Services
CNC Machining
Our CNC machining services handle complex components from prototype to production. With advanced milling centers and turning equipment, we maintain tight tolerances for precision parts. Our team programs and operates machinery to meet exact specifications while ensuring quality control throughout the manufacturing process.
Large Part Machining
We specialize in large component machining with capabilities up to 59" x 120" dimensions. Our equipment handles heavy parts with tight tolerances of .002" and .05mm. This service eliminates middlemen by providing direct machining solutions for oversized industrial components requiring precision work.
In-Place Machining
Our in-place machining service repairs equipment without removal. Using portable tools and specialized techniques, we perform repairs on turbines, conveyors, and other industrial machinery. This approach reduces downtime and labor costs associated with equipment disassembly and reassembly.
Exotic Material Machining
We work with challenging materials like tungsten, molybdenum, and titanium. Our machinists understand the unique properties of these metals and use specialized tooling and techniques to maintain dimensional accuracy while preventing material deformation during the machining process.
X pandrel Mandrel
The patented X pandrel system machines thin-wall parts without distortion. This customizable mandrel holds workpieces with internal features through multiple operations. Using elastic deformation principles, it provides repeatable precision for complex machining and inspection tasks without damaging sensitive components.
