Grinding frock of bearing inner race terminal surface

The utility model provides a grinding frock of bearing inner race terminal surface, include with treat the grinding inner circle with outer lane, isolating ring and a plurality of steel ball of model, a plurality of steel balls evenly set up in the outer lane and treat between the inner circle of grinding that adjacent steel ball separates through the isolating ring, the width of outer lane is lighter than the width of treating the grinding inner circle to the messenger treats that the both ends face of grinding inner circle can contact and accept the grinding with two grinding wheel that direction of rotation is opposite, and the both ends face of outer lane does not contact with grinding wheel. The utility model discloses simple structure, convenient operation when guaranteeing the machining precision, has improved machining efficiency. 种轴承内圈端面的磨削工装，包括与待磨削内圈同型号的外圈、隔离环以及多个钢球，多个钢球均匀设置在外圈和待磨削的内圈之间，相邻钢球通过隔离环隔开，外圈的宽度小于待磨削内圈的宽度，从而使待磨削内圈的两端面能够与两个旋转方向相反的磨削砂轮相接触而接受磨削，且外圈的两端面不与磨削砂轮相接触。本实用新型结构简单，操作方便，在保证加工精度的同时，提高了加工效
