Road construction and rehabilitation projects face costly downtime caused by premature wear of milling bit steel bodies. Although tungsten carbide tips remain functional, erosion from abrasive asphalt, crushed concrete and dust wears out the steel bit body, forcing full tool replacement. This results in frequent machine shutdowns, wasted carbide material, unstable milling quality and increased operating expenses. Hengpu (Ningbo) Laser Technology is re-engineering the product to solve this root problem instead of partial fixes.
Abstract: Holders and milling drums serve as core components for road milling machines. They directly govern milling quality and constitute the dominant share of daily machine‑operating costs. Against the backdrop of persistently rising global hard‑alloy raw‑material prices and record‑high pick procurement costs, genuine cost reduction cannot be achieved merely by squeezing unit‑purchase prices. Leveraging proprietary cermet laser‑cladding technology, Ningbo Hengpu Laser Technology Co., Ltd. has developed high‑performance road‑milling picks and matched washer systems fully compatible with OEM‑spec HT22 quick‑change holders. By optimizing pick‑rotation conditions, mitigating abnormal wear and extending holder service life, our solutions help contractors boost milling efficiency, cut consumable consumption and reduce downtime, enabling transition from simple component procurement to full‑lifecycle cost control. Starting from real‑world job‑site pain points, this article analyzes the root
