　　Core viewpoint:

　　2025-2026年是人形機器人量產元年，絲杠作為占整機成本19%的核心傳動部件，正迎來從"0到1"的突破。特斯拉Optimus明確采用14個行星滾柱絲杠的方案，定義了主流技術路徑，國產替代空間巨大。01主題界定與核心驅動力

　　2025-2026 is the first year of mass production for humanoid robots, and the screw, as the core transmission component that accounts for 19% of the overall cost, is experiencing a breakthrough from "0 to 1". The Tesla Optimus clearly adopts a solution of 14 planetary roller screws, defining the mainstream technology path, and there is huge room for domestic substitution. 01 Theme Definition and Core Driving Forces

　　主題定義本報告聚焦的"人形機器人絲杠環節"，是指為人形機器人提供核心直線傳動功能，將旋轉運動精確轉化為線性運動的精密機械部件及其上下游產業鏈。核心邊界：以行星滾柱絲杠（用于軀干主關節）和微型滾珠絲杠（用于靈巧手）為主，涵蓋從特種鋼材、精密加工設備到絲杠成品制造的全過程。

　　The theme definition of this report focuses on the "humanoid robot screw link", which refers to the precision mechanical components and their upstream and downstream industrial chains that provide core linear transmission functions for humanoid robots, accurately converting rotational motion into linear motion. Core boundary: Mainly using planetary roller screws (for trunk main joints) and micro ball screws (for dexterous hands), covering the entire process from special steel, precision machining equipment to finished screw manufacturing.

　　三大核心驅動力

　　Three core driving forces

　　① 技術突破與產品定義以特斯拉Optimus為代表的龍頭產品，明確將行星滾柱絲杠作為線性執行器的標準解決方案。AI大模型在運動控制上的快速迭代，顯著提升了機器人本體的運動能力與智能化水平。

　　① Technological breakthroughs and product definitions are represented by Tesla Optimus, a leading product that explicitly uses planetary roller screws as the standard solution for linear actuators. The rapid iteration of AI models in motion control has significantly improved the motion capability and intelligence level of the robot body.

　　② 重大產業與成本拐點臨近2025-2026年被廣泛視為量產元年。特斯拉、小鵬、優必選等整機廠商明確了量產時間表，需求將從"臺"級躍升"萬臺"乃"百萬臺"級。規模化將推動工藝從磨削向"以車代磨"、旋風銑等工藝演進，帶來顯著降本空間。

　　② Major industries and cost inflection points are approaching, and 2025-2026 is widely regarded as the first year of mass production. Tesla, Xiaopeng, Ubiquitous and other whole machine manufacturers have clarified their production schedules, and demand will jump from the "unit" level to the "tens of thousands" or even "millions" level. Scale up will promote the evolution of processes from grinding to efficient processes such as "replacing grinding with vehicles" and whirlwind milling, bringing significant cost reduction opportunities.

　　③ 強力政策與自主可控需求工業母機及高端裝備的自主可控是戰略方向。絲杠作為數控機床的核心部件，其高端市場長期被外資壟斷。在政策推動下，國產化替代與在人形機器人賽道上的彎道超車形成強大合力。02產業鏈解構與技術路徑圖 產業鏈三級梯隊上游材料與設備高性能合金鋼（如軸承鋼）：熱處理工藝直接影響絲杠壽命與承載能力

　　③ Strong policies and independent controllable demand for industrial mother machines and high-end equipment are national strategic directions. As the core component of CNC machine tools, the screw has long been monopolized by foreign investment in its high-end market. Under policy promotion, domestic substitution and overtaking on the curve of the humanoid robot race have formed a strong synergy. 02 Industrial Chain Deconstruction and Technology Roadmap: Upstream Materials and Equipment High Performance Alloy Steel (such as Bearing Steel) in the Third Tier of the Industrial Chain: Heat Treatment Process Directly Affects the Life and Load Capacity of the Screw

　　高精度加工設備：高端磨床、旋風銑床、數控車床，目前仍依賴進口▼中游 ★核心絲杠制造行星滾柱絲杠：用于軀干主關節，技術壁壘

　　High precision machining equipment: high-end grinding machines, cyclone milling machines, CNC lathes, currently still relying on imports ▼ midstream ★ core screw manufacturing planetary roller screws: used for trunk main joints, with the highest technical barrier

　　微型滾珠絲杠：用于靈巧手，精度要求極高

　　Micro ball screw: used for dexterous hands, with extremely high precision requirements

　　集中了材料學、精密加工、熱處理、檢測等綜合技術壁壘▼下游集成與應用絲杠與電機、傳感器、軸承等集成形成線性執行器模組，終裝配于人形機器人本體，應用于工業制造、商業服務、家庭護理等場景。 四大加工工藝路徑對比 磨削工藝當前主流特點：使用砂輪進行精加工

　　Integrating materials science, precision machining, heat treatment, testing and other comprehensive technical barriers, downstream integration and application of screw and motor, sensor, bearing and other components to form linear actuator modules, which are ultimately assembled into humanoid robot bodies and applied in industrial manufacturing, commercial services, home care and other scenarios. Comparison of four major machining process paths: The current mainstream feature of grinding technology is the use of grinding wheels for precision machining

　　優勢：精度，可達P0/P1級，表面質量好

　　Advantages: Highest accuracy, up to P0/P1 level, good surface quality

　　劣勢：效率低，設備投資大（進口磨床上千萬），砂輪耗材成本高

　　Disadvantages: Low efficiency, large equipment investment (tens of millions of imported grinding machines), high cost of grinding wheel consumables

　　階段：高精度絲杠，已成熟應用 旋風銑快速崛起特點：采用旋轉刀具進行銑削

　　Stage: High precision lead screw preferred, mature application, rapid rise of whirlwind milling features: using rotary cutting tools for milling

　　優勢：效率較高，精度與效率平衡性好

　　Advantages: High efficiency, good balance between accuracy and efficiency

　　劣勢：高端多軸設備依賴進口，刀具設計有門檻

　　Disadvantage: High end multi axis equipment relies on imports, and there are thresholds for tool design

　　階段：降本提效的重要方向 硬車（以車代磨）技術突破期特點：用超硬刀具進行車削

　　Stage: An important direction for cost reduction and efficiency improvement. Hard turning (replacing grinding with turning) technology breakthrough stage. Characteristics: Using superhard cutting tools for turning

　　優勢：加工效率高（約為磨削的2-3倍），設備成本相對較低

　　Advantages: High processing efficiency (about 2-3 times that of grinding), relatively low equipment cost

　　劣勢：對刀具剛性、機床穩定性要求極高，工藝成熟度待提升

　　Disadvantage: The requirements for tool rigidity and machine stability are extremely high, and the process maturity needs to be improved

　　階段：國內多家廠商研發 軋制大批量標準件特點：通過塑性變形成型螺紋

　　Stage: Multiple domestic manufacturers focus on developing and rolling large quantities of standard parts. Characteristics: forming threads through plastic deformation

　　優勢：效率極高，材料利用率高，成本低

　　Advantages: extremely high efficiency, high material utilization rate, low cost

　　劣勢：精度較低，難以滿足機器人關節的高要求

　　Disadvantage: Low accuracy, difficult to meet the high requirements of robot joints

　　階段：適用于中低精度、大批量標準件 未來趨勢："磨削保證精度+車/銑提升效率"的混合工藝或將成為主流。短期內掌握磨削工藝的企業具備量產交付能力；中長期看，在旋風銑或硬車工藝上實現高精度、高穩定量產的企業將贏得成本優勢。 價值鏈識別核心環節（高附加值、高技術壁壘）：中游的絲杠制造，特別是行星滾柱絲杠的螺紋精密加工。其價值凝聚了材料、設備、工藝Know-how和檢測技術，毛利率潛力。關鍵瓶頸環節（短期供給剛性）：上游的高端加工設備（如高端磨床）和高質量原材料。設備的交貨周期和材料的性能穩定性，是制約絲杠產能快速擴張和性能一致性的關鍵瓶頸。03價值量分布與動態演變分析 靜態價值分布152.6億2030年全球市場規模（美元）

　　Stage: Suitable for medium to low precision and large-scale standard parts. Future trend: The hybrid process of "grinding ensures accuracy+turning/milling improves efficiency" may become mainstream. Enterprises that have mastered grinding technology in the short term have the ability to mass produce and deliver; In the medium to long term, enterprises that achieve high-precision and high stability mass production in whirlwind milling or hard turning processes will win cost advantages. The core link of value chain identification (high added value, high technological barriers): midstream screw manufacturing, especially precision machining of planetary roller screw threads. Its value embodies materials, equipment, process know-how, and testing technology, with the highest gross profit margin potential. Key bottleneck link (short-term supply rigidity): Upstream high-end processing equipment (such as high-end grinding machines) and high-quality raw materials. The delivery cycle of equipment and the stability of material performance are key bottlenecks that restrict the rapid expansion of screw production capacity and performance consistency. 03 Value Distribution and Dynamic Evolution Analysis Static Value Distribution 15.26 billion Global Market Size in 2030 (USD)

　　19%絲杠價值量占比

　　19% of screw value proportion

　　500億+2030年絲杠市場規模（人民幣）市場規模：據Markets and Markets預測，2030年全球人形機器人市場規模約152.6億美元。絲杠作為價值量占比約19%的核心部件，多家機構測算2030年僅人形機器人帶來的行星滾柱絲杠市場規模有望達到數百億元人民幣級別（東吳證券測算超450億元，中信建投測算超500億元），較傳統工業市場呈幾何級數增長。 毛利率區間：由于當前處于產業化早期，具備量產能力的廠商少，競爭格局好，預計絲杠產品特別是行星滾柱絲杠的毛利率處于較高水平。參考精密傳動行業，規模化量產初期毛利率可達40%-50%甚更高。隨著后續競爭加劇和工藝優化，毛利率將逐步回落并穩定在合理區間。 動態價值遷移四大趨勢1技術迭代催生新價值環節若"以車代磨"或"旋風銑"工藝在高精度絲杠加工上取得突破并成為主流，那么高性能超硬刀具、高端數控車床及旋風銑設備的價值和需求將大幅提升，相關設備與耗材供應商將受益。

　　50 billion+2030 screw market size (RMB) market size: According to Markets and Markets' forecast, the global humanoid robot market size will be approximately 15.26 billion US dollars by 2030. As a core component that accounts for about 19% of the value, the screw is expected to reach a market size of tens of billions of yuan in planetary roller screws brought by humanoid robots alone by 2030, according to multiple institutions (estimated by Dongwu Securities to exceed 45 billion yuan and CITIC Securities to exceed 50 billion yuan), showing geometric growth compared to the traditional industrial market. Gross profit margin range: Due to the current early stage of industrialization, there are few manufacturers with mass production capabilities, and the competitive landscape is good, it is expected that the gross profit margin of screw products, especially planetary roller screws, will be at a relatively high level. Referring to the precision transmission industry, the initial gross profit margin for large-scale production can reach 40% -50% or even higher. With the intensification of competition and process optimization in the future, the gross profit margin will gradually decline and stabilize within a reasonable range. The four major trends of dynamic value transfer are: 1. Technological iteration generates new value links. If the "car instead of grinding" or "whirlwind milling" processes make breakthroughs in high-precision screw machining and become mainstream, the value and demand for high-performance superhard cutting tools, high-end CNC lathes, and whirlwind milling equipment will be greatly increased, and related equipment and consumables suppliers will benefit.

　　2產業化進程中的需求彈性導入期：高精度加工設備需求迫切；

　　The introduction period of demand elasticity in the industrialization process: the urgent demand for high-precision processing equipment;

　　放量期：具備大規模、一致性生產能力的絲杠制造商以及PEEK等輕量化材料供應商將迎來巨大彈性。

　　High volume period: Screw manufacturers with large-scale and consistent production capabilities, as well as lightweight material suppliers such as PEEK, will experience tremendous flexibility.

　　3供需格局與階段性溢價

　　3 Supply and demand patterns and phased premiums

　　在需求突然爆發時，螺紋磨床等高端設備因其交付周期長（通常1年以上），將成為緊俏的瓶頸資源，設備廠商及已提前鎖定設備產能的絲杠企業將獲得階段性溢價。4國產替代實現價值轉移在行星滾柱絲杠這一被Rollvis、GSA等歐洲企業壟斷（2022年CR4約78%）的"卡脖子"環節，國內企業一旦實現技術突破和批量供貨，將直接承接巨大的價值轉移。國產化率每提升一個百分點，都意味著數億乃數十億元的市場份額重新分配。

　　When demand suddenly erupts, high-end equipment such as thread grinders will become the most scarce bottleneck resource due to their long delivery cycle (usually over 1 year). Equipment manufacturers and screw enterprises that have already locked in equipment production capacity in advance will receive a phased premium. In the "bottleneck" link of planetary roller screw, which is monopolized by European companies such as Rollvis and GSA (with a CR4 of about 78% in 2022), domestic enterprises will directly undertake huge value transfer once they achieve technological breakthroughs and bulk supply. Every one percentage point increase in localization rate means a redistribution of market share worth billions or even billions of yuan.

　　彈性邏輯：彈性。秦川作為國內宣稱量產行星滾柱絲杠的國企，技術卡位獨特；恒立液壓憑借液壓領域積累的精密制造與客戶優勢，大規模資本投入線性驅動器，確定性較強。特色工藝與型供應商代表公司：雙林股份（收購無錫科之鑫）、貝斯特、五洲新春、北特科技、震裕科技、嶸泰股份特征：在特定工藝路徑（如旋風銑、硬車）或上游關鍵環節（設備、材料）具備深厚積累

　　Elastic logic: The highest elasticity. As the only state-owned enterprise in China that claims to mass produce planetary roller screws, Qinchuan has a unique technical positioning; Hengli Hydraulic relies on its accumulated precision manufacturing and customer advantages in the hydraulic field, with large-scale capital investment in linear drives and strong certainty. Representative companies for characteristic processes and expert suppliers: Shuanglin Co., Ltd. (acquired Wuxi Kezhixin), Best, Wuzhou Xinchun, Beite Technology, Zhenyu Technology, Rongtai Co., Ltd. Features: has a deep accumulation in specific process paths (such as whirlwind milling, hard turning) or upstream key links (equipment, materials)

　　彈性邏輯：彈性大，取決于技術路徑驗證。雙林通過收購掌握反向絲杠磨床技術，具備"設備+產品"協同優勢。貝斯特、五洲新春從汽車零部件延伸，工藝同源，具備成本和規模化潛力。產能快速布局與生態賦能者代表公司：南方精工、力星股份特征：通過資本運作或快速擴產搶占賽道，或為生態內核心廠商提供支撐

　　Elastic logic: The elasticity is large and depends on the verification of the technical path. Shuanglin has acquired the technology of reverse screw grinding machine through acquisition, possessing the synergistic advantage of "equipment+product". Best and Wuzhou New Year extend from automotive parts, with the same technology and potential for cost and scale. Representative companies for rapid production capacity layout and ecological empowerment: Southern Precision Industry and Lixing Co., Ltd. Characteristics: Seize the track through capital operation or rapid expansion of production, or provide support for core manufacturers within the ecosystem

　　彈性邏輯：高彈性，但需驗證。此類公司擴產激進（如北特科技投資18.5億建基地），若產能消化順利則彈性巨大，反之則有風險。其成功高度依賴下游客戶定點進展。產業鏈配套與隱形特征：專注于絲杠上游的軸承、滾動體、精密結構件等細分領域

　　Elastic logic: High elasticity, but requires verification. Such companies are aggressively expanding their production (such as Beite Technology investing 1.85 billion yuan to build a base). If the capacity digestion is smooth, there will be huge flexibility, otherwise there will be risks. Its success is highly dependent on the targeted progress of downstream customers. Industrial chain matching and hidden champion features: Focusing on segmented fields such as bearings, rolling elements, precision structural components, etc. upstream of the screw

　　彈性邏輯：確定性較高，彈性中等。作為"賣鏟人"，受益于行業整體擴容，需求波動小于整機制造商，但單車價值量相對較低。 上市公司深度對比秦川機床000837.SZ產業鏈環節：中游：行星滾柱絲杠、RV減速器技術路徑：自研P0級磨床，掌握核心磨削工藝；國內量產行星滾柱絲杠報道核心客戶：適配特斯拉Optimus、華為機器人；軍工領域高市占率投資邏輯：稀缺的"設備+工藝+產品"全鏈條隊，技術卡位。

　　05綜合研判與風險提示

　　05 Comprehensive analysis and risk warning

　　投資時鐘與階段判斷綜合來看，人形機器人絲杠產業正處從概念導入期向成長初期過渡的關鍵階段。其特征是：技術路線初步明確但工藝仍在優化，龍頭產品已定義需求，多家企業完成樣品送樣，少數企業實現小批量供貨，大規模量產訂單即將落地。

　　From the perspective of investment clock and stage judgment, the humanoid robot screw industry is currently in a critical stage of transition from the concept introduction period to the early growth stage. Its characteristics are: the technical route is initially clear but the process is still being optimized, the requirements for leading products have been defined, multiple companies have completed sample delivery, a few companies have achieved small batch supply, and large-scale production orders are about to land.

　　這是投資產業鏈核心環節的"左側布局期"。 標的排序基于"確定性優先，兼顧彈性"原則

　　This is the best 'left side layout period' for investing in the core links of the industrial chain. The recommended ranking of targets is based on the principle of "giving priority to certainty while considering flexibility"

　　恒立液壓、秦川機床邏輯：前者具備從成功產業向更精密產業擴展的極高確定性和綜合優勢；后者具備稀缺的技術與產品卡位，且背靠國資，資源整合能力強。

　　Preferred options are Hengli Hydraulic and Qinchuan Machine Tool Logic: The former has a high degree of certainty and comprehensive advantages in expanding from a successful industry to a more precise industry; The latter has the most scarce technology and product positions, and is backed by state-owned assets with strong resource integration capabilities.

　　次選雙林股份、貝斯特、五洲新春邏輯：雙林"設備+部件"的垂直整合模式在量產階段潛力巨大；貝斯特勝在工藝穩健、客戶基礎好；五洲新春已通過新劍傳動切入特斯拉供應鏈，定增擴產彈性大。

　　The second choice is Shuanglin Co., Ltd., Best, and Wuzhou New Year's logic: Shuanglin's vertical integration mode of "equipment+components" has great potential in the mass production stage; Bestsheng has stable craftsmanship and a good customer base; Wuzhou New Year has entered Tesla's supply chain through New Sword Transmission, with great flexibility in expanding production through private placement.

　　跟蹤震裕科技、北特科技、浙江榮泰邏輯：這些公司布局明確且積極，需密切跟蹤其客戶定點進展、產能落地情況及量產產品的良率與成本數據，以驗證其邏輯。浙江榮泰是特斯拉靈巧手微型滾珠絲杠核心供應商。關鍵風險提示技術路線迭代風險特斯拉等龍頭公司未來可能因技術突破（如磁懸浮關節）而改變執行器方案，導致對絲杠的需求減弱或消失。

　　Tracking Zhenyu Technology, Beite Technology, and Zhejiang Rongtai Logic: These companies have clear and proactive layouts, and need to closely track their customers' progress, production capacity implementation, and yield and cost data of mass-produced products to verify their logic. Zhejiang Rongtai is the core supplier of Tesla's dexterous hand micro ball screw. Key Risk Warning: Technological Route Iteration Risks. Leading companies such as Tesla may change their actuator solutions in the future due to technological breakthroughs (such as magnetic levitation joints), leading to a decrease or disappearance in demand for lead screws.

　　產業化進度不及預期風險人形機器人的量產涉及復雜的技術、成本和問題，若整機量產進度大幅推遲，將導致上游絲杠"需求失速"。競爭加劇與盈利風險當前的高毛利率具有階段性。

　　The industrialization progress is slower than expected, and the mass production of humanoid robots involves complex technical, cost, and safety issues. If the overall mass production progress is significantly delayed, it will lead to a "demand stall" for upstream screw rods. The current high gross profit margin due to intensified competition and profit risks is phased.

　　一旦國產化突破，大量資本涌入可能導致行業競爭急劇惡化，引發戰，侵蝕企業盈利能力。供應鏈瓶頸與成本風險高端加工設備、特種鋼材的供應緊張和上漲，可能制約企業擴產速度并抬高成本，影響交付和利潤。

　　Once localization breaks through, a large influx of capital may lead to a sharp deterioration of industry competition, trigger price wars, and erode corporate profitability. Supply chain bottlenecks and cost risks. The tight supply and rising prices of high-end processing equipment and special steel may constrain the expansion speed of enterprises and increase costs, affecting delivery and profits.
