• Chuck Diameter (mm): 315
• Number of Jaws: 3
• Through-Hole Diameter (mm): 91
Features:
• Manufactured from high grade alloy steel which extends machine life while providing higher rigidity and greater wear resistance
• The unique design of wedge nut results in its very rigid structure and enables direct power transmission to the master jaws in direct area of jaw guideways - effective counteracting the loss of gripping force and resulting in high power transmission efficiency
• Hardened and ground working surfaces ensure longer life with maintained accuracy and repeatability
• Large through-hole works well with high rotational speeds
• Master jaws secured against throw-off
• Master jaws lubricated directly
• Flat back mounting, dimensions according to DIN 6353
• Special insert set available that allows for easy transformation into a non-through hole model
Application:
• This first class chuck, with increased gripping accuracy, is made for very high precision machining on CNC lathes and turning centres
• Designed for high rotation speeds without compensating elements
Options:
• Special Insert Set allows for non-through hole execution
• Chucks with diameters 500mm, 630mm, and 800mm are avaialble on request
