Thin-Walled Parts
Thin-walled parts refer to complex structural parts with a wall thickness to length or diameter ratio of less than 1/10, usually with a thickness of less than 1.5MM, and are mainly made of aluminum, titanium alloy, and copper. Typical parts include fuselage skins in the aerospace field, automotive covers, precision housings of electronic products, and lightweight components in medical devices.
Core Process Advantages
Precision Deformation Control: By optimizing cutting parameters (high speed and low cutting depth, symmetrical layered milling) and clamping processes (elastic clamps/vacuum adsorption), the shape and position errors caused by cutting force, thermal deformation and vibration are effectively suppressed to ensure ±0.025mm level accuracy.
Efficient Cutting Technology: The combination of D6 rough milling cutter (3500r/min) and D4 fine milling cutter (10000r/min) is used, combined with the down-milling strategy and sharp blade design to significantly reduce cutting force and improve surface finish.
Heat Treatment Strengthening: Pre-aging treatment is implemented according to material properties to eliminate residual stress and improve the rigidity and dimensional stability of thin-walled parts.
Tool and Process Adaptation
- Rough machining: D6 flat-bottom end mill, axial cutting depth of 0.6mm, feed 2000mm/min, quickly remove the allowance and retain 1mm finishing allowance.
- Finishing: D4 milling cutter (10000r/min), radial cutting depth of 0.5D (tool diameter), with symmetrical tool path to ensure balanced force around the thin wall.
Application Industries and Solutions
Widely serve in aerospace (wing structural parts), new energy vehicles (battery housings), consumer electronics (5G base station heat sinks) and other fields to solve customer pain points:
Complex Surface Forming: rounded surfaces (below R0.5) are milled once to meet the standards, reducing secondary polishing.
Ultra-Thin Wall Processing: 2.2mm thick copper parts achieve 20mm height deformation-free cutting.
Batch Consistency: Through the automated detection system (three-coordinate + laser scanning), the tolerance of thousands of products is ensured to be ≤0.01mm.
Core Competitiveness of the Factory
- Technical Barriers: mastering proprietary processes such as high-speed milling (Vf=1m/min), super-hard coating tools (TiAlN coating life increased by 3 times).
- Equipment Configuration: five-axis linkage machining center (positioning accuracy ±2μm), constant temperature workshop (20±0.5℃) to ensure precision machining environment.
