On April 22, an event focusing on innovative development in the metal processing industry was held in Shanghai. Organized by Metalworking Magazine and guided by the Machinery Industry Information Institute, the event—titled the Fourth Machining Center User Survey Results Release and "Golden Edge Award" Machining Center Product Innovation Award Ceremony—concluded successfully.

This gantry machining center precisely meets the high-efficiency and high-precision machining requirements of large integrated die-castings for new energy vehicles. It has already been successfully adopted by several well-known domestic NEV manufacturers and die-casting plants, playing a key role in the post-processing of large structural components such as NEV front cabins, rear floors, and battery trays.

In terms of technological innovation, the machine features many highlights. It adopts a domestically developed single-beam, dual-five-axis head architecture. This unique design enables synchronized machining at two stations without interference, increasing machining efficiency by more than 35% compared to a single-head machine. For the drive system, linear motor drives (XY axes ≥70 m/min) are combined with dual servo ball screw drives (Z axis ≥50 m/min), achieving rapid three-axis traverse and significantly reducing machining time. The innovative follow-type left and right dual tool magazines move with the column, achieving a tool-to-tool change time of just 3 seconds, effectively improving machining continuity and efficiency. In terms of accuracy, the machine's positioning accuracy is ≤0.018 mm, repeatability ≤0.01 mm, and A/C axis accuracy reaches 8 arc-seconds, providing a solid foundation for high-precision machining.

Taking the machining of an NEV rear floor as an example, the dual heads work in coordination to achieve "multi-station work on one machine." Compared to conventional processes that use multiple machines for separate steps, the number of machines required can be reduced by 60%–70%. With one clamping and one process, 136 machining features on the front and back surfaces can be completed in just 643 seconds, significantly shortening production cycles, reducing equipment investment and floor space, and effectively helping customers achieve large-scale, intensive production.

In the field of NEV manufacturing, die-cast parts must undergo a series of systematic post-treatments, including surface treatment and precision correction, to meet the performance and appearance requirements of practical applications.

The LK Group has accumulated deep innovative technology and extensive industry experience in die-cast part machining. Fully considering product applications, material characteristics, and accuracy requirements, LK Group provides customers with comprehensive and excellent die-casting post-processing solutions, precisely meeting their development needs and continuously contributing significant strength to the growth of China's NEV industry.
