CONTINUOUS TOOL ROTATION TOOL TURRET

A continuous tool rotation tool turret is comprised of a turret head, a plurality of spindles and a motor. The spindles are attached to the turret head. Each spindle is adapted to secure and rotate a cutting tool. The motor simultaneously rotates each spindle. The spindles rotate at an operational speed while the turret head is being indexed. A bevel gear operationally connected to the motor simultaneously rotates a bevel gear attached to each spindle. Air pressure separates the turret head from its rest surface during indexing. The turret head rotates around a manifold which supplies coolant and pressurized air to the turret head. Optionally, a mating wedge and wedge receptacle attached to the turret head and its housing provide for more precise indexing of the turret head. The continuous tool rotation minimizes the time needed to index the turret from one position to another.

Method for Machining with a Continuous Tool Rotation Tool Turret

A continuous tool rotation tool turret is comprised of a turret head, a plurality of spindles and a motor. The spindles are attached to the turret head. Each spindle is adapted to secure and rotate a cutting tool. The motor simultaneously rotates each spindle. The spindles rotate at an operational speed while the turret head is being indexed. A bevel gear operationally connected to the motor simultaneously rotates a bevel gear attached to each spindle. Air pressure separates the turret head from its rest surface during indexing. The turret head rotates around a manifold which supplies coolant and pressurized air to the turret head. Optionally, a mating wedge and wedge receptacle attached to the turret head and its housing provide for more precise indexing of the turret head. The continuous tool rotation minimizes the time needed to index the turret from one position to another.
