About Midwest CNC Services
Midwest CNC Services is based in Waterloo, Iowa. We provide CNC machine repair, spindle rebuild and grinding, and replacement way covers to shops across Iowa, Illinois, Wisconsin, Minnesota, Nebraska, Missouri, and Texas.
What We Do
Three lines of service, organized so you can find the work you need:
Machine Repair
CNC machine repair across spindle, control, ATC, drive, and alignment work. We service Mazak, Haas, Okuma, DMG Mori, Fanuc, Doosan, Brother, Hurco, and 12 other major OEM platforms — plus Amada press brakes and Trumpf lasers. Field troubleshooting where a remote diagnostic can save a teardown.
Learn More →Way Covers
Replacement way covers in bellows, telescoping steel, and roll-up styles. Built to spec for every CNC platform we service — from Mazak Integrex multi-taskers and Haas VF machines to legacy Fadal 4020s and Hitachi Seiki HMCs. Most orders ship in 2–4 weeks. We measure from your original or build to drawing.
Learn More →Spindle Grinding
Spindle rebuilds, regrinds, and rebalancing across 18 OEM platforms — Mazak, Haas, Okuma, DMG Mori, Mori Seiki, Doosan, and on through Fadal and Hitachi Seiki legacy work. Most jobs run 2–6 weeks depending on bearing-pack damage and parts availability. Each brand page has failure modes and lead times.
