ATORN RockTec PRO Hard machining
HPC milling cutter ATORN RockTec PRO: For maximum efficiency and durability in hard machining
With exclusively developed multilayer coating
ATORN RockTec PRO milling cutters are particularly suitable for machining steels < 1400 N/mm, < 55 HRC, < 60 HRC and < 65 HRC. The wide product range includes all geometries with the highest precision.
The new TiAlSiN multilayer coating, developed exclusively for ATORN, impresses with extreme hardness and minimal friction for optimum results.
Real power by nature
Hard machining is playing an increasingly important role in tool and mold making in particular and is replacing more and more time-consuming processes such as grinding or eroding. But in other areas too, components still need to be machined after hardening. This often presents milling tools with major challenges.
ATORN now offers highly specialized milling cutters for all conceivable milling applications. These high-performance tools are ideal for hard machining up to 65 HRC.
Thanks to their optimized geometry and the new, extremely hard multilayer coating, the ATORN RockTec PRO milling cutters ensure low friction and are therefore particularly resistant to wear. For example, they machine high-alloy tool steels such as 1.2379 at high cutting speeds of up to 250 m/min and feed rates of 0.001 to 0.15 mm.

Test winner
Just how good the new ATORN RockTec PRO milling cutters are is proven by the test victory in a comparative test carried out by the GFE Gesellschaft für Fertigungstechnik und Entwicklung Schmalkalden e.V. in which the ATORN RockTec PRO milling cutters prevailed against competitors in a hard milling test.
A tool steel 1.2379(X153 CrMo V12) with a hardness of 58 HRC was machined. Different solid carbide milling cutters were used to mill test paths with defined ap and ae. The ATORN RockTec PRO milling cutters showed the highest tool life in the overall result and thus came first in the overall evaluation.
