CNC machining enables high-precision, large-scale production in automotive component manufacturing. It is widely used in core parts such as engine cylinder blocks (flatness ≤0.02mm), turbocharger impellers (blade thickness 0.3mm ±0.005mm), and transmission gears (tooth profile accuracy DIN 5 grade).
Advanced Technologies:
Five-axis machining allows for the processing of complex curved aluminum alloy suspension arms, reducing weight by 30% while maintaining strength.
Turn-mill combined processing ensures the one-piece formation of brake calipers, achieving a coaxiality of ≤0.01mm.
New Energy Applications:
CNC precision machining enhances the manufacturing of motor housings (roundness 0.008mm) and battery module heat dissipation plates (flatness 0.015mm).
Processing efficiency improves by 40% compared to traditional methods, with a product yield rate of 99.6%, supporting the lightweight and electrification transformation of automobiles.
This drives the industry's shift toward high reliability and intelligent manufacturing.
Materials and processes: Mainly use lightweight and high-strength aluminum alloy (such as 6061/7075) or engineering plastics, use five-axis CNC technology to achieve ±0.005mm ultra-high precision processing, and complete complex structures (such as battery trays and brackets) in one clamping.
Key control: Focus on ensuring dimensional tolerance, structural strength and heat dissipation/insulation performance to ensure battery pack safety and stability; strictly control quality through CMM online detection and material traceability.
Mass production adaptation: Support rapid prototyping (7-day delivery) to mass production (monthly production of more than 100,000 pieces), combine CAD/CAM to optimize tool paths, reduce scrap rate and shorten cycle time.
