FAQs about CNC milling service

  • What are the benefits of 5-axis CNC milling?

    5-axis machining allows us to machine complex parts from all angles in a single setup. This reduces lead time, improves accuracy by eliminating multiple fixturing steps, and enables the production of intricate geometries—like impellers, turbos, and medical implants—that are impossible with 3-axis mills.
  • Can you machine thin-wall aluminum parts without deformation?

    Yes, machining thin-wall aluminum components is a specialty. We use specialized fixturing, optimized toolpaths, and high-speed machining strategies to manage cutting forces and heat, ensuring dimensional stability and preventing part distortion.
  • What is the maximum size of parts you can mill?

    Our large-format CNC mills can handle parts up to 1500mm x 800mm x 600mm (X, Y, Z). Please contact us with your specific dimensions for confirmation.
  • Do you offer custom CNC milling parts from my design?

    Absolutely. We are experts at producing custom CNC milling parts directly from your CAD data. We provide DFM feedback to ensure your design is optimized for manufacturability, cost, and performance.
  • What surface finish options do you offer for milled parts?

    Beyond the standard milled finish, we offer bead blasting, brushing, anodizing (for aluminum), and powder coating. We can achieve surface finishes as fine as Ra 0.8 μm for critical cosmetic or functional surfaces.
