It provides tungsten steel end mills, milling inserts, turning inserts, grooving and parting inserts, drilling and boring inserts, multi-functional inserts, threading inserts, and other indexable inserts and their matching tool holders and tool holders. Furthermore, it has established long-term strategic partnerships with several well-known manufacturers, jointly developing R&D, design, and production teams, utilizing advanced equipment and continuously innovating technological capabilities. Committed to mutual cooperation and technical service-oriented approaches, it forms a mutually supportive industrial chain to solve various processing problems for manufacturing enterprises. In the field of precision manufacturing, the choice of cutting tools directly determines the lower limits of machining efficiency, cost, and quality. As the machining requirements of industries such as automotive, aerospace, and mold manufacturing become increasingly stringent, standard cutting tools often struggle to meet the combined demands of complex contours, high precision, and high efficiency. Non-standard coated CBN forming tools, as a high-precision tool integrating "customized design + superhard materials + advanced coatings," are becoming a key tool for more and more manufacturing companies to solve machining challenges. To understand its value, let's start with its name-"non-standard," "coating," "CBN," and "forming tool"-these four keywords themselves represent its four advantages over traditional cutting tools.
III. Coating Enhancement: Dual Thermal and Chemical Barriers Protection
If CBN material provides the "foundation" of hardness, then coatings build upon this foundation to achieve a leap in performance. Coatings act as both a chemical and thermal barrier in tooling: on the one hand, coatings reduce diffusion and chemical reactions between the tool and workpiece, thus inhibiting crater wear; on the other hand, coatings have excellent heat insulation properties, reducing the conduction of cutting heat to the tool substrate.
Coated CBN inserts have higher hardness, wear resistance, and impact toughness compared to uncoated CBN inserts. The new generation of multi-nano coating technology further improves wear resistance by 50%, and the coating hardness decays more slowly at high temperatures. Furthermore, coated tools have high surface hardness and a low coefficient of friction, which can increase cutting speed by 20%–70%. 0%, improving machining accuracy by 0.5-1 grade, reducing tool wear costs by 20%-50%, and increasing overall tool life by more than 2 times.
In practical applications, different colored coatings are suitable for different working conditions: golden yellow coatings (such as C20) have moderate performance and can be used for both continuous and interrupted machining; bronze coatings (such as C65, C03) are suitable for ultra-high-speed machining and continuous machining, extending tool life; grayish-brown coatings (such as C75) are suitable for medium- and low-speed cutting and strongly interrupted machining conditions. This multi-dimensional coating selection system allows non-standard coated CBN forming tools to accurately match various machining scenarios, achieving optimal performance.
IV. Forming Tools: An Integrated Solution of Efficiency and Precision
"Forming Tools" This is the final form of a non-standard coated CBN tool. Unlike traditional turning or milling cutters that require sequential cuts, forming tools directly correspond the tool profile to the final geometry of the workpiece, allowing for the shaping of multiple surfaces in a single cut.
It is precisely this integration of customized geometric profiles and the advantages of ultra-hard CBN material that makes it highly effective in many challenging machining applications. In aerospace parts manufacturing, customized CBN-based non-standard tools utilize their high hardness and thermal stability to solve the problem of rapid tool wear in the machining of high-temperature alloys (such as Inconel 718), maintaining cutting performance even above 600°C. In automotive parts processing, CBN-coated tools are widely used in powder metallurgy and automotive parts industries, providing stable cutting performance. Certain machining properties ensure the surface finish of the workpiece. It is worth mentioning that in practical applications, using CBN inserts to machine a certain part reduced machining time from 8 hours to less than 2 hours, quadrupling production efficiency and saving up to €100,000 annually. In the hard turning process of machining hardened steel gears, nanoscale edge passivation control technology reduced cutting resistance while maintaining edge strength, significantly extending tool life.
With its shaped tool structure, non-standard coated CBN shaped tools are particularly suitable for machining tasks with complex contours, numerous processes, and high precision requirements-precisely the most challenging and core challenge in modern precision manufacturing.
V. Comprehensive Benefits: Beyond the Tool Itself
If a single technological advantage isn't enough to impress manufacturing companies, then the comprehensive economic benefits of non-standard coated CBN forming tools are enough to make any production manager take notice.
In terms of production efficiency, the combined benefits of multi-process integration and high cutting speeds significantly reduce single-piece machining time. The CBN coating series, provided through innovative welding technology, combines excellent wear resistance and fracture toughness, demonstrating superior performance in a wide range of applications from continuous cutting to heavy interrupted cutting, which translates to a stable increase in machining cycle time. Regarding tool life, its stable and predictable long life reduces tool change frequency and sampling frequency, and its tool life is 5-25 times that of carbide tools. High wear resistance greatly reduces tool changes and grinding. The reduced number of cuts lowers tool management costs on the production floor. Regarding machining accuracy, the stable cutting performance of coated CBN forming tools ensures consistent workpiece surface finish, achieving mirror-like results with Rz=2.3μm or even higher.
They also offer significant advantages in environmental protection and economy. CBN tools can perform dry high-speed cutting without coolant, meeting increasingly stringent environmental requirements and reducing the cost of cutting fluid use and disposal. Although the unit price of CBN tools is higher, the cost per part is often lower – this return on investment is particularly significant when batch sizes are large enough and machining conditions are well-matched.
