Custom CNC Turning Service
High Precision Turning Service for both metals and plastics.
What is CNC Turning?
CNC turning is a relatively quick and versatile process of using a computer numerical control to turn a piece of material, typically metal, into a finished product. It can be used to create a wide variety of shapes and sizes, from small to medium sized parts with a high degree of accuracy. And it’s widely used for a variety of applications, such as creating parts for machines or automobiles.
How CNC Turning works?
CNC turning is a common machining process used to produce parts with cylindrical geometries. The process involves holding a workpiece in a lathe and rotating it while cutting tools remove material to shape the desired geometry.
Most CNC turning operations are performed on metals, but the process can also be used for plastics.
Types of Turning Lathes
There are three main types of turning lathes: engine lathes, turret lathes and automatic lathes.
Engine lathes are the most common type of lathe. They are used to create cylindrical parts with a high degree of accuracy. Engine lathes have a headstock that is mounted on a bed. The headstock has a spindle that the workpiece is mounted on. The headstock also has a tailstock that is used to support the workpiece. The workpiece is rotated by the spindle and is fed through the headstock and tailstock by a carriage.
Turret lathes are used to create larger parts with more complex shapes.They have a turret that is mounted on a bed. The turret has a spindle that the workpiece is mounted on. The turret also has a tailstock that is used to support the workpiece. The workpiece is rotated by the spindle and is fed through the turret and tailstock by a carriage.
Automatic lathes are used to create small, intricate parts with a high degree of accuracy. Automatic lathes have a spindle that the workpiece is mounted on. The spindle is mounted on a carriage that is fed through a headstock and tailstock. The workpiece is rotated by the spindle and is fed through the headstock and tailstock by the carriage.
At Shanghai Elue, we have 10 sets automatic lathes and they run 24hours non-stop.

Applications of CNC Turning
Shanghai Elue is an expert for custom CNC turning services, and our turning parts are widely used in many sectors like medical, electronics, automotive, high-tech, machinery, semiconductor, aerospace, etc.
Advantages of CNC Turning
CNC Turning machines are able to produce parts with extremely tight tolerances, which is often critical in the manufacture of precision components.
CNC Machines can produce parts much more quickly than traditional methods. This increased productivity can lead to significant cost savings.
With CNC turning, it is possible to quickly and easily change the design of a part without having to make expensive tooling changes.
CNC turning machines offer a high degree of repeatability. This is due to the fact that the same process is carried out each time the machine is operated. The only thing that changes is the position of the workpiece. This means that there is very little variation in the end product.
CNC turning is a much safer process than manual turning. This is because the operator is not in direct contact with the cutting tools. There is also less chance of human error when using a CNC machine.
CNC turning machines can create products at a fraction of the time it would take to produce those same products manually.
CNC turning also eliminates much of the wasted material that is inherent in manual machining processes.
Different Operations involved in CNC Turning
Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helix toolpath by moving more or less linearly while the workpiece rotates.
Facing is the process of machining surfaces that are at right angles to the axis of the workpiece. Facing can be performed on the outer diameter of a cylindrical workpiece or on inner diameters (boring). The face of a workpiece may be machined flat, at an angle, concave, or convex.
Threading is the process of creating a screw thread. There are many methods of generating threads, including subtractive methods (many kinds of thread cutting and grinding, as detailed below); deformative or transformative methods (rolling and forming; molding and casting); additive methods (such as 3D printing).
Grooving is the process of machining a groove into a workpiece. Grooves are generally used to accommodate round operating elements, such as splines or tenons, by providing a coaxial bearing surface.Drilling is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials.
Drilling & Tapping
Drilling & Tapping is a process where holes are drilled into a workpiece and threads are cut into the walls of the hole. This is done using a combination of drilling and tapping operations. The drill bit is used to create a hole of the appropriate size, while the tap cuts threads into the side of the hole.
Reaming is a finishing operation performed with a multi-point cutting tool. The reamer is used to enlarge the size of an existing hole to a precise diameter. This process is typically used when the tolerances are very tight and a smooth finish is required.
CNC Turning Frequently Asked Questions
For all machined parts, whether CNC Turning or milling, they have got a wide selection of surface finishes including: as-machined standard finish(Ra1.6-3.2), Smooth finish Ra0.8, Anodizing (including Type II mainly for cosmetic use and Type III hardcoating), Polishing, Beadblasting, Powder coating, Painting, Black oxide, Plating, Brushing, etc. If you can’t decide what surface finishes to choose from, our engineering will guide you in the right direction depending on the application and materials of your parts.
If not specially requested, we’ll make it done as per the general tolerance standard DIN ISO 2768-2. But If you have the right tolerance on the drawings, we’ll make it done exactly as per requested. Be sure to provide pdf files if you need some special tolerances.
CNC turning is a good choice for all rotary parts with high precison or complex shapes, from rapid prototyping, small batches volume, to even mass production orders. at Shanghai Elue, the maximum parts OD for our turning lathes is 2.0″, and the OD can be as small as 0.1″. If you can’t decide, please feel free to upload your drawings to ask.
To make it simple, CNC turning is applied for cylindrical parts, and the workpiece will rotate to cut while the tools keep still; for CNC milling, the tools will rotate to cut the workpiece, it’s a very useful machining process for more complex parts.
