Smooth ring, calibration ring gauge, taper gauge

Smooth ring: as a size reference, it can also be used as a comparative measure, but also directly to check with acceptable build special ring gage calibration ring gauge is the machinery manufacturing industry to ensure accurate and consistent bore size of transfer gauge. The inner diameter of the calibration gas for measuring head, cylinder gauge, bore comparison (long) instrumentation. Bore size is indispensable for high-precision transfer
