The HSTM-LC is an offer of a ful­ly auto­ma­ted machi­ning cen­ter to manu­fac­tu­r­ers of tur­bi­ne and com­pres­sor blades that fea­tures com­pre­hen­si­ve mea­su­ring tech­no­lo­gy and a laser clad­ding unit to pro­vi­de them with decisi­ve tech­no­lo­gi­cal advan­ta­ges when machi­ning com­pon­ents made of high-tem­pe­ra­tu­re nickel-based alloys or titanium. Model variants The HSTM exceeds the hig­hest requi­re­ments of modern bla­de machi­ning in terms of achie­va­ble accu­ra­ci­es and sur­face qualities. 3D laser clad­ding is essen­ti­al­ly a 3D prin­ting tech­ni­que based on wel­ding, in which metal is mel­ted with a laser and clad onto a part. This is pos­si­ble with vir­tual­ly all con­ven­tio­nal weld metals. In addi­ti­on, the con­cen­tra­ted heat input and low mate­ri­al impact allow dif­fi­cult-to-weld mate­ri­als to be deposited. Appli­ca­ti­on in a turning/milling machi­ne crea­tes a new pri­ce advan­ta­ge for the­se sys­tems and also has the advan­ta­ge that the appli­ed metal can be sur­face finis­hed by milling/polishing in a sin­gle clamping. Advantages of buildup welding In addi­ti­on to recon­di­tio­ning worn or dama­ged are­as of a com­po­nent, laser clad­ding can com­bi­ne dif­fe­rent mate­ri­als to impro­ve com­po­nent pro­per­ties. Laser clad­ding, for exam­p­le, per­mits the effec­ti­ve com­bi­na­ti­on of dif­fe­rent mate­ri­als. This allows a part made of a sub­stra­te mate­ri­al with good struc­tu­ral pro­per­ties (sel­ec­ted for its strength, tough­ness and resis­tance) to be sur­face coa­ted with a har­der and more inert mate­ri­al to increase its wear and cor­ro­si­on resis­tance.
