Dongguan Qizhong Hardware Machinery Co., Ltd.

These R&D efforts aim to enhance the performance, efficiency, and reliability of industrial cutting tools while reducing costs and environmental impact.

1. Material Innovation: Developing more wear-resistant and high-temperature-resistant materials, such as cemented carbide, ceramics, and ultra-hard materials (e.g., diamond and cubic boron nitride), to enhance tool lifespan and cutting performance.

2. Coating Technology: Applying advanced coatings (e.g., TiN, TiAlN, AlCrN) using Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD) to improve hardness, heat resistance, and wear resistance.

3. Geometric Design Optimization: Utilizing Computer-Aided Design (CAD) and Finite Element Analysis (FEA) to optimize tool geometry (e.g., edge angles, rake angles, clearance angles) for improved cutting efficiency, reduced cutting forces, and extended tool life.

4. Smart Manufacturing & Automation: Integrating Industry 4.0 technologies to develop intelligent tool systems capable of real-time monitoring (e.g., wear, temperature) and optimizing machining processes through data analysis and feedback.

5. Sustainability & Eco-Friendliness: Researching eco-friendly tool materials and manufacturing processes to minimize environmental impact and improve resource efficiency.

6. Application Expansion: Designing specialized tools for high-precision and high-strength machining in industries like aerospace, automotive, and medical manufacturing.
