Abstract
The broach is used in external grooves, pine cone-type, of rotary blowers wheels, broaching. The broach consists of a body (1), on which profile teeth (2) are fitted, followed by a calibration tooth (3). The sinusoidal adjustment of the profile teeth (2) is achieved by means of some screwed pins (4). The profile teeth (2) have sinusoidal cutting edges.<IMAGE>
