The face milling cutters Hepta 45° from Alesa impress with radially mounted reversible inserts, each with 14 (2×7) usable, sharp cutting edges. This guarantees an optimal price-performance ratio for every single indexable coulter.

The positive cutting geometries ensure low cutting forces and little heat input to the workpiece.

The very positive cutting philosophy not only leads to low cutting forces, but also enables higher productivity on modern machining centers. Depending on the material, there is less stress hardening and deformation due to stresses on the workpieces.

The users are fully convinced

It has spread all the way to the company Dynatec in Norway that Alesa tools can be used to solve the processing of demanding materials in the best possible way. The company works for the local oil and gas industry and manufactures components for their systems. The material is mostly 1.4404, an austenitic stainless steel with high corrosion resistance.

The large contact surfaces in the cutting seat of the Hepta front cutting head enable good heat transfer and thermal stability, even when working dry in this material. Together with the latest coatings, the very positively ground inserts show a very good service life and high productivity. To the full satisfaction of the production company, the best productivity and process reliability is achieved at a feed rate of 200 m/min and a feed rate of 0.0355 per tooth and an insertion depth of 4.0 mm. At these high cutting speeds, MQL is used for machining.

Low forces and processing temperatures

The Hepta face mill performs very well and causes less cutting force and temperature rise compared to other tools. This is very useful for achieving the difficult tolerance requirements for these items, as reported by the production engineers in Norway. SMM
