Custom Attribute/Variable Gauges

Kent Machine, Inc. Incorporated is an experienced designer and builder of assembly, test and inspection gauges.

We are a "one-stop-shop" for quick-turnaround custom gauges built to 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 and offer down to a 24 hr turnaround for complex custom precision gauges built to the most stringent requirements for the Orthopedic Medical, Aircraft, Automotive Engine and Transmission, and Off-Road Vehicle industries.

Gauges designed and built by Kent Machine include hand gauges such as flush pin, step, plug, form, spline, and fixture gauges required to do your job. Our gauges also include attribute, variable, in-process, and post process gauges which control the offsets of your grinder, lathe, or other equipment that is either PC or CNC controlled.

Customers depend on Kent Machine's high quality standards (holding extreme tolerances of +/- 0.000040"), and excellent service reputation. Kent Machine surpasses the competition by offering these precision services while meeting, and often exceeding the strictest deadlines for their customers. Kent Machine's online value added services also offer options for ordering and quoting.

Custom Attribute/Variable Gauges Capabilities

Lead Times

At Kent Machine, Inc., our unique and efficient job flow process allows us to 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"

Secondary Operations

Heat Treating
Cryogenic Freeze (Microstructure Stress Relieve)



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.
