CNC Machining Finishes:
Machined components can receive a range of finishes to enhance their appearance and properties. These can include anodising, poweder coating, electroplating, polishing and more and these finishes are essential for meeting specific project requirements. At Qimtek, we can help you find the right suppliers who specialise in these finishing processes, ensuring that your components are treated to your exact specifications. For CNC machined components, which require precise and high-quality finishes, the three most common finishes applied are:
- Anodising: Especially for aluminum parts, anodising enhances the corrosion resistance, surface hardness, and wear resistance of the components. It also provides electrical insulation and can be used to add color.
- Powder Coating: This finish involves applying a dry, free-flowing powder onto the machined component, which is then cured under heat to form a hard, protective layer. Powder coating is known for its durability and resistance to chipping, scratching, and corrosion, and offers a wide range of color and texture options.
- Electroplating: This process involves covering the machined component with a thin layer of another metal, such as nickel, chrome, or gold, by using an electric current. Electroplating is used to improve wear resistance, reduce friction, protect against corrosion, increase surface thickness, and enhance aesthetic appeal.
Approvals for Machinists:
UK machine shops pursue various approvals and certifications to uphold quality and industry standards. Common certifications include ISO 9001 for quality management, AS9100 for aerospace, ISO 13485 for medical devices, and ISO 14001 for environmental management.
