Grinding & Polishing

PEG specializes in ultra accurate grinding and polishing of cylindrical glass and quartz. Capabilities include: concentric grinding, holding stringent concentricity specifications; demanding outside diameter (OD) tolerances; and concentric steps

Typical Components: Syringe Barrels – Ground and Polished Tubing – Pointed Tips

With greater sophistication demanded by new technology, we are approaching a new generation in precision outer diameter requirements. It requires high quality grinding and polishing operations. At PEG, we can grind and polish very precise cylindrical outer diameters (OD) up to 8” and can hold wall concentricity tolerances to .0005” or better, if specifications demand it. We can handle lengths up to 170”.
