In turning operations, annular grooves such as positioning grooves and circlip grooves on shafts are commonly machined. These grooves are usually shallow and narrow with high requirements for dimensional accuracy and profile tolerance. Besides, grooving generates high cutting force,poor clamping positioning or insufficient system rigidity often causes insert shifting, chatter, chip entanglement and insert breakage.
Based on market demands, Worldia has expanded product applications on the basis of existing superhard grooving tools and developed a variety of carbide grooving products. This case introduces the W‑Notch carbide grooving insert optimized for shallow groove machining.
Features of Worldia W‑Notch Series Carbide Grooving Tools
■ Reliable positioning: Three wide positioning surfaces ensure high positioning precision of inserts.
■ High clamping rigidity: The top‑clamped V‑shaped positioning surface enables stable clamping and allows multi‑direction turning.
■ Sufficient cooling: High‑pressure internal coolant design improves chip breaking performance.
■ Multiple insert geometries: A wide range of high‑quality edge preparations and groove geometries for broad applications.
■ Diverse insert grades: Rich substrate options to adapt to shallow grooving under various working conditions.

◎This case involves continuous mass production of workpieces. The customer required improved tool stability and reduced tooling cost. Worldia adopted W‑Notch series PVD coated carbide inserts, achieving 20% longer tool life and 20% reduction in tooling cost.
◎According to workpiece material, groove dimension and process characteristics, Worldia selected inserts with sharp edge and excellent chip‑breaking geometry, together with versatile WHP1061 carbide grade. This grade delivers good wear resistance, and the PVD coating further enhances wear performance and tool life.
◎Worldia W‑Notch series carbide grooving tools share the same toolholders with superhard grooving tools, expanding the application scope of original superhard grooving tools. Furthermore, W‑Notch series is available in multiple insert grades and geometries, suitable for various shallow grooving applications on cast iron, steel and stainless steel. Non‑standard customization available.
