HSS-E & SOLID CARBIDE REAMING

The RE-AL precision reamers are presenting with the new fine hard surface coating ACUREA the modern precision reaming. It offers at the same time the very alternative to the carbide reamer.

The Chrome based Nano-composite hard surface coating ACUREA guarantees sharp reamer cutting edges, extended tool life as well as increased reaming qualities.

The ACUREA hard surface coating presents high thermal stability which prevents edge built up, allows high cutting speeds and increases wear resistance on steels, stainless steel, non ferrous metals, plastics, as well as on demanding special alloys, tempered and non magnetic steels, fibre reinforced plastics, high Si content aluminium, Titanium, Tantalum, Graphite.

High toughness and resistance to breakage and impact strength improve the repeatability of the required tolerances and prolong considerably the tool longevity. These unequivocal advantages increase the productivity and regularity of the reaming quality.

Application Example:

– Reamer: DIN 8089 Ø 6.15 mm
– Tool steel: X155CrVMo 12-1 DIN 1.2379
– Drilled hole: Ø 6.00 mm
– Reamed depth: 12 mm
– Vc = 25m/min, f = 0.15 mm/T
– Ø tolerance H6 = 9 µm
