Overview of Large Capacity Machine Shops

Large scale welding and fabrication services are also provided by job shops that can handle large projects and large workpieces.  The three principal machining processes employed by large capacity machine shops are classified as milling, boring (drilling) and turning. Large capacity CNC machines are frequently used to manage the operation and movement of the lathes, cutting machines and boring mills. These shops use extremely large CNC machines, lathes, mills and equipment to machine really big and complex steel, metal and alloy parts.  Other services provided by custom large component manufacturing companies include burning, heat treating, reaming, steel cutting, shearing, shaping, electroplating fabrication, inspection, painting and assembly.  Large capacity machines shops provide both production and prototype parts.  Machinists at these large capacity shops use large machines and tools to perform large diameter turning, boring, precision tapping, planing, grooving, vertical, horizontal, and angled surface machining. Large capacity machine shops typically work with materials such as steel, metal, metal alloys and rarely plastics and composites.  Kiefer Tool provides manufacturing companies with hydraulic press repair, hydraulic press maintenance, on-site inspections, on-site repairs, technical support and field services.  We provide on-site field inspections for many types of industrial manufacturing equipment and machinery.  Rates start at $100. per hour.

Equipment And Machines Used During The Process of Machining Large Steel and Metal Parts and Components

A Flexible, Large Square Foot Machine Shop With A High Ceiling

  • Machines set up in a machine cell environment
  • Large bay doors or loading Docks
  • 8 foot wide walk ways
  • 15-20 feet of working area below crane bridges
  • 480 volt electrical capacities

Specialized Equipment For Moving Large Parts And Workpieces Including Forklifts, Hoists, Overhead Cranes And Rigging Hardware

Large capacity machines shops generally use large hoists (5 tons or more) and cranes that can handle parts up to 60,000 pounds or more. These hoists often run the length of the manufacturing facility which allow the machine shop employees to move really big and heavy parts around the plant. Cranes with at least 24 feet under the bridge also enable a large capacity machine shop to work on enormous parts. Forklifts or lift trucks also come in handy at large capacity machine shops, manufacturing factories and warehouses for moving heavy parts and components.

Featured Large Machine Shops and Large Part Fabricators

Dowding Machining
Overview: Companies such as Dowding Machining in Eaton Rapids, Michigan have equipment capable of machining very large parts. They provide precision machining solutions for large components. The largest machine in the shop, a MAG Cincinnati U5 profiler, features not just 100 feet of X-axis travel, but also travels of 12 feet in Y. Some jobs call upon much of that Y-axis span. The firm machines castings for wind-turbine gearbox sections.

Mazak Corporation
Overview: The Mazak Corporation is a global machine tool supplier. Their  North American headquarters and manufacturing campus is located in Florence, Kentucky. They sell and service really big machines. The company uses its own equipment to produce machine tools. Learn how they machine really big parts on a large five-axis machining center. Large part machining companies like Kiefer Tool and Mold of Cleveland, purchase bigger machines from Mazak Corporation so that they can increase the size of the parts they can repair and manufacture. Some parts that are machined using large part machining equipment from Mazak can weigh as much as a small car.
