A Comprehensive Guide to CNC Turned Parts

Rally Precision is passionate about providing customers with high precision and advanced CNC turning solutions. Rally Precision's highly trained staff guides you through every aspect of CNC turning operation. We make sure our customers make smart choices for their prototype and volume orders. To make it easier for you, here's a complete guide to CNC Turning.

What Is CNC Turning?

CNC turning is one of the many techniques of computer-controlled machining which creates custom CNC turned parts by the rotation of the workpiece. In this process, the workpiece in a cylindrical shape is positioned in a chuck and rotated. While the workpiece is spinning, the fixed cutting tool transforms it into the desired CNC turned parts by removing the material from it. CNC turning can be done on the inside or outside of the workpiece depending on the geometry.

What are the types of CNC turning?

For producing CNC turned parts with diverse styles and geometries, there are many types of CNC turning. Here are some of them:

  • Facing: It is a type of CNC turning in which the cylindrical workpiece is positioned to the center of the machine.
  • Hard Turning: It includes a heat treatment before the turning process and it is best for harder materials, such as brass.
  • Grooving: The cutting tool makes deep furrows in the workpiece to shape it into a certain complexity and shape.

What materials can be used for CNC turned parts?

CNC turning is a highly versatile process capable of working with a wide variety of materials to produce precision parts. This range of materials encompasses numerous metals and plastics, each offering unique characteristics that make them suitable for various applications.


Aluminum: Lightweight and known for its excellent thermal conductivity, aluminum is a popular choice for CNC turned parts. It's easy to machine, and its corrosion resistance makes it suitable for a myriad of industries, including aerospace and automotive.

Brass: Brass is another material favored for its machinability. Its inherent resistance to corrosion and electrical conductivity make brass CNC turned parts perfect for use in electronics, marine applications, and plumbing fixtures.

Stainless Steel: A hardy metal, stainless steel offers high strength and excellent resistance to rust. These qualities make it ideal for parts that need to withstand high-stress environments. Stainless steel CNC turned parts are used extensively in the medical, food processing, and general engineering sectors.

CNC stainless steel turning parts


Polytetrafluoroethylene (PTFE): PTFE is a high-performance plastic known for its non-reactive nature and high melting point. These attributes make it an ideal material for CNC turned parts used in chemical, electrical insulation, and non-stick applications.

Polyoxymethylene (POM): Often used in precision parts, POM offers high stiffness, low friction, and excellent dimensional stability. POM CNC turned parts are used for mechanisms and bearings in automotive and consumer electronics.

Acrylonitrile Butadiene Styrene (ABS): ABS is chosen for its high impact resistance and excellent moldability. ABS CNC turned parts are often used in automotive and electronics industries, as well as in toys manufacturing.

Understanding the Difference Between CNC Turned Parts and CNC Milled Parts

Computer Numerical Control (CNC) technology has revolutionized manufacturing, enabling production of complex and precise parts with high efficiency. Among the various CNC machining processes, turning and milling are two of the most commonly used. While they both utilize CNC technology and can often work with similar materials, the two processes have distinct differences that make them suited for different types of parts.

CNC Turning:

CNC turning involves a bar of material being held in a chuck and rotated (turned) while a tool is fed to the piece to remove material and create the desired shape. The primary movements in CNC turning are rotational, which makes it especially effective for creating cylindrical or round shapes.

Rally Precision-CNC Turning Service-Precision Machining Services

CNC turned parts often have features such as threads, grooves, and tapers. This process is best suited for producing parts like bushings, shafts, and screws, where the primary features go around the axis of the part. The advantage of CNC turning is that it can achieve a smooth surface finish and it can also maintain very tight tolerances. However, its design scope is more limited than milling, as it's primarily used for rotational or symmetrical parts.

CNC Milling:

CNC milling, on the other hand, uses a rotating cutting tool that moves along multiple axes to cut material away from a block or sheet to create the desired shape. Milling machines can move the cutter in different directions, enabling them to create a wider variety of shapes compared to lathes.

Rally Precision-CNC Drilling Service

CNC milled parts can have a vast range of features and geometry. They can have pockets, holes, and varying depths and angles, making it possible to create more complex shapes. This makes CNC milling suitable for parts like brackets, enclosures, and mechanical components. While the surface finish in milling might not be as smooth as in turning, milling offers greater flexibility in terms of the shapes that can be created.

Comparing the Two:

In terms of operation, CNC turning is generally quicker and more efficient for cylindrical or round parts due to its continuous cutting action. Milling, although slower, can achieve a greater variety of shapes and features. Thus, the choice between turning and milling will largely depend on the part geometry.

In terms of materials, both turning and milling can work with a variety of materials, including different types of metals and plastics. However, the selection of the right material can depend on the specific process, as some materials may be more suitable for turning while others for milling.

In terms of precision, both processes can achieve high accuracy and tight tolerances. However, the surface finish can be smoother in CNC turned parts due to the continuous cutting action.

In conclusion, while both CNC turning and CNC milling are essential in modern manufacturing, they have their unique advantages and are used for different types of parts. Understanding these differences can help in choosing the right process for the desired application, ensuring efficient production and high-quality results.

What types of surface treatment are usually applied to CNC turned parts?

CNC turned parts undergo various types of surface treatments to enhance their performance, durability, appearance, or other specific features according to their intended application. Here are some commonly applied surface treatments:

  1. Anodizing: This electrochemical process creates a thin, protective oxide layer on the surface of the part, most often aluminum. The anodized coating offers enhanced corrosion resistance, improved surface hardness, better adhesive base for paints and primers, and a decorative finish with various color options.

  2. Plating: Plating involves coating the part with a thin layer of metal such as gold, silver, nickel, or zinc. This surface treatment method can increase corrosion resistance, enhance electrical conductivity, and provide aesthetic appeal. Electroplating and electroless plating are two primary methods used in this process.

  3. Powder Coating: This is a free-flowing, dry powder application that is cured under heat to form a hard, protective layer. Powder coating offers a uniform, durable, high-quality, and attractive finish. It is resistant to scratches, chipping, abrasions, and corrosion.

  4. CNC machining China manufacturer: metal surface finishing

  5. Passivation: This process, typically used for stainless steel parts, involves removing free iron from the material's surface. It helps in enhancing the natural corrosion-resistant property of stainless steel, thus prolonging the part's lifespan.

  6. Heat Treatment: This process is used to alter the physical (and sometimes chemical) properties of the part. It can improve hardness, ductility, toughness, and stress relief. Common types of heat treatments include annealing, tempering, hardening, and stress relieving.

  7. Polishing: Polishing enhances the visual appeal of the parts while removing surface imperfections, enhancing corrosion resistance and ease of cleaning.

  8. Chemical Film/Conversion Coating: This process is used on aluminum to provide a surface conducive to adhesion of paints and sealants and provides some protection against corrosion.

The choice of surface treatment depends on the base material, the intended application of the part, and the required physical characteristics.
