CNC Machining Services: Precision Metal Component Manufacturing

How CIC Specializes in CNC Machining

At Custom Industrials Company (CIC), we specialize in precision CNC machining services that deliver superior dimensional accuracy, exceptional surface finishes, and consistent quality for complex metal components. Our advanced CNC machining capabilities combine 5-axis milling centers, multi-axis turning centers, and Swiss-type lathes to produce intricate parts with tolerances as tight as ±0.0005″. We’ve built our CNC machining expertise over decades of serving demanding industries where precision and reliability are non-negotiable.

What Is CNC Machining?

CNC (Computer Numerical Control) machining is a subtractive manufacturing process that uses computerized controls and rotating cutting tools to remove material from a workpiece, creating custom-designed parts with exceptional precision. CNC machining encompasses multiple processes including milling (where rotating cutters remove material), turning (where the workpiece rotates against stationary cutting tools), and drilling operations. Modern CNC machining centers can perform multiple operations in a single setup, dramatically reducing production time while maintaining tight tolerances and superior surface finishes.

CNC Machining FAQ

What tolerances can CIC achieve with CNC machining?

Our CNC machining capabilities deliver tolerances as tight as ±0.0005" for critical dimensions, with standard tolerances of ±0.001" to ±0.005" depending on part geometry and material. We work with you to determine the optimal tolerance specifications for your application.

What is the maximum part size for CNC machining?

Our vertical milling centers accommodate parts up to 32" x 120", while our turning centers handle diameters up to 26" OD and lengths to 81". For larger components, we offer open vertical milling center capabilities.

Can CIC handle both prototype and production CNC machining?

Yes, we provide comprehensive CNC machining services from single prototype parts through high-volume production runs. Our flexible manufacturing approach ensures competitive pricing and quick turnaround regardless of quantity.

What surface finishes are achievable with CNC machining?

We achieve surface finishes from 16 RMS to 125 RMS depending on material and requirements. Secondary finishing operations including grinding, polishing, and surface treatments are available for applications requiring superior finishes.

How does CIC ensure CNC machining quality?

Every CNC machined component undergoes comprehensive inspection using CMM measurement, optical comparators, and precision gauging. We maintain ISO quality standards with full material traceability and detailed inspection documentation.
