2 2 Had tunng Inceasngly, components made fom hadened steel such as those used n the gea, dve o beang ndustes ae beng machned usng had tunng wth moden cuttng mateals and tools. Accodngly, the hgh standads beng set n suface qualty and dmensonal and shape accuacy must be acheved wth pocess elablty. Components n mass o batch poducton must be manufactued wth the hghest possble effcency. In ths context, had tunng s the poducton pocess that facltates a dastc educton n pocessng tmes, whch leads to a sgnfcant decease n machnng costs and a measuable ncease n poductvty. Futhe geneal condtons of poducton, coespondng to end use expectatons, nclude a hgh-pecson delvey at a easonable pce n the desed qualty. A had tunng pocess that s techncally optmsed fo maxmum effcency s theefoe essental: The goal s to ncopoate not only the appopate hgh-pefomance tool systems, but also hgh-end machnng technology, know-how and fne-tuned tool logstcs nto the had tunng pocedue. Wth ts extensve poduct and sevce potfolo, SPK Cuttng Tools known as SPK+ The Poductvty Expets s sng to ths challenge. The had tunng pocess s taloed accodng to custome equements and s pefected n ts entety fom the cuttng edges and technology used up to machne applcaton and tool logstcs. SPK had tunng solutons fo: Sgnfcantly educed machnng tmes Inceased pocess elablty Hgh pocess flexblty Excellent suface qualtes Contnuous and nteupted cuts Chp beakes fo had/ soft tanstons Hgh dmensonal and shape accuacy SPK-HD-LINE next geneaton mateals fo hgh-speed had tunng and geate machnng feedom thanks to: - Up to 200% moe tool lfe - Cuttng speed up to 240 m/mn - Wth a feed ate up to 0.5 mm

3 3 SPK HD-Lne The band new cuttng mateal and laye system HD-LINE has been especally developed fo hgh-pefomance had tunng opeatons. All HD-LINE gades have an exceptonally hgh edge stablty and mnmal cate wea. Fo the ente applcaton spectum fom contnuous to lghtly and heavly nteupted cuts the hgh-pefomance specalsts ae well pepaed wth the ange of new gades, whch means that uses can desgn the optmal had tunng pocess fo the espectve applcaton usng the cuttng mateals of the HD-LINE. Both mult-tpped and Sold ndexable nsets ae theefoe avalable fo had tunng opeatons wth the. gades Gades Sold Mult-tpped WXM 155 WXM 255 WXM 355 WXM 455 WXM 155 The cycle tme po Ths new type of cuttng mateal s settng new standads when t comes to effcency. Hgh themal stablty and ed hadness make t extemely wea esstant. Mateals wth a hadness of up to 62 HRC can be easly machned wth speeds up to v c = 180 m/mn n contnuous cut. The Sold vesons suppot the flexble desgn of the had tunng pocesses. Adjustng the pocess desgn n ths way can educe machnng tmes by 50% and sometmes moe, when compaed to mult-tpped PCBN. WXM 255 The dmensonal accuacy expet The extaodnay wea esstance of ths cuttng mateal s settng new standads fo shape and dmensonal accuacy. Thanks to ts themally hghly-stable bnde and low chemcal affnty to chome, ths gade s patculaly sutable fo machnng hadened beang steels. Extemely hgh tool lves can be acheved elably n contnuous cut. The outstandng cate wea esstance educes the sk of cuttng edge beakage and nceases the pocess elablty. WXM 355 The all-ounde Regadless of the opeaton, WXM355 s the ght choce. The balance of toughness and wea esstance make ths gade deal fo case-hadened steel; the tool lfe wndow s also extended by up to 50%. The Sold veson allows fo elable petunng as well as dawn cuts. WXM 455 Specalst fo nteupted cuts The WXM 455 s the top choce fo machnng wth the most heavly nteupted cuts. Fo these applcatons, the cuttng mateal s toughness and esstance to abason s hugely mpotant. Ths gade offes a hgh degee of toughness and, thanks to ts optmsed wea esstance, t can be mplemented fo machnng wth cuttng speeds up to v c = 220 m/mn wth heavly nteupted cuts.

8 8 KS-PoMn the tool SySteM Fo Had tunng Thanks to ou boad spectum of clampng systems, we can povde the deal tool fo any had tunng applcaton. In ode to meet the extemely hgh demands on postonal and shape toleances as well as suface qualty, we have developed clampng systems whch, n combnaton wth ou cuttng mateals, can elably meet these stct toleance equements. KS-PoMn KS-PoMn The newly developed IKS-Pomn clampng system s based on IKS-Po. The poven notch geomety used n IKS-Po has been futhe developed n ode to meet the equements of had tunng wth Sold nsets. The fom-ft and foce-ft connecton ensues the etacton of the nset nto the nset seatng and guaantees an extemely stable and secue clamp fo had tunng. The cuttng foces appled on the nset and the clampng system dung had fne machnng ae theeby optmally dstbuted acoss the ente nset seatng and base. Ths makes the IKS-Pomn the optmum clampng system fo achevng the most naow toleances usng both contnuous and lghtly to heavly nteupted cuts; wth absolute pocess elablty. moeove, thanks to ts pactcal, smple and fast opeaton, IKS-Pomn allows uses to meet the hghest qualty equements quckly, safely and easly on a daly bass. As a esult, IKS-Pomn can sgnfcantly ncease poductvty though ts gd clampng chaactestcs, optmal cuttng foce dstbuton and smple use, whle openng up futhe cost educton possbltes fo had tunng opeatons.

9 9 Specal solutons Customsed solutons The dffeng sze and complexty of hadened components often demand sophstcated machnng solutons that use specal tools. Ou engneeng team asssts customes wth the cedo of usng as many standad tools as possble and as many specal tools as equed. Tool solutons ae conceved fo achevng optmum machnng esults and the hghest level of effcency. Sold and mult-tpped vesons ae avalable fo mplementng customsed nsets. As a manufactung company, we poduce specal nset geometes and tools n ou poducton faclty n Gemany. Ths gves ou customes the advantage that we can supply even the most complex geometes wthn a shot peod of tme. If adjustments need to be made on exstng tools, these can also be pefomed quckly and flexbly.

The use of cuttng nsets wth a ZZ geomety allows fo sgnfcantly hghe suface qualtes to be acheved n compason wth nsets featung standad geometes. Altenatvely, the man machnng tmes can be educed consdeably wthout any consequences to hgh suface qualtes. Theefoe, the ZZ geometes epesent one of the most effcent ways of nceasng poductvty n machnng, especally n fnshng opeatons.
