Gauge Calibration and Repair Services

Kent Machine, Inc. Incorporated is a one stop shop for gauge manufacturing, repair and calibration. If a production gauge or check fixture fails on your production, Kent Machine will repair and precisely recalibrate the gauge in as little a 24 hrs to minimize your down time. At Kent all of our processes, including cryogenic freeze cycling (to stabilize tool steel for grinding) and all heat treating is provided on-site.

In addition, having the unique expertise to build, calibrate and service custom gauges allows us to serve the Aerospace, Off-road, Orthopedic Medical, and Automotive Engine and Transmission Industries with the highest quality and consistency for their custom gauging and fixture needs.

Gauge Calibration and Repair Services Capabilities

Lead Times

At Kent Machine, Inc., our unique and efficient job flow process allows us minimize lead times down to 24 hrs compared with other custom gauge designers that turn around gauges and in-process checking fixtures in 2 - 3 days minimum. This is a significant advantage for turnaround of repairs so that our customers keep their manufacturing downtime to a minimum in cases where production functional gauges break, fail, or fall out of calibration.

Part Size Capability

40" x 50" (Large Transmission Cases for Auto)


to +/- 0.000040"

Specialty Capabilities

Kent Machine Inc. has in-house specialty Heat Treating and Cryogenic Freeze capabilities to insure the quickest turnaround, highest quality, and dimensional consistency for your gauging and checking equipment needs. Our on-site Cryogenic Freeze cycle in (-270 °F) Liquid Nitrogen (HT>Draw>Freeze>Draw) stabilizes and stress relieves the material's molecular structure for maintaining dimensional consistency during the final grinding process, likewise assuring only the tightest tolerances and finest surface finishes for the most precise gauges and inspection fixtures.

KMI also specializes in gauge repair and calibration. Many shops will perform gauge design, build and repair. But few will also perform the calibration and validation in-house. This means Kent Machine Inc. is also a one stop shop for gauge repair (including subsequent calibration). This reduces lead times and increases confidence that the gauge will be repaired quickly and correctly, the first time.
