Services
Precision CNC Machining
Our precision CNC machining services utilize industry-leading equipment to produce complex components with tight tolerances. With capabilities in milling, turning, and multi-axis machining, we work with materials ranging from aluminum to exotic alloys. Our experienced machinists ensure dimensional accuracy and surface finish quality for prototype through production quantities in defense, aerospace, and industrial applications.
Manual Machining
Manual machining services support complex operations, prototyping, and low-volume production. Our equipment includes Bridgeport mills, Colchester lathes, and precision grinders. This approach offers flexibility for custom work and repair projects requiring hands-on expertise. We maintain tolerances down to .0001" using traditional machining techniques complementing our CNC capabilities.
Welding and Fabrication
Our welding and fabrication services include TIG and MIG welding of steel, stainless steel, and aluminum. We handle projects from small components to large assemblies up to 48" x 72". Capabilities include custom jigs, fixtures, and industrial equipment fabrication. Certified welders work with detailed CAD models or reverse-engineered components to meet exacting specifications for various industries.
Value Added Services
We coordinate value-added services through trusted partners to provide complete solutions. These include surface treatments like anodizing, heat treating, precision grinding, and non-destructive testing. Our general contractor approach ensures quality control across processes such as EDM, casting, and sheet metal work. These services maintain tight tolerances and material integrity for finished components.
Rapid Prototyping
Our rapid prototyping services transform concepts into functional prototypes using CNC machining and 3D printing. We work from CAD models or sketches to validate designs before production. This process supports material testing and form-fit-function verification. We specialize in creating prototypes for complex assemblies and replacement parts with tight tolerances.
