Abstract
A material removal having a plurality of cartridges mounted on an active portion where a plurality of seating members mounted in each of the plurality of cartridges pivots about an axis between a retracted position and an extended position is disclosed. Alternative embodiments have a single pivotable seating member. The pivotable extending seating members operate to extend and retract in a scissors-like motion and enable compact and efficient machining operation, particularly for crank shaft bearing supports.
Claims20
A material removal tool, comprising:
- a housing body including a mounting portion and an active portion;
- a plurality of cartridges mounted on the active portion of the material removal tool;
- and
- a plurality of seating members mounted in each of the plurality of cartridges to pivot about an axis between a retracted position and an extended position, the plurality of seating members including a pocket with a seating surface for a cutting insert.
The material removal tool of claim 11, wherein the plurality of seating members are biased in the retracted position
A method for removing material from a workpiece with a rotating material removal tool, the method comprising:
- inserting an active portion of the material removal tool into a bore of the workpiece;
- positioning a surface of the workpiece to be machined radially proximate a pivot axis of a plurality of seating members mounted in a cartridge mounted on the active portion of the material removal tool;
- actuating the plurality of seating members to pivot the plurality of seating members to an extended position;
- translating the rotating material removal tool in a first axial direction to contact the surface with a first cutting insert mounted in a pocket of a first of the plurality of seating members;
- and
- translating the rotating material removal tool in a second axial direction to contact the surface with a second cutting insert mounted in a pocket of a second of the plurality of seating members.
