Our Small Part CNC Turning Capabilities

CNC machining has dominated the manufacturing industry for years because of its high precision and repeatability. The process uses high-speed computer-controlled cutting tools to remove material from a solid workpiece and reveal a finished part. Coleys’ part-turning technique is well known for yielding accurate results and quick production times.

Turning small components requires a different style of tooling than large part turning. Small part turning is required when the workpiece being produced is smaller than 1” in diameter (d.). With small components, tool pressure is a primary concern. Very small parts can easily deform during turning operations.

Coleys’ skilled specialists can handle your small parts machining needs with ease on one of our high-speed CNC machines. Our diverse production turning facility is well equipped to produce small Swiss components and CNC chucker parts. From CNC production bar machines to Vertical Turning Lathes, Coleys has the ability to machine the desired shape for your next project.

High-Accuracy Small Turned Parts

These multi-tasking, dual-spindle machines make turning and milling a simple task all in one set-up, shortening your overall cost and lead time. Their synchronized rotation delivers high-accuracy CNC turning parts including:

  • Cylinders
  • Shafts
  • Spindles
  • Axles
  • Journals
  • Bearings
  • Bearing cages
  • Gear blanks
  • Forge nuts
  • Wheels

Advantages and Flexibility

There are certain applications where small-part CNC turning has an advantage over other machining solutions including:

  • Flexible quantities: With decades of experience and the physics of turning compared to milling, we can be flexible in our production. Coleys can produce a few pieces using a chucker or shaft machine, or up to hundreds of thousands using a fully robotic chuck or bar machine.
  • Cost-efficient production: Coleys’ production efficiency allows us to deliver quality parts at lower margins for larger orders. We also offer great rates on small-run orders as well.
  • Material capabilities: We produce turned parts using a wide array of plastic and metal materials such as aluminum, copper, brass, steel, alloys, stainless grades, and exotics.
  • Broad sizing options: We can run Swiss, screw, and turn parts on multiple machines of every size ranging from 6”, 8”, 10”, 12”, 15”, 18”, 21”, 24”, 39”, and 40” chucks with diameters ranging from .125 d. to 50” d.


Our CNC turning services benefit a wide range of industries, including:

  • Semiconductor industry
  • Aerospace industry
  • Automotive Industry
  • Electronic industry
  • Machine tool industry
  • Medical industry
  • Military industry
  • Plumbing industry
  • Food industry
