TOP Proto is a leading global manufacturer of CNC machining, manufacturing complex and tight tolerance metal and plastic prototype parts through CNC milling, CNC turning, CNC drilling advanced technologies.

What is CNC Machining?

CNC machining is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. The process can be used to control a range of complex machinery, from grinders and lathes to mills and routers. Common CNC machines include 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers. It includes CNC millingCNC turning, and turn milled and more manufacturing methods.


CNC machining offers a great many advantages for production providing:

  • Accurate, repeatable, and expedited processes
  • Incredible range of application
  • Support for many different metals, alloys, and plastics
  • Used to create prototypes and produce volume manufacturing
  • Precise and functional parts and components
  • Producing the casts and moulds used in other manufacturing processes
