Large Part Machining Services at Kiefer Tool & Mold

Kiefer Tool & Mold Inc. is a job shop machine shop located in Cleveland Ohio that specializes in large part and large capacity machining. With our experienced staff of engineers, mill wrights and machinists we can disassemble, inspect and remanufacture components and complete machines. Kiefer Tool machines large parts precisely, quickly and affordably.  From turning large diameters to milling vast surface areas, our facility is equipped to handle a diverse field of large part machining. With both manual and CNC equipment, we can manufacture all shapes and sizes, various alloy steels, and complex geometrical features.  Here at Kiefer Tool & Mold Inc. we define large part machining to be over 200 lbs. in weight, over 6″ in diameter and greater than 2′ in length or width. Our large capacity machine shop services include large part machining, large precision machining, large CNC machining, large diameter turning, long turning capacities, horizontal boring and milling, threading, and keying. Large parts that we machine include power transmission components (shafts, bushings, gears, pulleys, etc.), press frames, platens, hydraulic cylinders, fly wheels, pressure vessels, tanks, flanges, tie rods, and bolster plates, gear blanks, rolling mill components, hydraulic powered machines, aircraft components, mining equipment, railroad equipment, large cast parts, power generation equipment, petroleum and oil drilling equipment, construction equipment, and manufacturing equipment.

We machine bulky and heavy manufacturing equipment parts and big fabrications that are too large for other machine shops to work on because small capacity machine shops don’t have adequately sized work zones or machine tools that are appropriate for large-scale parts. Our large capacity machine shop was constructed with large part manufacturing in mind. Our machinists are capable of keeping tight tolerances when manufacturing extra large machined components. Our machining processes include line boring, large part vertical boring, large diameter turning, hydraulic cylinder boring, custom thread turning and grooving. Our vertical turning and milling center and lathe services are dedicated to large metal part machining, large diameter CNC turning, long turning, large diameter internal turning operations, threading, facing and boring. We can complete rush jobs and we keep tight delivery schedules.


The following are some of the operations and equipment we use to conduct our Large Part Machining services.

With both manual and CNC equipment we are capable of turning, boring, & threading diameters up to 82″ on the outside, and lengths of up to 20′ between the centers.

With both manual and CNC equipment our facility is capable of machining a large amount of surface area to manufacture your parts in need of milling, boring, drilling & tapping.

When your design requires holding tight tolerances or specific surface finishes, our equipment is capable of grinding up to 84″ in diameter and honing bores up to 40″ in diameter.
