Q-Tech Precision Clamping Hydraulic mandrels function by expanding or compressing under hydraulic pressure.The hydraulic system is integral and may be manually or power actuated.Extreme accuracy in componenet location is assured as the sleeves expand or contract under equalized hydraulic pressure uniformly from their geometric axis within 0.003mm or less if required specially.These mandrels may be manual or auto actuated depending on the requirement of customer. In auto actuated mandrels centering is performed via. the tailstock center by simultaneous axial pressure against the contact face of mandrel and work piece.

At Q-Tech Precision Clamping we repair all types of hydraulic tool holders.Repair work included oil refilling , seal replacement and torque testing.However it must that the tool holder is not in damaged condition .Only clamping pressure is restored and no geometrical corrections dome. We do not repair jelly filled tool holders. Repairing time is 2 weeks or less.

Expandings mandrels are the ideal solution to many working problems by holding parts In the clamping forces are evenly distributed, reducing distortions during part manufacturing process.Mandrels also provide a superior method of holding parts with high volume short cycle times or which require the highest levels of concentricity.Q-Tech precision clampings supply expanding mandrels tailored to your exact specifications. Many different actuation mehod can be use such as drawbar, cantilever nut and front nut.

We provide custom built collets with bond filled to prevent dust or burr from entering inside. This ensures precision run out and long life. On special request rubber bonded (hot vulcanized) collets can also be provided.
