Abstract:
1. A tool arrangement for a cutting machine, the tool arrangement including: a first disk-shaped tool rotatable about an axis and having an axially outer side defining a first maximum tool arrangement boundary along the axis, the first tool having a radially outer peripheral cutting edge portion; a second disk-shaped tool rotatable about the axis and having an axially outer side defining a second maximum tool arrangement boundary along the axis, the second tool having a radially outer peripheral cutting edge portion; and a driving arrangement, at an axial location between the first and second tools, for supporting the first and second tools for rotation and transferring driving force from a transmission member to rotate the first and second tools, a radially outer periphery of the driving arrangement being at a radius less than a radius of the peripheral cutting edge portion of the first tool and less than a radius of the peripheral cutting edge portion of the second tool to permit the first and second tools to engage a material to be cut without engagement of the driving arrangement with the material to be cut, a portion of the driving arrangement including a driving wheel wherein the transmission member is movable within a plane perpendicular to the axis and said driving wheel is within said plane and the driving arrangement includes a bearing that is located within the plane.
