Looking back at the road cutting machines I used when I started my career, they were cumbersome, inefficient and had poor precision. Over the past two decades, I have led three technological revolutions that have completely transformed the industry. Each of these revolutions has raised the efficiency and quality of cutting operations to new levels.
The first revolution was the widespread adoption of "hydraulic servo control systems". Before 2008, most cutting machines still used mechanical linkage to control depth, with poor adjustment accuracy and strenuous operation. I was the first to introduce a closed-loop hydraulic servo system, which achieved digital precise adjustment of cutting depth through sensor feedback and proportional valves. I remember that during the construction of the Shanghai Expo Park road project, my first-generation servo control system increased the depth control accuracy from ±5 millimeters to ±1 millimeter. This breakthrough not only improved the quality of the project but also reduced the labor intensity of the operators by 70%. By 2012, servo control had become the industry standard configuration, and my system, due to its higher reliability and lower failure rate, occupied 40% of the global high-end market share.
The second revolution originated from "the breakthrough in diamond blade technology". In 2015, I collaborated with materials scientists to develop multi-layer composite diamond blades. Traditional blades have evenly distributed diamond particles, which fail when worn. My design arranged different particle sizes and hardnesses in layers, with the surface layer being fine particles for precision cutting, the middle layer being coarse particles for rapid cutting, and the bottom layer being ultra-hard particles for wear resistance. In extreme working conditions in the United Arab Emirates, this blade had a lifespan 2.8 times that of traditional products. More importantly, I optimized the matching algorithm between the blade and the equipment, using vibration sensors to monitor the cutting status in real time and automatically adjusting the rotational speed and feed rate. This intelligent blade management system reduced cutting costs by 35%.
The third revolution was the realization of "fully automated cutting systems". In 2020, I launched an automatic cutting machine based on GNSS and machine vision. Operators only need to input the coordinates of the cutting path and depth parameters, and the equipment can complete all operations automatically. In the smart road project in Shenzhen, my automatic cutting machine operated continuously for 72 hours at a complex intersection, cutting a total length of 5.2 kilometers, with a position error of less than 3 millimeters, without any manual intervention. My obstacle recognition system can automatically avoid road features such as manhole covers and markings. This system increased construction efficiency by 300% and reduced labor costs by 80%. Currently, I am developing a remote control system based on digital twins, and in the future, operators can control multiple devices simultaneously from an office and operate them at different construction sites around the world. Each technological revolution was not an isolated breakthrough but an overall advancement of the system engineering. I established a complete technological ecosystem: from basic material research to control system development, from production process optimization to on-site application verification. My R&D team maintains cooperation with 12 top universities worldwide to ensure the continuity and forward-looking nature of technological innovation. The true industry leader is not one who follows trends but one who creates trends - this is my consistent belief over the past 20 years.
