铸铁修磨圆弧样板刀,是我处在生产实践中证明行之有效的好方法。它具有速度快、精度高、不啃刀、能修任意尺寸的圆弧和简单易行等优点。修磨时,可先在砂轮上刃磨样板刀毛坯,取后角7°～10°(比所需后角略大2°～3°);在车床上车出长为40毫米至120毫米的铸铁棒料,此铸铁棒的直径即为所需样板刀的圆弧直径;将水(一点即可)和砂轮灰抹在铸铁棒上

Cast iron grinding circular arc model knife, I was in production practice proved to be effective a good way. It has the advantages of fast speed, high precision, not eating knives, arcs of any size can be repaired, and the like. Sharpening, you can first sharpening the sample on the grinding wheel rough, take the clearance angle of 7 ° ~ 10 ° (slightly larger than the required angle 2 ° ~ 3 °); lathe car out for a length of 40 mm to 120 mm Of the cast iron bar, the diameter of the cast iron rod is the arcuate diameter of the required model knife; the water (a little can) and the wheel wipe gray cast iron rods
