Experience Ultra Accurate Grinding and Polishing the PEG Way

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

Ultra Accurate Grinding: Syringe Barrels, Ground and Polished Tubing, and Pointed Tips Are Typical Components Manufactured at PEG

However, greater sophistication is demanded by new technology. As a result, high-quality, ultra accurate grinding and polishing operations are essential. Therefore, we produce a new generation in precision outer diameter requirements. 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 when specifications demand it. Further, we can handle lengths up to 170”.
