CNC Milling FAQs

  • What is CNC milling?

    CNC milling is a subtractive manufacturing process where computer-controlled rotating cutting tools remove material from a workpiece to create precise parts. It is ideal for producing complex geometries and offers high accuracy and consistency, commonly used in various industries like aerospace, automotive, and medical.

  • How does CNC milling Work?

    CNC milling works by using computer numerical control to guide a rotating cutting tool along multiple axes, removing material from a workpiece. The CNC machine follows precise instructions from a digital design file, enabling it to shape materials accurately. This process allows for the creation of complex geometries with consistent quality, suitable for a wide variety of applications.

  • How does CNC milling differ from CNC turning?

    CNC milling uses rotating cutting tools to shape the material, while CNC turning rotates the material itself against a cutting tool.

  • Can CNC milling create complex geometries?

    Yes, our multi-axis CNC milling machines are capable of creating complex geometries and intricate features.

  • What is the typical lead time for CNC milled parts?

    The lead time for CNC milled parts is usually between a few days to two weeks, depending on project complexity and volume.

  • What factors influence the cost of CNC milling services?

    The cost of CNC milling depends on material selection, part complexity, required tolerances, and production volume. For example, 3-axis machining generally costs around $40 per hour, whereas 5-axis machining can reach approximately $200 per hour.
