The AI liquid-cooling market is poised to reach hundreds of billions—what makes Dean Machine Tools capable of seizing this opportunity?

As AI computing power gains momentum, so does liquid cooling. According to data from CCID Consulting, China’s liquid-cooled data center market is projected to reach RMB 15.98 billion in 2025, up 45.2% year over year, with further growth to RMB 23.25 billion by 2026. Meanwhile, CICC forecasts that the global liquid‑cooling market for intelligent computing centers could surpass RMB 114.7 billion by 2026, representing a year‑on‑year increase of 273%. Additionally, data from the China Academy of Information and Communications Technology indicates that the penetration rate of liquid cooling in AI training servers has already reached 74%. Liquid cooling is transitioning from an optional feature to an essential requirement, and 2026 has been dubbed by the industry as the “year when liquid cooling volumes begin to surge.”

What truly presents opportunities for the machine tool industry is not “building servers” themselves, but rather the intricate, multi-layered liquid‑cooling components that underpin them—cold plates, vapor‑chamber heat spreaders, radiators, manifolds, and quick‑connect fittings. Among these, cold‑plate‑based liquid cooling dominates; as the power density of individual cabinets continues to climb toward 100 kW or higher, microchannel and vortex‑enhanced designs are becoming increasingly complex, driving ever‑higher demands on the precision and efficiency of CNC machining.

What exactly are the challenges in machining liquid-cooling components?

A seemingly simple liquid‑cooling plate actually demands extremely high machining precision: the flow‑channel width and depth tolerances must be maintained within ±0.02–0.05 mm, the sealing surface flatness must not exceed 0.05 mm, and the contact surface finish must reach Ra ≤ 0.8 μm. Moreover, components such as manifolds and quick‑connect fittings require intricate machining of angles, threads, and sealing surfaces. Production involves mixed‑material lines—aluminum alloy, copper, and others—and large‑size plates are prone to warping and deformation.

Low‑roughness, burr‑free flow channels with consistent tolerances are essential for cold plates to pass airtightness and pressure‑resistance tests—any leakage could bring down the entire cabinet. In fact, when it comes to machining liquid‑cooling components, the key is no longer simply “being able to do it,” but rather “doing it well, doing it reliably, and doing it quickly.”

How should customers choose a machine tool? First, consider the workpiece; then, evaluate three key performance indicators.

The selection criteria are straightforward: first, categorize the workpiece type. For flat‑type components such as cold plates, heat sinks, and base plates for vapor chambers, prioritize high‑rigidity vertical machining centers. For rotary parts like manifolds, fittings, and tubing, opt for turning or turn‑mill machining. For complex, multi‑angle manifolds and integrated assemblies, choose five‑axis machining or hybrid machining processes.

Now let’s examine three key performance indicators: first, rigidity, which determines the stability of heavy‑cutting operations and long‑term precision; second, thermal stability, which ensures consistent batch‑to‑batch machining; and third, spindle speed and accuracy, which dictate the quality of microchannel flow paths. Finally, consider your production capacity planning: once in volume production, will you need to integrate automation such as gantry systems or robotic loading/unloading?

Dean Machine Tools: Which models are suitable for this industry?

For planar and channel‑type components such as cold plates, heat sinks, and vapor chambers, the DNM series vertical machining centers are recommended. With global sales exceeding 30,000 units, the DNM series comes standard with a direct‑drive spindle and roller‑type linear guides, along with a high‑rigidity machine bed. Optional features include high‑speed spindles and thermal‑deformation compensation, making it particularly well suited for precision finishing of flow channels and sealing surfaces in aluminum alloy and copper cold plates.

For rotary components such as manifolds, quick‑connect fittings, and pipe fittings, we recommend the Lynx and PUMA series turning centers. For complex, multi‑angle manifolds and integrated assemblies, consider the SMX turn‑mill center or the DNM 5AX five‑axis machining center, which can perform multiple operations—turning, milling, drilling, and tapping—in a single setup, thereby minimizing errors associated with secondary setups.

The Advantages of Dean Machine Tools

High Rigidity: Featuring a resin-bonded sand‑cast bed and a symmetrical layout, the high‑strength gray cast iron delivers overall rigidity that exceeds conventional designs by more than 30%, ensuring greater stability during heavy cutting operations.

High Precision: The direct-drive spindle minimizes vibration and noise, and when combined with thermal deformation compensation, it ensures consistent precision even during extended, high-volume machining.

High Efficiency: By optimizing chip-to-chip tool-change times and the acceleration/deceleration performance of the spindle system, output is significantly increased in high-volume production applications such as liquid-cooled components.

Service Assurance: Dean Machine Tools operates four subsidiaries, 35 distributors, 47 technical centers, and 223 service outlets across China. As the leading distributor for Dean Machine Tools in China, Shinming Technology provides localized services spanning process validation, equipment selection, and full‑lifecycle after-sales support.

When faced with a dividend, first think clearly about these three things.

For companies looking to enter the AI‑driven liquid‑cooling machining market, assessing whether a machine tool is worth investing in requires more than just chasing hype. First, clarify three key questions: Is the target workpiece a flat cold plate or a rotary manifold? How stringent are the requirements for precision and rigidity? And will automation be necessary after mass production? Once these factors are clearly defined, engage a specialized team to conduct process validation—only then can you reliably capitalize on this wave of opportunities.

Liquid‑cooling machining represents a dual upgrade—both in process and equipment—and choosing the right machine tool is even more critical than rushing to seize market opportunities.
