静压技术的出现,为提高磨削表面的光洁度开辟了新途径。液体静压轴承有抗振性强、回转精度高、精度保持性好、维修方便等特点。前几年国内多数单位都是在平磨和外磨上推广应用。我们根据生产需要在内圆磨床上进行了试验,经多次反复试制成了一套小孔节流式的液体静压轴承内磨头。经过近三年的使用考验,性能稳定,干磨光洁度比原磨头提高两级左右;湿磨孔径φ10～20毫米的淬硬钢件可达▽_(11),孔径φ20毫米以上,可达▽_(12)。用该磨头磨削,无需对机床进行特殊的精化调整。精
The emergence of hydrostatic technology opens up new avenues for improving the finish of the grinding surface. Liquid hydrostatic bearings have strong vibration resistance, high precision rotation, the accuracy of maintaining good, easy maintenance and so on. A few years ago, most domestic units are in the flat grinding and external grinding on the promotion and application. According to the production needs of our internal grinder on the test, after repeated trial production into a small orifice throttling hydrostatic bearing grinding head. After nearly three years of use test, stable performance, dry grinding finish than the original grinding to improve about two; wet grinding diameter φ10 ~ 20 mm of hardened steel up ▽ _ (11), the diameter of φ20 mm above, up to ▽ _ (12). Grinding with the grinding head, without the need for special refinement of the machine to adjust. fine
