CNC Milling Services

CNC milling is a manufacturing process. It uses computer numerical control (CNC) to control machine tools and remove material from metal or other hard materials. CNC milling uses a computer program to set production instructions and paths for a workpiece. The milling machine’s cutting tools then move along these paths to accurately cut and shape the material. This technology is capable of producing parts with complex shapes and tight tolerances and is widely used in the automotive, aerospace, medical device and electronics industries. CNC milling provides greater precision, efficiency and repeatability than traditional manual operations, always offers huge advantages for high volume orders.

CNC Turning Services

CNC turning is a precision machining process. It mainly produces symmetrical axis components like spirals, bearings, shafts, and discs. This process relies on a computer numerical control (CNC) lathe. It uses the lathe to create the shape by rotating the workpiece. It cuts along many axes with a tool. CNC turning enables high-precision and high-complexity designs. Computer control systems ensure the quality and sameness of each part. This method improves efficiency and reduces human error. It’s widely used in industries requiring high-precision parts, like automotive, aerospace, and medical equipment.

EDM Machining Services

The processing principle of EDM machine tools is a nontraditional material processing method based on electric spark discharge. Its core uses pulsed spark discharge between the tool electrode and the workpiece. The metal is then melted and vaporized at high temperatures to achieve processing purposes.

EDM processing is suitable for processing high-hardness materials and complex-shaped molds and parts. It is also commonly used for material cutting and grooving. If the tool breaks inside the product hole during processing, we can also remove it with EDM processing.

EDM is an excellent choice for processing small parts, volatile parts, and sharp corners. It can also achieve a high precision of 0.005mm and is often used in combined processing with CNC.

What is CNC Machining?

CNC machining (computer numerical control machining) is simply a processing and manufacturing method that subtracts metal or plastic materials. It uses a computer to write code and process it through CNC machine tools to get the required customized machined parts.

Engineers use UG (Unigraphic), Mastercam, Hypermill, and other programming software to write a series of programs on CAD drawings. This allows us to design the fixture that matches the product, debug the machine, and realize product processing.

During this process, engineers will optimize tool paths to improve processing efficiency. This can improve the ability to design fixtures for simple products, allowing one-time programming to process multiple products. This saves processing time and thus reduces processing costs.

CNC machine tools are usually divided into turning machines and milling machines (3-axis, 4-axis, 5-axis machines). AIXI, with complete equipment, can achieve one-stop product processing.

Applications For CNC Machining Services

CNC machining has stable quality, high machining accuracy, and high repeatability.  It is highly efficient in multi-variety and small batch production, which can reduce the time for production preparation, machine tool adjustment, and process inspection.

CNC milling machining is vital in manufacturing aerospace components and standardizing the process. Aerospace equipment uses a variety of hard metals and specialty materials to create parts ranging from decorative to critical functions. CNC milling can better complete difficult-to-machine materials, such as nickel-chromium super alloy Inconel and 17-4PH stainless steel. CNC Milling is also essential for the manufacture of precision steering equipment.

Machine shops also use CNC milling machines to make many of the parts used to manufacture agricultural equipment. CNC machining manufacturing has large-scale, short-term production capacity.

The energy industry uses CNC machining to mass-produce components for various applications. Nuclear power plants require delicate parts, and the gas and oil industries also rely on CNC machining to produce the parts that keep fuel flowing. Hydropower, solar, and wind energy providers also use CNC milling and turning to manufacture system components that ensure continuous power generation.

Another industry that requires tight tolerances for safety-critical applications of CNC lathes is the oil and gas industry. This department uses CNC milling machines to manufacture precise and reliable parts such as pistons, cylinders, rods, pins, and valves.

These parts are often used in pipelines or refineries that may require small quantities or specific quantities of products. The oil and gas industry often requires corrosion-resistant machinable metals such as 5052 aluminum.

Medical manufacturers use CNC mills and lathes to create essential medical equipment and tools, such as prosthetics, that need precise and unique designs.

CNC machining enables medical devices to keep precise design features on various metal and plastic substrates and quickly create components and products. This helps companies stay ahead of the medical technology curve.

Because the CNC machining process is suitable for one-off custom parts, it has many applications in the medical industry. The tight tolerances offered by CNC machining are critical to high-performance machining of medical components.

Mechanical automation and intelligence are becoming increasingly popular. Many automation industries need to be designed and customized according to customer requirements to meet customers’ different needs. All technology requires precision to work properly. A CNC milling machine follows the design to the final detail. This ensures that products with multiple parts and layers can be assembled quickly without errors or misalignment.

At the same time, CNC milling is fast and convenient. You only need to set up the machine, and the parts can be milled quickly according to the settings. CNC can also create a variety of replacement parts. This is because the turnaround time is fast, and no minimum required part quantity is required.

FAQs about AIXI – China CNC Machining Manufacturer

For AIXI, if the CNC machining custom part size is less than 100mm*100mm, and the milling part only drills a few holes, we only charge about US$50 for the sample fee. For turned parts with a diameter of less than 50mm, the sample fee is approximately US$40.

The processing cost for larger quantities must be calculated based on the drawings. Please provide a PDF and STP or other CAD files to our email, and tell us the material, quantity, and surface treatment. Then, we will provide a formal quotation within 12 hours.

There is no doubt that it has ultra-high precision, surpassing all other processing methods, and CNC processing is fast and has a wide range of uses.

1pcs. AIXI mainly provides rapid prototypes and custom CNC machining services for low volume parts production.

We will process the drawing according to ISO 2768M tolerances if it does not contain special instructions. For our machines, the maximum tolerance can be ±0.01. If you request a tighter tolerance (such as ±0.002), we can combine grinding with a tighter tolerance.

Usually, rapid prototype delivery takes seven days. The processing time is around three days, and the DHL/Fedex/UPS shipment takes three to four days. A normal low volume order usually has a delivery time of two weeks. Of course, it also depends on the complexity of the product.

1. Choose appropriate cutting parameters. Optimizing cutting speed, reducing cutting depth, and increasing feed speed can improve product surface finishes.

2. The selection of tools, materials, and edge radius will also affect the machined surface’s finish. Using high-quality tools, such as high-speed steel tools, can effectively improve the surface finish of the machined surface.

3. Use of coolant: Using high-quality coolant can effectively reduce the friction heat between the workpiece and the tool during machining. Reduce surface roughness and improve surface finish.

4. Increase the number of machining times: Machining the same surface multiple times can gradually improve the surface finish.

5. Polishing: After CNC machining, polishing equipment can be used to polish the surface to further improve the surface finish.

6. Adjustment of machine tool parameters: Ensure that the speed of the machine tool spindle is stable and avoid spindle jitter to reduce the roughness of the machined surface.
