Abstract
A rotatable cutting tool unit of a tool assembly for a cutting machine that is used in conjunction with an associated method of cutting provides several novel aspects. The tool arrangement, which includes two tool units, includes first and second disk-shaped tools rotatable about an axis. The tools define maximum tool arrangement boundaries along the axis. A driving arrangement, at an axial location between the first and second tools, supports the first and second tools for rotation and transfers driving force. A radially outer periphery of the driving arrangement is at a radius less than a radius of a peripheral cutting edge portion of the first tool and less than a radius of a peripheral cutting edge portion of the second tool.
Claims9
A cutting machine comprising:
- an elongate tool carrier mounted to a machine body at a machine-proximate end and having a rotatable cutting tool mounted at a distal end thereof;
- a drive member positioned adjacent to and concentric with the rotatable cutting tool at the distal end of the tool carrier, the drive member being mounted on a rotatable bearing assembly received in an aperture at the distal end of the elongate tool carrier;
- a machine-proximate receiving space defined between two side walls of the elongate tool carrier, said machine-proximate receiving space configured to accommodate a continuous drive loop power transmission operatively engaged between the drive member and a drive motor at the machine body, said machine-proximate receiving space extending from the machine body to at least a perimeter of the rotatable cutting tool;
- and
- a distal receiving space defined between two side walls of the rotatable cutting tool, said distal receiving space configured as an extension of the machine-proximate receiving space, said machine-proximate receiving space and said distal receiving space together constituting a protective operational space for a continuous drive loop power transmission operatively engaged between the drive member and a drive motor at the machine body.
