Gilman Precision spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Gilman Precision spindles and motor spindles — the American manufacturer from Grafton, Wisconsin, with over 70 years of experience in precision spindles and slides for machine builders and integrators.
Gilman Precision, over 70 years of American expertise in precision spindles
TLDR: Gilman Precision (Grafton, Wisconsin, United States, since 1952) manufactures precision spindle and slide systems for machine builders and automation integrators, with a heritage going back to spindles built for the US Navy in the 1950s and manufacturing still carried out in the United States.
Since 1952, Gilman Precision has been dedicated to advancing high-precision linear and rotary motion solutions, with a heritage going back to spindles built for the US Navy in the 1950s — components demanding absolute reliability and American manufacturing integrity. Unlike other manufacturers that have offshored production, Gilman has maintained United States-based manufacturing, with an 88,000 square foot facility built in 1989 and a dedicated spindle extension added in 1993. The company's class 10,000 clean room, with climate control holding humidity and temperature to within one degree Fahrenheit, makes it possible to hold sub-micron tolerances across production. Gilman manufactures its most critical components in house, including on a SIP machining centre among the most accurate in the world for finish boring of spindle housings and bearing seats, to an accuracy of 1.5 microns.
A range of motorised, cartridge and grinding spindles for critical applications
TLDR: Gilman Precision spindles cover milling, boring, turning, grinding and robotic integration, with motorised spindles whose motor is built directly into the housing for better balancing, angular contact bearings in duplex or triplex arrangements, and hybrid ceramic versions for high-speed applications.
Gilman motorised spindles integrate the motor directly into the spindle housing for better balancing, optimal power transfer and a more compact design, with motor characteristics (speed range, power curve, torque profile) matched specifically to each application rather than taken from a standard catalogue. High-precision angular contact bearings are arranged in optimised duplex or triplex configurations, with hybrid ceramic bearings available for higher speed capability, reduced heat generation and extended life; preload is selected according to actual operating forces and speeds. Gilman boring and turning spindles feature robust housings, high-torque drive options and rugged bearing preload configurations, delivering performance and stability. The grinding spindles, designed for surface, cylindrical and centreless grinding, offer micron-level accuracy.

Frequently asked questions
Do you repair Gilman motorised spindles with the motor built into the housing?
Yes, we work on these spindles, taking account of their duplex or triplex bearing configuration.
Do you work on Gilman grinding spindles (surface, cylindrical, centreless)?
Yes, we diagnose and repair these spindles, preserving their micron-level accuracy.
How long does a full overhaul take?
Allow around 20 working days in the workshop, depending on the condition of the spindle and the availability of parts (bearings, seals, specific components).
Do you work on Gilman spindles integrated into robotic cells?
Yes, we diagnose and repair these spindles, whatever the integration configuration.
Do you offer a preventive maintenance contract for a fleet of Gilman Precision spindles?
Yes, we set up preventive maintenance programmes tailored to the criticality of this equipment.
