Abstract The AA band saw blade from Hunan Taijia New Material Technology Co., Ltd. has experienced significant transformation in recent years. Whether it's cutting medium and low carbon steel, non-ferrous metals, or even stainless steel, the company has built a solid reputation in the market. This success is largely due to continuous innovation in band saw blade technology.
The development of the AA band saw blade wouldn't have been possible without the support of dedicated professionals. Among them, Mr. Hayden, a renowned sawing technology consultant, has played a vital role. With over 7 years of collaboration with the company, he has contributed immensely to the technological advancement of the product.
Mr. Hayden, now 77, is a respected expert in the field of band saw blades. His deep knowledge and experience have earned him admiration from colleagues at all levels within the company. In 2007, the domestic bi-metal band saw blade industry was still at the level of European and American standards from the 1960s, with high-end markets dominated by imported brands. At that time, the AA brand was considered one of the best domestically, but its application was limited to softer materials like medium carbon steel and non-ferrous metals. When it came to harder materials such as die steel, most customers preferred imported options.
Back then, the production equipment and technology in the company’s band saw blade workshop were outdated. To overcome this challenge, the company brought in several senior consultants from European and American companies, with Mr. Hayden being the longest-serving technical advisor. Thanks to his guidance, the manufacturing process of the AA band saw blade improved dramatically within just seven years, driving the entire industry forward.

Mr. Hayden is studying how to improve the quality of the milling teeth of band saw blades.
With a career spanning 30 years at Sandvik, Mr. Hayden is not only an expert in band saw blade research and production but also a prolific inventor. A significant portion of patents related to band saw blades in Europe and America are either authored by him or inspired by his work. He has pioneered several key innovations in the global band saw blade industry.
His serious and meticulous approach to work is something every Chinese manufacturer should learn from. Once, he noticed that the split-tooth models did not meet specifications, which affected geometric accuracy. While the on-site staff didn’t seem concerned, Mr. Hayden was visibly upset. For days, he kept pushing for improvements. Eventually, he confronted the team, saying, “SR, do you know what I did today? Your gear machine can’t open now.†After a moment of surprise, he added, “I’ve hidden some garbage so you can’t find it anymore!†Though he later apologized, the message was clear: “You guys, if you keep doing things improperly, I’ll take your things!â€
This incident left a deep impression on me. As a member of the company, I realized how much more urgency we needed in improving product quality compared to someone from abroad.
On another occasion, he spent an entire day at the milling site, working alongside the team and sharing stories about his long career. Despite the physical and mental exhaustion, I was amazed by his energy and dedication. It takes incredible patience and perseverance to maintain such a high standard of work at his age.
He never hesitates to dive into complex technical problems, exploring various solutions and proposing new methods. Since 2007, he has continuously suggested improvements to the quenching and tempering process, gradually refining the company’s technology. He also regularly trains core engineers and executives, spreading his advanced knowledge and quality concepts. Under his influence, many employees have adopted a rigorous and professional work ethic.
Working with Mr. Hayden is not just a professional relationship—it’s an enjoyable experience. He brings humor and passion to his work, making the process feel like "playing" rather than "making." The company’s executives and technicians have become close friends with him, and he always seems happy. To him, every band saw blade is like his own grandchild.
As the old saying goes, “Those who know are not as good as those who love, and those who love are not as good as those who enjoy.†Mr. Hayden has spent decades perfecting his craft with a true passion for the art of band saw blade manufacturing. His spirit has inspired countless people within the company, and under his guidance, the manufacturing level of the company has significantly improved.
In just a few short years, the company completely transformed from a traditional, low-quality workshop to a modern enterprise with advanced manufacturing technology comparable to international standards. This progress has helped elevate the reputation of domestic brands like AA, once looked down upon by foreign competitors.
In 2010, to recognize his outstanding contributions to China’s band saw blade technology, Hunan Province awarded Mr. Hayden the "Hunan Province Xiaoxiang Friendship Award."
Thanks to his guidance, the AA band saw blade has successfully entered the traditionally dominated European and American markets, gaining recognition for its performance and reliability. Today, AA products are considered top-tier in their category, proving that innovation and dedication can truly change the game.E27 Outdoor Wall Light,Outdoor Lamp E27,E27 Outdoor Light,E27 Outdoor Lamp
