What is CNC Turning?

CNC machining has dominated the manufacturing industry for years because of its high precision and repeatability.

A computer code containing all necessary dimensions and variables is created and programmed into a lathe machine to produce a part or component through turning. The next step involves the stock material loads into the chuck of the lathe's spindle. The spindle rotates at high-speed intervals while a cutting tool is held against the stock.

As the stock spins on its axis, the cutting tool moves in a linear pattern parallel to the axis of rotation and removes material until the desired shape is achieved for the part. This technique yields the most accurate results and allows for quicker production times.

Part types created by CNC turning includes:

  • Cylinders
  • Shafts
  • Spindles
  • Axles
  • Journals
  • Barings
  • Barring cages
  • Gear blanks
  • Forge nuts
  • Wheels
  • And more!

What is a CNC Turning Center?

A CNC turning center relates to CNC lathes, appearing similar on the outside and functioning as the machine for processing turned parts. However, although lathes are some of the earliest tools used for CNC machining, turning centers are more advanced with higher capabilities.

CNC turn machines add automated tool changing, efficient chip removal, and a straightforward completion of several components. Turning centers take capability to an advanced level, equipped with three, four, or five axes and other tools to enable the device to complete more operations such as turning and:

  • CNC drilling
  • CNC tapping
  • CNC milling
  • Reaming
  • Facing
  • Threading
  • Knurling

The CNC turning center also uses live tooling with a powered rotary tool turret, dual spindles, and Y-Axis.

Types and Configurations of CNC Turning Centers

CNC turning centers are horizontal or vertical, consisting of the same components but differing in orientation.

  • Horizontal turning centers: A commonly used turn center that allows gravity to pull the chips away from the part, more flexible with a longer bed, and can use bar feeders and tail stocks
  • Vertical turning centers: Applies gravity to seat your part into work holding, ideal for machining larger diameters, heavy, short pieces, and small turning components such as transmission gear banks.
  • Horizontal lathes: Horizontal lathes have all the features of traditional lathes. The main difference is that computer programs control them. Their core functions are turning and boring.
  • Vertical lathes: Unlike a horizontal lathe, a vertical lathe holds the workpiece from the bottom before spinning it.
