Quick Change Jaw Power Chucks

SMJ Marketing offers quick change jaw power chucks (KNCS-N), manufactured by SMW/Autoblok – Italy/Germany. These are a unique solution in the applications where the jaw replacement takes place more than twice in 8-hour shift a day. KNCS-N is a patented quick jaw chuck with a high accuracy and unique jaw safety. The chuck body and the internal parts are case hardened and ground for highest rigidity, durability and precision. It has a unique wedge bar drive for high speed. There is minimum loss of gripping forces due to tangentially supported wedge bars. High efficiency of wedge bar drive ensures highest concentricity and repeatability. The change over time from hard jaws to soft jaws including re-boring is reduced from 40-45 minutes to less than 1 minute. This results in minimum set-up time, which ultimately results in productivity and profitability. SMW/Autoblok also manufactures a wide range of high speed power chucks, special power chucks, and rotating cylinders for turning centres, from dia 125 to 1000 mm.
