在加工量具、样板、刀具的圆弧部份时,通常先磨出它的圆柱形表面,然后再在平面磨床上磨制与圆柱表面相连的二侧平面。这个过程要占很多时间,并且在圆柱表面与平面交界的地方很难保持平滑。如果用如图所示的工具,就可以很方便地磨制各种各样的圆弧。这一套工具由12个主要零件组成。图中1是齿条,作直线移动。2是牵引杆,借曲柄拖动或直接用气压或液压机件带动,可作前后移
When machining the arches of a measuring tool, a prototype, or a tool, it is common practice to first grind its cylindrical surface and then grind the two flanks on the surface grinder to the surface of the cylinder. This process takes a lot of time and is difficult to keep smooth at the point where the cylindrical surface meets the plane. If you use the tools shown, you can easily grind a variety of arcs. This set of tools consists of 12 major parts. Figure 1 is a rack, for a straight line. 2 is the tow bar, by the crank drag or directly driven by air pressure or hydraulic parts can be used to move forward and backward
