From AI to Computing Power, and Computing Power to Precision Manufacturing: Haozhi's Integrated Solutions for Core Functional Components

The ultimate limit of Artificial Intelligence is computing power, and the ultimate limit of computing power is precision manufacturing. Whether dealing with advanced process chips, high multi-layer PCBs, or liquid cooling systems, performance ceilings and mass production yields ultimately depend on the process limits of foundational precision manufacturing. Without high-end precision manufacturing, scalable AI computing power cannot exist.

During the construction of AI computing infrastructure, three core scenarios—high-end PCB micro-hole drilling, ultra-thin wafer grinding, and mass production of complex liquid cooling components—widely face industry pain points such as low production yields, insufficient precision stability, and high process adaptation difficulty.

With decades of deep cultivation in high-end machine tool functional components, Haozhi possesses world-class technical capabilities in AI-related precision manufacturing, providing high-precision, high-stability integrated solutions for PCB, semiconductor, and liquid cooling tracks with mature mass-production delivery capabilities. Notably, Haozhi's PCB drilling spindles command over 60% domestic market share, while router spindles exceed 80%, extensively validated by the market and highly trusted by global customers.

1. Advanced PCB Precision Manufacturing: Ensuring Stable Mass Production for High-End Processes

The upgrade of AI server computing power continues to elevate PCB technical specifications: mainboard layers have increased to 30–40 layers, materials have upgraded to M8 and M9 grades, and aspect ratios have risen from conventional server standards of 15:1 up to 20:1–26:1. The rotational speed, torque, dynamic precision, and thermal stability of drilling and routing processes directly dictate batch production efficiency and yield rates.

Haozhi has built an extensive 160,000 to 400,000 RPM PCB electric spindle system, precisely matching various hole diameters, board thicknesses, and machining processes:

• 160,000 RPM Spindle: Delivers a high torque of 0.26 N·m at 20,000 RPM (a 37% increase over peer products), efficiently meeting high-precision machining demands for M9-grade copper-clad laminates in the AI sector.

• 320,000 RPM Spindle: Ideal for high-precision drilling with hole diameters ranging from Φ0.05mm to Φ5mm.

• 400,000 RPM Ultra-High-Speed Spindle: Features static runout accuracy ≤ 2μm and dynamic precision ≤ 6μm, offering unparalleled high precision and high efficiency.

In the routing process, Haozhi's PCB router electric spindle adopts an innovative "one-stroke routing" process, replacing traditional rough and finish milling two-stage machining.

Under testing conditions of tool D=2mm, S=30,000 RPM, F=0.5m/min, R=16.0m/min, routing speed 1.0m/min, and board thickness 4×1.6mm FR4, processing efficiency is increased by 38.9%, with panel and bottom plate dimensional deviations kept ≤ 0.05mm. With a 50% torque increase and an intelligent temperature control system, it stably processes HDI boards, automotive boards, high-Tg rigid boards, and thick copper boards.

With exceptional mass-production stability, Haozhi's PCB drilling spindles hold over 60% domestic market share and routing spindles exceed 80%, securing a top-tier position in the global electric spindle industry as a core driving force for high-end PCB precision manufacturing.

2. Wafer Ultra-Precision Machining: Nanometer-Level Accuracy Control

Wafer thinning, dicing, and inspection are core precision processes in chip manufacturing. With the widespread adoption of 12-inch large-size, ultra-thin wafers and wide-bandgap semiconductor hard-and-brittle materials, vibration damping performance, structural rigidity, rotational accuracy, and long-term stability have become critical thresholds where minor precision fluctuations can reduce wafer yields.

Targeting the rigorous working conditions of semiconductor ultra-precision manufacturing, Haozhi offers comprehensive product solutions covering wafer grinding, dicing, and inspection processes:

• Wafer Grinding Spindle: Achieves full-speed vibration ≤ 0.1mm/s, axial stiffness of 800N/μm, radial stiffness of 200N/μm, and rotational motion error as low as 20 nanometers. This ensures 12-inch workpieces achieve a surface Total Thickness Variation (TTV) < 3μm and surface roughness Ra < 0.02μm.

• Dicing Machine Spindle: Features an innovative structural design that enhances rigidity and load capacity by 14.3% compared to market peers; high-precision interface design achieves taper runout ≤ 0.5μm, while tool holder mounting surface radial and axial runouts are both ≤ 1μm. Continuous machining elongation fluctuation is ≤ 0.3μm with rotational motion error reduced to 80 nanometers, reaching international advanced performance levels.

• Wafer Inspection Air Static Turntable: Utilizes a unique slotted cavity structure and narrow-gap sealing design in its air-floating sleeve, achieving non-contact high-speed vacuum adsorption and eliminating accuracy impacts from contact-type rotary joints. Supporting speeds up to 4,800 RPM, it maintains positioning accuracy ≤ ±20μrad (≤ ±4.12''), repeatability ≤ ±10μrad (≤ ±2.06''), and rotational runout ≤ 200nm for ultra-precision wafer inspection.

From grinding to inspection, Haozhi provides a solid foundation for independent and controllable semiconductor industrial chains through nanometer-level precision control.

3. AI Computing Power Liquid Cooling Components: Machining Complex Structural Parts

As AI computing cluster power consumption continues to surge, liquid cooling has become the mainstream thermal management solution for intelligent computing centers and high-end servers. Core components such as liquid cooling plates, CDU modules, and valve bodies feature difficult-to-cut materials, complex flow channels, thin-walled susceptibility to deformation, and strict sealing tolerances, imposing compound high-precision demands on machine tools.

Leveraging its diverse product portfolio including spindles, turntables, linear motors, and guide rails, Haozhi covers the entire workflow of rough and finish machining for liquid cooling components:

• Drilling & Tapping Electric Spindle: Accelerates to 24,000 RPM in 0.6 seconds and 30,000 RPM in 1.1 seconds—roughly twice the response speed of traditional direct-coupled spindles, minimizing idle waiting times during frequent starts and stops. Under oil-air lubrication, working speeds reach 40,000 RPM, offering remarkable efficiency in high-speed, light-load milling of aluminum cold plates. Dual-winding motors and oil-air lubricated bearings can be flexibly configured, offering rated torques of 12N·m (low-speed winding) and 7.4N·m (high-speed winding) to handle copper cold plates, aluminum distribution blocks, and stainless-steel fittings.

• Ultra-High-Precision Direct-Drive Turntable: Equipped with ultra-high-precision absolute encoders, delivering maximum positioning accuracy of ±3'' and repeatability of ±1''. Optional super motors increase rated torque by 50% at identical volumes while reducing self-weight by 5%, delivering stronger power output in compact spaces.

• High-Performance Linear Motor: Supports high speeds up to 90m/min and 2G acceleration, with bidirectional repeatability up to 1μm. Continuous thrust ranges from Fcn = 102N to 10,636N, peak thrust from Fpk = 276N to 26,428N, and thrust ripple < 3% for smoother trajectory tracking.

• High-Precision Guide Rail: Features minimal static-dynamic friction difference for nanometer-level feed positioning. Excellent mechanical structural design effectively reduces friction loss, maintaining long-term running accuracy.
