The Quick Jaw Change Chuck Advantage

"The Quick-Jaw-Change (QJC) power chuck has become the ideal tool for large and small batch production. The QJC chuck allows the machine operator to change the chuck jaws in 1 minute while retaining very high accuracy, conditions not possible when using a standard chuck. Samchully has increased its range of QJC chucks to include the 20" (500 mm) size. The QJC sizes from Samchully now include the 6", 8", 10", 12", 15" and 20" sizes," said Sidney Roth, President, Samchully Workholding, Inc.

"The QJC chucks offer the following advantages:

• Cost savings through fast jaw change, recover the cost of the chuck in less than 1 year.
• Accuracy, ideal for work with higher accuracy requirements.
• Centrifugal force compensation, no distortion of delicate parts.
• High gripping force when needed for solids and high metal removal rates.
• Never rebore soft jaws, even after many jaw changes.
• Ideal for large and small batch production," said Mr. Roth.

"Wedge-bar operation gives QJC chucks higher accuracy than standard wedge hook chucks. Accuracy on a wedge hook chuck is generally T.I.R of .001". With properly bored soft jaws a 12" QJC chuck operates in the T.I.R. range of .0002" to .0004". It is not possible to achieve this level of accuracy on a wedge hook chuck; the wedge / master jaw connection is not accurate enough to provide this level of precision. QJC chucks are often used in applications where greater accuracy is needed than a standard chuck can offer."

Samchully QJC chucks are available with standard soft and hard jaws, as well as soft and hard monoblock jaws. All Samchully QJC jaws fit other manufacturers QJC chucks, including KNCS, Rota and Ultimate.
