In the world of underground excavation, a roadheader is only as powerful as its teeth. As the final point of contact with the rock face, the performance of the cutting teeth directly dictates the project’s speed and bottom line.
Underground work is a battle against extreme torque, high-frequency impacts, and abrasive erosion. Hengpu cutting picks are built to win that battle. Designed for maximum wear and pressure resistance, our tools effortlessly penetrate ultra-hard rock formations (up to f15 hardness).
The Hengpu S135, S260, and S360 series are the high-performance choice for major roadheader brands. Whether you operate Herrenknecht, Sandvik, Robbins, Komatsu, or Sany equipment, our teeth ensure seamless integration and peak productivity.
Mining: Comprehensive roadway excavation and development.
Infrastructure: High-efficiency tunneling for transport and water conservancy.
Urban Development: Precision, non-blasting excavation for municipal utility tunnels.
The Hengpu series roadheader cutting picks integrate a premium tungsten carbide alloy tip with a high-strength 42CrMo steel shank, which undergoes a quenching process for superior durability. Our patented innovation lies in the 3D laser-printed ceramic wear-resistant layer.
Advanced Material: Achieving a remarkable hardness of 68-70 HRC.
Superior Bonding: Utilizing a breakthrough metal-ceramic atomic bonding technology, the layer forms an exceptionally tight bond between the tip and shank. This significantly reduces wear at the critical junction point.
Enhanced Durability: The wear-resistant layer excels on hard geology, offering outstanding abrasion resistance.
Hengpu products have a lifespan more than three times that of ordinary products, effectively reducing the number of gear replacements and machine downtime, thereby significantly reducing the total operating cost of the entire project.
Hengpu is a pioneer in industrial wear resistance technology. We have overcome the long-standing industry challenge of balancing extreme hardness with exceptional toughness.
Technical Breakthrough: Our proprietary process solves the interface bonding difficulties between ceramic particles and the metal matrix. This enables 3D printing of wear layers using over ten types of ceramics (including Al₂O₃, ZrO₂, and SiC) with thicknesses up to 4mm.
Optimized Design: The laser-printed layer features 3D raised and recessed structures that ensure even surface wear distribution, precisely matching the designed service life.
Quality Assurance: The entire manufacturing process adheres to stringent international standards, with each tool certified under ISO9001:2008 and GJB9004B-2009 to guarantee stability and reliability.
Innovative Bionic Design: Inspired by pangolin scales, our proprietary wear-resistant technology creates a bionic structure where the ceramic layer fuses deeply (≥1mm) with the substrate. This represents a significant leap forward in material science.
Perfect Hardness-Toughness Balance: The atomic bonding technique merges the hardness of ceramics with the toughness of metal, delivering unparalleled performance, especially on hard geology.
Customizable Solutions: Available in various models (e.g., HPS135D-25TD, HPS135D-27TD, HPS260-30TD, HPS260-34TD, HPS360-30TD) with handle diameters of 38mm-42mm. Custom lengths are available to meet specific equipment requirements.
High-Temperature & Abrasion Resistance: The laser-printed ceramic layer withstands high temperatures and severe abrasion, extending tool life and ensuring superior performance in the most demanding construction environments.
Rapid & Reliable Supply: Manufactured in mature industrial workshop systems to ensure fast delivery without compromising on strict quality control.
Q: What is Hengpu Laser's background?
A: Hengpu Laser is a high-tech company founded in 2013 by a team of US-educated PhDs.
The founder, Dr. Liu Dejian, conducted extensive welding research at Ohio State University and has published numerous articles in international journals.
The company is a leader in China's ceramic 3D printing sector, specializing in the industrialization of industrial laser 3D printing technology. Recognized as a national-level "Specialized, Refined, and Unique" (Little Giant) enterprise.
Hengpu has successfully developed over 30 products for mining, subway tunnels, oil exploration, and infrastructure, establishing itself as a rapidly emerging brand in engineering cutting tools.
Q: Which machines are these roadheader cutting picks compatible with?
A: Suitable for tunneling machines, such as cantilever tunneling machines (EBZ series) for coal mines.
Q: What is the thickness of the wear-resistant layer?
A: Our 3D-printed ceramic wear-resistant layer can be up to 4mm thick, providing exceptional wear resistance.
Q: What are the product packaging specifications?
A: Products are primarily packed in boxes. For example, model HPS260-30TD is packed 10 pieces per box (23KG per box), with 60 boxes per full pallet. Please refer to the specific packaging parameters for each model.
Q: Do you offer custom services?
A: Yes, we provide personalized solutions tailored to your specific equipment and working condition requirements.
