CNC Milling
New Materials and Surface Treatments Now Available!
Including Annealed Stainless Steels & Hard Anodize

Starting October 6, 2024, meviy’s CNC Milling service will introduce new annealed stainless steels and three types of surface treatments. Custom machined parts requiring surface finishes, such as low temperature black chrome, hard anodizing, and phosphate coating, can be efficiently processed from milling to surface treatment all in one place via meviy. Additionally, as of October 15, meviy offers AI-powered instant quoting for gold and red anodizing, which was previously limited to manual quotes. Now, you can quickly obtain pricing and delivery times for your custom parts with finishes.

• What is Annealing?

  Also known as “normalizing,” annealing is a heat treatment process used to soften materials and achieve uniform microstructure through slow cooling. This method effectively removes residual stresses that can cause warping or bending during machining.

303 Stainless Steel (annealed)

• Features
  • Heat Treatment Process: Reheating to the crystallization temperature followed by slow cooling eliminates internal stresses and achieves material softening, resulting in enhanced ductility.
  • Stability in Tolerances: Compared to standard materials, this process minimizes distortion, ensuring stable tolerances after machining.
  • Machinability: Among stainless steels, this material offers superior machinability, making it ideal for complex designs.

• Applications
  • Automotive equipment, chemical processing equipment, high-precision parts, household items, architectural elements

304 Stainless Steel (annealed)

• Features
  • Heat Treatment Process: Reheating to the crystallization temperature followed by slow cooling eliminates internal stresses and achieves material softening, resulting in enhanced ductility.
  • Stability in Tolerances: Compared to standard materials, this process minimizes distortion, ensuring stable tolerances after machining.
  • Excellent Weldability: The annealed 304 stainless steel offers superior weldability, making it suitable for various applications.

• Applications
  • Automotive equipment, chemical processing equipment, high-precision parts, household items, architectural elements

Hard Anodize

• Features
  • Durable Coating: Aluminum treated with hard anodizing achieves a robust film that provides excellent wear resistance.
    *The appearance may vary depending on the material and coating thickness.
• Applications
  • Automotive equipment, railway systems, aerospace components, medical devices

Phosphate Coating

• Features
  • Corrosion and Wear Resistance: Phosphate coating offers excellent protection against rust and wear.
  • High Adhesion: Its strong adhesion makes it ideal for use as a pre-treatment before painting.
    * The treatment uses either zinc phosphate or manganese phosphate, resulting in variations in color and appearance. Please note that the selection of the treatment solution is not available.
• Applications
  • Automotive equipment, industrial machinery, robotics, parts prior to painting

Low Temperature Black Chrome Plating

• Features
  • Corrosion Protection: This surface treatment provides excellent rust and Long-lasting corrosion resistance.
  • Uniform Thin Coating: With a film thickness of approximately 2μ, it allows for high machining precision, even on treated surfaces.
  • Matte Black Finish: The matte black color helps prevent glare and reflection.
• Applications
  • Semiconductor equipment, medical devices, optical instruments, architectural elements
