High-Speed CNC Milling

High-speed CNC milling operates at spindle speeds above 15,000 RPM with high feed rates, reducing cycle times and improving surface finish compared to conventional milling. The process requires high-spindle-speed machines with rigid construction, high-pressure coolant delivery, and advanced CAM strategies for toolpath optimization. Aluminum is the primary material for high-speed milling, but the process is also effective on steel, stainless steel, and engineering plastics. Benefits include reduced cycle times (typically 30-50% faster), improved surface finish (Ra 0.8μm achievable), reduced cutting forces that minimize part deflection, and extended tool life with proper tooling selection. We apply high-speed milling on 3, 4, and 5-axis machines for both prototype and production quantities.

Anodizing

• Clear Anodizing (Type II): Transparent protective layer

• Hard Anodizing (Type III): Thick, wear-resistant coating for moving surfaces

• Color Anodizing: Black, gold, red, blue, and custom colors

• Chromic Acid Anodizing: Thin coating for aerospace fatigue-critical parts

Chemical Finishes

• Chem-Film (Alodine): Conductive corrosion protection for electronics

• Passivation: Surface cleaning and oxide layer stabilization

Coating & Plating

• Powder Coating: Durable polymer finish in any RAL color

• Electroless Nickel Plating: Uniform nickel-phosphorus coating with hardness and corrosion resistance

• PTFE / Teflon Coating: Low-friction, non-stick surface for sliding applications

Mechanical Finishes

• Bead Blasting: Uniform matte texture for prepaint or decorative finish

• Brushing: Directional grain pattern for consumer and architectural parts

• Polishing: High-gloss reflective finish for aesthetic requirements

• Tumbling: Edge deburring and surface smoothing on large quantities

Application Guidelines

• Aerospace exterior: Hard anodizing or chromic acid anodizing

• Medical devices: Passivation or electropolishing

• Consumer visible parts: Brushing + clear anodizing

• High-wear components: Hard anodizing (Type III)

• Electronic applications: Chem-film (Alodine) for conductivity

• Outdoor / marine: Powder coating or e-coating
