construction, oil and gas, steel, marine, aerospace, and many more. MI is able to cut gears to 250 inches in diameter and grind gears to 102 inches in diameter. Our wide range of machinery includes CNC gear grinders, CNC gear shapers, CNC gear hobbing machines, and Maag gear shapers. We have a large selection of modern CNC equipment including lathes, cylindrical grinders, and multi-axis vertical boring mills.
Full service gearbox repair and test center
MI operates a full service gearbox repair and test center dedicated to the dependable overhaul and enhancement of gear drives. We service most gearboxes regardless of original manufacturer.
MI is able to improve existing gear drives. We have greatly increased the horsepower capacities and service life of many chronically ill gearboxes by analyzing existing components and providing better gears and bearings. We are also skilled at saving existing components and refurbishing parts when possible, resulting in significant savings for our customers.
When necessary, we also assist in redesigning customers’ gear trains using modern engineering tools, current design standards, and state-of-the-art manufacturing technologies.
If there is a need for precision gears and power transmission services. MI is able to not just fix, but improve complex gear drives. Call the precision gear machining experts at Machinists for reliable handling of your project.
