Steel Gearbox

Industrial Maintenance Welding & Machining is known throughout the industry for our ability to fabricate and repair large equipment. Tracing its roots all the way back to the early 1970s, Industrial had to call on all its experience and customer service skills when asked to recondition a gearbox for a steel mill. The equipment was a 5-stand sheet mill gearbox that was used to control a series of five rolling mills, or stands. Using our CNC horizontal boring mill, we repaired all the bores in a single step to a tight tolerance of ±0.001". Although this giant steel gearbox was 9' long, 7' wide, and 9' high, Industrial Maintenance was easily able to maneuver it with our 80-ton lifting capacity. Finally, the steel gearbox was welded back together, painted, and underwent final visual and dimensional inspection. All repairs were done according to customer specifications and guided by a 2D CAD drawing. This large project required between four and six months to complete.
