在铣床上铣削精确角度的工件时,仅靠工作台底座上每格为1°的刻线是很难保证的。我们经常使用三角函数中的正弦公式,借用两块百分表调整工作台的扳转角度。此法既简单又方便。
When milling a workpiece with a precise angle on a milling machine, it is difficult to guarantee the engraving of 1 ° per grid on the table base alone. We often use the trigonometric trigonometric formula to borrow the two dial indicators to adjust the tilt angle of the workbench. This method is simple and convenient.
