SPV Spintec also manufactures hydraulic chucks in fully customised design. Demand has increased for hydraulic chucks for odd machines not equipped with a standard socket in the spindle. We meet the demand by designing and developing special chucks to suit the customer's application. We have manufactured special chucks for both internal and external clamping, both for holding tools and fixtures for precise clamping of workpiece.




Plusmembranet, for rough milling – The original

The restriction in the use of hydraulic chucks have often been made to utilize cutting conditions for rough milling. The customer is then often forced to buy extra short hydraulic chucks with increased torque. We've eliminated this limitation and offer our customers the opportunity to use our hydraulic milling chucks to save time and money.

The research collaboration with Mälardalen University performed a finite element analysis, from 3D CAD models to verify the results and compare the plus-chuck with a traditional hydraulchuck. The analysis showed very favorable stress concentrations in the calculation which explained the multi-angular membrane's ability to minimize vibration during interventions.
