Abstract
A rotary cutter grinder that cuts and grinds upon its circumferential surface is well suited for stump grinding and the like applications. The rotary cutter grinder is constituted by a hub portion for mounting to the power output shaft of a prime mover and plural arms unitary with the hub portion. These arms are substantially uniformly spaced about the hub portion and extend radially outwardly therefrom. A cutting tool, usually a tungsten carbide cutting tool, is mounted to each of the arms at a positive rake angle relative to the perpendicular to the direction of motion by the cutting tool.
Claims17
A rotatable cutting device suitable for stump grinding which comprises:
- a rigid hub portion;
- plural arms unitary with said hub portion, substantially uniformly spaced about the hub portion and extending radially outwardly from said hub portion;
- and
- a cutting tool mounted to each of said plural arms, the mounted cutting tools together providing an array of cutting tools about the periphery of the cutting device;
- each said cutting tool having a flank face and a working face together defining an arcuate cutting edge and being mounted to the arm at a positive rake angle.
A rotatable cutter grinder which comprises:
- a rigid, substantially planar hub portion;
- plural arcuate arms unitary with said hub portion, substantially uniformly spaced about the hub portion, and at least some of the arms being laterally offset relative to the plane of the hub portion;
- and
- a cutting tool mounted at a positive rake angle to each of said plural arms at a distal end portion thereof so as to provide an array of cutting tools about the periphery of the cutter grinder.
