UNIQUE PATENTED WIPER EDGES FOR HIGH-QUAL­ITY SUR­FACE FIN­ISH

DEMM Engineering & Manufacturing - - PRODUCT WATCH -

DORMER PRAMET has re­leased sev­eral new ranges for semi-fin­ish­ing and fin­ish­ing in die and mold ap­pli­ca­tions.

The launch fea­tures an as­sort­ment of CNHX05 dou­ble-sided in­serts, with up to four cut­ting edges. The tool­maker says the unique patented wiper edges gen­er­ate a high- qual­ity sur­face fin­ish, re­sult­ing in re­duced ma­chin­ing time in both shoul­der and face milling ap­pli­ca­tions.

This is sup­ported by a range of SCN05C cut­ters for pro­duc­tive copy milling of steels, hard­ened steels and cast irons. Avail­able in 12mm-20mm di­am­e­ters, the tool’s close pitch in­creases the num­ber of teeth and en­ables at least 20 per­cent higher pro­duc­tiv­ity than stan­dard pitch cut­ters.

It has been de­signed for con­tour­ing, pro­fil­ing, plung­ing and face milling ap­pli­ca­tions. Of­fer­ing de­creased lev­els of vi­bra­tion, the tool has been op­ti­mised for smooth cut­ting of cor­ners and pock­ets.

Dormer Pramet has also launched an insert with six cut­ting edges, the dou­ble- sided WNHX04 insert. This too fea­tures a unique patented wiper edge to gen­er­ate su­pe­rior fin­ish on com­po­nent walls and face, re­duc­ing time in cut.

This lat­est insert is com­pat­i­ble with a new range of eco­nom­i­cal and pro­duc­tive copy milling tools. The SWN04C cut­ter, avail­able in di­am­e­ters be­tween 20-35mm, of­fers a va­ri­ety of dif­fer­en­tial pitch op­tions to en­hance sur­face fin­ish and sup­port the six- cut­ting edge insert.

De­signed for smooth cut­ting in op­er­a­tions with long over­hang, it can be used in con­tour­ing, pro­fil­ing, plung­ing and face milling ap­pli­ca­tions with a depth of cut up to 2mm.

As with the SCN05C cut­ter, the SWN04C range is suit­able for semifin­ish­ing and fin­ish­ing ap­pli­ca­tions in steels, hard­ened steels and cast irons for the mold and die seg­ment.

In a re­cent ex­am­ple, the WNHX insert with WM ge­om­e­try and new M4310 grade was used to ma­chine tool steel at 0.50mm depth of cut. With a cut­ting speed of 196m/min and feed rate of 3,600mm/min, the tool re­duced ma­chin­ing time by 45 per­cent, com­pared to a com­peti­tor’s equiv­a­lent.
