Our CNC Turning Services

In a CNC machining service, CNC turning is often required for a specific category of metal or plastic parts. CNC turning is one of many CNC machining processes in which workpieces rotate at high speed in a chuck to manufacture metal and plastic turned parts. Unlike CNC milling, cutting tools do not rotate.

CNC turning materials can be metal, including aluminum, magnesium, steel, stainless steel, brass, copper, bronze, titanium and nickel alloys; It can also be plastics, such as nylon, polycarbonate, ABS, POM, PP, PMMA, PTFE, PEI, PEEK, etc. CNC lathes are also called lathes.

Advantages of CNC turning

1. Cylindrical parts
CNC lathes turning machines are ideal for manufacturing round or cylindrical parts. Lathes can manufacture these parts quickly, accurately, and with excellent repeatability.

2. Process range
Although typically used for parts of a certain shape, CNC turning can still be used to make a variety of cuts, including drilling, boring, threading, and knurling.

3. Professional quality
Our precision CNC turning lathes provide low-cost parts for simple and complex cylindrical geometries. With advanced technologies and expert technicians, we produce high-quality custom prototypes and end-use production parts.

CNC turning plastics

While precision machining is typically used for metals, we can also provide CNC turning services for plastic parts. Materials available for CNC turning include nylon, polycarbonate, ABS, POM, PP, PMMA, PTFE, PEI, PEEK, providing more accurate parts than 3D printing.

CNC turning metals

Aluminum machining is a key part of our services catalog, but CNC turning can also be used to process metals like magnesium, steel, stainless steel, brass, copper, bronze, titanium and nickel alloy. CNC turning is commonly used for mechanical and aspect components, which are often made from aluminum, the most machinable metal. Aluminum parts can be made with high strength and accuracy, as well as a superior surface finish.

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 turned within minutes or even seconds by optimizing the tool paths and using special cutting tools. Our automation setup for CNC turning 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 turning 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 cylindrical shapes

CNC turning is ideal for creating cylindrical shapes or parts that are symmetrical near their axis, for example, a chess pawn, bolts, rivets, ball bearings, and washers. CNC turning machines also allow cutting operations to occur along 3-, 4-, or 5-axis, allowing you to perform taper turning, knurling, threading, and parting, among other operations. This subtractive manufacturing process is particularly suited for rapid prototyping and low-volume production.

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 turning is a particular form of precision machining in which a cutter removes material by making contact with the spinning workpiece. The movement of the machinery is controlled by computer instructions, allowing for extreme precision and repeatability. Turning is different to CNC milling, in which the cutting tool rotates and is directed from multiple angles at the workpiece, which is usually stationary. Because CNC turning involves rotating the workpiece in a chuck, it is generally used to create round or tubular shapes, achieving far more accurate rounded surfaces than would be possible with CNC milling or other processes. The tooling that is used with a CNC lathe machine is mounted to a turret. This component is programmed to make certain movements and remove material from raw materials until the desired 3D model is formed. Like CNC milling, CNC turning can be used for the rapid manufacture of either prototypes or end-use parts.
The CNC turning process is mostly ideal for cylindrical-shaped raw materials. However, several manufacturers also use it for hexagonal and square-shaped workpieces. It is a popular method for making machine parts for microfluidic tools, signage components, surgical instruments, automotive frames, and aerospace parts.
We can turn parts with diameters ranging from 0.5mm to 65mm for stock bars. Our turning capabilities can reach up to 3000 mm for billets.
Yes, our CNC turning services include plastic parts manufacturing. We can produce small or large batch prototypes and production parts from various engineering-grade plastics. Choose from our extensive range of plastic materials and upload your design file to get custom plastic components.
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.
