Hengxing's Middle-Drive Double-Head CNC Lathe 200% Efficiency Boost, Global Reach

Nestled in Qufu, the cultural heartland of Shandong Province, Shandong Hengxing Heavy Industry Technology Co., Ltd. has emerged as a trailblazer in the global precision shaft parts processing sector, all thanks to its independently developed middle-drive spindle double-head CNC lathe. This cutting-edge equipment has not only redefined efficiency standards in the industry but also solidified the company’s reputation for unwavering processing quality, earning it widespread acclaim in both domestic and international markets. As of now, Hengxing Heavy Industry boasts long-term cooperative partnerships with over 800 clients spanning across continents—from automotive manufacturers in Europe to construction machinery producers in Southeast Asia—supporting an annual turnover that consistently hovers around 120 million yuan. This stable financial performance and global customer base stand as a testament to the company’s ability to deliver reliable, high-performance solutions that meet diverse industrial needs.

Step inside Hengxing Heavy Industry’s intelligent production workshop, and the hum of advanced machinery paints a vivid picture of modern manufacturing excellence. Rows of double-head CNC lathes operate at high speed, their movements synchronized with precision. The workshop’s automated feeding system takes center stage here: it accurately transports raw blank parts to designated processing positions, eliminating the delays and errors associated with manual handling. Once the middle-drive spindle is activated, the cutting tools at both ends of the lathe spring into action simultaneously, seamlessly completing the processing of both ends of a long shaft part in less than ten minutes—a feat that was once unthinkable with traditional equipment. “In the past, using single-head machines meant we had to finish one end of the workpiece first, then manually reverse it to process the other end,” explains Liu Lei, a senior mechanical engineer at the company’s R&D center. “This not only dragged out production time by 30% or more but also made it nearly impossible to ensure concentricity—a critical requirement for high-precision shaft parts. Clamping errors and inefficient process flows have plagued the industry for decades, limiting both precision and productivity.”

To overcome this long-standing challenge, Hengxing Heavy Industry assembled a dedicated R&D team, focusing its efforts squarely on perfecting the middle-drive spindle technology for double-head lathes. The road to innovation, however, was far from smooth. During the initial design phase, the team grappled with persistent issues of synchronous precision deviation— a problem that repeatedly brought development to a halt. Undeterred, team members essentially “moved into” the laboratory, working round-the-clock to test new solutions. They adjusted the transmission structure dozens of times, fine-tuned control programs with microscopic precision, and even collaborated with academic experts to analyze mechanical dynamics. After months of relentless effort, they finally broke through the technical bottleneck of double-end synchronous drive. The result? A self-developed middle-drive spindle that enables the lathe to process both ends of a workpiece simultaneously, completely eliminating the concentricity issues of traditional methods. When paired with the automated feeding system, the equipment also reduces manual intervention by over 60%, minimizing human error and further boosting efficiency.

Hengxing Heavy Industry’s commitment to innovation did not end with this breakthrough. The company continued to push for technological iteration, upgrading its double-head CNC lathes from the first to the second generation with a key modification: replacing the pneumatic spindle with a hydraulic one. This seemingly simple change led to a qualitative leap in performance—processing precision improved by 25%, and clamping stability was enhanced significantly, allowing the equipment to handle more complex and demanding tasks. Today, the lathe can process workpieces with an impressively wide size range: diameters from 15mm to 350mm and lengths from 100mm to 6000mm. This versatility makes it ideal for meeting the customized needs of diverse industries, including automotive (for engine shafts), construction machinery (for hydraulic cylinders), and even aerospace (for small precision components). These technical advantages have translated into tangible results: the company now produces approximately 300 double-head CNC lathes annually, holds over 40 utility model patents, and ranks among the top in China in terms of both product quality and market share.

The market response to Hengxing Heavy Industry’s double-head CNC lathes has been overwhelmingly positive. In the first half of this year alone, sales exceeded 160 units—with 40% of these going to international markets—and the product qualification rate remained steadily above 99%, a figure that far surpasses industry averages. Looking ahead, the company has no plans to slow down. It will continue to invest in R&D, focusing on meeting the growing demand for longer-size workpieces and higher precision processing. By doing so, Hengxing Heavy Industry aims to further consolidate its technical advantages in the double-head CNC processing field and provide more efficient, reliable equipment support for the global manufacturing industry’s transformation and upgrading—solidifying its position as a leader in the era of smart manufacturing.
