Custom Attribute and Variable Gauges

Kent Machine, Inc. Incorporated is an experienced designer and builder of attribute and variable inspection gauges.

We are a “one-stop-shop” for quick-turnaround custom gauges inspected using stringent ISO 17025 standards. Our turnkey gauges can be confidently built entirely in-house, including material heat treating. This allows Kent Machine to reduce gauge building lead times for complex custom precision gauges built to the most stringent requirements for the Orthopedic, Medical, Aerospace, Automotive Engine and Transmission, and Off-Road Vehicle industries.

Truama Plate Gauges, Femoral Template Gauges, Bone Cut Gauges, Nail Hole Gauges & Hexalobe Gauges

Gauge Examples for the Automotive, Aerospace and Off Road Vehicle Industries:

Flush Pins, Step Gauges, Plug Gauges, Form and Spline Gauges and fixture gauges to inspect feature locations and size.

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.
