All-ceramic HSC roughing cutter

EFFICIENT MACHINING OF NICKEL-BASED ALLOYS

All-ceramic cutting tools made from optimised high-performance ceramics are used in the roughing of nickel-based alloys, especially Inconel, as well as cast iron materials. The demand for shorter machining times when working with these materials has led to the development of all-ceramic tools. Ceramic milling tasks can be carried out reliably with a cutting speed that is 20 to 30 times higher than with solid carbide. This results in a significant increase in productivity.

For applications with a particular focus on a shorter throughput time, the ATORN all-ceramic cutters boast incredible material removal rates thanks to high cutting speeds and exceptionally high feed rates. The all-ceramic tools are extremely lightweight and achieve maximum speed values without placing strain on the spindle bearings. The highest feed values can be achieved by means of a newly developed chip geometry.

There is also no risk of ceramic heating up, even in extreme cutting processes. The heat generated is dissipated exclusively via the chips. The cutting geometry and excellent finish of the tools result in the best cut edges. The extreme heat generated during the machining of all-ceramics affects the surface quality and roughness, which is why they are unsuitable for finishing machining.

PROPERTIES OF NICKEL-BASED ALLOYS

Nickel-based alloys are characterised by a high level of elongation, top strength and excellent cold deformability. Alloys with nickel produce a high-strength, corrosion-resistant material that is very difficult to machine.

High cutting temperatures above 800°C soften the material and make machining easier. Ceramic tools generate the required heat themselves through high cutting speeds, without suffering any damage.
