(Reposted from 36Kr)Exclusive report from 36Kr: Hengpu (Ningbo) Laser Technology Co., Ltd. (hereinafter referred to as "Hengpu Laser") has completed a Series A financing round worth tens of millions of yuan, led by Shenzhen Tongchuang Weiye with participation from the Ningbo Angel Fund. The funds wi
In modern heavy-duty geotechnical operations—including asphalt pavement milling, deep foundation rotary drilling, underground coal mining, and tunneling—cutting picks operate under some of the most punishing tribological conditions in industry.A standard conical cutting tool (also known as a bullet bit, milling pick, or cutter tooth) consists of two primary metallurgical components:The Carbide Insert (Tip): Typically composed of Cobalt-bonded Tungsten Carbide (WC-Co), engineered for extreme hardness and rock-breaking capacity.The Tool Body (Shank): Forged from high-strength alloy steel (such as 42CrMo or equivalent), designed to absorb intense mechanical shock and transfer torque from the machine drum.While the tungsten carbide insert is built to withstand penetration forces, the underlying alloy steel body is significantly softer and inherently vulnerable to severe abrasion from high-velocity rock dust, sand, and asphalt aggregate. This vulnerability leads to a primary indust
Executive Summary: In cold planing and pavement recycling, road milling picks are critical wear parts directly impacting machine downtime, cutting efficiency, and cost per square meter. This comprehensive guide breaks down the key technical elements of premium milling teeth—including tungsten carbide tip formulations, forged body heat-treatment, and clamping sleeve dynamics. Readers will learn how to select the right pick geometry for different pavement conditions (asphalt, concrete, micro-milling) and implement site-proven maintenance strategies to prevent premature breakage, minimize toolholder wear, and maximize operational ROI.
Global infrastructure development is entering a new stage. Governments and private investors are financing roads, railways, tunnels, mines, water systems, energy facilities, and urban transportation networks to support economic growth and replace aging assets.
Cutting picks used in mining, road construction, tunneling, and foundation drilling must work under severe mechanical stress. During operation, the carbide tip may repeatedly strike hard rock, mineral inclusions, concrete, or uneven working surfaces.
How To Diagnose Rotary Drilling Pick Wear Patterns?In foundation drilling, Rotary Cutting Picks are continuously exposed to soil, gravel, sandstone, weathered rock, and hard mineral inclusions.
