Services
CNC Milling
Our CNC milling capabilities produce complex metal components with tolerances to 0.0001 inches. Using advanced 4-axis machining centers like the Matsuura MC-800 VF, we handle prototypes through production runs for aerospace and medical industries. Our skilled operators program optimized tool paths for maximum efficiency while maintaining strict quality controls through CMM inspection.
CNC Turning
Precision CNC turning operations create cylindrical components up to 12" diameter using advanced lathes including Nakamura-Tome SC-450 and Takisawa multi-tasking centers. Our capabilities include complex contouring, threading, and secondary operations in single setups. We maintain tight tolerances for high-volume production runs serving energy and defense sectors.
Wire EDM Machining
Wire EDM services produce intricate metal parts with complex geometries that traditional machining cannot achieve. Our Fanuc Robocut A-1E system cuts conductive materials with 0.0001" accuracy for precision components in aerospace and medical applications. This non-contact process maintains material integrity while achieving fine surface finishes.
Precision Machining
We manufacture custom precision metal components from prototype to production quantities. Our comprehensive capabilities include CNC milling, turning, and EDM machining for complex parts requiring tight tolerances. With ISO 9001:2015 and AS9100D certifications, we meet stringent quality requirements for critical applications across multiple industries.
Supplier Diversity Solutions
As a WBE-certified supplier, we help corporations and government agencies meet diversity goals while delivering precision machining services. Our certification through the Women's Business Enterprise National Council provides verified supplier diversity solutions without compromising quality or delivery performance for our industrial clients.
