Services
CNC Machining
Our CNC machining services produce complex metal and plastic components with tolerances under 0.001". Using Mazak horizontal machining centers and a 9-axis Integrex multi-tasking center, we handle both high-volume production and prototype development. Our capabilities include milling, turning, and simultaneous 5-axis machining of materials like aluminum, stainless steel, and engineered plastics while maintaining a 99% quality rating through automated inspection systems.
Multi-Tasking Machining
Our Mazak Integrex multi-tasking machining centers enable "done in one" production of intricate parts. With twin spindles and 9-axis capabilities, we machine complex geometries in single setups, reducing lead times while maintaining 0.0003" diameter tolerances. This technology supports aerospace, medical, and semiconductor applications requiring high-precision components from materials like OFHC copper and titanium alloys.
Production Milling
Our horizontal production milling centers with Palletech automation system handle high-volume orders efficiently. The 24-pallet system enables unmanned machining with 120-tool capacity per machine, supporting repeat orders and rush production runs. This system maintains 0.004" general tolerances while reducing setup times through fixed work-holding fixtures and automated tool changeovers.
Prototype Development
We offer prototype development services for validating component designs before full production. Using our CNC machining centers and SolidWorks software, we create functional prototypes from production-intent materials. This process allows dimensional verification through PC-DMIS coordinate measuring systems, ensuring design specifications meet functional requirements before committing to large-scale manufacturing.
Material Selection
Our material selection services help clients choose optimal metals and plastics for their applications. We work with aluminum alloys, stainless steel grades, engineered plastics like PTFE and Ultem, and exotic materials. Our engineers provide guidance on material properties including thermal resistance, corrosion protection, and machinability to ensure components meet performance requirements while maintaining cost-effectiveness.
