in a homemade M8810K swing grinding machine last May New Technology. More than a year of production practice has proved that: the inner double-groove grinding process with a stable quality, high yield, the potential of the machine to be played, saving labor and reduce costs. Now introduced later.
