Specialty Gear Chucks

The advanced ‘Quick-Pitch' Diaphragm PLD (pitch line diaphragm) chucks, featuring quick change, precision top jaw tooling sets, utilize radius diaphragm chuck technology. They provide fast, 60-second changeouts whenever frequent part-to-part changeovers are required. The system incorporates the use of fixedlength, interchangeable wedge pins that locate and lock on the gear's pitch diameter, work with pieces having virtually any number of teeth and can compensate for varying teeth spacing and pitch values. The Quick-Pitch PLD models can be used on applications with sun, ring, pinion and output gears with spur and helical gear tooth forms.

Four Quick-Pitch chuck units, featuring three three-jaw versions with pitch diameter capacities of 25mm to 100mm; 100mm to 170mm; and 170mm to 245mm; plus a six-jaw unit having 245mm to 350mm gear pitch diameter range are available. The chucks' operating features include pull back action to fixed stops that helps maintain accurate and repeatable workpiece position along with centrifugal force compensation that eliminates the effects of running at today's higher machining speeds. The Quick-Pitch chucks also incorporate weight-saving engineering concepts that help minimize wear and tear on machine tool and grinding system spindles and bearings.
