Substitution of grinding processes in crankshaft machining \u2013 NILES-SIMMONS Industrieanlagen GmbH introduces new technology hard milling<\/strong><\/h1>\n

Dipl.-Ing. Michael Kamm, Dipl.-Ing. Eric Rein\u00adwarth, NILES-SIMMONS Indus\u00adtrie\u00adan\u00adla\u00adgen GmbH<\/em><\/p>\n

In today\u2019s mar\u00adket place, the most important dri\u00adving forces in the field of auto\u00admo\u00adtive indus\u00adtry are sus\u00adtaina\u00adbi\u00adlity, resource con\u00adser\u00adva\u00adtion and eco\u00adno\u00admic effi\u00adci\u00adency. These trends do not only drive the deve\u00adlo\u00adp\u00adment of new inno\u00adva\u00adtive tech\u00adno\u00adlo\u00adgies and final con\u00adfi\u00adgu\u00adra\u00adti\u00adons for new pro\u00adducts, but also push the ever-incre\u00adasing requi\u00adre\u00adments of the manu\u00adfac\u00adtu\u00adr\u00aders to find new cost-effi\u00adci\u00adent manu\u00adfac\u00adtu\u00adring con\u00adcepts for the pro\u00adduc\u00adtion of the exis\u00adting com\u00adpon\u00adents in production.<\/p>\n

In order to meet these mar\u00adket requi\u00adre\u00adments, NILES-SIMMONS have deve\u00adlo\u00adped the new tech\u00adno\u00adlogy \u201chard mil\u00adling\u201d for the machi\u00adning of har\u00addened cranks\u00adhafts for truck\u2011, con\u00ads\u00adtruc\u00adtion machi\u00adnery- and agri\u00adcul\u00adtu\u00adral machi\u00adnery engines.<\/p>\n

This tech\u00adno\u00adlogy allows for the sub\u00adsti\u00adtu\u00adtion of a grin\u00adding pro\u00adcess for machi\u00adning of large cranks\u00adhafts by the imple\u00admen\u00adta\u00adtion of an effi\u00adci\u00adent mil\u00adling pro\u00adcess. In turn, the enorm\u00adous pre- grin\u00adding efforts, which had been requi\u00adred for machi\u00adning of cranks\u00adhafts after har\u00addening is remo\u00adved and the pre\u00adpa\u00adra\u00adtion for the finish grin\u00adding pro\u00adcess is per\u00adfectly con\u00adtrol\u00adled to reduce finis\u00adhing requi\u00adre\u00adments to a minimum.<\/p>\n

The pro\u00adcess is spe\u00adci\u00adfi\u00adcally adapted for the machi\u00adning of 4, 5, 6 and 8 cylin\u00adder-cranks\u00adhafts with a maxi\u00admum length of up to 1350mm and a maxi\u00admum fly\u00ading cir\u00adcle of up to 310mm. It is available on both NILES-SIMMONS mil\u00adling cen\u00adters N20CM und N30CM.<\/p>\n

These spe\u00adcial pur\u00adpose machi\u00adnes, which belong to the NILES-SIMMONS crank mil\u00adling (CM)- series, are inher\u00adently equip\u00adped with a distance bet\u00adween cen\u00adters of up to 2000mm tog\u00ade\u00adther with a maxi\u00admum dia\u00adme\u00adter of up to 780mm and carry out highly relia\u00adble dry-mil\u00adling machi\u00adning pro\u00adces\u00adses with extra\u00ador\u00addi\u00adnary long-life pre\u00adcis\u00adion at extre\u00admely high-pro\u00adduc\u00adtion levels. Thanks to their fle\u00adxi\u00adble auto\u00adma\u00adtion opti\u00adons, the machi\u00adnes run with mini\u00admal ope\u00adra\u00adtor inter\u00adven\u00adti\u00adons. The most favored loa\u00adding con\u00adcepts are for ins\u00adtance the work\u00adpiece loa\u00adding by over\u00adhead gan\u00adtry via an inte\u00adgra\u00adted hatch\u00adway or work\u00adpiece loa\u00adding by robot via the machine\u2019s front doors.<\/p>\n

For the imple\u00admen\u00adta\u00adtion of the spe\u00adci\u00adfic pro\u00adcess \u201chard mil\u00adling\u201d for large cranks\u00adhafts as a clo\u00adsed pro\u00adcess, the machi\u00adnes are equip\u00adped with main- and coun\u00adter spind\u00adles with a maxi\u00admum tur\u00adning moment of 930Nm (100%) each as well as two mil\u00adling units with maxi\u00admum tur\u00adning moment of 3350Nm (S1-100%) each.<\/p>\n

The mil\u00adling tools used are sup\u00adplied by the com\u00adpany \u2018Inger\u00adsoll Werk\u00adzeuge GmbH, with tool dia\u00adme\u00adters of 700 \u2013 800mm and a cut\u00adting width up to 95mm they are equip\u00adped with spe\u00adci\u00adfi\u00adcally deve\u00adlo\u00adped cera\u00admic cut\u00adting inserts. By using these, the mil\u00adling pro\u00adcess of the main- and pin bea\u00adrings runs with a radial cut\u00adting depth of up to 0,5mm at hard\u00adness of up to 59 HRC. The cut\u00adting speeds applied are bet\u00adween 250 and 275m\/min and the feed rates are set bet\u00adween 0,23 \u2013 0,35mm. The tool con\u00ads\u00adtruc\u00adtion is pos\u00adsi\u00adble both in mono\u00adbloc-design and  in cartridge-design.<\/p>\n

 <\/p>\n

For clam\u00adping of the work\u00adpie\u00adces, we use com\u00adpen\u00adsa\u00adting mil\u00adling jaw chucks in main and coun\u00adter spindle. Those spe\u00adci\u00adfic, power-ope\u00adra\u00adted lever chucks with a dia\u00adme\u00adter of 320mm, have a sen\u00adsi\u00adtive adjus\u00adt\u00adment of less or equal 20\u00b5m on the clam\u00adping dia\u00adme\u00adter and con\u00adse\u00adquently allow a highly effi\u00adci\u00adent com\u00adpen\u00adsa\u00adtion of dis\u00adtor\u00adtion due to the har\u00addening.  For addi\u00adtio\u00adnal back\u00ading, we use two self-cen\u00adte\u00adring mil\u00adling ste\u00adady rests with pin loca\u00adtor jaws.<\/p>\n

On top of that, the machine has an inte\u00adgra\u00adted touch probe for exact and pro\u00adcess relia\u00adble iden\u00adti\u00adfi\u00adca\u00adtion of the work\u00adpiece position.<\/p>\n

With that, dia\u00adme\u00adter-accu\u00adra\u00adcies of 25\u00b5m, round\u00adness-accu\u00adra\u00adcies of 10\u00b5m and posi\u00adtion-accu\u00adra\u00adcies of the pin bea\u00adrings of 0,1mm are accom\u00adplished. As a result, the finish- grin\u00adding pro\u00adcess is per\u00adfectly prepared.<\/p>\n

 <\/p>\n

Pro\u00adgramming of the pro\u00adcess takes place by use of the spe\u00adci\u00adfi\u00adcally deve\u00adlo\u00adped crank mil\u00adling soft\u00adware of NILES-SIMMONS. This soft\u00adware allows for com\u00adple\u00adtely inde\u00adpen\u00addent pro\u00adgramming for machi\u00adning of main- and pin bea\u00adrings, cen\u00adtric ele\u00adments, cheeks and spe\u00adci\u00adfic cheek con\u00adtours. The ope\u00adra\u00adtor can easily imple\u00adment neces\u00adsary cor\u00adrec\u00adtions by use of cor\u00adre\u00adspon\u00adding input fields and is extre\u00admely ope\u00adra\u00adtor fri\u00adendly. The ope\u00adra\u00adtor can also import form cor\u00adrec\u00adtion tables directly from the mea\u00adsu\u00adring machine and by doing so the pro\u00adgramming is easy and quickly completed.<\/p>\n

The pro\u00adcess runs enti\u00adrely dry, wit\u00adhout any pro\u00adcess fluids and is the\u00adr\u00ade\u00adfore much more sus\u00adtainable than grin\u00adding pro\u00adces\u00adses, which had to be used up until now. Con\u00adse\u00adquently, the main\u00adten\u00adance requi\u00adre\u00adments and manu\u00adfac\u00adtu\u00adring run\u00adning costs decrease significantly.<\/p>\n

With the use of the new hard mil\u00adling tech\u00adno\u00adlogy, the finish grin\u00adding requi\u00adre\u00adments for machi\u00adning of large cranks\u00adhafts can typi\u00adcally decrease by up to 75 per\u00adcent. The invest\u00adment costs for the num\u00adber of machi\u00adnes decrea\u00adses remar\u00adkably by up to 50 per\u00adcent. Inte\u00adgra\u00adtion and adapt\u00ada\u00adtion of the machi\u00adning pro\u00adcess into exis\u00adting manu\u00adfac\u00adtu\u00adring lines is easily pos\u00adsi\u00adble. Hard mil\u00adling alre\u00adady runs suc\u00adcessfully within cranks\u00adhaft pro\u00adduc\u00adtion lines in the mar\u00adket and achie\u00adves pro\u00adcess-relia\u00adble cycle times of six minutes.<\/p>\n
