I. Industry Insights: The Boom of Humanoid Robots and the Critical Role of Machine Tool Upgrades
In 2026, companies including Tesla, Figure, Unitree, AgiBot, and UBTECH have begun moving toward mass production of humanoid robots, signaling that the industry is transitioning from technology validation to large-scale commercial deployment. According to Goldman Sachs, the global humanoid robot market is expected to exceed USD 150 billion by 2035.
However, the mass production of humanoid robots faces dual supply bottlenecks. On the one hand, as a core transmission solution for linear joints, inverted planetary roller screws rely on high-end thread grinding machines for high-precision manufacturing, while the core components of these grinding machines have long been dominated by overseas brands. On the other hand, key robotic components such as harmonic reducers and joint modules are also highly dependent on imports. High prices, long delivery lead times, and delayed technical services have become major constraints on the industry's development.
Leveraging its extensive expertise in both machine tools and robotics, Haozhi Industrial has developed a comprehensive product portfolio covering “core components for screw processing equipment + core functional components for robots,” providing customers with one-stop solutions.
II. Platform-Based Solutions: Covering Both Machine Tools and Robotics
Relying on R&D platforms including a National Enterprise Technology Center, a Provincial Engineering Research Center for Motorized Spindles, and a Postdoctoral Research Station, Haozhi Industrial has established a comprehensive product system covering both machine tools and robotics:
Machine Tool Sector: Products cover motorized spindles, rotary tables,milling head, linear motors, ball screws and linear guides, servo motors, servo drives, and more, serving more than 90% of domestic machine tool manufacturers. Haozhi Industrial's motorized spindle has received the “Manufacturing Single-Product Champion” recognition from the Ministry of Industry and Information Technology of China, as well as the First Prize of the Guangdong Provincial Science and Technology Progress Award.
Robotics Sector: Products cover harmonic reducers, frameless torque motors, joint modules, and other core components, with long-term and stable partnerships with leading companies in the robotics industry.
Unlike traditional suppliers that provide only individual components and leave customers to integrate them independently, Haozhi Industrial has developed a vertically integrated solution platform spanning from “manufacturing equipment” to “core components.” On the machine tool side, Haozhi Industrial provides core components for high-precision thread grinding machines used in screw processing equipment. On the robotics side, it provides integrated solutions for robot manufacturers.
01 Machine Tool Sector: Core Component Solutions for High-Precision Thread Grinding Machines
For external thread grinding applications involving screws and planetary roller screws, Haozhi Industrial adopts a dual-core configuration of a “grinding wheel spindle + workpiece spindle,” complemented by a feed system to form a complete, coordinated solution.
1. Hydrostatic/Hydrodynamic Thread Grinding Spindle: Delivering Precision Power for High-Precision Screw Processing
DYFDM-160(080)50/9.4 Hydrostatic/Hydrodynamic Thread Grinding Spindle
Featuring a proprietary hydrostatic bearing support structure, the spindle uses a high-pressure oil film to replace the solid-to-solid contact of conventional rolling elements, delivering enhanced precision, rigidity, vibration damping, and service life. It serves as a core component for high-precision thread grinding.
Ultra-High Precision with Long-Term Stability: Leveraging the error-averaging effect of the oil film, radial runout at the spindle nose is ≤0.5 μm. Since there is no direct metal-to-metal contact between the spindle and bearing, spindle accuracy can be maintained over the long term, outperforming the initial accuracy of ≤1 μm and accuracy degradation characteristics of conventional ball-bearing spindles.
High Rigidity and Resistance to Off-Center Loads: The incompressibility of the high-pressure oil film provides rigid spindle support. During grinding of screw/planetary roller screw external threads and raceways, the grinding wheel is subjected to continuous radial cutting forces, placing extremely high demands on spindle rigidity. Haozhi Industrial's 160-series hydrostatic/hydrodynamic spindle achieves radial stiffness of ≥200 N/μm and axial stiffness of ≥350 N/μm. Its high-rigidity support effectively withstands off-center loading moments during grinding, constraining radial and axial displacement of the grinding wheel and ensuring high-precision machining.
Excellent Vibration Damping for Superior Surface Quality:Full-speed-range vibration is<0.3 mm="">
Long Service Life with Low Maintenance: The absence of direct metal-to-metal contact between the spindle and bearing enables near-zero-wear operation. Periodic bearing replacement is unnecessary, significantly improving equipment utilization while reducing after-sales and maintenance costs. In conventional ball-bearing spindles, rolling elements are subjected to prolonged contact stress, making them susceptible to fatigue spalling and requiring periodic downtime for replacement.
2. High-Torque, High-Rigidity Workpiece Spindle: Ensuring High-Precision Machining
DGZYM-2000.4/6.5-FWVM Workhead Spindle
As the rotational reference axis for thread forming, the workpiece spindle forms a high-precision pair with the grinding wheel spindle and directly determines the indexing accuracy and concentricity of the screw:
Stable High-Torque Output: Featuring a high torque-density motor design, the spindle delivers a maximum torque of up to 248 Nm, ensuring dynamic response and overload capability under low-speed, high-torque operating conditions.
High Load Capacity and Deformation Resistance:The front-end cantilever structure of the shaft system has been optimized, achieving axial load-bearing stiffness of >700 N/μm and radial load-bearing stiffness of >1,000 N/μm. This effectively suppresses vibration and deformation during machining, ensuring machining accuracy and surface quality.
3. Precision Feed System: Fully Closed-Loop Domestic Solution
High-Performance Linear Motor: Supports a maximum speed of 90 m/min and acceleration of up to 2G, with bidirectional repeat positioning accuracy of up to 1 μm. Continuous thrust Fcn = 102 N–10,636 N, peak thrust Fpk = 276 N–26,428 N. Thrust fluctuation is<3%, enabling="" smoother="" trajectory="" motion.="">
High-Precision Guideways: The small difference between static and dynamic friction forces enables nanometer-level feed positioning. An optimized mechanical structure effectively reduces friction losses and maintains positioning accuracy during long-term operation.
Drive: Supports multiple encoder feedback interfaces, including resolvers, incremental encoders, Sin/Cos encoders, EnDat, Hiperface, and others. Its software-configurable, flexible universal AC servo drive can function as a fieldbus slave, enabling a fully drive-based distributed motion control system.
02 Robotics Sector: Full Range of Core Components Enabling Domestic Substitution
Haozhi Industrial's strength lies in its “dual identity” — it is both a supplier of core functional components for machine tool manufacturers and a provider of core functional components for humanoid robots.
Harmonic Reducers: Through proprietary technological innovation, Haozhi Industrial's harmonic reducers achieve transmission accuracy of 30 arcsec, more than 66.7% higher in precision than comparable international harmonic reducers below size 17. Vibration peak values are reduced to 6 mm/s across the full speed range, 60% lower than comparable products. The measured noise level is only 57.2 dB. The innovative dual-flexspline harmonic reducer weighs only 0.32 kg, reducing weight by 68% compared with conventional harmonic reducers.
Integrated Joint Modules: Deeply integrating reducers, frameless torque motors, encoders, and other components, the modules reduce overall volume by 30% and weight by 25%, making them suitable for a variety of applications including collaborative robots, humanoid robots, and SCARA robots.
Six-Axis Force/Torque Sensors: Force-control accuracy of ≤0.1 Nm, combined with intelligent algorithms to enable precise and subtle force sensing.
Frameless Torque Motors, Encoders, Low-Voltage Drives, and Other Core Components: A full range of core components has achieved fully domestic substitution for the key functional components of humanoid robots.
