半径样板 研磨半径样板是比较复杂的工序。原因是研磨半径和它的结合表面时不许碰坏半径的表面。为此,制造样板时,其最后的研磨工序,可采用两个研磨器:其一是圆的,其直径正好适合样板的图纸尺寸;其二为综合研磨器(图1),系用方条形生铁做成,两侧面形成90°角(或根据图纸的角度成 Radius pattern Grinding radius model is a more complex process. The reason is that it is not allowed to touch a radius of the surface when grinding the radius and its bonding surface. For this purpose, the final grinding step in the production of the sample is achieved by two grinders: one is round and the diameter is just the right size for the drawing of the sample; the other is a comprehensive grinder (Figure 1) Cast iron made of the two sides of the formation of 90 ° angle (or according to the drawings into the angle
