Abstract
A cutting apparatus which includes a rotatable member having an outer surface and a plurality of cutting tool assemblies, wherein each assembly includes a cutting tool mounted in a holder. The cutting tool assemblies are mounted on the rotatable member so that the holder is shielded by the rotatable member, wherein the cutting tool extends beyond the outer surface of the rotatable member a sufficient distance to operate as a cutter.
Claims36
A cutting apparatus, the cutting apparatus comprising:
- a rotatable member having an outer surface;
- and
- a plurality of cutting tool assemblies, each assembly including a cutting tool mounted in a holder, the holders received within an aperture formed in the rotatable member, the aperture having a first end, a second end, and a cavity disposed adjacent to the second end, the cavity having a width dimension greater than the width of a shaft of the cutting tool and a length greater than the length of the shaft of the cutting tool,
- wherein the cutting tool assemblies are mounted on the rotatable member so that the holders are shielded by the rotatable member, the cutting tools extending beyond the outer surface of the rotatable member a sufficient distance to operate as a cutter.
A cutting apparatus including a rotatable member having a helical upstanding ridge, an outer face and apertures for receiving and seating cutting tools disposed about the helical upstanding ridge, the cutting tools each including a shaft and a tip, and the apertures being arranged so that cutting tools located in the apertures are positioned with tips of the cutting tools project radially outwardly of the outer face,
- wherein the helical upstanding ridge includes cavities aligned with and opening to the apertures, wherein the cavities have a width dimension greater that the width of the shaft of the cutting tool and a length greater than the shaft of the cutting tool, so that, in use, when a cutting tool breaks at the shaft, the shaft of the cutting tool can either pass radially inwardly through the aperture and into said cavity, or can be pressed radially outwardly utilising access via the cavity, so that the shaft of a new cutting tool can be received in the holder.
A block for use on a cutting apparatus including a rotatable body and outer surface, said block including:
- a first surface for forming the outer surface of the cutting apparatus;
- and
- a receiving means for receiving a cutting tool assembly, the cutting tool assembly including a holder and a cutting tool, the receiving means including a first end, a second end and a cavity disposed adjacent to the second end, the cavity having a width dimension greater than the width of a shaft of the cutting tool and a length greater than the length of the shaft of the cutting tool,
- wherein the receiving means is positioned so that, when a cutting tool assembly is positioned therein, the holder is located in the receiving means will be shielded by the first surface of the block, and the cutting tool will extend beyond the first surface of the block a sufficient distance to operate as a cutter.
