一、问题的由来为使我国轴承产品打入世界市场,我厂生产了3M6312无心式超精加工机床系列产品。该机床采用超精加工原理,工件以贯穿方式通过旋转单叶双曲面导辊和高频振动的砂块(见图1),图1中件2是轴承的圆柱滚子、轴承外圈等零件,加工后可以改善工件的表面质量、精度、光洁度和耐用度等,其中,圆度由4～5μm提高到1μm以内,光洁度可由▽9提高到▽10～▽11,工件寿命有明显提高。这种方法,比
First, the origin of the problem To make our country into the world bearing products market, I plant the 3M6312 Centerless finishing machine tool products. The machine uses super-finishing principle, the workpiece through the way through the rotating single-leaf hyperboloid guide roller and high-frequency vibration of the sand block (Figure 1), Figure 1, the workpiece 2 cylindrical roller bearing outer ring and other parts , Which can improve the surface quality, precision, finish and durability of the workpieces. The roundness can be increased from 4 ~ 5μm to 1μm, and the finish can be improved from ▽ 9 to ▽ 10 ~ ▽ 11, and the service life of the workpiece is obviously improved. This method, than
