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
Learn how to choose the right milling picks for asphalt, concrete, and reclamation to cut downtime, protect holders, and lower cost per milled ton.
Slash fuel emissions and maximize RAP quality with advanced road milling bits. Learn how premium carbide tools ensure sustainable construction ROI.
In underground mining and tunnel construction, the performance of roadheader cutting picks directly affects excavation efficiency, cutting head maintenance, tool consumption, and overall operating cost. When a roadheader works continuously in abrasive rock, mixed ground, or hard geological formations, conventional cutting tools can experience rapid carbide wear, tip breakage, shank abrasion, or premature failure. For this reason, selecting the right roadheader picks is not simply a matter of matching dimensions. The carbide grade, pick geometry, steel body strength, brazing quality, surface wear protection, and cutting conditions all play an important role in determining tool performance. At Hengpu Laser, we focus on developing high-performance roadheader cutting picks and tunneling picks by combining advanced carbide technology with our proprietary laser-based metal-ceramic wear-resistant technology.
