High Precision CNC Metal Turning Services

一、Material Processing Characteristics of CNC Turning

Aluminum Alloy Processing

Aluminum alloys feature low density and excellent thermal conductivity. They can be machined at high speeds (3000-8000 rpm) with large feed rates, achieving surface roughness below Ra 1.6 μm without requiring additional polishing. Commonly used for electronic enclosures and automotive lightweight components. Complex parts may undergo CNC turning followed by 5-Axis CNC Milling for intricate features, often paired with Sheet Metal Bending for structural frames.

Titanium Alloy Processing

Titanium alloys exhibit high strength and challenging machinability, prone to work hardening. Carbide tools must be selected, with controlled cutting speeds (80-150 m/min) and depths (≤0.5 mm), supplemented by high-pressure cooling. Suitable for aerospace engine blade shafts, medical implants, etc. Post-machining often incorporates Precision Laser Cutting for micro-hole processing, followed by heat treatment within metal fabrication services.

Engineering Plastics Processing

For materials like nylon and POM, excessive cutting temperatures must be avoided. Typically employ low speeds (500-1500 rpm), moderate feed rates, and sharp high-speed steel tools. Suitable for food machinery components and electronic insulators. Certain parts require assembly with metal mesh covers processed via Laser Cutting Service. Processing standards align with CNC Milling procedures for plastic components.
