High Precision CNC Machining Aluminum Parts Milling Aluminum Alloy Material
Metal Accessories CNC Machining Turning Parts
CNC turning is a manufacturing process that involves securing a blank on a rotating chuck and
using stationary cutting tools to remove material.
This method is particularly suitable for creating parts with symmetrical features along their
central axis.
Turned components are usually manufactured more efficiently and cost-effectively compared to
milled parts.
Product Details
The turning process primarily involves the machining of various metals.
These metals encompass a wide range of materials, including alloy steel, carbon steel, cast iron,
stainless steel, aluminum, copper, magnesium, and zinc.
Nevertheless, it is essential to note that the turning process is not limited to metals alone;
it can also be applied to plastic components and a diverse array of materials such as ceramics,
composites, thermoplastics, and thermosetting materials.

FAQ's
1. Is CNC turning expensive?
The cost of CNC turning can vary depending on factors such as part complexity, material selection,
machine setup, and volume of production, making it difficult to provide a definitive answer without
specific details.
2. CNC Turning Tolerances
Our standard tolerance for CNC turned parts is +/- 0.005 inches. However, in certain cases,
we may be able to achieve even tighter tolerances, depending on the specific geometry of your
parts and the tooling used.
If your project demands a tighter tolerance than our standard +/- 0.005 inches, please inform us
during the quoting stage. Our team will thoroughly evaluate your requirements and provide
guidance on available options.
3. Advantages of CNC Turning
1. Economical for both short and long runs
2. High dimensional tolerances are possible
3. Smooth finishes can be achieved
4. Secondary Surface Finishing in CNC Turning
CNC turning often involves various secondary finishing processes to ensure the desired surface
quality of metal parts after the machining is complete. These secondary finishing services may
include:
1. Deburring: Removing sharp edges or burrs from the machined part.
2. Grinding and Polishing: Enhancing the surface finish of the metal to achieve smoother textures
and improved appearance.
3. Anodizing and Plating: Enhancing the metal's strength, wear resistance, and corrosion resistance.
4. Painting and Powder Coating: Adding color and providing additional protection for metal parts.
These secondary finishing processes are essential to achieve the desired aesthetics, functionality,
and performance of CNC turned components.
