In machining, numerical control, also called computer numerical control (CNC), is the automated control of tools by means of a computer. It is used to operate tools such as drills, lathes, mills, grinders, routers and 3D printers.

According to the function or type of CNC machining parts, CNC machining machine tools can be divided into five types: CNC milling machine, CNC lathe, CNC drilling machine, CNC plasma cutting machine and CNC grinder.

Entry-level CNC laser cutting machines: Costing from $20,000 to $50,000, they work well for cutting materials like metal, plastic, and wood with precision. Mid-range CNC laser cutting machines: Priced between $50,000 and $200,000, these offer advanced laser cutting capabilities and versatility.
