Cylindrical Grinding

PGS currently uses Swiss made Studer high-precision CNC universal grinding systems to provide our customers with unique high performance cylindrical grinding solutions that can combine multiple wheels and process internal and external geometries in a single clamping. The use of high-frequency grinding spindles combined with a variety of dressing devices to suit the wheel technology being used. Wheels can be prepared with complex profiling through the use of high-accuracy CNC contour dressing with conventional abrasives or touch dressing applications on diamond and CBN super abrasives.

PGS has a complete line of dressing devices, steady rests, and other support equipment to complete the most demanding grinding applications. The image below illustrates a typical Aerospace application where PGS is processing high-temperature Ni alloys with HVOF chromium carbide coatings with a multi-wheel super-abrasive solution. We specialize in processing high value aerospace and defense components with customer certified processes.

With 3-point steady-rest applications we maintain roundness and concentricity at the micron level or below. PGS has invested in centralized coolant systems that pre-filter and fine filter below the micron level to support processing very fine surface finishes on super alloys, nitrided surfaces, and HVOF coated components.
