Tru-Stone provides both standard and custom solutions for processes requiring vacuum chucking, positioning or air-lift part transfer. The innovative Tru-Vac technology integrates the stability and precision flatness of granite with a porous medium, usually ceramic. Tru-Vac can eliminate the need for mechanical clamping with its inherent part distortion or the risk of damage by utilizing vacuum draw at specific locations or distributed over the entire surface of your part or substrate. Conversely, Tru-Vac technology can be utilized to provide positive pressure to allow your delicate parts to glide on a cushion of air from which they can be safely lifted or transferred to the next operation.
Tru-Stone engineers will work with you on design requirements and constraints to select the best porous medium for your application based on surface area, flatness, wear, and desired airflow characteristics.
Tru-Vac technology can be utilized in air chucks smaller than a hockey puck or larger than a conference room table. Vacuum zones can be of nearly any shape by virtue of our CNC milling capabilities. Multiple zones can be utilized to accommodate a variety of part sizes or even to provide a combination of negative and positive pressure for controlled part movement.
