Added value through main­te­nance

DEMM Engineering & Manufacturing - - MAINTENANCE MATTERS -

Over the last sev­eral years the sub­ject of main­te­nance has clearly gained sig­nif­i­cance. Not sur­pris­ing; af­ter all, com­plex­ity and de­gree of au­to­ma­tion are in­creas­ing con­tin­u­ously with mod­ern pro­cess­ing ma­chines. For­ward-look­ing strate­gies re­duce the risk of mal­func­tion and down times, in­crease the ser­vice life of ma­chines and thereby en­sure con­stant pro­duc­tion qual­ity. The tube bend­ing ma­chine man­u­fac­turer Sch­warze-Ro­bitec of­fers users a com­pre­hen­sive ser­vice – from main­te­nance and in­spec­tion to re­pair and spare parts sup­ply and all the way to mod­erni­sa­tion.

If a high-tech pro­cess­ing ma­chine comes to a stand­still as a re­sult of a mal­func­tion, it quickly gets ex­pen­sive. In par­tic­u­lar, when cus­tomer pro­duc­tion dead­lines can­not be met as a re­sult and if there are con­trac­tual penal­ties. That’s pre­cisely why many com­pa­nies rate main­te­nance no longer as tire­some costs in­stead as a cen­tral fac­tor of suc­cess. The bend­ing spe­cial­ist Sch­warze-Ro­bitec meets this need of in­creased in­vest­ment safety with a com­pre­hen­sive ser­vice con­cept. Af­ter all, the com­pany’s high-qual­ity tube bend­ing ma­chines are de­signed for run times of more than 20 years in con­tin­u­ous op­er­a­tion. So that the ma­chines op­er­ate re­li­ably through­out their whole life­cy­cle, Jürgen Korte, Plant Manager at Sch­warze-Ro­bitec ad­vises con­duct­ing a regular ma­chine check-up which com­prises main­te­nance, in­spec­tion and ser­vice mea­sures. “A tube bend­ing ma­chine should be ser­viced at the lat­est ap­prox­i­mately ev­ery 5,000 work­ing hours,” says Korte. “Oth­er­wise the risk of un­de­sir­able sur­prises will rise ex­po­nen­tially.” Checked are, among other things, the me­chan­i­cal states and pre­cise po­si­tion­ing of guides, bear­ings and spin­dles as well as ca­bles, pumps, valve func­tions, switch­ing de­vices and soft­ware.

If it is a hy­draulic sys­tem, there is also a check for tight­ness and leak­age safety. Pos­si­ble are also soft­ware up­dates, com­pre­hen­sive weak point analy­ses, staff train­ing and other cus­tomer-in­di­vid­ual mea­sures.

“As bend­ing ma­chines are al­ways cus­tom-built, main­te­nance should re­ally be car­ried out by the man­u­fac­turer” em­pha­sizes Korte. “Gen­er­alised providers of industrial ser­vices of­ten do not have pro­found ex­pe­ri­ence in bend­ing tech­nol­ogy nor the nec­es­sary knowl­edge of the user in­dus­tries and their man­u­fac­tur­ing pro­cesses.” Pre­cisely this spe­cialised know-how is in­dis­pens­able – in par­tic­u­lar when the ma­chines have al­ready been in op­er­a­tion for some years and need to be made fit for in­creased or changed de­mands. Sch­warzeRo­bitec of­fers in­te­grated process analy­ses as well as com­plete ma­chine over­hauls and mod­erni­sa­tions, which sub­sti­tute a new pur­chase in many cases. On that sub­ject Plant Manager Korte: “Users should not make false economies, in­stead they should think about the op­ti­mal utilisation of the ser­vice life of their ma­chines and the op­tions for op­ti­mis­ing the sys­tem avail­abil­ity.”
