Products & ServicesThe LYNX2000GRINDERarrives in BRAZILIt gives us gre<strong>at</strong> s<strong>at</strong>isfaction to see a companylike ThyssenKrupp Metalúrgica Campo Limpoamongst <strong>the</strong> customers th<strong>at</strong> have chosen tointroduce a machine tool like <strong>the</strong> Lynx2000 intoits production processes.ThyssenKrupp Metalúrgica Campo Limpo is aThyssenKrupp Technologies company, part of <strong>the</strong>Mechanical Components division, like <strong>Berco</strong>.TKMCL, toge<strong>the</strong>r with <strong>the</strong> ThyssenKruppCrankshasft Co. and ThyssenKrupp Gerlach, is amember of <strong>the</strong> ThyssenKrupp Forging Groupwhich, with its factories in Europe, North andSouth America and Asia, is one of <strong>the</strong> leadingproducers of shafts and engine componentsin <strong>the</strong> world.TKMCL recently installed a double motorised headversion of <strong>the</strong> Lynx2000 grinder in its CampoLimpo factory, <strong>for</strong> final crank pin grinding on amachining line <strong>for</strong> 4 and 6 cylinder heavytransport engine crankshafts.Be<strong>for</strong>e shipment, <strong>the</strong> grinder had to go through apre-acceptance stage in <strong>the</strong> <strong>Berco</strong> factories,which involved <strong>the</strong> grinding of a hundred or socrankshafts with capability testing.Capability testing is a st<strong>at</strong>istical technique <strong>for</strong>analysing <strong>the</strong> capability of a production processto comply with requested design/drawingspecific<strong>at</strong>ions. During <strong>the</strong> subsequent machiningof <strong>the</strong> acceptance b<strong>at</strong>ch shafts, dimensional and<strong>for</strong>m checking was done in our labor<strong>at</strong>ory, withparticular reference to <strong>the</strong> roundness, linearity,cylindricity and angular and radial position of<strong>the</strong> crank pins.This type of analysis is particularly stringent as itrequires high precision machining with stabilityover time.The machine passed <strong>the</strong> test and was shipped. InOctober our engineers, working toge<strong>the</strong>r withTKMCL engineers, completed <strong>the</strong> install<strong>at</strong>ionand started production with <strong>the</strong> grinder.The machine installed, a Lynx2000DW-Crank, is<strong>the</strong> double motorised head version withautom<strong>at</strong>ic workpiece clamping by means offlo<strong>at</strong>ing jaws and is particularly suitable <strong>for</strong>grinding medium ad large size crankshafts.Workpiece drive, in fact, is on both <strong>the</strong> workhead and tailstock side, thus guaranteeinghigh precision control of <strong>the</strong> shaft positionduring machining.The special fe<strong>at</strong>ures of this machine mean th<strong>at</strong><strong>the</strong> workpiece rot<strong>at</strong>ion and <strong>the</strong> position ofwheel in its orbital movement make it possibleto obtain extremely high precision in <strong>the</strong> crankpin roundness.With <strong>the</strong> conviction th<strong>at</strong> this <strong>first</strong> order will be<strong>the</strong> basis <strong>for</strong> fur<strong>the</strong>r collabor<strong>at</strong>ion between <strong>the</strong>two companies in <strong>the</strong> development ofsubsequent production-line crankshaft grindersdesigned to customer specific<strong>at</strong>ions, we wishto thank TKMCL as of now <strong>for</strong> <strong>the</strong> opportunity<strong>the</strong>y have given us.We would also like to take this opportunity tothank Scuderia Ferrari, who installed aLynx2000 in 2004 <strong>for</strong> machining F1 singlese<strong>at</strong>ercrankshafts. The continuousdevelopment of <strong>the</strong> machining process, in fact,allows us to extend our knowledge and fur<strong>the</strong>rrefine grinding technology in a market whereabsolute quality has no limits.Orazio Cappell<strong>at</strong>oDesign Service DivisionBN56 > december 200811
