Chucks update
From safety to shaftless, chuck technology is advancing with the rest of today's press equipment.
Boschert, LLC (Mobile, Ala.) introduced the VT Style replaceable insert for use with its safety chuck. The efficient design creates longer lasting concentricity between the safety chuck and roll shaft by separating the two forces of wear that breakdown the seat of the chuck, explained Bob Banks Jr., Boschert manager. The VT-7 features a roll shaft journal made of a round part with a square part. The round part accepts the load-bearing footprint of the roll shaft and the square part transmits torque through the safety chuck to the roll shaft. As a result, torque is separated from the load-bearing footprint of the roll shaft, preventing wear to the roll shaft journal. This allows the shaft to remain almost as precise as new throughout the life of the VT-7 replaceable insert.
