CNC machining involves the use of CNC machine tools to process metals and other materials, as well as the manipulation of CNC machining tools. CNC index-controlled machine tools are programmed and governed by CNC machining languages, typically employing G codes.

The CNC machining G code language dictates the Cartesian position coordinates of the machining tool on the CNC machine, controlling factors such as feed speed, spindle speed, tool changer operations, coolant application, and other functions. Compared to manual machining, CNC machining offers significant advantages. Parts produced through CNC machining exhibit high accuracy and repeatability, and the process can fabricate components with intricate geometries beyond the capabilities of manual methods. Numerical control machining technology has seen widespread adoption, with most machining workshops now equipped with CNC capabilities. Common CNC machining methods include CNC milling, CNC turning, and CNC EDM wire cutting (electric discharge wire cutting).

CNC milling employs tools known as CNC milling machines or CNC machining centers, while numerical control turning is performed on lathes referred to as numerical control turning centers. Although CNC machining G code can be manually programmed, machining workshops often utilize CAM (computer-aided manufacturing) software to automatically interpret CAD (computer-aided design) files and generate G code programs to direct CNC machine tools. Prominent brands in the CNC machine tools market include Hass, DMG (Deckel Maho Gildemeister), Mazak, Mori Seiki, Fadal, and Wasino.

The history of the CNC process.

The roots of CNC machining technology trace back to the aviation industry's demands. In the late 1940s, an American helicopter company first proposed the concept.

The inception of CNC machine tools stemmed from MIT's development of a three-axis CNC milling machine in 1952, which began machining aircraft parts in the mid-1950s. Throughout the 1960s, CNC machining, prototyping, and programming evolved into more refined and sophisticated processes.

Certain aerospace facilities boast extensive arrays of CNC machines, with cutting machines being particularly prevalent. CNC machined parts encompass various components such as monolithic siding, beams, skins, bulkheads, propellers, aero-engine casings, shafts, disks, blades, and the intricate chamber surfaces of liquid rocket engine combustion chambers. The initial phase of precision CNC machining development revolved around CNC machine tools with continuous trajectory and trajectory control capabilities.

What is CNC machining used for?

1. CNC machining is utilized for the production of workpieces required in regular production cycles. In industries with cyclical or seasonal market demands, utilizing specific production lines might not be cost-effective. Standard equipment often lacks efficiency, resulting in unstable quality and difficulty in guaranteeing quantities. By storing program and product information after machining the first batch, CNC machining centers enable quick replication with minimal lead time. This approach reduces overall production time by evenly distributing lengthy machining processes across individual workpieces.

2. CNC machining excels in producing high-precision components. While some parts may not be in high demand, their precision and short manufacturing cycles remain crucial. Traditional methods involving multiple machine tools result in extended cycle times and reduced efficiency.

3. CNC machining facilitates batch production. Its flexibility allows for rapid responses to specialized requirements, enhancing market competitiveness through mass production. CNC machining centers are well-suited for small to medium batch production, with the capability for minimum batch production.

4. CNC machining is adept at producing complex-shaped workpieces. Advancements in four-axis and five-axis linkage CNC machines, coupled with CAD/CAM technology, have significantly increased machining complexity. Utilizing DNC ensures that a single program can cater to various processing needs, streamlining the automatic processing of intricate workpieces.

What are the types of CNC machining?

1. CNC drilling: This process employs multi-point drilling to create cylindrical holes in workpieces. The CNC machine feeds a rotary drill perpendicular to the workpiece's surface, resulting in vertically aligned holes with diameters equal to that of the drill.

2. CNC milling: Utilizing a rotating multipoint cutting tool, CNC milling removes material from workpieces. In this process, the machine feeds the workpiece into the cutting tool, usually in the same direction as its rotation.

3. CNC turning: This process utilizes a single-point cutting tool to remove material from a rotating workpiece. A CNC machine, typically a lathe, feeds the cutting tool linearly along the workpiece's rotating surface, achieving desired diameters and producing internal and external cylinders, grooves, tapers, and threads. Operational capabilities include leveling, facing, grooving, and thread cutting.

Packing and Shipping.

1. Each product is carefully packed with bubble wrap and placed in cartons. To prevent scratches from impacts during transportation, which could compromise the product's quality and functionality, we utilize specially designed wooden export boxes for packaging.

2. Products are shipped according to customer preferences, including options such as express delivery, air freight, sea freight, and railway transportation.
