What is CNC turning

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 part

How CNC Turning Works

CNC turning (also known as CNC lathes) is a subtractive manufacturing process in which a stationary cutting tool removes material by making contact with the spinning workpiece to create the desired shape.

During processing, a blank bar of stock material is held in the chuck of the spindle and rotated with the spindle. Extreme precision and repeatability can be achieved under the control of computer instructions for the movement of the machinery.

When CNC turning rotates the workpiece in a chuck, it' s generally to create round or tubular shapes and achieve far more accurate rounded surfaces than CNC milling or other machining processes.

    The main vital components of a CNC turning center

    Chuck: Fixes the bar of stock material for machining

    Spindle: Rotates the chuck across axes for material forming.

    Turret: Moves the stock bar in line with the computer-aided manufacturing (CAM) blueprint or

    computer-aided design (CAD).

    Interface: Provides options for the operator to control and use the turning centers.

    The necessary steps for an operator

    Upload CAD or CAM files

    Store and secure specified rods of material in the chuck.

    Start the machining process through the interface or control panel.

    Make sure the coordination between the chuck, turret, and spindle.

    After the process, the operator will evaluate the component to make sure it is defect-free.

Advantages of CNC Turning

  • Cylindrical Parts

    CNC lathe machines also referred to as live tooling lathes, are perfect for creating any symmetrical cylindrical or spherical parts with high accuracy and excellent repeatability at a high speed.

  • Process Range

    Although typically used for specific shapes of parts, CNC turning can still be used for various cutting, such as drilling, boring, threading, and knurling.

  • Accuracy

    The machine can obey strict measurements and eliminate the waste of natural human errors by integrating CAD or CAM files into the process, which may help to improve the financial situation, productivity, etc.

  • Flexibility

    CNC turning centers have great flexibility for a variety of applications since they offer a range of dimensional capabilities. For example, our turning centers are equipped in 18 to 0.5 inches in diameter to meet nearly all needs of our customers.

  • Repeatability

    CNC lathes provide excellent repeatability by producing product batches with unmatched accuracy, allowing your business to maximize output and reduce losses.

  • Efficient

    CNC turning machining parts can cut round parts at the fastest speed, meet your original expectations, make your parts life like, and save time and cost.

CNC Turning FAQs

  • Q

    What is CNC Turning?


    Turning involves a process where CNC lathes cut the bar of stock material into circular shapes. The workpiece is placed in the lathe and rotated while the tool removes the material until only the desired shape is left.

    Turning is an ideal choice for producing cylindrical parts, mainly using round bar stock, but square and hexagonal ones can also be used.

  • Q

    What parts can be produced by CNC turning?


    CNC turning is a method for making symmetrical cylindrical parts. Typical examples are shafts, gears, knobs, tubes, etc. CNC turned parts are usually applied to various applications and industries like aerospace, medical, automotive, and other industries.

  • Q

    How rough CNC turning differs from finished CNC turning?


    Rough CNC turning brings the workpiece close to the desired shape by removing as much material as possible without focusing on precision and surface finish, while finish CNC turning produces the required accuracy and smoothness.

  • Q

    How CNC turning centers differ from CNC lathes?


    CNC lathes are usually two-axis machines with only one spindle. Their production capacity is not high, and there is usually no protective casing around the machine. A CNC turning center is a more advanced version of a CNC lathe, with up to 5 axes and a more general cutting capacity. They also provide the ability to produce larger volumes, often integrating milling, drilling, and other functions.

  • Q

    What parts can CNC turning make?


    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.

  • Q

    What is your maximum diameter capacity for turned 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.

  • Q

    Can you produce plastic turned parts?


    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.

  • Q

    Can you produce plastic turned parts?


    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.

  • Q

    What’s the difference between CNC milling and CNC lathe?


    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 latter 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.
