Indexable insert milling cutter Spinworx® HT

faceroughingplunge

Overview
Spinworx® HT expands the Spinworx® indexable tooling system with a variant engineered for high thermal and mechanical loads. The system targets short cycle times and process reliability, enabling stable, cost‑effective machining under extreme conditions. Spinworx® HT supports high cutting speeds, high material removal rates and elevated feeds to reduce production time while maintaining long tool life. Suitable for workpieces in titanium, duplex and nickel‑base alloys as well as all stainless steels.

Self-rotating cutting insert
Spinworx® indexable cutters use self‑rotating inserts embedded in the cutter body. A rear‑inserted pin secures the insert and each insert features a raceway to ensure constant rotation. Full utilization of the cutting edge produces uniform circumferential wear and removes the need for manual indexing, increasing uptime and extending service life. Depending on milling conditions, self‑rotating inserts allow higher chip volumes and continuous production.

Cutter body
The cutter body is designed from a newly developed high‑tech material with near‑monolithic properties to maximize stability. Its geometry promotes optimal chip evacuation—especially in pockets and grooves—and the rounded outer contour prevents chips from adhering to the tool, improving process security and surface quality.

Processing types

• Roughing
• Finishing
• Plunge milling (including angled and circular/helical strategies)
