用这种多刃切刀(如图)加工三角皮带轮的沟槽,可以大大缩短加工时间,尤其对铸铁件更为适用。切刀前面有直线部分,其长度为2毫米(按沟槽尺寸决定)。在加工时必须十分注意切刀与皮带轮槽底垂直。
With this multi-blade cutter (pictured), the groove of the V-belt pulley can be greatly shortened, especially for cast iron parts. The front of the cutter has a straight section with a length of 2 mm (determined by the groove size). In the processing must pay great attention to the cutter and pulley groove bottom perpendicular.
