What Is CNC Machining?
CNC machining is a subtractive manufacturing process where raw material is removed with a variety of precision cutting tools to make a part or product. Advanced software is used to control the equipment according to the specification of your 3D design. Our team of engineers and machinists program the equipment to optimize cutting time, surface finish and final tolerance to meet your specifications. We use CNC machining not only to manufacture parts and prototypes but also to make mold, which can be used for our plastic injection molding or pressure die casting services.
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. With CNC machining, three-dimensional cutting tasks can be accomplished in a single set of prompts.
Short for "computer numerical control," the CNC process runs in contrast to — and thereby supersedes — the limitations of manual control, where live operators are needed to prompt and guide the commands of machining tools via levers, buttons and wheels. To the onlooker, a CNC system might resemble a regular set of computer components, but the software programs and consoles employed in CNC machining distinguish it from all other forms of computation.
Advantage of CNC compared NC
Computer Numerical control opens up new possibilities and advantages not offered by older NC Machines. some of these are
1: Reduction in the hardware necessary to add a machine function. New functions can be prorammed into the MCU as software.
2. The CNC program can be writen and executed directly at the CNC Machine.
3. Any portion of an entered CNC progream can be played back and edited at will.
Tool motions can be electronically displayed upon playback
4. Many different CNC Programs can be stored in the MCU
5. Several CNC Machines can be linked together to a main computer.Programs written via the main computer can be downloaded to any CNC machine in the network.this is know as direct numerical control or DNC
6. Several DNC Sytem can also be networked to form a large distributive numerical control sytem .

CNC Milling Parts
CNC milling is used to apply a machined surface finish on plastic or metal, or for creating complex 3D shapes. We use domestic and imported 3, 4 and 5-axis CNC machining centers with quick-change tooling, programmed using advanced Delcam software
CNC milling is one of the most flexible machining methods and able to make a wide range of custom parts. CNC milling is a cutting process in which material is removed from a block metal or plastic by a rotating tool. The cutting tool (called a "mill") is moved in all three dimensions to cut a desired shape from stock.

CNC Turning Parts
Our CNC lathes enable high speed and quality turning of both plastics and metals. The turning process allows for complex external geometries and internal bores to be generated. Our turning capacity is available for prototypes through to low-volume production.
CNC Turning is a manufacturing process in which bars of material are held in a chuck and rotated while a tool is fed to the piece to remove material to create the desired shape. A turret, with tooling attached is programmed to move to the bar of raw material and remove material to create the programmed result.
EDM / Wire Cutting machining And Surface Grinding
EDM (electrical discharge machining) is a method for cutting holes, pockets and other shapes into hardened steel, as well as imparting a surface texture to the internal cavities of mold tools. A sacrificial electrode in an electrolyte bath discharges a high-powered electric spark to erode very hard materials that would be difficult or impossible to do with any other method. Square pocket holes are often created with this method. With wire EDM, a wire is continuously fed between two spools. When electrically charged, it's able to cut through hardened tool steels quickly and accurately.
Electrical discharge machining( EDM)also known as spark machining, spark eroding, shapes metal by creating sparks that melt tiny portions of the workpiece, and is an exceptionally diverse process that generates no cutting forces. EDM is especially useful in the production of fragile parts that cannot take the stress
Wire EDM machine uses a metallic wire (electrode) to cut a programmed contour in a workpiece. Extrusion dies and blanking punches are very often machined by wire cutting. In the machining area, each discharge creates a crater in the workpiece (material removal) and an impact on the tool (wear of the tool/electrode). The wire can be inclined, thus making it possible to make parts with taper or with different profiles at the top and bottom. The wire is usually made of brass or stratified copper, and is between 0.02 and 0.33 mm diameter.
At Xufeng, we also offer surface grinding, cylindric grinding services.
When surface grinding, the workpiece is held stationary on a horizontal plate. The surface grinding wheel is computer controlled to abrade the workpiece to a precise depth.
CNC Machining Tolerances
we will machine your parts as per tolerance stated on 2d drawings, when we do quote, we will inform you whether we can achieve the tolerance of part drawings or not. if no request for tolerance, we will go as per general tolerances table for CNC machining, metal is DIN-2768-1-fine and for plastic, DIN-2768-1-medium.
Tolerances are affected a lots by part structure and type of material.
Our salesman will consult with you on every part of your project and will seek to provide the highest degree of precision possible.
CNC Machining Materials
We are capable a wide range of plastic ( PP, PA6, ABS, PMMA, PC, PVC, POM, Bakelite etc.) and metal materials including Aluminum, brass, copper, bronze, titanium.
With a range material and finishing choice and guaranteed quality by advance inspection equipments, you can trust us, you will receive great parts every time. Once you send us your 3D or 2D file, our engineers will check your design for manufacturability to ensure that the part can be made to your expectations and budget requirements. inquiry us today for a free quote!
