China CNC Machining manufacturers CNC Machining is the use of CNC machine tools to process metals, etc. It also refers to the processing of CNC machining tools. CNC index-controlled machine tools are programmed and controlled by CNC machining languages, usually G codes. The CNC machining G code language tells the Cartesian position coordinates of the machining tool of the CNC machine tool and controls the feed speed and spindle speed of the tool, as well as the tool changer, coolant, and other functions. Compared with manual machining, CNC machining has great advantages. For example, the parts produced by CNC machining are very accurate and repeatable; CNC machining can produce parts with complex shapes that cannot be completed by manual machining. Numerical control machining technology is now widely promoted. Most machining workshops have CNC machining capabilities. The most common CNC machining methods in typical machining workshops are CNC milling, CNC turning, and CNC EDM wire cutting (electric discharge wire cutting). The tools for CNC milling are called CNC milling machines or CNC machining centers. The lathe that performs numerical control turning to process is called a numerical control turning center. CNC machining G code can be programmed manually, but usually, the machining workshop uses CAM (computer-aided manufacturing) software to automatically read CAD (computer-aided design) files and generate G code programs to control CNC machine tools. The leading brands of CNC machine tools include Hass, DMG (Deckel Maho Gildemeister), Mazak, Mori Seiki, Fadal, and Wasino. The history of the CNC process. CNC machining technology is derived from the needs of the aviation industry. In the late 1940s, an American helicopter company made this proposal. The original idea for CNC machine tools was that MIT developed a three-axis CNC milling machine in 1952. This CNC milling machine has been used to machine aircraft parts in the mid-1950s. During the 1960s, CNC machining prototyping and programming jobs became more mature and sophisticated. Some large aerospace factories are equipped with hundreds of CNC machines, chief among them cutting machines.CNC machined parts include monolithic siding, beams, skins, bulkheads, propellers, aero-engine casings, shafts, disks, blades, and the unique chamber surfaces of liquid rocket engine combustion chambers. The initial stage of developing CNC precision machining is a CNC machine tool based on continuous trajectory and continuous trajectory control. What is CNC machining used for? 1. CNC machining can be used to manufacture workpieces that are put into production on a regular basis. Market demand for some products is cyclical and seasonal. If a specific line is used, the gain is not worth the loss. The processing efficiency of standard equipment is too low, the quality is unstable, and the quantity is difficult to guarantee. After cutting the first batch (batch), the program and related product information can be retained in the CNC machining center. The next time the product is replicated, production can start with little lead time. The working time of the CNC machining center includes the preparation work time and the processing work time.CNC machining centers evenly distribute hours-long single-piece long machining to each workpiece, thereby reducing the average actual working time per production and greatly shortening the production cycle. 2. CNC machining can be used to produce high-precision workpieces. Some workpieces are not in great demand, but they are essential components that require high precision and short manufacturing cycles. Traditional technology requires multiple machine tools to coordinate work, resulting in long cycle times and low efficiency. 3. CNC machining can be used to produce batches of workpieces. The flexibility of CNC machining production is reflected in the rapid response to special requirements, which can quickly realize mass production to improve market competitiveness. CNC machining centers are suitable for small and medium batch production, and the minimum batch production when using CNC machining centers. 4. CNC machining can be used to produce composite-shaped workpieces. The application of four-axis linkage and five-axis linkage CNC machining machines and the maturity and development of CAD/CAM technology has greatly increased the complexity of machining workpieces. The use of DNC makes the processing content of the same program sufficient to meet various processing needs, thus making the automatic processing of complex workpieces easily. What are the types of CNC machining? 1. CNC drilling is a machining process that uses multi-point drilling to create cylindrical holes in a workpiece. In CNC drilling, the CNC machine typically feeds a rotary drill perpendicular to the surface of the workpiece, resulting in a vertically aligned hole with a diameter equal to the diameter of the drill in the drilling operation. 2. CNC milling is a machining process that uses a rotating multipoint cutting tool to remove material from a workpiece. In CNC milling services, CNC machines usually feed the workpiece into the cutting tool in the same direction as the cutting tool rotates. In contrast, in manual milling, the machine provides the workpiece with the opposite rotation to the cutting tool. 3. CNC turning is a machining process that uses a single-point cutting tool to remove material from a rotating workpiece. In CNC turning, a CNC machine (usually a lathe or lathe) feeds a cutting tool in a linear motion along a rotating workpiece surface. Removing material around the circumference until the desired diameter is achieved will produce a CNC-turned part with internal and external cylinders such as grooves, tapers, and threads. The operational capabilities of the turning process include leveling, facing, grooving, and thread cutting. Packing and Shipping. 1. Each product is carefully packed with bubble bags and packed in cartons. In order to cause scratches due to knocks, which will affect the quality and use of the product, we will use wooden boxes specially designed for export for packaging and transportation. 2. All products will be transported according to customer needs, such as express, air shipping, sea shipping, and railway shipping. FAQs. 1.
