Precision Turning Machining CNC Parts
Dec 06, 2016

CNC Turning is the manufacturing process in which bars of material are held in a chuck and rotated while a tool is fed to the piece to remove material to create the desired shape. If the center has both tuning and milling capabilities, such as the one above, the rotation can be stopped to allow for milling out of other shapes. Turning parts on CNC turning centers allows for a wide range of complexities, sizes and material types.

  • The starting material, though usual round, can be other shapes such as squares or hexagons. Each bar shape and size may require a specific “collet” (subtype of chuck—that forms a collar around the object).

  • Depending on the bar feeder, the bar length can vary.

  • CNC lathes or turning centers have tooling mounted on a turret which is computer-controlled.

  • CNC’s with “live” tooling, such as those at Pioneer Service, can also stop the rotation and add additional features such as drilled holes, slots and milled surfaces.

      Some CNC turning centers have one spindle, allowing work to be done all from one side, while other turning centers have       two spindles, a main and sub-spindle. A part can be partially machined on the main spindle,moved to the sub-spindle and

      have additional work done to the other side this configuration.

There are many different kinds of CNC turning centers with various types of tooling operations,spindle operations and outer diameter limitations.
