CNC Revolutionizes Manufacturing in Medical and Aerospace Sectors

2. Multi-axis interpolation machining of complex geometries

Medical: Dentures require 360° circular engraving. CNC systems use programmed commands to control machine tools, employing four-axis distributed control to achieve smooth surface transitions and avoid corner velocity discontinuities.

Aerospace: Five-Axis Machine tools can complete the machining of the three-dimensional curved surfaces of scroll blades in a single operation, reducing clamping errors. For example, titanium alloy aerospace structural parts utilize five-axis collaboration to address deformation control issues.

3. Intelligent process integration

Seamless integration of CAD/CAM software and CNC systems: Medical dental engraving machines achieve 24-hour delivery of dentures through a "scanning modeling → program modification → CAM tool path generation → CNC engraving" process. In the aerospace sector, AI can be incorporated to optimize machining paths.

II. Medical Manufacturing: From Mass-produced Dentures to Minimally Invasive Surgery

1. Denture Processing: Balancing Efficiency and Personalization

Traditional dentures require multiple manual adjustments, taking one to two weeks to complete. In contrast, CNC dental engraving machines carve directly from zirconia blocks, shortening the process to just one day and adapting to the individual patient's tooth shape. CNC technology uses curve fitting to transform small line segments into smooth curves, avoiding step-like patterns on the denture surface and improving occlusal comfort.

2. Precision Manufacturing of Minimally Invasive Surgical Instruments

Swiss SPHINX micro-milling cutters (minimum diameter 0.02mm) are used to process neurosurgical catheters, orthopedic implants, and are widely used in eyewear accessories and medical equipment.

III. Aerospace: Manufacturing Breakthroughs Under Extreme Conditions

1. Core Components of Aircraft Engines

Challenges: Scroll blades must balance thin walls (1.8mm), high precision (±3 microns), and dynamic balance (<0.09g·mm).

CNC Solution: 5-axis machining centers process SUS304 stainless steel in stages, combined with an online measurement system for real-time deformation compensation to avoid dimensional deviations after heat treatment.

2. Localization of Large Aircraft Structural Parts

Kede CNC has partnered with aviation companies to establish a "Large Aircraft Process Verification and Testing Base." This base focuses on Precision Machining of complex structures for domestically produced large aircraft, such as the C919/C929, and large UAVs. It strives to overcome bottlenecks in transitioning core components from the laboratory to mass production, explore new mechanisms, and promote a virtuous cycle between technological and industrial innovation. Addressing challenges such as titanium alloy frame plates and long shaft deep-hole components, domestically produced 5-axis machine tools are used to verify material compatibility, driving the upgrade of C919/C929 components from "usable" to "highly usable."

3. Composite Material Processing and Green Manufacturing

The emergence of the "dark factory" marks a benchmark for the digital transformation of the manufacturing industry. Its essence is to achieve autonomy and intelligence throughout the entire production process through technological integration. Shenyang Jingrui's intelligent production line has implemented this "dark factory" model, using RFID to manage tool life, achieving a 90% spindle utilization rate and reducing the overall cost of aviation parts by 30%.

IV. Future Trends: Cross-Border Integration and Intelligent Upgrades

Technology Penetration in the Medical and Aerospace Industries: 4-axis control technology in dental engraving machines has been extended to machining small precision aerospace parts; conversely, 5-axis experience in aerospace blade manufacturing is driving innovation in complex curved surfaces for orthopedic implants.

AI-Driven Intelligent Manufacturing: Delta's NC300's network functionality supports remote program transmission; Shenyang Jingrui's production line uses an "ant colony algorithm" for dynamic equipment scheduling, reducing production changeover time by 50%.

Green Manufacturing: Optimizing CNC processes during machining, such as tool life management and coolant recovery, supports the "dual carbon" goals.

Conclusion

The dominance of CNC technology in the medical and aerospace sectors stems from its ability to achieve extreme precision (micron-level), adaptability to complex geometries (multi-axis interpolation), and intelligent closed-loop control (online monitoring → real-time compensation). In the future, with the integration of AI, the Internet of Things, and new materials and processes, CNC technology will further reshape the boundaries of high-end manufacturing—from perfect dentures in the human body to fighter jet engines in the cloud, everything is defined by code and tools.
