en.Wedoany.com Reported - TaeguTec has introduced the new VNGX-ST chipbreaker insert in its Rhino-Turn product line, a double-sided four-corner insert designed for heavy turning applications. This product aims to meet the growing demand for tooling solutions in demanding machining operations, enhancing productivity and extending tool life while reducing carbide usage to lower costs.

The VNGX-ST insert joins TaeguTec's recently launched ST chipbreaker series, which has established a strong performance reputation in heavy material removal operations. By integrating the ST geometry into the VNGX platform, TaeguTec offers a cutting solution that reduces machining time while maintaining surface quality and dimensional accuracy.

This insert is compatible with Rhino turning tool holders, and its four indexable cutting edges provide cost advantages. Compared to traditional two-edge heavy turning insert designs, the number of effective cutting edges is doubled, directly reducing tool costs, decreasing tool change frequency and downtime, and improving machine utilization. The VNGX-ST features a 35° diamond geometry but can handle cutting depths up to 3mm thanks to its advanced chipbreaker design, covering operations from finishing to heavy roughing, reducing the need for tool changes and simplifying the production process.

A key innovation in the insert design is the 25° high rake angle, which generates lower cutting forces during machining. Reduced mechanical stress minimizes vibration, thereby allowing higher cutting parameters and better surface finish. Workpiece accuracy benefits from reduced deformation, while the cutting edge operates under lower thermal and mechanical loads, extending tool life. TaeguTec recommends this insert for Swiss-type sliding headstock turning centers equipped with servo oscillation functions, such as Citizen UK's LFV software or Star's HFT or SCP software. This combination optimizes chip breaking and maintains the surface quality required for precision turned parts.

TaeguTec offers six VNGX-ST insert models, available with either sharp edge or micro-honed edge treatments, suitable for workpiece materials such as steel, stainless steel, and more challenging alloys. The series includes PVD-coated grades TT9020 and TT4430, designed to resist wear and extend tool life in demanding production environments.
