On September 4, the China Securities Regulatory Commission issued an official approval for the initial public offering registration of Guangdong Kerui Si CNC Technology Co., Ltd., according to information from Zhitong Finance.

The company plans to list on the Shanghai Stock Exchange's STAR Market, with Guotai Haitong Securities serving as its sponsor. The proposed fundraising target is set at 719 million yuan.

According to the prospectus, Kerui Si specializes in the research, development, production, and sales of full direct-drive CNC machine tools and CNC system products. It stands as a domestic leader in this niche and is one of the few companies in China that simultaneously offers both PWM-type and bus-type CNC systems, with both product lines having achieved significant sales volumes.

To date, the company's CNC system products have surpassed 20,000 units in cumulative sales and usage. These systems are applied across precision milling machines, precision grinders, five-axis linkage machine tools, three-dimensional five-axis lasers, force-controlled polishing equipment, and automation-related devices. They have successfully replaced mainstream systems from global giants such as Siemens (Germany), Heidenhain (Germany), Fanuc (Japan), and Mitsubishi (Japan), earning notable market recognition.

Among its achievements, the company's U-series PWM-type CNC system has broken the monopoly that Heidenhain once held over the Chinese machine tool market for this technology. In the domestic market, Heidenhain and Kerui Si now serve as the primary suppliers of PWM-type systems. Separately, the N-series bus-type CNC system, praised for its performance and stability, has been successfully sold to several globally renowned automation solution providers, including Fanuc Robotics.
