The production of milling machines in my country started late and was developed in the early 1980s. There are two main structural forms: one is to install a milling device on an agricultural wheeled tractor to form a simple cold milling machine with a simple structure. , Suitable for milling of asphalt pavements below medium strength; second, self-propelled cold milling machine, which has developed in the past two years, and the performance of the main models can fully meet the maintenance requirements of domestic high-grade highways and municipal roads , The good performance-to-price ratio also has a greater competitive advantage compared with foreign imported products, but there is still a big gap in terms of varieties, specifications, technical levels, and supporting parts.
The domestically-produced models draw more lessons from the technology and experience of European milling machines, and adopt international matching in the power, hydraulic and control systems. It can be said that the system configuration has reached the international advanced level. From the perspective of intellectual property rights, some domestic products such as CM2000 produced by Shaanxi Construction Machinery Co., Ltd. and CM1900 and CM1200 produced by Xi’an Hongda Transportation Technology Co., Ltd. not only have complete intellectual property rights, but also have complete machine systems, control systems and Its software design and manufacturing technology have reached the international advanced level.
