Dowels are insertable in aligned holes vertically defined at predetermined locations through the tool holder. The placement of two pins in a desired alignment relative to a line of reference permits the adjustment of the tool holder upon the face of the turret to locate the tool horizontally at a selected angle with the workpiece. Snap rings are close fitted to the dowels so as to frictionally engage the dowel along its length, fixing the position of the dowels in the vertical holes. In a particular embodiment the lower surface of the tool channel is coplanar with the mounting surface of the tool holder. A shim can be inserted to raise the lower channel surface to accommodate the centerline requirements of lathes designed for larger diameter tools. | |
