Highlights from the Jin Tao Engraving Machine at the 2025 Macheng International Stone Expo

On October 26, 2025, the Central International Building Materials Exhibition Hall in Macheng was bustling with crowds as the three-day "Macheng International Stone Expo & Global Supply-Demand Matchmaking Event" kicked off. As a leading enterprise in China's stone machinery industry, Fujian Nan'an Jinta Machinery Co., Ltd. showcased a range of innovative products at the exhibition. Their booth was consistently surrounded by industry professionals, while the technical demonstration area drew gasps of admiration as attendees witnessed mesmerizing displays of "artistry on the cutting edge." This grand event not only provided Jinta Machinery with a platform to highlight its technological prowess but also marked a significant step forward in China's journey to establish itself as a global leader in high-end equipment manufacturing.

## Technological Breakthrough: 0.01mm Precision Engraving of "Along the River During the Qingming Festival"

In the core area of Jin Tao's exhibition booth, a smart engraving machine labeled "Doctor's Edition" is running nearly silently. Its cutting head glides smoothly across the surface of white marble, reproducing—with an astonishing precision of 0.01 millimeters—every intricate detail of Bianjing's bustling marketplace depicted in "Along the River During the Qingming Festival": the lively cries of merchants on the bridge, the ripples created by boats drifting along the river, even the delicate drooping lanterns beneath eaves. Remarkably, the technology behind this masterpiece vividly captures the subtle folds of figures' clothing down to the finest detail. On-site technicians explain that the machine is equipped with Jin Tao's independently developed "constant-power water-cooled frequency conversion motor" and a "full-servo motor gear reduction drive system," combined with advanced three-axis helical rack-and-pinion transmission technology, ensuring unparalleled stability even during prolonged, heavy-duty operations.

“Traditional carving machines require multiple tool changes to process 10-centimeter-thick granite, but our equipment can shape it in one seamless pass,” said Tao Zhengyong, Chairman of Jintao Machinery, pointing to another machine in the demonstration area. This “Hornet Model” engraving machine—specifically designed for granite—is currently slicing through a block of black granite at a blistering speed of 8,000 RPM. The cut surface is smooth as a mirror, with absolutely no chipping or cracking. According to the company, its standard配备 imported Yintai 30 linear square rails and highly wear-resistant helical racks boost the machine’s load-bearing capacity by 30%, while extending its lifespan to more than twice that of conventional models.

## Global Recognition: From Saudi Holy Mosque to Turkish Mosques

On the interactive screen set up on one side of the booth, global application cases of Jintaol carving machines were continuously displayed: During the expansion project of Mecca's Grand Mosque in Saudi Arabia, 30 units of Jintaol equipment worked non-stop for 72 hours straight, meticulously carving intricate patterns of verses from the Quran. In Afyon, Turkey—the "Marble Capital," artisans used the "Doctor Edition" model to faithfully replicate the ornate mosque carvings from the Ottoman Empire era, so realistically that even architectural historians found it hard to distinguish between the original and the replica. Meanwhile, at a mining site in South America, Jintaol’s cylindrical carving machine directly shaped Roman columns on raw stone blocks measuring 2 meters in diameter—eliminating the need for the traditional processes of cutting and assembling altogether…

“These projects have made us realize that Chinese manufacturing can completely shake off the label of ‘low-cost, low-end.’” Tao Zhengyong recalls collaborating with a Saudi royal family-owned factory in 2023. At the time, after inspecting equipment from countries like Italy and Germany, the Saudi team was ultimately impressed by Jinta’s “full-process service model”—which covers everything from equipment installation and commissioning to hands-on training for operators, and even includes ongoing remote maintenance support. Over three months, Jinta’s team guided the Saudi engineers from skepticism to full confidence. “They remarked that Jinta’s equipment isn’t just highly efficient—it also clearly demonstrates the systematic advantages of Chinese technology.”

Today, Jin Tao's global footprint spans 23 countries, with overseas sales accounting for 45% of its total revenue. At this year's expo, more than 10 buyers from the Middle East and Southeast Asia signed letters of intent on the spot, totaling over 20 million yuan in value.

## Innovation Ecosystem: From Tech Artisans to "Internet-Famous Bosses"

In stark contrast to the serious technical demonstrations, inside Jin Tao's exhibition booth—a "live-streaming zone"—Tao Zhengyong was calmly explaining the device’s specifications directly to the camera of his smartphone. "This flat engraving machine features an automatic lubrication system that can detect rail wear and replenish grease on its own..." Today, this post-90s entrepreneur boasts 580,000 followers on Douyin and is hailed by the industry as "the mechanical artisan who understands traffic best."

"In the toughest moments of the 2024 market, we secured 300 orders thanks to Douyin short videos," candidly shared Tao Zhengyong. He recalled how, at first, he felt nervous and even stumbled over his words while filming—but now, effortlessly showcasing the equipment's advantages on the spot, he and his team have developed a unique "technology + content" marketing strategy. Meanwhile, on the exhibition stand, an electronic screen continuously displayed real-time Douyin inquiry data: Over the past 24 hours, there were 127 new inquiries, with 43 of them coming from overseas users."

This innovative spirit has permeated every stage of Jin Tao's development. In 2021, Tao Zheng勇毅然决然 defied conventional opinions by investing in the R&D of a doctoral-grade carving machine, adopting a "no-expense-spared" approach that even saw the use of aerospace-grade materials for spindle manufacturing and the integration of an AI-powered visual correction system. By 2025, the company had secured two patents—namely, the "Articulated Stone Processing Machine" and the "Reinforced Support Stone Rotary Carving Machine"—enabling seamless, edge-to-edge machining of intricate curved surfaces without any dead zones.

## Blueprint for the Future: Decade to Cover the Global Market

At the forum held on the first day of the expo, Tao Zhengyong unveiled the "Jin Tao Decade Plan": to become the No. 1 player in China's stone carving machine market by 2026, establish five overseas production bases by 2028, and ensure that Jin Tao equipment is present in 80% of global stone processing plants by 2035.

“We don’t just sell equipment—we aim to deliver technology standards and a comprehensive service system.” He pointed to a remote operations and maintenance system displayed on the stand, explaining that, thanks to its IoT module, Jinta can monitor the operational status of equipment worldwide in real time, proactively alerting users to potential failures and even recommending tailored maintenance solutions. Currently, the system is already connected to 1,200 overseas devices, achieving an impressive customer satisfaction rate of 99.3%.

On the third day of the expo, the Jin Tao booth remained bustling with visitors. A buyer from Brazil, after trying out the equipment, gave a thumbs-up and remarked: "The speed and precision of China's carving machines have completely reshaped our perception of 'Made in China'." Meanwhile, Tao Zhengyong has already set his sights on even greater opportunities—on the planning map tucked away in the corner of the booth, he’s already marked plans to exhibit at the 2026 Hannover Industrial Fair in Germany and the 2027 Dubai Stone Fair.
