Cylindrical Ring Gages

The Material. We use only superb quality steels such as 06 or Alloy Steels such as 8620 and Heat Treat our blanks to a minimum of 58RC.

The Stabilization Process. Subsequent grinding operations can introduce heat and stress. Meyer puts all blanks through a stabilization process, cycling them through temperature extremes from -130°F to +300°F.

The Precision Lapping Process. “Lapping” is the finishing process that removes small amounts of material from the gage surface and brings it within its final tolerance limits.

Inspection with NIST – traceable gages. In our Metrology area conditions are a strict, cool 68°F where the relative humidity is between 30- 50% and all of our masters are traceable to NIST.
