Achiev­ing the best of both worlds

DEMM Engineering & Manufacturing - - PRODUCT WATCH -

Ver­sa­til­ity has be­come a ne­ces­sity for mod­ern cut­ting tools, but should this re­quire­ment com­pro­mise a qual­ity end prod­uct? asks Dormer Pramet.

Milling cut­ters, for ex­am­ple, which can sup­port rough­ing to fin­ish­ing ap­pli­ca­tions in all ma­te­ri­als are not un­com­mon in the mar­ket­place, adds the com­pany.

The chal­lenge to­day is to achieve ver­sa­til­ity, while also meet­ing the di­men­sional and fin­ish de­mands that were once only placed on tools de­signed for a spe­cific op­er­a­tion and ma­te­rial type.

Dormer Pramet’s Econ LN is a highly cost- ef­fec­tive, ver­sa­tile milling op­tion, ca­pa­ble of sup­port­ing nu­mer­ous op­er­a­tions in most ma­te­ri­als and still pro­duc­ing an ex­cel­lent sur­face fin­ish, prom­ises the man­u­fac­turer.

The pos­i­tive ax­ial ge­om­e­try on the uni­ver­sal 90° cut­ter al­lows for lower cut­ting forces and smoother ma­chin­ing in steel, cast iron, stain­less steel, non-fer­rous met­als and hard­ened ma­te­ri­als.

With an in­ter­nal cool­ing sys­tem close to the cut­ting edges, a com­bi­na­tion of wiper in­serts, se­cure clamp­ing and re­duced power con­sump­tion, the Econ LN de­liv­ers fast chip- evac­u­a­tion and a con­sis­tently high- qual­ity sur­face fin­ish.

Com­pat­i­ble with the Econ LN are the LNGX 12 and LNMU 16 in­serts with four cut­ting edges. The LNGX 12 in­serts sup­port he­li­cal in­ter­po­la­tion, ramp­ing and pro­gres­sive plung­ing, while the LNMU 16 in­serts are strong and ro­bust for 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 us­ing a large hor­i­zon­tal mill.

The Econ LN 80mm face mill with LNGX 120508ER-MF M6330 insert al­lowed the cus­tomer to use a feed rate that was 44 per­cent than the pre­vi­ous op­tion.

It meant they ran the equiv­a­lent of three fin­ished parts on the first edge, with the insert show­ing lit­tle to no wear. The Econ LN re­duced cy­cle time by 18 min­utes just in this sin­gle op­er­a­tion and achieved five pieces per edge over the orig­i­nal com­peti­tor’s one piece per edge.
