Integrity

You can share your design ideas in a variety of electronic formats including DWG, DXF, SLDW, PDF, JPG, or simply fax in a sketch. Your intellectual property is safe with us. Starrett Tru-Stone engineers take confidentiality very seriously so you don’t have to worry about seeing your design ideas showing up in a competitor’s product.

Materials

Most other granite suppliers work only in granite so they try to solve all of your needs with granite. While granite is our primary material at Starrett Tru-Stone, we have evolved to utilizing many other materials including porous or dense ceramic, carbon fiber and even metals to provide solutions to your unique needs. Our engineers will work with you to select the optimal material for your application. Starrett Tru-Stone leads the industry in quality and capability to provide the right foundation for your precision assemblies.

Assembly Integration

In addition to collaborating on design and build of your machine foundation, our technicians are skilled at value-added assembly. Using precision equipment in our assembly laboratories, we can provide you with the next level assembly, such as adding bearing rails, encoder rails, screw drives, stages, or vibration damping devices. Having this assembly done at our factory provides accountability for accurate performance, which is similar to a consumer’s experience with buying a computer with the software already installed.

TRU-VAC Vacuum Chuck Technology

Starrett 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.

Starrett 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.
