Our Services
Every Service Your Rotating Equipment Needs
From complete gearbox rebuilds to custom gear cutting and precision CNC machining — all under one roof in the Midwest.
One Shop. Total Capability.
One Shop. Total Capability.
Industrial Machine Rebuilders is built around one core principle: when your equipment comes through our doors, it leaves better than new. Our flagship is industrial gearbox rebuilding — but our full-service machine shop means we can handle every component, every repair, and every custom part your operation requires.
Industrial Gearbox Rebuilding
all types, all makes, all sizes.
Complete teardown, inspection, and rebuild of industrial gearboxes of every configuration. We perform gear tooth analysis, bearing replacement, seal reconditioning, housing inspection, and full reassembly to OEM tolerances or better. Every rebuilt gearbox is load-tested before it leaves our shop. When an obsolete unit comes through our doors, we have the capability to cut replacement gears in-house to get your operation back up and running — no waiting on discontinued OEM parts.

Custom Gear Cutting
Any tooth profile. Any module. Any material.
When gears are worn beyond repair or no longer available from the OEM, we cut new ones. Our gear cutting capability covers spur, helical, bevel, and worm gears — cut to print or reverse-engineered from worn originals. We work in steel, stainless, bronze, and specialty alloys.
Our Process
- 1Worn gear measurement and analysis
- 2Reverse engineering if no print available
- 3Material selection and procurement
- 4Precision hobbing or milling
- 5Heat treatment if specified
- 6Final inspection to AGMA standards
