Rexroth Fibro UFMS Hydraulic Supply Unit w/Controller 208V 3-Phase Grinder

Rexroth Fibro UFMS Hydraulic Supply Unit w/Controller 208V 3-Phase Grinder

This is a Rexroth Fibro UFMS Hydraulic Power Unit with an integrated electrical controller, designed to supply pressurized hydraulic fluid to a precision grinding machine. The unit combines a hydraulic reservoir and pump assembly in a floor-standing base with a dedicated high-voltage controller cabinet mounted on top. It was manufactured for Litton Systems Canada Limited and is labeled on the nameplate as "Grinder #3 'FIBRO'" — identifying it as a purpose-built hydraulic supply for a Fibro precision grinder.

Applications

Hydraulic power units of this type are used to supply controlled, pressurized hydraulic fluid to the axis drives, clamping systems, and coolant circuits of precision grinding machines — in this case, a Fibro-manufactured grinder. Fibro GMBH, based in Weinsberg, Germany, was a well-regarded manufacturer of precision machine components and complete grinding systems from the 1970s through the 1990s; their equipment was used in aerospace, automotive, and general precision manufacturing environments across Europe and North America. The integrated Rexroth hydraulic components reflect the common pairing of Rexroth's hydraulic expertise with German machine tool builders during this era. This unit dates from 1982, placing it squarely in the generation of German CNC and hydraulic-assist grinding technology that was widely adopted in North American industrial facilities through integrators like Litton Systems Canada. The controller cabinet provides the electrical control and sequencing logic for the hydraulic functions, with the 4-position mode selector supporting manual, automatic, setup, and indexing-change operating modes as labeled on the front panel. Units like this are sought by shops maintaining legacy Fibro grinding systems or needing a standalone hydraulic power pack for compatible machinery.
