High-precision diaphragm three-jaw hydraulic chuck, with rear-pull clamping by the hydraulic cylinder.Lightweight design, featuring a small size and light weight of the chuck.Built-in anti-centrifugal design, with a high rotational speed of 8000 RPM.The chuck body is sealed, dustproof, waterproof, and chip-proof, requiring low lubrication and low maintenance.There is no sliding wear on the chuck body, enjoying a long precision life and being suitable for clamping and processing high-precision workpieces.The clamping force can be precisely adjusted through the output of the hydraulic cylinder.It is suitable for clamping and processing thin ring parts, thin pipe parts and fragile parts, and can work with CNC lathes or precision grinding machines.The installation dimensions are universal for hydraulic three-jaw chucks of the same specification. The clamping force can be adjusted to be stronger or weaker by means of jaw modification.
