Services
CNC Milling
Our CNC milling capabilities include 5-axis machining centers with 12,000-16,000 RPM spindles and 30-position tool changers. We handle complex geometries in metals and plastics with tight tolerances. This service supports aerospace and defense industries requiring precision components.
Welding
We provide full welding and fabrication services in dedicated 15,000 sq. ft. facilities. Our team handles steel, aluminum, and specialty alloys for industrial equipment and structural components. Quality is maintained through ASME-certified procedures and non-destructive testing.
5-Axis Machining
Our DMU 125 and MORI SEIKI GV503 machines enable simultaneous 5-axis machining for complex parts. This reduces setup times while maintaining 0.0002" accuracy. Ideal for aerospace components and medical device manufacturing requiring intricate geometries.
Surface Grinding
We utilize Chevalier 1640AD and Landis #1 OD grinders for flatness tolerances within 0.0001". Our capabilities include large surface grinding up to 40" x 63" with automated controls for consistent quality in high-volume production.
Assembly
Our 15,000 sq. ft. assembly area handles complete system integration including mechanical, electrical, and hydraulic components. We support turnkey solutions with 20-ton lifting capacity and dedicated quality inspection stations for final validation.
