在轴上加工对称度小于0.1的键槽,可在万能铣床上用三爪夹头配合尾顶针安装工件,对刀时用图示的对刀装置,准确且快。圆柱棒长度与被加工工件相同,外圆操作时,先磨光,然后校对圆棒与工作台的平行度后压紧夹具,再将垂直支架靠紧圆棒,把百分表的测最头压在铣刀侧刃最高处,锁紧锁表螺钉和表座螺钉,记下百分表读数,然后把对刀装置移至圆棒另一侧的刀刃最高处
In the shaft machining symmetry less than 0.1 keyway, universal milling machine with a three-jaw chuck with the tail thimble to install the workpiece, the knife when the knife on the device shown in the drawings, accurate and fast. The length of the cylindrical rod is the same as that of the workpiece to be machined. When the outer circle is operated, first polish it, then check the parallelism of the round rod and the workbench and then clamp the fixture, and then press the vertical bracket against the round rod to measure the most Press the top of the milling cutter side edge, lock the table screws and table screws, note the dial indicator reading, and then the knife on the other side of the bar to move the highest knife
