What is CNC turning?

  • The material rod is usually round, but it can also be in other shapes, such as square or hexagon
  • The maximum outer diameter (OD) depends on the feeder. The length of the material rod can vary, but this will affect the maximum output and production efficiency
  • The CNC has a "real-time" tool option to stop rotation and add other functions such as drilling, grooves and milling surfaces
  • Some CNC turning machines have one spindle, which can do all the work from one side, while other turning machines have two spindles, one is the main spindle and the other is the counter spindle. Parts can be partly machined on the main spindle, then moved to the sub-spindle, and perform additional work on the other side of the configuration
  • There are many types of CNC turning machines. They have various types of tool options, spindle options, outer diameter limits, and power and speed functions. Suitable part shapes and machines help reduce production costs.

Is my part suitable for CNC turning?

There are many factors that need to be considered when determining whether parts can be manufactured on a CNC turning machine with the highest cost-effectiveness, but the main ones we need to look at are :

  • The maximum outer diameter of the part you commission, the outer diameter range we can accept is 1mm ~ 50mm.
  • Is the design drawing correct? To avoid money loss caused by subsequent production and final assembly errors
  • Is it the final version of the design? Design changes midway may affect the delivery time
  • Is the material appropriate? Because we are very concerned about application safety and other related issues
