CNC Turning

CNC Turning is a subtractive manufacturing process in the part is rotated while a cutting tool is fed to the piece, removing material to create a finished part. It is primarily used to manufacture parts that are cylindrical in nature and can provide a smooth surface finish.

Capabilities & Standards

Requirement

Capability

Maximum Part Size
  • Turning - Ø8" x 10"
Certain features may impact the maximum part size.
Finishes
  • As Machined - sharp edges are removed and tool marks are visible
  • Bead Blast - sharp edges are removed and provides a matte finish
Coatings
  • Anodize (Type II)
  • Hard Anodize (Type III)
  • Chromate Conversion Coating
  • Flash Chrome
  • Nickel Plating
  • Gold Plating
  • Silver Plating
  • Passivation
Coatings are not done in house, and will increase lead times. More coatings are available upon request.
Secondary Hardware
  • Helicoils
  • Keyserts
  • Press Fit Pins
Custom hardware available upon request.
Typical Lead Time
  • Standard - 10 Business Days
  • Expedite - 1-5 Business Days
Part complexity, quantity, and current capacity will impact these lead times.
