AN-Prototype Factory

Our Powerful Facilities


CNC Turning Services With Tolerances Up to ±0.001mm

AN-Prototype is committed to providing the most intimate precision CNC turning services for new product developers to complete any project. Our climate-controlled workshop uses CNC lathes and imported cutting tools from the US or Japan. CNC turning centers have the ability to create complex and dimension-critical custom high-quality metal or plastic parts for rapid prototyping or low-volume manufacturing.

What Is CNC Turning?

CNC turning is the process of removing material from a rotating workpiece along a linear path using tools on a CNC lathe. From a simple point of view, the main elements involved in this process are the rotating spindle that clamps the workpiece and the cutting tool mounted on the turret. Unlike CNC milling, the cutting tool in CNC turning does not rotate.

When CNC lathes use fine cutting tools, the surface finish of turned parts is very good and does not require any post-processing. Turning is virtually the only practical way to create internal and external threads, slotted holes, tapers, annular grooves, and many other features with essentially circular cross-sections.

Why Choose CNC Turning Services?

CNC turning is an ideal process for manufacturing circular or cylindrical parts. CNC lathes can manufacture these parts quickly and accurately with excellent repeatability.

CNC lathes have a high degree of automation and are highly scalable, which allows CNC turning to be adapted to low-volume and high-volume production without too much cost.

Multi-axis CNC turning centers and mill-turn lathes allow multiple operations and multi-step machining operations to be performed on a single machine, cost-effectively creating complex geometries.

Available Operations of AN-Prototype CNC Turning Services

In addition to turning, CNC lathes can perform a variety of other machining operations; including: surface of revolution, external turning, internal turning, taper turning, parting off, facing, boring, reaming, drilling, knurling, threading, Grooving etc.



The tool is fed radially into the other end in the rotating workpiece to form a flat surface on the end.


Taper Turning

Taper turning is the most economical way to manufacture tapered shafts. In the external turning process of the tool, the diameter of the cutting workpiece changes gradually.



Drilling is performed on a lathe by feeding a drill bit along its axis into a rotating workpiece. Reaming can be done in a similar manner.

Contour Turning

Form Turning

A shaped tool cuts the workpiece radially, thereby imparting shape to the workpiece, also known as forming.



The tool cuts an angle at the corner of the part, creating what is known as a "chamfer".



Special tools work on the surface of the workpiece, creating a process with a regular crossing pattern on the part. It is a metal forming operation.



A pointed tool is fed linearly at a high effective feed rate across the outer surface of the rotating workpiece in a direction parallel to the axis of rotation to create threads in the cylinder.



A single-point tool is fed linearly, parallel to the axis of rotation, on the inside diameter of an existing hole in the part.



The tool is fed radially into the rotating workpiece at a point along the workpiece to cut to the end of the part. This operation is sometimes called detaching.


Contour Turning

Instead feed with the tool in a straight line parallel to the axis of rotation. The tool follows the profile feed of the curve, creating the profile shape in the turned part.

Turned Parts Specifications

CNC Turning Materials

CNC turned parts can be made from a variety of metal and plastic materials. For example, metals include aluminum, steel, stainless steel, brass, copper, magnesium alloys, titanium alloys, etc., and plastics ABS, POM, PEEK, acrylic, nylon, etc.Note that some tool steels may be too hard to cut on a lathe or mill, or will require special handling and longer manufacturing times. Soft elastomers or plastics may also fail to turn because they cannot stay in place or change shape under the pressure of a cutting tool.

CNC Turning Metal

CNC Turning Metal Materials

Aluminum is the most commonly used material in CNC turning metal materials, and it can also be used to process metals such as magnesium, steel, stainless steel, brass, copper, bronze, titanium and nickel alloys. CNC turned metal parts can be manufactured with high strength and precision as well as excellent surface finish.

CNC Turning Plastic

CNC Turning Plastic Materials

Precision CNC turning machining is typically done on metals, but CNC turning services are also available for plastic parts. Common CNC turned materials include Nylon, Polycarbonate, ABS, POM, PP, PMMA, PTFE, PEI, PEEK, allowing for more accurate custom parts than 3D printing.

Available Surface Finishes After CNC Turning


As Machined

This is the most economical and quick surface preparation option, the surface of the turned part will leave visible machining marks. The surface finish is equivalent to 3.2RA μm, and can reach 0.1RA μm for special requirements.



Anodizing is commonly used on aluminum parts, but also on titanium parts. The surface of the anodized part will absorb a layer of hard non-conductive ceramic coating to improve wear resistance and retain the metal texture and luster to improve the visual effect.



Sandblasting is the process of blasting abrasives onto the surface of a part under high pressure to achieve a matte finish. Sandblasted metal parts have a satin-textured or matte finish to eliminate post-processing marks.


Powder Coating

Powder coating is a common finishing option that utilizes a high-pressure spray gun to apply a solid, colorful polymer coating to the surface of a part, improving the wear and corrosion resistance of the part.



Electropolishing is the inverse of electroplating, where a chemical solution is used to simplify the metal surface on a microscopic level. After electropolishing, metal parts can be shinier and reduce surface roughness.



Passivation is a method to transform the surface of parts into a state that is not easily oxidized, and to delay the corrosion rate. Often used in stainless steel parts.

Black Oxide

Black Oxide

Black oxide is a chemical conversion coating produced by the chemical reaction of iron and oxide salts in a black oxide solution. Blackened and oxidized parts can improve corrosion resistance.



Polishing is the process of making the surface of parts smoother and smoother through physical friction treatment, which is often used to prevent corrosion and remove oxidation.
