The current (2026) market demand for broached parts is primarily driven by high-precision, high-volume components from sectors such as new energy vehicles, aerospace, and high-end equipment. The domestic broaching tool market size is projected to reach 5.05-5.21 billion yuan in 2026 (annual growth of approximately 6.8%-7.4%). However, broached parts themselves, as intermediate products, depend on downstream machine manufacturing and are not separately categorized. Core growth points are concentrated in typical broached structural parts such as splines, internal holes, and keyways.
Key downstream drivers: New energy vehicles (motor shafts, clutch hubs, gearbox splines/internal gears), aero-engines (turbine disc tenons, landing gear structural parts), and general machinery and molds (high-consistency mass-produced parts) are the three major demand sectors. Among them, the demand for broached parts related to new energy vehicles is projected to grow by over 25% in 2025-2026. Accelerated Domestic Substitution: The localization rate of broaching tools (directly related to machining capacity) in China is expected to reach approximately 55%–58% in 2025, and is projected to exceed 60% in 2026. Policy requires that the localization rate of domestically produced tools/machined parts in key areas (such as aero-engines and electric drives) be no less than 60%–85% (2027 target).
Irreplaceable Process: Broaching still possesses advantages in efficiency and consistency for high-volume (>50,000 pieces/year), IT7 or higher precision, and complex cross-section machining (such as involute splines and internal squares). Although partially replaced by milling/grinding/forging, it remains the preferred choice in transmission systems, hydraulic valve cores, and connectors.
