Kev lag luam automotive xav tau cov khoom siv uas ua tau raws li cov qauv ntawm cov precision, durability, thiab kev ua tau zoo. Ntawm qhov tseem ceeb tshaj plaws yog tsav cov kabmob, uas yog qhov tseem ceeb rau kev xa hluav taws xob, kev tswj kev thauj khoom, thiab kev nyab xeeb ntawm lub tsheb. Kev tsim khoom ntawm cov khoom no tau hloov zuj zus mus, nrog rauCNC machining automotive tsav bearing qhov chawtawm los ua tus tseem ceeb thiab txhim khu kev qha ntau lawm txheej txheem. Cov txheej txheem no ua kom paub tseeb qhov tseeb ntawm geometrical, kev ncaj ncees ntawm cov khoom, thiab qhov zoo ib yam uas yuav tsum tau muaj hauv kev siv tsheb niaj hnub.
Txoj kev tsim khoom pib los ntawm kev xaiv cov khoom tsim nyog, feem ntau siab -carbon chromium steel xws li AISI 52100 lossis lwm cov ntaub ntawv- hardening steels. Cov ntaub ntawv no raug xaiv rau lawv lub zog siab, hnav tsis kam, thiab muaj peev xwm tiv taus ntau qhov sib hloov thiab qaug zog. Cov khoom siv raw, feem ntau nyob rau hauv daim ntawv ntawm bar Tshuag los yog forged blanks, ua ntej txheej txheem xws li tig thiab mos sib tsoo los tsim ib tug nyob ze -net-puab preform. Cov theem no yog qhov tseem ceeb heev rau kev tsim lub hauv paus geometry ua ntej qhov tseem ceeb ntawm kev ua haujlwm nyuaj.
Lub hauv paus ntawm cov txheej txheem tsim khoom yog ntau -axis CNC machining. Niaj hnub nimno CNC tig chaw thiab machining chaw ua haujlwm ntau yam, suav nrog kev xa, drilling, tho txawv, thiab zawj machining. Lub ntsiab lus ntawm cov kabmob no- txoj kev sib tw - yuav tsum tau muaj qhov tshwj xeeb siab. Lub geometry, nto tiav, thiab concentricity ntawm raceways yog machined rau tolerances nyob rau hauv ob peb microns. Piv txwv li, txoj kab uas hla rau cov kabmob rings feem ntau poob hauv qib ISO IT4 txog IT5 qib. Qib no ntawm precision yog unattainable nrog cov pa machining thiab yog ib qho tseem ceeb rau kom ntseeg tau tias du rolling caij ua hauj lwm thiab me me vibration.
Kev sib tsoo yog cov kauj ruam tom ntej thiab tseem ceeb, tshwj xeeb tshaj yog tom qab cov khoom tau dhau los ua kev kho cua sov kom ua tiav qhov tsim nyog ntawm qhov tawv tawv, feem ntau ntawm 58-64 HRC rau cov kabmob rings. CNC sib tsoo tshuab nrog pob zeb diamond lossis CBN lub log yog ua haujlwm kom tiav cov kev sib tw thiab lwm qhov chaw ua haujlwm. Cov txheej txheem no ua tiav qhov tseeb qhov tseeb qhov kawg thiab qhov yuav tsum tau ua tiav super-nplua nto, feem ntau teev nrog tus nqi Ra qis dua 0.2 µm. Ib qho kev tsis zoo nyob rau theem no tuaj yeem ua rau muaj kev tsis txaus ntseeg ntxov ntxov, ua rau cov txheej txheem tseem ceeb.
Kev ruaj ntseg zoo yog kev koom ua ke thoob plaws hauv lub neej ntawm kev tsim khoom. Kev tshuaj xyuas qhov ntev yog ua los ntawm kev siv lub tshuab ntsuas kev sib koom tes (CMM) los txheeb xyuas qhov ua tau raws li CAD qauv thiab kev kos duab kos duab. Qhov kev ncaj ncees ntawm qhov saum npoo yog txheeb xyuas siv cov profileometers. Tsis tas li ntawd, tsis yog-txoj kev kuaj kev puas tsuaj, xws li kev soj ntsuam ultrasonic lossis sib nqus particle, feem ntau ua haujlwm los kuaj xyuas qhov tsis xws luag hauv subsurface lossis micro-kawg uas tuaj yeem cuam tshuam cov khoom ntawm cov qauv kev ntseeg siab hauv kev thauj khoom.
Qhov zoo ntawm kev siv CNC tshuab rau cov khoom no yog manifold. Nws muaj qhov sib piv tsis sib xws, ua kom ntseeg tau tias txhua qhov hauv ib pawg ntau lawm yog qhov zoo ib yam. Qhov no yog qhov tsis yog - qhov yuav tsum tau sib tham tau rau cov kab sib dhos uas siv tau. Tsis tas li ntawd, CNC machining muab qhov yooj yim los tsim cov geometries nyuaj thiab ua kom haum cov qauv kev hloov pauv nrog tsawg kawg nkaus downtime, tsuas yog los ntawm kev hloov kho cov phiaj xwm digital.
Hauv kev xaus, kev hloov mus rau cov txheej txheem CNC qib siab tau hloov pauv qhov chaw tsim khoom rau cov khoom siv tsheb tseem ceeb. Lub peev xwm los tsim cov khoom siv sib xyaw ua ke nrog micron - qib precision, superior nto tiav, thiab cov khoom siv tau lees paub yog qhov tshwm sim ncaj qha ntawm cov thev naus laus zis no. Raws li kev lag luam tsheb txuas ntxiv mus rau kev siv hluav taws xob thiab kev ua haujlwm siab dua, lub luag haujlwm ntawm precision CNC machining yuav tsuas yog qhov tseem ceeb hauv kev xa cov kev ntseeg siab thiab kev ua haujlwm uas lub khw xav tau.
