Large Machine Shop Capacities in OH, IN, MI, NY And PA

About Large Capacity Machine Shops

Large capacity machines shops in Ohio, Indiana, Michigan, New York and Pennsylvania provide large part precision machining services to clients in a variety of manufacturing sectors. Large scale welding and fabrication services are also provided by job shops that can handle large projects and large workpieces. Large capacity machines shops use heavy duty specialized large part machining equipment to repair and manufacture bulky industrial components. Large capacity CNC machines are frequently used to manage the operation and movement of the lathes, cutting machines and boring mills. The three principal machining processes employed by large capacity machine shops are classified as milling, boring (drilling) and turning.

Recommended Large Capacity Machine Shops in OH, IN, MI, NY And PA

Large capacity machine shops with large capacity vertical and horizontal machines in Ohio, Indiana, Michigan, New York and Pennsylvania include the following businesses.  Some of the firms listed below also design and engineer large industrial parts.

Overview of Large Capacity Machine Shops

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.  Large machine shops focus on using subtractive manufacturing methods rather than additive manufacturing technologies.  The machinists and engineers at Kiefer Tool & Mold define a large part to be a workpiece that is over 200 lbs. in weight, over 6″ in diameter and greater than 2′ in length or width. ThomasNet provides a directory of large machining suppliers.

Equipment Required To Move Large Parts and Components

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.

Specifications For Large Part Machining Are Normally Described And Identified By Engineering Drawings And/Or Blueprints

Large capacity machine shops and contract manufacturing companies that produce large fabrications and large machined parts provide ‘build to print manufacturing’ and ‘build to specification manufacturing‘. ‘Build to Print‘ normally defines the manufacturing of a product with an existing design.  Typical specifications for machining large parts include the ID (inside diameter) and OD (outside diameter). Specifications for large part machining also designate the completed workpiece dimensions and often regulate the required finish or surface smoothness on the part or component.
