What Is CNC Machining?

CNC machining refers to Computer Numerical Control machining. It’s a computerized manufacturing process where production equipment is controlled by pre-programmed software and code.

Online custom CNC machining parts are generally realized through operations including turning, milling, drilling, or combined technologies. As a top-grade CNC machining service supplier, Jamesli is capable of all operations required to deliver products with superior quality in short lead times.

CNC Turning

CNC turning (also known as subtraction machining) is a manufacturing process where a cutting tool, a typically non-rotating component of the lathe or turning center, removes material from a rotating rigid material until the desired shape is achieved. The CNC-turned parts are rotated during the process.

CNC Milling

CNC milling is a manufacturing process that uses rotating cutters to selectively remove material from a block of the raw substrate. With CNC milling, it rotates the cutting tool to perform precise movements and tasks which help realize the more complex part design.

CNC Drilling

CNC drilling is a cutting process that uses a rotating cutting tool for producing round holes in a stationary workpiece, typically for machine screws and bolts. The CNC drilling parts can be metals, hard plastics, wood, and other rigid materials.

CNC Machining Applications

CNC machining is popular for its high efficiency, accuracy, and cost effectiveness. The CNC machining parts can be applied in a variety of industrial applications including the following:

Automotive Industry

Precision CNC machining is widely used in the automotive industry including the design and manufacturing of automotive engine parts, transmission car parts, custom parts, and prototyping applications. The CNC machining of car parts transform the automobile manufacturing industry with higher efficiency, precision, and stability for more complex and challenging tasks.

Aerospace Industry

As one of the best CNC machining aerospace parts manufacturers in China, Jamesli produces high-quality aerospace components and prototypes with tight tolerance and the highest precision. With our rigorous inspection and quality control, you will be sure of getting the aircraft components that meet your specific requirements and the stringent needs of the aerospace industry.

Medical Industry

CNC machining medical parts are widely used in surgical instruments and medical devices such as implants and prosthetics. Custom medical prototypes and medical components can be produced through CNC machining with rapid turnaround and less cost. CNC technology makes it easy to process tough medical parts and produce complex surgical instruments even in high-volume and high precision.

Consumers Goods

CNC machining is suitable and popular in producing end-use consumer parts. For example, the electronic parts (metal slats, thin wires, housings, panels, etc), phones, laptops, TVs, and any other consumer goods production in any complex shape. CNC machining can handle both rapid prototyping and mass production with high productivity and low cost.

Military Industry

CNC machining provides a reliable solution for producing military parts and components to be used in the army equipment, military aircraft, etc.

Our CNC machining parts are also popular and in great demand in the field of construction (such as windows, doors, and beams), transportation (such as train, ship, and automobile parts), new energy (such as wind turbine parts and solar panel parts), telecommunications (such as cell tower components), and recreation (such as snowboards, skis, and bicycles).
