Plastics

CNC milling of plastics is the most common and economical way to create rapid prototypes and review the appearance and function of your design.

Metals

CNC milling is a popular way to produce both rapid prototyping of metal parts and final parts. Common metals include aluminum, magnesium, steel, brass, copper, etc.

Other Materials

Besides plastics and metals, we can also work with ceramics such as Alumina, ZrO2, AIN, Si3N4, and SiC. Wood and marble are also on our list.

Why Choose Us for Custom CNC Milling?

Cost Efficient

80% of aspect and mechanical parts can be CNC milled within minutes or even seconds by optimizing the tool paths and using special cutting tools. Our automation setup for CNC milling is super cost-efficient for mass production. It helps reduce CNC machining costs compared with additive manufacturing in most cases.

Materials & Finishes Options

Besides our fast turnaround time, we have various types and specs of plastic and metal blocks available for CNC milling processes. We can also provide different surface finishing for CNC machined parts, such as painting, anodizing and chroming. It’s an excellent combination of function and aspect.

Unlock Complexity

Because the cutting tools of a milling machine can approach the workpieces from several different angles, it is possible to create CNC machined parts with complex shapes. With more axes, we can create milled parts with greater complexity. Milling is often the best bet if a project demands an irregular shape.

Our CNC Machining for Various Industrial Applications

We works with leading manufacturers from different industries to support growing demands and streamline their supply chain. The digitalization of our custom CNC machining services helps more and more manufacturers bring their idea to products.
Regardless of the manufacturing process used to create the end-use part, our CNC machining service is widely used by designers as a means of creating early and late-stage prototypes with short turnarounds times. CNC prototyping allow designers to rapidly iterate ideas without tooling costs or waiting times. It is one of the best ways to create concept model and function prototype to verify the design. Compared with other rapid prototyping methods, rapid CNC machining allows us to get tight tolerance prototypes in real materials fast. CNC Prototyping is the preferred option to bring new design life among the other rapid prototyping methods, unless the products are designed for 3D printing or other methods only.
CNC machining and EDM are the main methods to fabricate metal tooling for injection molding, high pressure die casting, blow molding, roller molding, stamping, blending and so on. High speed CNC machines allow us to make high precision copper patterns, mold cavities, mold base, lifter and other mold components in very short term. Moreover, with 5 axis milling machines, we can mill the deep pocket features in hours which take days to make by EDM in the past. That’s how we can speed up the mold making process significantly. Check out how rapid tooling works.
CNC machining has for several years been an integral part of aerospace manufacturing. That’s partly down to the extremely high precision of CNC machines, making the process suitable for safety-critical parts that will be used on aircraft. Machinable aerospace parts include prototype engine components, fuel panels, landing gear components and engine mounts.
In the automotive industry, utilizing a CNC machining service is the most popular way to create concept cars as well as the function testing components, such as lighting, engine, transmission & steering system. It is also widely used to produce high volume automotive parts and post-machining the die casting parts, investment casting parts. It is especially useful for custom automotive parts, which may be required for repairs or for limited-edition luxury vehicles, since it is too costly to make few parts by molding process.
The machinability of many grades of titanium and stainless steel makes CNC machining services widely used in healthcare, with the process regularly used to create implants, medical devices and surgical tools such as scalpels. Tight tolerances and fast turnarounds are especially important for items such as titanium hip implants, which should be tailored to a patient’s anatomy.
Though injection molding dominates the production of simple plastic parts, many off-the-shelf goods are created with CNC machining. Household goods and appliances often contain machined parts, while items like enclosures and fixtures are also suitable for the process. Goods like sporting equipment may also be CNC machined. The CNC machining of metal and plastic components plays a big role in the electronics industry. Items such as laptop casings, connectors and sockets can all be reliably made with a CNC machine.

Frequently Asked Questions

CNC milling is just one of the CNC machining processes available. Milling is a particular form of precision CNC machining. Milling uses a cutter that removes material by moving into the workpiece at an angle. The movement of the cutter is controlled by computer instructions, allowing for extreme precision and repeatability.
Besides CNC turning, CNC milling is one of the most popular custom CNC machining processes. CNC milling services are used for the majority of machined parts because it can handle a wide variety of irregular geometries. It is also an efficient means of mass production once the setup is complete.
We facilitie contain high-end 3-axis, 4-axis, and 5-axis CNC machining centers, including models from Haas and JingDiao.
Yes. We can use a CNC machine to mill details, features, and text onto parts made using other processes like casting and 3D printing.
The major difference between CNC milling and CNC lathe is in their machining process. CNC milling involves rotating the cutting tools against a stationary bar stock or workpiece. In contrast, a CNC lather works by rotating the bar stock or workpiece against a stationary tool. CNC milling is more suitable for machining irregular and flat surfaces, while CNC lathes work best for cylindrical or conical parts.
we can produce highly complex and intricate rapid prototypes and low-volume production parts. The CNC milling process is suitable for a wide selection of materials for various applications. Our CNC milling service can achieve standard tolerances of +/- 0.05mm. However, tighter tolerances of up to +/- 0.01mm are also possible.
