图1所示的加工零件图是曲轴磨床用的打砂轮仿形板之一。材质为W18Cr4V,圆弧半径R=37000mm,弦长l=40mm,弓形高及其误差h=0.0054~(-0.0005)mm。对于这样的圆弧面一般采用手工研磨。研磨技术要求很
The machined part drawing shown in Figure 1 is one of the chamfering plates for a crankshaft grinder. Material W18Cr4V, arc radius R = 37000mm, chord l = 40mm, bow height and its error h = 0.0054 ~ (-0.0005) mm. For such arc generally use manual grinding. Grinding technology is very demanding
