ABSTRACT:
A method for manufacturing a rotary cutting tool for fabricating a sheet having transverse slits. The rotary cutting tool has a cylindrical body having generally longitudinally extending grooves, and cutting blades. The cutting blades are first fitted in the grooves with the cutting edges seated on the bottom surfaces of the grooves, and the base surfaces of the cutting blades projecting from the grooves are machined with a rotary grinding wheel while the cylindrical body is rotated. The cutting blades are then removed from the grooves and are finally fitted in the same grooves. The cutting edges of the cutting blades can be accurately arranged about an axis of the cylindrical body, and the rotary cutting tool can be easily manufactured.
