"While other brands are still competing on hardness and price, Berlt has already redefined the 'efficiency' standard with an annual production capacity of 6 million pieces." — Zhengzhou Berlt
In the field of CBN (Cubic Boron Nitride) superhard cutting tools, Zhengzhou Berlt is not only the pioneer of domestic CBN inserts but also a setter of industry standards. Since its establishment in 2002, Berlt has achieved an annual production capacity of 6 million CBN inserts, capturing over 70% of the domestic market share in hard turning applications, thereby becoming a benchmark in the CBN tool industry.
Core Strength: Full-Chain Control from Materials to Processes
The core competitiveness of Zhengzhou Berlt's CBN inserts stems not only from over 20 years of continuously optimized processes but also begins with absolute control over the boron nitride raw materials. Unlike other CBN insert manufacturers, Berlt deeply understands the importance of the raw material supply chain in the entire production process. It has successively guided or taken control of several raw material manufacturing enterprises, ensuring the purity and crystalline structure of the boron nitride materials from the source, truly achieving "Berlt products are guaranteed to be of superior quality."
Technical Depth: Dual Barriers of Patents and Standards
In 2002, Berlt produced China's first solid polycrystalline cubic boron nitride insert. In 2004, Berlt was the first in China to obtain a patent authorization for CBN inserts, breaking the foreign technological monopoly. Before the second half of 2009, Berlt was the "only" domestic enterprise providing rough machining CBN tools.
Over more than 20 years of development, Berlt has successively undertaken national key industry-university-research collaboration projects and scientific research initiatives for CBN material products. Simultaneously, it has participated in formulating several industry standards for superhard tools and products, establishing dual barriers of patents and standards.
Application Scenarios: Practical Validation from Cast Iron to Hard Steel
Through continuous R&D on CBN raw materials and summarization of on-site machining experiences, Zhengzhou Berlt has developed specific CBN tool grades suitable for turning different workpiece materials based on their characteristics. Whether in terms of wear resistance, impact toughness, or machining efficiency, these outperform inserts from other brands.
For example, the BTS2800 and BTS3800 series CBN tool materials, developed for cast iron components, balance the toughness and wear resistance of the tool, finding wide applications in areas like rollers, industrial pumps, and automotive brake discs. The BTS6000 and BTS6500 series CBN tool materials, developed for hardened steel components, ensure high hardness, strength, and wear resistance while improving the impact resistance of the CBN tools, meeting the demands for interrupted cutting of hard steel workpieces.
Service Closed Loop: Integrated Solutions from Inserts to Processes
Adhering to the philosophy of "providing tool materials for manufacturers, providing tool products for distributors, and providing tool services for end-users," Berlt not only supplies stable, high-performance raw materials to upstream tool manufacturers but also offers diversified and flexibly customizable products to midstream distributors. More importantly, it provides in-depth technical services covering the entire machining process for end-users.
Materials — Products — Services: this approach has not only made Berlt one of the most efficient CBN insert brands but is also the key to its sustained leadership and benchmark status in the superhard tool industry. If you encounter challenges with CBN inserts, please feel free to contact Berlt.
