Large Capacity CNC Machine and Milling Shop
Since GMFCO first opened its doors in 1975 as a veteran-owned small business, we have been providing superior large metal manufacturing services throughout New England to customers ranging from the Broadcasting to Semiconductor industries-who know they can rely upon us for all their precision CNC machining needs.Our success has not come without hard work, attention to detail, and dedication to ensuring customer satisfaction throughout the design and production process of each CNC machined part we manufacture at our facilities in Hudson, NH.
Advantages of working with a CNC machining company like GMFCO.
We work with our customers throughout the entire custom CNC machining process from conception to final production; and use three metrics to determine a project's success: was it delivered on-time, was it kept on-budget, and did it meet all specification requirements?Furthermore, we provide:
- In-house expertise of CNC machinists who skillfully execute large machined parts for customers who require tight tolerances, tight deadlines and have tight budgets
- Invest in advanced CNC machine equipment to continually improve CNC machining parts quality
- Employ best practices in our large metal manufacturing CNC machining processes to ensure quality is achieved with every project
- Consistently maintain ISO 9001:2000 compliance for all CNC machined parts.
We achieve this level of superior quality with every CNC machining service we provide through our service-oriented project management approach which allows us to:
- Keep the production CNC machining projects running smoothly, thereby keeping costs down
- Focus on the execution of the CNC machining process so that we meet all requirements
- Maintain open flow of communication with our customers keeping them apprised of their project's progress, thereby keeping them on schedule.

More About Large Metal Fabrication
Machine Your Large, Precision Fabrications Cost Effectively with our Toshiba 4 Axis Horizontal Boring and Milling MachineCombined with our two large Gantry Mills, the Toshiba horizontal boring mill is an integral part of our complete fabrication facility. We provide quality, on-time, cost effective machining solutions through all phases of fabrication under one roof. We control the process from start to finish!
We maintain an In-House Certified Welding Inspector.
Tooling to meet your needs
• 90 degree punches and dies• Goose neck (Hawk bill) punches
• Hemming (30 degree forming, acute angle forming)
punches and dies
• Flattening dies
• Offset dies
• Box forming punches
• Radius forming dies
• Rib forming dies
• Urethane
Our seam welders can weld seams on parts up to 12' long. We can MIG or TIG any shape that can be slipped over a mandrel - from flat sheets to cylinders, cones and open-end boxes - diameters as small as 5" to as large as 30".
Simultaneous 5-Axis Milling
The Rotary Table of our Horizontal Boring and Milling Machine allows Multi-Axis Machining of complex and contoured parts without repositioning. The Rotary Table indexing allows three dimensional precision machining of your fabrications.Our 5' x 27' Gantry Mill, outfitted with a rotary positioner, is the machine of choice for those requiring precise features machined in pipe or tube up to 75' long, from 5" diameter to 22" diameter.
Our 8' x 15' Gantry Mill with Right Angle Head attachment is ideal for machining tube sheets, bridge expansion joints, and structural tubes and shapes.
Quickmill Gantry Machining Centers
High speed Vertical MillAmong our vertical Milling Machines is a Mori Seiki NV 5000. With 12,000 rpm spindle speed, 2.6 second chip to chip tool change time, and shaped ways, this baby flies!
