The Ger­many-based ma­chine tool com­pany Gehring Tech­nolo­gies of­fers hon­ing so­lu­tions for the au­to­mo­tive in­dus­try. With over 90 years of ex­pe­ri­ence, the com­pany man­u­fac­tures ma­chine tools in vary­ing di­men­sions from di­am­e­ter 0.8mm to 1000mm. In au­to­mo­tive in­dus­try, en­gine takes the lion’s share of the hon­ing ap­pli­ca­tions. The sur­face fin­ish­ing is very much tagged with the per­for­mance of the en­gine. Cylin­dri­cal blocks of two-wheel­ers, three-wheel­ers, pas­sen­ger cars, com­mer­cial ve­hi­cles and trucks are the ma­jor driv­ers of per­for­mancere­lated at­tributes. Hon­ing gives the fin­ish­ing touch, the re­quired spec­i­fi­ca­tion and en­sures the per­for­mance of the en­gine. The In­dian au­to­mo­tive in­dus­try is march­ing to­wards the BS IV norms. The car­bon­diox­ide foot print is get­ting mon­i­tored widely and steps are taken to rat­ify the stan­dards. Hon­ing helps in achiev­ing th­ese tar­gets.

Jean Christophe Fin­cato, Man­ag­ing Di­rec­tor of Gehring Tech­nolo­gies In­dia Pvt. Ltd said, “In­dian mar­ket has al­ready tasted the CKD as­sem­bling of our hon­ing machines. We started our op­er­a­tions in In­dia in 2011 and set up a fa­cil­ity in Ben­galuru in 2012 and then on the CKD strat­egy is be­ing fol­lowed. We are as­sem­bling the machines by im­port­ing the base ma­chine from Ger­many. The jigs and fix­tures are man­u­fac­tured here and with the Ger­man base and the process, we in­te­grate the ma­chine in the line. This CKD is well ad­dress­ing the farm equip­ment in­dus­try. We are plan­ning to im­ple­ment the same strat­egy for the pas­sen­ger cars and the mod­ules for the same are in place.”

The com­pany has mar­ket for pas­sen­ger cars in In­dia. But this CKD strat­egy adds value to that. In­dia is no more a mar­ket for which the so­lu­tions are cus­tomised based on the in­vest­ment. But it has started ad­her­ing to the global stan­dards and the same qual­ity machines sets off in the In­dian mar­ket. With this CKD strat­egy crit­i­cal com­po­nents are im­ported from Ger­many lo­cal­is­ing the reg­u­lar tool needs. By do­ing in this way, the cost is strate­gi­cally op­ti­mised. In In­dia, the tech­ni­cal

pa­ram­e­ters and so­lu­tions are coded sim­i­lar to Ger­many, and China-based machines at a lit­tle lower cost with this CKD strat­egy.

The com­pany also stated that the mar­ket it serves is niche. High tech­nol­ogy machines are its strengths and th­ese machines do not have high de­mands. Though the vol­umes are low, the qual­ity can­not be com­pro­mised. As th­ese are the sources of per­for­mance of the en­gine, the sur­face fin­ish­ing and ge­ome­tries should be well ad­hered to the stan­dards of the OEMs and tier sup­pli­ers. The machines are run by electro­mechan­i­cal sys­tems as hy­draulics has be­come ob­so­lete. This adds to its per­for­mance with less cycle time. The ma­chine hardly breaks down and the pro­duc­tion tar­get, qual­ity ev­ery­thing is achieved through a smooth sail.

The machines are com­ing with 2 spin­dles and that de­ter­mines the vol­ume. With 1 spin­dle run­ning, the vol­ume is less and vice versa. Sim­i­larly the machines can be con­nected with the ro­bot for load­ing and un­load­ing. The ma­chine en­sures proper di­am­e­ter and shape. It can be cus­tomised with post gauge so­lu­tions which could val­i­date the mea­sures de­pend­ing on the cus­tomer needs.

The ma­chine tools are stand­alone oc­cu­py­ing less floor space. The de­sign it­self is com­pact and the machines act as a hon­ing cen­tre for them. The ro­bust de­sign aid, tools and hon­ing sticks de­ter­mine the spec­i­fi­ca­tion stan­dards and cus­tomers are ren­dered with the de­sired di­men­sions. Firm hon­ing con­trib­utes cre­ation of spe­cial shape which helps in re­duc­ing the fric­tion and in turn in­creases the per­for­mance. For in­stance, the pis­ton ring in the cylin­der wall may in­duce fric­tional losses and this hon­ing helps in mit­i­gat­ing the same. The process like nano hon­ing re­de­fines the tech­nol­ogy nu­ances in the hon­ing seg­ment and un­leash to­mor­row’s path ahead for hon­ing. In a nut­shell, the tech­nol­ogy evo­lu­tion in hon­ing is com­ple­ment­ing the BS VI norms.

Though cylin­dri­cal blocks in en­gine con­sume the lion’s share in the hon­ing process, gears and pump com­po­nents are also sub­jected to the hon­ing process. “We are endto-end hon­ing so­lu­tion provider for OEMS, Tier-1s and Tier-2s. There are 3 and 4 cylin­der en­gines in the mar­ket. We have to keep in mind the pitch dis­tance while we hone 4 cylin­der en­gines. Only 2 cylin­der is pos­si­ble at a time where the con­cept re­mains the same with 2 cylin­ders and 1 hon­ing sta­tion,” high­lighted Fin­cato.

Com­ment­ing on coolant-less machines, Fin­cato said, coolant­less machines are not pos­si­ble. As the hon­ing machines live through abra­sive process, coolants are es­sen­tial, there­fore wa­ter-based coolants are used. The com­pany’s cur­rent fa­cil­ity in Ben­galuru could be ramped up for in­crease in de­mand. The com­pany has a work force of 20. Re­fur­bish­ing ac­tiv­i­ties are also car­ried out in the fa­cil­ity. “We are plan­ning to do a ma­chine for pas­sen­ger car which could serve 3 and 4 cylin­der en­gines. We are in the process of ex­e­cut­ing CKD strat­egy to strengthen our lo­cal mar­ket. With ev­ery­thing in place, by 2020 we are able to dou­ble our turnover,” Fin­cato said.
