Aerospace Industry

• Material Selection & Machining: Titanium alloys, high-temperature alloys (e.g., Inconel series) and high-strength stainless steel are preferred. These materials undergo strict smelting, rolling and heat treatment to ensure uniform composition and stable mechanical properties, achieving both lightweight design and high strength – reducing overall equipment weight while withstanding high loads and impacts during flight. Special tools and low-speed cutting are adopted to overcome difficult machinability and cracking risks, minimizing processing stress.
• Precision Control: Dimensional tolerances are strictly controlled within ±0.005~±0.01 mm. Thread precision fully complies with the AS9100 aerospace quality management system, including thread form, pitch error, flank angle tolerance and other key indicators. High-precision CNC lathes, grinders and thread machining equipment are used, combined with coordinate measuring machines (CMM) and thread profilometers, to realize traceable precision control in each process and eliminate dimensional deviations.
• Performance Assurance: Products must withstand extreme conditions including high temperatures (over 600°C in engine zones), low temperatures (below -50°C at high altitudes) and high corrosion (high-altitude atmosphere, fuel media), with excellent oxidation resistance, fatigue strength and corrosion resistance. Vacuum heat treatment, surface strengthening (nitriding, shot peening, etc.) are applied to enhance performance. A full-process traceability system is established, with a unique traceability code for each batch from raw material procurement, processing to finished product inspection, enabling rapid fault location.
• Structural Design & Customized Production: Special structures such as profiled heads, countersunk heads and hexagon socket heads are commonly used, with anti-loosening designs including lock washers and thread adhesive grooves. Some products require custom thread specifications for specific applications. Profiled structures are precisely manufactured per drawings to ensure dimensional consistency; thread processes are optimized to prevent thread slipping and stripping, meeting assembly precision requirements of aerospace equipment.

General Core Characteristics of CNC Machined Screws

• Ultra-high precision: Standard tolerance ±0.01 mm, precision version up to ±0.001 mm, with accurate, clearance-free thread fit.
• High consistency: Program-controlled, with uniform dimensions, geometric form and surface quality in mass production.
• Flexible customization: No mold required; fast switching for non-standard pitches, special heads, multi-step profiles and special slot types.
• Wide material compatibility: Capable of machining stainless steel, titanium alloy, aluminum alloy, copper alloy, high-temperature alloy, etc.
• Flexible efficiency & batch size: Suitable for small-batch prototyping and medium-batch customization, with fast switching between single parts and multi-variety production.
