What is CNC Machining?

CNC machining is a reduction process that removes material from a workpiece to complete a design. Because the computer controls the entire machining process from start to finish, CNC machining can provide a consistently high level of accuracy and facilitate small or high volume production of identical parts. CNC machining is widely used in various industries for its precision, versatility, and ability to produce complex parts with high accuracy.

What is CNC Machining Used for?

  • Precision CNC machining
  • Fast Machining for low volume manufacturing
  • All kinds of production and rapid prototyping
  • Rapid machined parts requiring high-quality surface finishing
  • Metal and plastic prototypes requiring high tolerance specifications

Advantages Of CNC Machining

CNC machining technology is widely used because of its many advantages:

  • Fast production. The processing speed is fast and the efficiency is high.
  • It is widely applicable to a variety of materials.
  • The processing quality is stable, the processing accuracy is high, and the repeat accuracy is high.
  • Easy customization, suitable for new product development and modification. If you want to change the shape and size of the part, you only need to modify the part processing program.
  • Very suitable for multi-variety, small batch production. The production efficiency is higher and the investment time is less. Compared with developing molds and injection molding production, it is more economical and cost-effective.
  • It can process complex profiles that are difficult to process by conventional methods.
