CNC Milling

Precision CNC machining for prototypes and production parts

Overview

CNC milling is a subtractive manufacturing process that uses computer-controlled rotary cutting tools to remove material from a solid workpiece. Our advanced 3-, 4-, and 5-axis CNC milling centers deliver tight tolerances and excellent surface finishes for complex geometries.

We machine aluminum, copper, zinc, magnesium, titanium, and steel alloys — from one-off prototypes to production runs of 10,000+ units. Our engineering team reviews every design for manufacturability before production begins.

Frequently Asked Questions

What file formats do you accept?

We accept STEP (.step, .stp), IGES (.iges, .igs), DWG, DXF, PDF, and STL files. 3D models are preferred for accurate quoting.

What is the typical lead time?

Prototype orders can ship in as few as 2–3 business days. Production orders typically ship within 5–15 business days depending on quantity and complexity.

Do you offer design-for-manufacturability (DFM) feedback?

Yes. Every RFQ receives a free DFM review. Our engineers will flag potential issues and suggest cost-saving modifications before production begins.
