在磨削零件平面时,经常遇到待磨平面与基准面成一定角度,这时只需将砂轮修整成一定角度就可直接磨削零件。如在普通车床上装磨头磨削蜗杆、在平面磨床上磨削一些导轨面等。由于机床本身往往没有修整砂轮角度 When grinding the part plane, often encounter the plane to be polished at an angle with the reference plane, then just grinding the wheel trimmed to a certain angle can be directly grinding parts. Such as wearing a common lathe grinding worm, grinding a few surface grinder and other surface. Because the machine itself often does not trim the wheel angle
