Advances in Shaft Measurement
The term “shaft measurement system” is standard industry parlance today, but to think of these gages as measuring only shafts is too limiting. For the most part, anything created as a turned part on a lathe is probably well suited for these devices. If there are features such as diameters, lengths, groove widths, fillet radii or chamfers on the part then it is well suited for measurement by a shaft measurement system.
A manufacturer of sub-surface oil well pump barrels needed a better way to check the inside of their barrels for wear. The barrels, some up to 30 feet long, must be periodically removed from the well and checked for excessive wear due to constant plunger motion.
