In the machining process, a part is typically not machined to its final dimensions in a single operation but is completed step by step following a specific sequence. The common process flow is: Rough Machining → Semi-Finish Machining → Finish Machining. >>
Zhengzhou Berlt starts from the source of CBN materials to build a systematic quality control system. Through material structural design, sintering process stability control, crystal structure uniformity management, cutting-edge micro-surface quality engineering, and full-process manufacturing consistency control, a complete high-end tool quality assurance pathway is formed, achieving a systematic upgrade from “material-level control” to “engineering-level stability.” >>
CBN material possesses extremely high thermal stability, far exceeding that of diamond. It can maintain hardness and strength at cutting temperatures as high as 1000°C and above. This means it can inherently withstand the high temperatures generated by dry cutting without relying on cutting fluid for forced cooling. >>
From customer machining sites, common issues during the cutting process of hardened steel include chipping, fluctuating tool life, and poor machining consistency. Therefore, the core of selecting turning inserts for hardened steel lies not in single-cut performance, but in stability and controllability under long-term, batch processing conditions. >>
Cubic Boron Nitride is currently the second hardest man-made superhard material after diamond. Unlike diamond, CBN possesses excellent thermal stability at high temperatures (withstandable above 1200°C) and has extremely high chemical inertness towards ferrous elements. >>
Berlt CBN Hard Turning Inserts are precisely a mature solution developed to address this core need for hard steel machining. >>
"When other brands are still competing on hardness and price, Berlt has redefined the standard of 'ease of use' with an annual production capacity of 6 million inserts." — Zhengzhou Berlt In the field of hard turning, what truly >>
Choosing Berlt CBN inserts means wind power bearing processing no longer has to be a "tough nut to crack," but can instead easily shift into "high gear." We look forward to becoming your reliable, long-term, and mutually beneficial partner. >>

Zhengzhou Berlt CBN Inserts, as a pioneer in China's PCBN inserts industry, operates one of the country's largest CBN inserts production bases. Its products cover over 90% of the domestic market for hard and heavy-duty machining, with an annual production exceeding 6 million CBN inserts. Through continuous R&D on CBN raw materials and summarization of on-site machining experience, Berlt has developed specific CBN inserts grades suitable for turning different material properties based on their characteristics, meeting diverse machining objectives and requirements. >>
Zhengzhou Berlt has been deeply engaged in the R&D and production of CBN inserts for over 20 years. Continuously researching and developing CBN tool materials matching the properties of the processed materials, it has developed a series of cubic boron nitride tool material grades for materials like cast iron and hardened steel, such as the BTS2800 series, BTS3800 series, BTS3100 series, BTS6000 series, BTS6500 series, etc., which can meet different machining application requirements. >>
