为了迅速地把一块板置于某一精确的角度 ,我用 2 5 .4mm直径的工具钢棒料制作了一套高度规 ,如图所示。将坯料切断 ,并把那些角度使用频率最高的几根磨削成精确的长度 ,意在省去为使板形成一角度而寻找在板下堆积起来的一系列规块。定角度规@杨向明
In order to quickly place a plate at a precise angle, I made a set of gauge gauges using a 2.54mm diameter tool steel bar as shown. Cutting the billets and grinding the ones most frequently used in those angles to the exact length is intended to eliminate the need to find a series of blocks stacked under the board in order to angle the board.
