Material & Finish Options

Material Selection for Horizontal CNC Machining: Aluminum, Steel, Titanium & Anodizing
Material selection is a critical engineering decision that directly determines the performance, cost, and manufacturability of precision components. At Wuxi Lead Precision Machinery, our horizontal CNC machining centers excel with challenging materials due to their superior rigidity, thermal stability, and multi-axis capabilities. Understanding the unique properties and machining characteristics of Aluminum, Steel, and Titanium ensures optimal part functionality and production efficiency. The choice must align with the component’s mechanical requirements, environmental exposure, and post-processing needs like anodizing.
Aluminum alloys, particularly 6061-T6 and 7075-T6, are industry standards for lightweight, high-strength applications requiring excellent machinability and thermal conductivity. Their low density reduces inertia in moving parts, while natural corrosion resistance suits aerospace and automotive housings. Horizontal machining leverages aluminum’s softness for high-speed cutting and complex geometries, though proper chip evacuation is essential to prevent built-up edge. Steel variants like 4140 alloy steel and 304/316 stainless offer superior strength, wear resistance, and structural integrity for tooling, shafts, and high-load components. Machining steel demands robust tooling and precise coolant management to handle higher cutting forces and heat generation. Stainless grades require attention to work hardening but deliver exceptional corrosion resistance for medical or marine environments.
Titanium alloys, notably Grade 5 (Ti-6Al-4V), present the ultimate challenge with exceptional strength-to-weight ratio, biocompatibility, and extreme corrosion resistance. However, titanium’s low thermal conductivity causes heat concentration at the cutting edge, demanding slower speeds, rigid setups, and specialized tool geometries to avoid work hardening or tool failure. Our horizontal CNC platforms mitigate these issues through consistent thermal control and vibration damping, making titanium viable for critical aerospace and medical implants.
Anodizing is the premier surface finish for aluminum components, enhancing corrosion resistance, wear properties, and aesthetic appeal. Type II (sulfuric acid) anodizing provides standard decorative and protective layers, while Type III (hard coat) delivers thicker, harder surfaces for severe wear applications. Achieving uniform anodizing requires meticulous pre-machining surface preparation and tight dimensional control during CNC processing to account for the oxide layer’s growth.
Key material properties for horizontal CNC machining are summarized below:
| Material | Common Grades | Tensile Strength (MPa) | Machinability Index | Key Horizontal Machining Advantages |
|---|---|---|---|---|
| Aluminum | 6061-T6, 7075-T6 | 310-570 | 150-200 | High-speed cutting, excellent chip flow, thermal stability for thin walls |
| Carbon/Alloy Steel | 4140, A36 | 415-1000 | 50-70 | Rigidity handles high cutting forces, precision for tight-tolerance shafts |
| Stainless Steel | 304, 316 | 515-690 | 40-45 | Vibration damping counters work hardening, consistent coolant delivery |
| Titanium | Ti-6Al-4V (Gr5) | 880-950 | 22-30 | Thermal stability prevents heat buildup, rigid setup minimizes deflection |
