Changes in the Future Lifecycle and Application Fields of Rotary Burrs Amid Rising Raw Material Prices

I. Impact on Production Lead Times

As a consumable product, rotary burrs typically see stable procurement rhythms and certain safety stock levels from downstream customers. However, the persistent rise in tungsten prices, coupled with tight raw material supply, has introduced uncertainty in the availability of some product types. To lock in costs, downstream users have begun placing orders earlier or extending order cycles. On the supply side, production capacity bottlenecks have further prolonged delivery lead times. Order backlog has stretched from several weeks to 2–3 months, posing new challenges to downstream customers' production planning.

II. Changes in Application Fields of Rotary Burrs

High-End Manufacturing: Stronger Demand Rigidity, Higher Price Tolerance

In high-end manufacturing sectors such as aerospace, military, and semiconductor equipment, demand for rotary burrs will not shrink in the short term due to rising tungsten prices. On the contrary, these sectors have extremely stringent requirements for machining accuracy and efficiency, and tool costs account for a relatively small share of total manufacturing costs, making customers more accepting of price increases.

Strong demand from high-end sectors including new energy vehicles, aerospace, and semiconductors has become a core growth driver for the industry. In 2025, the industry showed a trend of "rising first, then falling, and bottoming out to recover," reflecting companies' continued positive expectations for long-term development.

Shipbuilding: Sharply Rising Costs

Rotary burrs are key tools in shipbuilding for weld cleaning, burr removal, and finishing structural components. In the block assembly process of hulls, extensive welding generates a large amount of weld seams and flash, which rotary burrs are essential to remove. Additionally, finishing of flow-path components such as propeller blades and rudder blades relies on rotary burrs for smoothing and chamfering. The rising cost of raw materials means that the production cost of each rotary burr has increased in tandem.

For specialized vessel construction, where high-precision machining demands are far greater than for ordinary merchant ships, the usage frequency and consumption of rotary burrs are correspondingly higher. In these fields, machining quality and accuracy requirements are extremely stringent, substitutes are limited, and shipyards currently have little room for price negotiation.

Traditional Industries: Growing Substitution Pressure, Shrinking Application Scenarios

In traditional manufacturing sectors such as automotive parts, general machinery, and mold processing, rotary burrs face the greatest pressure. Downstream manufacturers already operate on thin profit margins. After the procurement cost of tools increased several times compared with the same period last year, many companies have begun seeking alternatives.
