一、在平面工件上磨出特大半径凹圆弧面在工件的平面上要磨削出凹圆弧面,通常用半径与圆弧半径相等的砂轮进行成形磨削或用平形砂轮进行摆动磨削。然而要加工特大半径的凹圆弧面,如半径R为1600mm甚至更大如图1所示的工件,用上述工艺手段,显然是无法加工的。我们采用半径r为50mm的杯形砂轮磨削工艺,完成了特大半径凹圆弧面的磨削加工。用杯形砂轮磨削板状工件平面时,当砂轮主轴 First, in the flat workpiece grinding large radius concave arc surface in the workpiece plane to be grinding concave arc surface, usually with a radius of the arc with a radius equal to the grinding wheel grinding or grinding with a flat grinding wheel . However, the processing of large radius of the concave arc, such as the radius R of 1600mm or more as shown in Figure 1, the workpiece, with the above means, obviously can not be processed. We use the cup-shaped grinding wheel with a radius of 50mm to finish the grinding process of the large-radius concave arc surface. Grinding a flat workpiece with a cup-shaped grinding wheel when the grinding wheel spindle
