Win-Win Cooperation with Baoji CRRC Times Engineering Machinery Co., Ltd.

Recently, the supporting grinding wheels for the new type of metro grinding train, jointly developed by our company and Baoji CRRC Times Engineering Machinery Co., Ltd., successfully carried out on-site tests at a metro test section in a certain city. This marks an important phased achievement in the cooperation between the two parties and lays a solid foundation for the subsequent market-oriented application of this new type of metro grinding train.

As a key enterprise under CRRC in the field of railway and urban rail transit engineering machinery, Baoji CRRC Times Engineering Machinery Co., Ltd. inherits more than 60 years of industry accumulation and possesses profound technical strength and rich practical experience in the R&D and manufacturing of rail engineering equipment. Its newly developed new type of metro grinding train focuses on the current demand for efficient and precise metro track maintenance, aiming to solve industry pain points such as low operation efficiency and poor adaptability of traditional grinding equipment, and provide a new solution for improving the quality and efficiency of urban rail transit operation and maintenance.

Since receiving the cooperation invitation from Baoji CRRC Times Engineering Machinery Co., Ltd., our company has attached great importance to this project, set up a special technical R&D team, and deeply participated in the R&D of supporting grinding wheels for the new-type metro grinding train. During the R&D process, the technical teams of both parties have collaborated closely and interacted efficiently, giving full play to their respective advantages in the field: Baoji CRRC Times Engineering Machinery Co., Ltd. provided the overall technical parameters and operating condition requirements of the grinding train, while our company, relying on its core technical accumulation in the grinding wheel field, optimized the grinding wheel formula design, improved product process details, and focused on breaking through key technical difficulties such as grinding efficiency, service life and safety stability of the grinding wheel in response to the structural characteristics and operating scenarios of the new-type metro grinding train.

In the early stage of laboratory testing and workshop trial operation, the two parties jointly conducted multiple rounds of rigorous verification on the supporting grinding wheels. By accurately adjusting the abrasive ratio of the grinding wheel and optimizing the performance of the bonding agent, the developed grinding wheel successfully met the core requirements of the new-type metro grinding train for track disease repair and surface precision control. Both the grinding efficiency and operation quality have reached the expected standards, and it has successfully passed the workshop test review, meeting the on-site test conditions.

The on-site test carried out at a metro test section in a certain city this time simulated the complex working conditions of the actual operation line, focusing on verifying the comprehensive performance of the supporting grinding wheels in scenarios such as continuous operation and repair of different types of track damage. During the test, the supporting grinding wheel was perfectly matched with the new type of metro grinding train, showing excellent grinding stability, efficient disease removal ability and reliable safety performance. It can effectively repair common track diseases such as rail corrugation, spalling and chipping, significantly improve the efficiency and quality of track grinding operations, and provide strong guarantee for the safe and stable operation of subsequent metro lines.

The smooth progress of this on-site test is an important achievement of the deepened cooperation and collaborative innovation between the two parties, which fully demonstrates the cooperation concept of "complementary advantages, mutual benefit and win-win results". In the future, our company will continue to maintain in-depth cooperation with Baoji CRRC Times Engineering Machinery Co., Ltd., continuously track test data, optimize product performance, and help the new type of metro grinding train realize large-scale application as soon as possible. At the same time, our company will always focus on technological innovation in the field of rail transit operation and maintenance, deepen the R&D of core products, and contribute more professional strength to the high-quality development of China's urban rail transit.
