CNC Machining

CNC machining is the precision backbone of metal fabrication, producing parts with tight dimensional tolerances and fine surface finishes that cannot be achieved by cutting, forming, or welding alone. From simple drilled and tapped holes to complex 5-axis contoured surfaces, CNC machining turns raw metal into finished components. Modern CNC machine shops operate 3, 4, and 5-axis milling centers, CNC lathes with live tooling, Swiss-type screw machines, and multi-tasking mill-turn centers that combine operations in a single setup. Many shops offer complete services from raw material procurement through machining, finishing, and inspection with CMM verification. When selecting a CNC machining provider, evaluate their equipment list relative to your part requirements, their experience with your material, quality certifications (ISO 9001, AS9100), and capacity to meet your volume and schedule needs. Request sample parts or first article inspection reports to verify capability.

CNC Machining FAQ

What tolerances can CNC machining achieve?

Standard CNC machining holds tolerances of +/- 0.005 inches. Precision machining can achieve +/- 0.0005 inches or better. Achievable tolerances depend on the machine, tooling, material, and part geometry.

What is the difference between CNC milling and CNC turning?

CNC milling uses a rotating cutting tool that moves across a stationary or repositioned workpiece to create flat surfaces, slots, and complex 3D shapes. CNC turning rotates the workpiece against a stationary tool to create cylindrical parts like shafts and bushings.
