PG150砂轮修形器是原西德AGW482滚刀磨床专用于刃磨大螺旋角滚刀时对砂轮进行成形修整的修形装置。该砂轮修形器采用的方法是通过一个廓形仪调用椭圆曲线来逼近砂轮的轴截形，当椭圆曲线调用合适时，可达到较高的修形精度。这里的关键就是要找到一条与砂轮轴截形最接近的椭圆曲 PG150 grinding wheel shaper is the original West Germany AGW482 hob grinding machine used to sharpen the large helical hob when the grinding wheel shaping shaping device. The method used by the wheel shaper is to approximate the shaft truncation of the grinding wheel by calling a elliptic curve with a profiler, and when the elliptic curve is called properly, a higher truing precision can be achieved. The key here is to find an ellipse that is closest to the truncation of the wheel spindle
