New T-style sialon ce­ramic in­serts from Seco ex­cel in un­sta­ble con­di­tions

DEMM Engineering & Manufacturing - - PRODUCT WATCH -

Seco has ex­panded the rough­ing and semi-fin­ish­ing per­for­mance ca­pa­bil­i­ties of its Se­co­max CS100 sialon ce­ramic grade by adding in­serts with T-style edge prepa­ra­tion to the line. Fea­tur­ing a free-cut­ting, ex­tremely sharp ge­om­e­try, the new in­serts bring sta­bil­ity and per­for­mance longevity to the ma­chin­ing of nickel-based su­per­al­loys in un­sta­ble con­di­tions.

Well suited for turn­ing ap­pli­ca­tions that re­quire tight tol­er­ances and low cut­ting forces, the T-style (cham­fered) CS100 in­serts are avail­able in 20-de­gree cham­fers that range from 0.05 mm to 0.1 mm in width. The sharp, neg­a­tive re­in­forced cut­ting edges on th­ese in­serts help ab­sorb some of the high cut­ting force and pres­sure that would oth­er­wise be placed on the ma­chine set­ups and work­pieces.

As a re­sult, th­ese in­serts elim­i­nate the risk of work­piece de­for­ma­tion, es­pe­cially in thin-walled com­po­nents, as well as re­duce ex­ces­sive vi­bra­tions that shorten tool life and neg­a­tively im­pact sur­face fin­ish. The char­ac­ter­is­tics of the T-style in­serts also com­ple­ment the ex­ist­ing S-style (cham­fered and honed) CS100 prod­ucts de­signed to han­dle high cut­ting forces in rigid, sta­ble ma­chin­ing con­di­tions.

Col­lec­tively, the T-style and S-style in­serts in the CS100 line have high abra­sion re­sis­tance and su­pe­rior tough­ness that ex­tends tool life and al­lows for high cut­ting speeds when pro­cess­ing chal­leng­ing ma­te­ri­als such as In­conel, MAR, RENE and Was­paloy. In other words, man­u­fac­tur­ers, es­pe­cially those in aero­space and power gen­er­a­tion, us­ing th­ese in­serts ben­e­fit from high pro­duc­tiv­ity, con­sis­tent qual­ity and a low cost per part.

Fur­ther­more, Seco has added new ce­ramic insert hold­ers to its com­pre­hen­sive prod­uct port­fo­lio. Avail­able in stan­dard shaft and Seco-Capto styles, th­ese hold­ers have spe­cial pocket de­signs and clamp­ing sys­tems that eas­ily ac­com­mo­date the dif­fer­ent thick­nesses and miss­ing cen­tremount­ing holes that are com­mon with th­ese types of in­serts.
