铣刀磨好以后,要测量它的前角和后角,如果没有专用工具,测量起来不但困难,而且也不精确。现在我来介绍一种苏联的铣刀量角仪,它的构造简单,使用起来既简便又精确。构造:如图1所示,1是弓形板,上面刻有各种齿数铣刀的度数指标。2是水平规尺,装在1的一端,可在水平方向左右移动,用螺钉3来固定。4是扇形板,装在1上,可以在一定范围内移动,并可用螺钉5来固定。扇形板上刻有度数,从0向右的25°是量前角用的,从0向左的35°是量后
After grinding the mill, measure its rake angle and relief angle, which are not only difficult but also inaccurate to measure without a dedicated tool. Now let me introduce a Soviet milling cutter goniometer, its structure is simple, easy to use and accurate. Structure: As shown in Figure 1, 1 is a bow plate, engraved with a variety of teeth on the number of cutter index. 2 is a horizontal scale, mounted on one end of the 1, can move around in the horizontal direction, with the screw 3 to be fixed. 4 is a sector plate, mounted on a 1, you can move within a certain range, and can be fixed with screws 5. Sector fan engraved with degrees, from 0 to 25 degrees right is used for the amount of rake, from 0 to the left of 35 ° is the amount of
