Cylindrical Grinding

PGS has two Studer high-precision CNC grinding systems (S31 and S40) to ensure the greatest accuracy and flexibility. We use mineral oil as the grinding medium for all grinding operations to provide finer surface-grinding capability and increases the range of materials we can grind.

We use state of the art, high-frequency grinding spindles combined with a variety of dressing devices to suit the wheel technology being used. We perform complex profiling through the use of high-accuracy profile disks and rotary 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 alloys with HVOF chromium carbide coatings with a multi-wheel super-abrasive solution. We specialize in processing high value Prime Rotating Engine components with controlled processes.

With 3-point steady-rest applications we maintain roundness and concentricity at the micron level or below. Our equipment affords us the opportunity to grind internal and external features on complex parts in a single clamping to achieve the highest accuracies.
