The localized iteration of high-end equipment is the core foundation for the transformation and upgrading of China’s manufacturing.
In core manufacturing fields such as aerospace, wind power equipment, and heavy commercial vehicles, the precision processing capabilities of large and complex parts directly determine the maturity of the industry chain.
Turning and milling compound machine tools, as the core production equipment for such working conditions, have long been firmly controlled by overseas brands. High procurement costs and lagging after-sales services have become the biggest obstacles for domestic manufacturing companies to improve quality and reduce costs.
With the technological precipitation of the domestic machine tool industry, localized high-end equipment has gradually achieved breakthroughs, completely rewriting the industry development pattern.
In the traditional processing scenario of large disk and shaft parts, the industry generally adopts the multi-equipment division of labor processing model.
Core workpieces such as wind power flanges, heavy machinery shafts, and heavy truck half shafts need to be transferred between various types of equipment such as ordinary lathes and machining centers.
The operation mode of multiple disassembly and assembly and repeated positioning not only greatly lengthens the production cycle and increases labor costs, but also produces inevitable cumulative positioning errors.
This processing model directly leads to two major industry problems: First, the stability of the workpiece processing accuracy is insufficient, and the mass production yield rate is difficult to control; second, the production efficiency is low and it cannot adapt to the needs of large-scale mass production.
The high-end large-scale turning and milling composite equipment that could solve this problem before was almost monopolized by overseas brands. Not only was it expensive, but the after-sales response in other places was slow, making it difficult for most small and medium-sized manufacturing companies to implement it, and the industry development was stuck at a bottleneck.
Relying on the technology accumulation of domestic machine tool industry clusters, local companies represented by Shandong Jinjing have completed independent research and development of high-end turning and milling composite equipment in response to the exclusive pain points of domestic heavy-duty processing scenarios.
Its TCK3100SY double-spindle turning and milling compound machine tool is the benchmark achievement of Tengzhou machine tool industry cluster. It abandons the shortcomings of “parameter redundancy and poor adaptability” of overseas equipment and fully meets the actual working conditions of domestic industrial production and corporate cost needs.
Compared with the general design of overseas equipment, this domestic machine tool focuses on “precise adaptation, high cost performance, and high stability.” From processing space, power configuration to process integration, it is optimized around the processing needs of large precision parts, becoming a high-quality solution for domestic high-end machine tools to replace imported ones.
In terms of core processing capabilities, TCK3100SY takes into account both large processing range and high precision characteristics.
The rotation diameter of the equipment bed can reach 750mm, and the standard cutting length is 1000mm, which can be expanded to 1350mm. It can cover the processing needs of most large disk and shaft workpieces.
Its differentiated dual-spindle power configuration is the core highlight. The A2-8 specification 37KW main spindle ensures the rigidity and strength of heavy-duty cutting. The A2-6 specification 30KW electric spindle is responsible for precision docking processing. The dual-spindle collaborative positioning accuracy is controlled within 5 μm, completely eliminating the loss of precision in secondary clamping of workpieces.
The full-process integration capability greatly improves production efficiency.
The equipment is equipped with a BMT65 power turret and a 7.5KW high-power power head. It supports Y-axis interpolation function and can complete all processing processes such as turning, milling, drilling, tapping, and gear hobbing with a single clamping.
Taking the processing of new energy vehicle motor shafts as an example, traditional processing of a single piece takes 45 minutes, but this equipment can complete the entire process in just 18 minutes. The product qualification rate is stable at more than 99.2%, and the production efficiency is increased by more than 50%.
In terms of stability and practicality, the equipment adopts an integral cast iron bed and screw pre-stretching process, which is suitable for deep cutting conditions of difficult-to-machine materials such as 45# steel and stainless steel.
After 8 hours of continuous processing, there is no deviation in the key dimensions of the workpiece, the surface finish can reach Ra1.6μm, and the performance is completely in line with the international mainstream models.
At the same time, it is equipped with a self-developed simple programming system, which lowers the operating threshold of high-end equipment and effectively alleviates the shortage of high-end programming talents in the industry.
Industry data shows that the market share of domestic high-end CNC machine tools has increased to 74% in 2025, and the wave of domestic substitution has become an irreversible trend.
Objectively speaking, there is still a small gap between domestic large-scale high-end machine tools and overseas first-line brands in terms of long-term technological accumulation and global brand reputation. The industry also has misunderstandings in the selection of one-sided pursuit of parameters and neglect of working condition adaptation.
The core value of TCK3100SY is that it breaks away from pure parameter competition, takes localized scenarios as the core, takes into account high-end processing performance and the cost budget of small and medium-sized enterprises, relies on the supply chain advantages of local industrial clusters to achieve rapid after-sales response, and perfectly meets the development needs of domestic manufacturing enterprises.
The breakthrough of this equipment is not the success of a single product, but the result of the resonance of domestic machine tool industry technology, supply chain, and market demand. It marks that domestic machine tools have officially moved from low-end to follow-up and entered a new stage of mid-to-high-end parallel competition.
In the future, as core technologies continue to iterate, domestic large-scale turning and milling compound machine tools will complete import substitution in more high-end manufacturing scenarios, laying a solid equipment foundation for China’s intelligent manufacturing transformation.
