【摘要】 <正> 一、前言高速磨削是近几十年来发展的磨削新工艺,通常在相同的比切除率情况下,较普通磨削可以提高工件质量及砂轮耐用度,而在保证一定的工件质量条件下,则可以大大的提高磨削效率,这对于大批大量生产的某些产品尤为显著。我们于79年研制成功进行120米/秒高速磨削的试验装置(机床),又花了一年左右的时更多还原

【Abstract】 In order to develop high speed (>120m/S)grinding, we studied the change laws of pressure and oil temperature and the pressure change laws as the temperature being constant in cavity of hydrostatie bearings used for grinding wheel at high speeds. We also studied the pressure charateristies of high speed hydrostatic bearings at lower temperature by increasing the tank capacity and pressure cooling.更多还原
