Original Press Release:
Full Bore® Chuck From Lexair Supports Large Bar Stock, High Spindle Speeds
LEXINGTON, KY (December 6, 2005) - The Lexair/Production Dynamics Full Bore® Chuck is a mechanical grip, air-release front mounted collet chuck designed to make the full spindle bore available to handle larger bar stock.
The Full Bore Chuck design eliminates the conventional draw tube and external actuator. Air is used only to open the chuck. Spring force holds the workpiece while it is being machined, and the part remains clamped even if air pressure is lost. Since the clamping force is constant regardless of spindle speed, higher speeds can be reached during the machining operation. Clamping force is adjustable by tightening or loosening the collet using the spanner holes.
The Full Bore Chuck features adjustable concentricity and dead-length positioning to allow hex, round and square bar feeding with fast collet or pad changes. Pads are available in 1/16" increments for round smooth stock and most sizes for round serrated, hex and square stock. It is available in nine models with diameters ranging from 6.75" to 14".
Lexair, Inc. manufactures and markets heavy duty, precision hydrodynamic bar feed systems; magazine style short bar loaders; fixed length, direct mount and wrench operated collet chucks; mechanical grip air released collet chucks; precision dead-length collet chucks; and collet workholding systems.
