CNC turning is a precision machining process used to create accurate cylindrical and concentric components by removing material from rotating stock. The controlled toolpaths deliver stable diameters, clean surface finishes, and consistent dimensional repeatability for both prototypes and production parts.
A spindle rotates the raw material while cutting tools shape external and internal features such as profiles, bores, grooves, and threads. This method ensures stable geometry and predictable accuracy.
The machine executes programmed feeds, speeds, and tool motions to achieve precise dimensions.
Different types of lathes handle different levels of work, from basic turning of round parts to advanced machines that produce very small or complex shapes. Each type helps improve stability, tool control, and accuracy during machining.

Advantages
Powder coating provides a range of benefits, ensuring efficient, high-quality production.
Applications
Powder coating is widely utilized in various industries to produce high-precision parts and components:
We specialize in converting your ideas into high-quality, functional components with unparalleled speed and accuracy. With advanced technology and expert craftsmanship, we create parts that meet the most complex specifications.
Is powder coating more expensive than traditional painting?
While the initial cost of powder coating may be higher than liquid painting, it offers significant long-term cost benefits. The durability of powder coating means that parts require less frequent re-coating, reducing maintenance costs. Additionally, the process is more efficient, and excess powder can be recycled, making it a more cost-effective solution in the long run.
What is the environmental impact of powder coating?
Powder coating is an environmentally friendly option compared to traditional liquid painting. It produces no volatile organic compounds (VOCs) and has minimal environmental impact, as any overspray can be recycled and reused. Additionally, the powder coating process generates less waste because it uses dry powder instead of liquid paint, reducing hazardous disposal needs.
How do you prepare parts for powder coating?
Proper preparation is essential for achieving a high-quality powder-coated finish. Parts must be thoroughly cleaned and degreased to remove any dirt, grease, or oil that could interfere with adhesion. We also sandblast or chemically etch the surface to create a rough texture that helps the powder coat bond more effectively. This process ensures a smooth, durable finish that lasts.
Can powder coating be applied to complex shapes?
Yes, powder coating can be applied to complex shapes, but it requires careful preparation and expertise. At Yicen Precision, we have the equipment and experience to powder coat parts with intricate geometries. We use advanced spraying techniques to ensure that all surfaces, including hard-to-reach areas, receive an even coating. This ensures a consistent finish on all parts, regardless of shape or size.
How long does powder coating take to cure?
The curing time for powder coating depends on the material, the thickness of the coating, and the curing temperature. Generally, powder coating is cured in an oven at temperatures ranging from 180°C to 200°C (350°F to 400°F) for about 10-20 minutes. The curing process ensures that the coating bonds tightly to the surface, resulting in a smooth and durable finish.
How durable is powder coating?
Powder coating is highly durable and provides excellent protection against scratches, corrosion, fading, and chipping. It forms a strong bond with the surface, making it ideal for parts exposed to harsh environments, such as automotive components, outdoor furniture, and industrial machinery. The cured finish is resistant to chemicals, moisture, and UV rays, making it a long-lasting option for many applications.
What colors are available for powder coating?
Powder coating offers a vast array of colors and finishes, including matte, glossy, satin, and textured options. We offer standard colors like black, white, and grey, as well as custom color matching to fit your specific needs. Whether you’re looking for a bright finish or a more subtle, industrial look, we can help you choose the right color and finish for your project.
What are the advantages of powder coating over traditional liquid paint?
Powder coating offers several advantages over traditional liquid paint, including better durability, resistance to scratches, chips, and fading, and a more uniform finish. It also provides a thicker coating without running or sagging. Powder coating is environmentally friendly as it produces fewer volatile organic compounds (VOCs) and reduces waste due to overspray that can be recycled.
