Abstract
An adjustable cartridge assembly is provided for a cutting head of a machine tool. The cartridge fixes the back rake angle of the cutting blade so that mere radial adjustment is required to adjust the blade. Moreover, the cartridge includes a support portion that matingly receives the blade and provides support along three contiguous surfaces.
Claims12
In a machine tool having a cutting head adapted for selective rotation by a motor, the cutting head including a blade extending radially outward from the head adapted to cut an associated workpiece, and an adjusting member for moving the cutting blade relative to the cutting head, the improvement comprising:
- a cartridge disposed in the cutting head for selective radial movement relative thereto, the cartridge including a moving assembly that radially moves the cartridge, and further including an elongated cylindrical portion having a flattened region along a circumferential portion thereof and a support portion at one end of the cylindrical portion that receives the cutting blade in fixed relation, the support portion substantially supporting the blade along three orthogonally disposed surfaces so that the back rake angle is maintained constant during adjustment.
A cutting tool for precision boring of a workpiece comprising:
- a cutting head adapted for selective rotation about a longitudinal axis;
- at least one cartridge received in a cavity in the cutting head, the cartridge being temporarily securing the cutting head and subsequently permanently securing the cutting head along one corner of the cartridge, the cartridge being welded to the cutting head along one corner of the cartridge, and
- a hardened cutting blade secured to the cartridge having a predetermined back rack angle that is non-parallel with the longitudinal axis.
