Versatile milling cutter unveiled

Dormer Pramet’s Econ LN has been designed as a cost-effective, versatile milling option that is capable of supporting numerous operations in most materials while still producing high levels of surface finish.

Positive axial geometry on this universal 90° cutter allows for lower cutting forces and smoother machining in steel, cast iron, stainless steel, non-ferrous metals and hardened materials.
Econ LN cutters offer internal cooling capability close to the cutting edges, a combination of wiper inserts, secure clamping and reduced power consumption. Compatible with the cutter are Dormer Pramet’s LNGX 12 and LNMU 16 inserts, which provide four cutting edges. LNGX 12 inserts support helical interpolation, ramping and progressive plunging, while LNMU 16 inserts are said to deliver long tool life when machining steel and cast iron.
In a recent example in North America, an end user was face milling gas turbine end caps made of stainless steel on a large horizontal mill. An Econ LN 80 mm face mill with LNGX 12 insert allowed the customer to use a feed rate that was 44% higher than the previous option. The improved cutting data meant that the company ran the equivalent of three finished parts on the first edge, with the insert showing little-to-no wear. Furthermore, the Econ LN reduced cycle time by 18 minutes in this operation alone.
