为了在普通内圆磨床和万能磨床上加工出高精度,高光洁度内孔,必须提高磨床的精度和性能,尤其是内圆磨具的旋转精度和抗振性能。由于滚动轴承旋转精度的综合误差较大,所以滚动轴承结构的内圆磨具寿命较短,装配困难,往往很难满足上述要求。当前,国内外广泛采用静压轴承式内圆磨具——静压磨头。

In order to produce high-precision, high-finish bore in ordinary internal grinder and universal grinder, it is necessary to improve the precision and performance of the grinder, especially the rotational accuracy and anti-vibration performance of the internal circular grinder. As the rolling bearing rotation accuracy of the larger the overall error, so the rolling bearing structure of the inner circular abrasive short life, assembly difficulties, often difficult to meet the above requirements. At present, widely used at home and abroad hydrostatic bearing type internal grinding - static pressure grinding head.
