Collets & Collet Chucks, Vulcanised

Adept ProSign Pvt Ltd offers FlexGrip range of high precision work-holding system of vulcanised Collets/Expansion sleeves and corresponding power operated pull back collet chucks/expansion mandrels and related accessories. These are exclusively designed and manufactured in India for precision workholding applications in CNC turning centres, machining centres and various other machine tools. They offer multiple benefits, like close geometrical tolerances, e.g., run-out, concentricity, parallelism, etc., on the workpiece. Owing to true straight line contact pattern with the workpiece, they offer more rigid holding, which enables the use of optimum cutting parameters. Add to it, the quick collet change with changing device, in practically less than five minutes, minimal effect of centrifugal force on clamping force at high rpm and compact dimensions, which means that the user has a superior alternative to 3-jaw power chucks and conventional collet chucks. The chucks/mandrels are offered with the necessary adapter plates to suit different spindle nose. These collet based systems are extremely useful to eliminate frequent soft jaw boring and the specific skills. The collets are vulcanised with specially formulated rubber which imparts the necessary flexing and vibration dampening capability and also prevents chips ingress. The collets can be manufactured to hold round, hex, square or irregular shape components and offer exceptionally high service life due to heat treated and ground alloy steel segments. Collets/sleeves can be manufactured with smooth or serrated holding surfaces based on application needs. Currently, the range includes pull back chuck PBC65 (holding capacity OD 6 mm-65 mm) and PBC100 (holding capacity OD 16mm-100mm), related collets and accessories. Also available is ID expansion mandrel EMC-50E (holding capacity 30 mm-55 mm) and related sleeves. Further range expansion in sizes, viz., PBC42, EMC-25E and EMC-63E are under development, as also dead length chuck variety DLC42, DLC65 and DLC100 and stationary collet chucks for non rotating work. Tailor made solutions can also be offered in accordance with application requirement.
