Surface finishes for CNC machining

Unlike 3-D printing or casting, CNC machining will leave visible tool marks on finished parts. Depending on the task or application, a surface application may be required on metal components. Surface finishes can improve surface hardness, corrosion resistance and aesthetics. JT&M offers a variety of surface finishes to suit the material and your aesthetic preferences:

  • As machined (raw)
  • Polished
  • Brushed
  • Bead blasted
  • Powder-coated
  • Type II anodizing (matte)
  • Type II anodizing (glossy)
  • Type III hardcoat anodizing
