State-of-the-art CNC milling services executed with tight tolerances and repeatable accuracy. Supports complex geometry requirements across multiple industries from single prototypes to production runs.
Complete assembly services including fabrication of assembly fixtures and weld tooling. Parts move seamlessly from lathe machining through assembly under one roof, preserving quality control throughout.
Rigorous dimensional verification using CMM analysis, certified granite tables, and first article inspection (FAI) reporting to AS9102 standards—ensuring every machined component meets specification before delivery.
Integrated heat-treat processing through certified supply partners to enhance hardness, strength, and durability of machined components, ensuring full metallurgical compliance within the project workflow.
In-house powder coating, paint shop, and plating coordination deliver protective and functional finishes—corrosion resistance, UV protection, and wear performance—applied as a seamless final step to machined parts.
Our in-house design team uses PTC Creo, CATIA v5, and AutoCAD to translate your concept into a fully engineered machining plan. We clarify tolerances, material specs, and delivery expectations before a single cut is made.

A lathe machinist operates CNC or manual lathes to shape metal, plastic, or composite workpieces by rotating them against cutting tools. They produce cylindrical, conical, and threaded parts to precise dimensional tolerances, reading engineering drawings, setting up tooling, running programs, and verifying finished dimensions against specification.
