   Representative Equipment:

   • Mazak Variaxis / Integrex 5-axis machining centers: Complete complex machining of semiconductor vacuum chambers and wafer manipulators in a single clamping.
   • Citizen / Tsugami Swiss-type lathes: Achieve 0.001 mm turning-milling compound precision, suitable for medical orthopedic implants and miniature 3C components.
   • Makino high-rigidity machining centers: Applied to mirror finishing of optical lenses and aviation thin-walled parts.
2. Breakthroughs in Difficult-to-Machine Materials

   Focused on processing quartz, graphite, titanium alloys, superalloys, cemented carbide and other materials for semiconductors, medical treatment and aerospace.

   Key Technologies:

   • High-rigidity spindles with special tools and dust / chip removal systems (for graphite / quartz).
   • Low-speed high-torque cutting, minimal quantity lubrication (MQL) and anti-vibration systems (for titanium alloys / superalloys).
   • Mazak Friction Stir Welding (FSW): Defect-free joining of aluminum alloy and copper components.
3. Integration and Flexible Automation
   • Multi-process Integration: Turning-milling-grinding, drilling-tapping-boring, and additive-subtractive hybrid manufacturing to reduce clamping times and improve consistency.
   • Automated Cells: Machine tools + robots + AGVs + on-line measurement to realize 24-hour unmanned production of batch precision parts.
4. AI Intelligence and Digital Closed-Loop Control
   • AI CNC Systems (Huazhong Type 10, Siemens 840 sl advanced): Adaptive cutting, vibration suppression, tool life prediction and process optimization.
   • Precision Measurement Zone (Zeiss, Hexagon, Keyence, Mitutoyo): Coordinate measuring machines, laser scanning and on-line inspection to form a closed loop of machining – measurement – compensation.
5. Precision Parts Solutions for Key Industries
   • Semiconductors: Quartz crucibles, graphite heaters, vacuum chambers, wafer components, liquid-cooled cold plates.
   • Medical Devices: Orthopedic implants, minimally invasive instruments, precision parts made of titanium alloy and medical stainless steel.
   • New Energy Vehicles: Lightweight structural parts, motor housings, electronic control boxes, post-processing of integrated die-castings.
   • 3C / Aerospace: Micro structural parts, complex cavities, thin-walled parts with high surface quality.

1. Precision Upgrade:
   Shifting comprehensively from micrometer-level to nanometer-level to meet higher requirements in semiconductors, medical treatment and optics.
2. Material Adaptability:
   Mature specialized solutions for difficult-to-machine materials, with significant improvement in domestic equipment capabilities.
3. Intelligent Autonomy:
   Deep empowerment of AI, popularization of self-diagnosis, self-optimization and unmanned operation of machine tools.
4. Integrated Efficiency:
   Full-process machining in one clamping and integrated automation to shorten cycles and reduce costs.
5. Accelerated Domestic Substitution:
   Domestic 5-axis machines, control systems and cutting tools have gradually made breakthroughs in medium-to-high-end precision machining.

The exhibition shows that precision parts processing is moving toward ultra-precision, intelligence, integration and automation.

• For enterprises: Prioritize the layout of 5-axis integration + automation + on-line measurement, focusing on high-value tracks such as semiconductors, medical treatment and new energy.
• For technology: Precision, materials, intelligence and flexibility represent core competitiveness.
• For industry: Precision manufacturing in the Yangtze River Delta is accelerating upgrading, and the gap between domestic equipment and international advanced levels continues to narrow.
