Information activities
Recently, a major technological innovation achievement by Ezhou Kebei Laser Co., Ltd. made the front page of the *Ezhou Daily*. This “Little Giant” enterprise—specializing in niche, high-tech, and innovative fields—is located in the national-level Gedian Economic and Technological Development Zone. The company has officially delivered the nation’s first automated blanking production line for fish-belly H-beams, developed in collaboration with Hunan CRRC. This milestone marks a major technological breakthrough for H-beam laser cutting machines in Hubei’s intelligent equipment sector and injects robust “Hubei-style” momentum into the industrial upgrading of high-end equipment manufacturing.

Challenges in Traditional Large-Scale Machining
V-shaped girders serve as the core load-bearing components in rail transit vehicles and railway flatcars. Traditional machining methods have long been plagued by issues such as low efficiency, poor precision, high costs, and heavy reliance on manual labor, severely hindering the industry’s large-scale development.
Focusing on these critical industry bottlenecks, Kebei Laser partnered with leading industry players to tackle the challenge head-on. In just 50 days, they successfully developed an intelligent laser cutting production line for H-beam fishbelly girders, overcoming the challenges of manufacturing heavy-duty rail transit components with remarkable speed—the “Kebei Speed.”

New Breakthrough in Domestic Technology
Soaring Productivity: The production line innovatively adopts synchronous cutting technology using a dual-head gantry-type H-beam laser cutting machine, more than doubling processing efficiency compared to traditional single-head equipment. It can complete the fully automated processing of 12-meter-long profiles in a single pass. The entire process—from loading, positioning, and cutting to unloading—is fully automated, achieving a daily output of over 80 units and fully meeting the demands of large-scale production.
Leading Precision: Beyond high efficiency, precision is another core strength of this production line.
“The production line integrates 3D six-axis cutting and beveling functions, enabling flexible adaptation to the high-precision machining requirements of complex joints in rail vehicles. ” Fan Wenfeng, Sales Director at Ezhou Kebei Laser Co., Ltd., explained that the Kebei H-beam laser cutting production line can be directly connected to 3D design software to enable automatic nesting, significantly reducing programming and manual intervention. With positioning accuracy as high as ±0.1 mm/m, the processed cross-sections are smooth and flat, eliminating the need for secondary grinding and ensuring high-quality output.
Looking Ahead
“We remain committed to our mission of ‘smart manufacturing and revitalizing the nation through technology,’ and are fully dedicated to mastering key core technologies,” said Fan Wenfeng. He added that the company is accelerating the development of a modern industrial platform that integrates R&D, production, and sales, with an expected annual production capacity of 500 H-beam laser cutting machines and an annual output value exceeding 400 million yuan.
From the “Kebei Speed” achieved through a 50-day intensive effort to the “Kebei Precision” of the dual-laser-head system, the successful delivery of this nation’s first fish-belly girder production line once again demonstrates Kobe Laser’s formidable capabilities in the field of intelligent equipment. Moving forward, Kebei Laser will continue to be driven by technological innovation, contributing even more “Kebei Strength” to China’s high-end equipment manufacturing industry.
