Abstract
A cutting disk for a rotary cutting machine includes a disk body having a central axis of rotation and a circumferentially extending outer periphery. A plurality of circumferentially spaced apart cutting teeth is mounted to the outer periphery of the disk body. A chip pocket is defined in the circumferential outer periphery of the disk body between each of the circumferentially spaced apart cutting teeth. Each chip pocket is formed by a chip clearance surface extending radially inwardly into the disk body to form the chip pocket between circumferentially adjacent cutting teeth. The chip pocket is adapted to receive a tooth-produced chip therein, thereby providing more room for chip discharge and thus reducing disk wear.
Claims23
A cutting disk for a rotary cutting machine, the cutting disk comprising:
- a disk body having a central axis of rotation and a circumferentially extending outer periphery;
- a plurality of circumferentially spaced apart cutting teeth mounted to the outer periphery of the disk body;
- and a chip pocket defined in the circumferential outer periphery of the disk body between each of the circumferentially spaced apart cutting teeth, each said chip pocket being formed by a chip clearance surface extending radially inwardly into the disk body to form the chip pocket between circumferentially adjacent ones of the cutting teeth on the cutting disk, such that the chip pocket is adapted to receive a tooth-produced chip therein.
A circular saw disk comprising a central axis of rotation and a circumferentially extending outer periphery having a plurality of circumferentially spaced apart tooth holders disposed on the outer periphery thereof, each of the tooth holders having at least one saw tooth removably mounted thereto, a chip pocket being defined in the outer periphery of the saw disk adjacent each saw tooth such as to receive a tooth-produced chip therein, the chip pocket being defined by a chip clearance surface which extends radially inwardly into the saw disk from the outer periphery thereof to form a cavity defining the chip pocket, the cavity having at least an opening in a radial outer portion of the outer periphery of the saw disk.
A circular saw disk comprising a disk body having a central axis of rotation and a circumferentially extending outer periphery, a plurality of circumferentially spaced apart tooth holders being disposed on the outer periphery of the disk body, each of the tooth holders being adapted to receive a saw tooth mounted thereto, a chip pocket being defined in the outer periphery of the saw disk adjacent each of said tooth holders such as to receive a tooth-produced chip therein, the chip pocket being defined by a curved chip clearance surface extending concavely into the disk body from the outer periphery thereof to form a radially concave cavity in the disk body defining the chip pocket.
A method of forming a more wear-resistant circular saw disk, the saw disk defining a central axis of rotation and having a plurality of circumferentially spaced apart saw teeth removably mounted to an outer periphery of a disk body of the saw disk, the method comprising:
- forming a concave chip pocket in the disk body forward of each of the saw teeth relative to a direction of rotation of the saw disk about said central axis, including forming a curved chip clearance surface extending radially inwardly into the disk body from the outer periphery thereof to form the concave chip pocket between circumferentially adjacent ones of the cutting teeth on the cutting disk, each said chip pocket being adapted to receive a tooth-produced chip therein.
