UHD Superhard Cutting Solutions
UHD integral integral brazed CBN insert combine a CBN cutting tip with a cemented carbide substrate through double-sided vacuum integral welding. This structure is designed to support a stable metallurgical bond, improve usable cutting-edge utilization, and provide a dependable option for hard turning and high-load machining.
The insert is designed for hard turning, interrupted cutting, and other high-load metal-cutting conditions. Its CBN cutting tip is firmly joined to a cemented carbide substrate by a double-sided vacuum integral welding process. Compared with conventional high-frequency or single-sided welded structures, this configuration focuses on maintaining bonding stability under heat, cutting load, and thermal cycling.
For production users, the value of the design is not limited to initial cutting performance. It also concerns cutting-edge utilization, tool-change frequency, process consistency, and the total cost of machining each component.
The CBN tip and carbide substrate are joined through a double-sided vacuum welding process. The structure is intended to reduce bonding-related failure risks in high-temperature, high-load, and thermally variable cutting conditions.
The double-sided configuration increases the number of usable cutting edges per insert. This can help reduce tool changes and make insert consumption easier to manage in batch production.
The cemented carbide substrate provides a resilient foundation for higher cutting loads. Within suitable cutting parameters, the insert can support roughing, semi-finishing, and finishing requirements according to the selected grade.
The inserts are available in common ISO geometries and can be used with compatible standard toolholders. Final suitability depends on the machine, workholding, insert geometry, workpiece, and cutting parameters.

Correct insert selection depends on the workpiece material, machine rigidity, workholding, cutting parameters, and required surface finish. This product is not intended as a universal solution for every turning operation.
Materials generally unsuitable for this insert include:
The insert is not recommended for:
The insert can be used on conventional CNC lathes and hard-turning machines with suitable toolholders. Its application basis is generally compatible with standard production equipment, while special conditions—such as severe interrupted cutting, complex clamping, limited machine rigidity, or extreme cutting parameters—should be reviewed before production use.
As an integrated manufacturer and international supplier, Henan UHD Superhard Cutting Tools Co., Ltd. supports standard CBN and PCD tooling as well as selected non-standard customization. UHD can work with B2B customers to evaluate the workpiece material, insert grade, geometry, machine setup, and production objective before confirming an appropriate cutting solution.
For hard-turning applications where bonding stability, double-sided cutting-edge utilization, and process consistency are important, UHD integral welded CBN inserts provide a structured option for technical evaluation. Final performance should be verified against the specific workpiece, machine, tooling system, and cutting parameters.
