There are many factors that make JC Rapid the industry-leader when it comes to custom parts production in the field of turning-milling, but what it really boils down to is our unmatched speed, quality and affordability. Our Proprietary quality-driven process and Advanced production System are at the heart of our operation, but are just two components of our technology platform that has been meticulously designed that not only permits the production of high quality parts, but also streamlines every step, from quotes to shipping, adding value to the customer experience and ensuring the most affordable, controllable and consistent manufacturing process.

What is CNC Turning?

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 turning 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” ( a 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 JC Rapid, 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, such as the one shown above, 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 options, spindle options, and outer diameter limitations.

Is my part a good fit for CNC turning?

While a lot of factors go into determining if a part can be made most cost-effectively on a CNC turning center, some things we look at are:

  • How many parts are needed short-term and long-term? CNC turning centers are generally good for prototypes to short-run volumes.
  • What is the largest OD on the part? For the CNC turning centers at JC Rapid, the maximum OD for colleted (bar feed-capable) parts is 2.5.”
  • Parts over 2.5″ OD are chucked individually, which depending on volume, can contribute to the price.
  • Parts under 1.25″ OD and medium to high volume may be a better fit for the Swiss screw machines.
  • When it comes to machining parts, there are a lot of variables. JC Rapid can help you determine the best way to have your parts made. We have multiple machining platforms and will look for the most economical fit. Even if our equipment is not the best fit for your part, we can point you in the right direction.
