我厂轴承内圈沟道成形,原用自制车床切削加工,刀具易损,椭圆、壁厚常出现超差,基面距较难控制,质量不易掌握,出产效率低,劳动强度大.今年八月我们遵循毛主席“自力更生”、“破除迷信,解放思想”的教导,对车内圈沟道机床进行了大胆的改革,经过近二个月时间,终于改革成功了轴承内圈沟道全自动车床(图1).实践证明:该机床质量稳定,班产量提高一倍,劳动强度减轻,深受操作者欢迎.
I plant bearing inner ring channel forming, the original use of self-turning lathe cutting, tool vulnerability, oval, often appear ultra-poor wall thickness, base difficult to control the distance, the quality is not easy to grasp, the production efficiency is low, labor-intensive. In the month of 2009, following the guidance of Chairman Mao’s “self-reliance” and “breaking superstition and emancipating the mind”, we boldly carried out bold reforms on channel machine tools in the inner circle. After nearly two months, we finally succeeded in reforming the fully automatic Lathe (Figure 1). Practice has proved that: The machine quality and stability, class production doubled, reduce labor intensity, welcomed by the operator.
