How to determine the cutting angle of the circular blade of the slitter?
1、 Rake angle: it affects the cutting force, cutting edge strength and chip flow characteristics of the blade;
2、 Cut in angle: control the direction of cutting force, effectively reduce the cutting surface, improve chip, and protect the fragile parts of cutting edge;
3、 Cut out surface: ensure that the blade will not rub and squeeze with the workpiece during cutting.
4、 Through the reasonable optimization of the cutting angle of the round blade of the slitter, the cutting edge of the round blade can be strengthened. At the same time, the round blade will not be squeezed by the workpiece material, which is of great help to prolong the service life of the round blade.
