一般工厂要经常磨削R圆弧形刀具或成形样板,如R球面车刀、O型密封圈压模车刀、半圆弧样板等。用光学曲线磨床或修整成形砂轮的办法加工,存在生产效率低、光洁度差、R不精确等缺点。而R车刀的前角也不能沿R圆弧磨出。为此,设计了两种磨削夹具(图1、图2)。用这两种夹具在万能工具磨床上,可磨削R圆弧及刀具的前后角。由于使用这种夹具,并以砂轮圆周连续摆动磨削,加工光洁度可达7～0 ,减少了砂轮的损耗和修整次数。此种夹具操作方便、制造简单、生产效率高、R尺寸精确。
General factory should often grind R circular arc cutter or forming template, such as R spherical cutter, O-ring die cutter, semicircular arc model. Optical curve grinding machine or dressing grinding wheel processing methods, there are low production efficiency, poor finish, R and other shortcomings. The rake angle R can not wear along the R arc. For this reason, two kinds of grinding jigs are designed (FIG. 1, FIG. 2). With these two kinds of fixtures on a universal tool grinder, you can grind the R-arc and the tool’s front and back corners. As a result of the use of this fixture, and the grinding wheel continuous circular motion grinding, machining finish up to 7 ~ 0, reducing wheel wear and repair times. This fixture is easy to operate, simple to manufacture, high production efficiency, R size accurate.
