General Machine and Tool

What General Machine and Tool does

General Machine & Tool, Inc. is a privately held precision machining and fabrication job shop founded in 1962 and headquartered in Lockport, Illinois. The company provides custom industrial machining, fabrication, welding, and mechanical assembly/repair services for heavy-industrial customers including steel mills, oil refineries, power generation, mining, construction, and general manufacturing. Operations span two Illinois facilities totaling 60,000 sq ft: a 40,000 sq ft machining shop in Lockport and a 20,000 sq ft fabrication shop in Joliet. The company is documented to serve a 35+ year customer relationship with Hendrickson Bumper in automotive manufacturing and to handle components ranging from under one pound to over 20 tons.

The company's core technical capability rests on a fleet of 50+ CNC and manual machine tools, including 5-inch horizontal boring mills (Union, Giddings & Lewis, Kuraki), 18-foot vertical boring mills (Betts, Stanko), a 50-inch swing American Lathe for tandem crankshaft machining, heavy presses up to 350 tons (Dake, Rogers, HMP), and overhead crane capacity to 25 tons. Fabrication operations are supported by CNC flame and plasma cutting, shears, brake presses, and rolling equipment, with certified welding procedures in stick, MIG, and TIG across virtually all metals. Notable technical outcomes include machining bolster plates weighing 44,000+ lbs and achieving .002" final run-out tolerance on a bent main frame bearing, demonstrating capability for high-precision, large-scale work.

The business operates on a project-based custom-quote model with no public pricing, selling directly to enterprise industrial customers via field sales, phone, and email rather than through digital channels or intermediaries. Revenue is generated primarily through one-off machining and fabrication contracts as well as mechanical repair/assembly professional services. Marketing is minimal, consisting of a basic website with a project gallery, a LinkedIn page, and a Facebook page, with customer acquisition driven by long-standing reputation, referrals, and the company's ability to deliver turnkey solutions that reduce buyer coordination costs across machining, fabrication, and assembly.

Direct peers

• Xometry: Xometry operates an on-demand manufacturing marketplace connecting buyers with CNC machining, sheet metal fabrication, and other production services. It directly competes for industrial machining spend and offers an alternative sourcing channel that overlaps with General Machine & Tool's customer base.
• Protolabs: Protolabs provides on-demand CNC machining, sheet metal fabrication, and injection molding services to industrial customers worldwide via a digital quoting platform. It is a direct peer because it competes for the same industrial custom-machining and fabrication wallet, though it operates at much larger scale and a more technology-enabled delivery model.
• Hubs (Protolabs Network): Hubs (now part of Protolabs Network) is a global manufacturing platform offering CNC machining, injection molding, and fabrication services. It is comparable to General Machine & Tool as a digital-enabled source for custom machined components, though at a smaller component scale.

Broad incumbents

• Precision Castparts Corp. Precision Castparts Corp. is a large diversified manufacturer of metal components and products for aerospace, power, and industrial markets. It is comparable to General Machine & Tool because both produce precision metal components for heavy industrial customers, though Precision Castparts operates at dramatically larger scale.
• Worthington Enterprises: Worthington Enterprises is a large diversified metal processing and manufacturing company serving construction, industrial, and consumer end-markets. It is a broad incumbent that operates metalworking, fabrication, and pressure-cylinder businesses adjacent to General Machine & Tool's industrial fabrication/machining niche.
• SMS group: SMS group is a global plant engineering and equipment/services provider for the metals industry. It is comparable to General Machine & Tool as a provider of heavy industrial machining, fabrication, and equipment services to steel mills and metal producers, though it operates globally and at much larger scale.
• Graham Corporation: Graham Corporation designs and manufactures engineered heat transfer, vacuum, and fluid-handling equipment for industrial customers including power, refining, and petrochemical markets. It is comparable as an industrial-component manufacturer serving similar heavy-industry customers, though it is a finished-equipment OEM rather than a job shop.

Emerging players

• Fictiv: Fictiv is a digital manufacturing platform that provides CNC machining, 3D printing, and injection molding services. It overlaps with General Machine & Tool in the contract-machining space but focuses primarily on smaller, more standardized parts served via an online quote-to-order workflow.
