Ukuguqula ukusetyenziswa okusisigxina kunokuba kujikelezwe izixhobo kuba ukujika kujikeleza i-workpiece, kungekhona isixhobo.Izixhobo zokuguqula zihlala zibandakanya ukufakwa okutshintshekayo kumzimba wesixhobo sokuguqula.Iiblades zizodwa ngeendlela ezininzi, kubandakanya imilo, izinto eziphathekayo, ukugqiba kunye nejometri.Imilo inokuba ngqukuva ukunyusa ukomelela komphetho, okwedayimani ukuze inqaku livumele ukusika iinkcukacha ezintle, okanye isikwere okanye i-octagonal ukwandisa inani leencam zomntu ngamnye ezinokusetyenziswa njengokuphela komphetho omnye emva komnye.Izinto eziphathekayo zidla ngokuba yi-carbide, kodwa kwizicelo ezifunwa kakhulu nge-ceramic, i-cermet okanye i-diamond efakelwayo ingasetyenziswa.Iingubo ezahlukeneyo zokukhusela zikwanceda ezi zixhobo ze-blade zisike ngokukhawuleza kwaye zihlala ixesha elide.
Olu tshintsho lulula kwindlela yesixhobo kwi-lathe yesi-Swiss-style inokuphucula kakhulu isakhono sayo sokulawula itshiphu.
Ukujika kusebenzisa i-lathe ukususa izinto ngaphandle kwendawo yokusebenza ejikelezayo, ngelixa i-boring isusa izinto ngaphakathi kwendawo yokusebenza ejikelezayo.
Ukunikezelwa kweemfuno ezikhulayo zokugqitywa, ifomula entsha ye-cubic boron nitride inokuba yinto ethembekileyo ngakumbi kwi-carbide enesamente.
Ezi mpawu zinceda ukuphucula ukuzinza kwesixhobo sokusika, ukulungelelanisa ukusebenza kokusika, kunye nokwandisa ubomi besixhobo, ukuvumela iindibano zocweyo ukuba zisebenze zingajongwanga ngokuzithemba.
Abaphandi be-UNCC bazisa ukumodareyitha kwiindlela zesixhobo.Injongo yayiyi-chip breaking, kodwa izinga eliphezulu lokususa isinyithi laliyimpembelelo enomdla.
Ii-chipbreakers ezahlukeneyo zenzelwe iiparamitha ezahlukeneyo.Ukucutshungulwa kwevidiyo ebonisa umahluko ekusebenzeni kakuhle phakathi kwee-chipbreakers ezisetyenziswa kwizicelo ezilungileyo nezingalunganga.
Ukuguqula yinkqubo yokususa izinto kwi-diameter yangaphandle ye-workpiece ejikelezayo usebenzisa i-lathe.Abasiki benqaku elinye basika isinyithi ukusuka kwisixhobo sokusebenza sibe (ngokufanelekileyo) iitshiphusi ezimfutshane, ezibukhali ekulula ukuzisusa.
Izixhobo zokujika zakwangoko yayiziziqwenga eziluqilima eziluxande ezenziwe ngesantya esiphezulu sentsimbi enerakhi kunye neekona zokucoca kwelinye icala.Xa isixhobo sisiba buthuntu, umkhandi wesitshixo usilola kwisixhobo sokusila ukuze sisetyenziswe ngokuphindaphindiweyo.Izixhobo ze-HSS zisaxhaphakile kwiileyile ezindala, kodwa izixhobo ze-carbide ziye zaziwa ngakumbi, ngakumbi kwifom ye-brazed single point.I-Carbide inokumelana nokunxiba okungcono kunye nobunzima, okwandisa imveliso kunye nobomi besixhobo, kodwa kubiza kakhulu kwaye kufuna amava ukubuyisela kwakhona.
Ukujika kukudibanisa umgca (isixhobo) kunye ne-rotary (workpiece) intshukumo.Ngoko ke, isantya sokusika sichazwa njengomgama wokujikeleza (obhalwe njenge-sfm - i-surface foot ngomzuzu - okanye i-smm - i-square meter ngomzuzu-ukuhamba kwephuzu phezu kwenxalenye ngomzuzu omnye).I-feedrate (echazwe ngee-intshi okanye i-millimeters nge-revolution) ngumgama womgca ohambayo isixhobo okanye ukuwela umphezulu we-workpiece.Ukutya kwakhona ngamanye amaxesha kuchazwa njengomgama omgca (in/min okanye mm/min) esiwuhambayo isixhobo ngomzuzu omnye.
Iimfuno zesantya sokutya ziyahluka ngokuxhomekeke kwinjongo yokusebenza.Umzekelo, kwi-roughing, ukutya okuphezulu kudla ngokuba ngcono ekwandiseni amaxabiso okususwa kwesinyithi, kodwa inxalenye ephezulu yokuqina kunye namandla omatshini ayafuneka.Kwangaxeshanye, ukugqiba ukujika kunokucothisa isantya sokutya ukuze kuphunyezwe uburhabaxa bomphezulu obuchazwe kumzobo wenxalenye.
Ukukruqula kusetyenziswa ikakhulu ukugqiba imingxunya emikhulu emingxumayo kwi-castings okanye imingxuma yokugqobhoza kwi-forgings.Uninzi lwezixhobo zifana nezixhobo zemveli zokujika zangaphandle, kodwa i-angle yokusika ibaluleke kakhulu ngenxa yemicimbi yokukhutshwa kwe-chip.
I-spindle kwiziko lokujika inokuba ibhanti liqhutywa okanye liqhutywa ngqo.Ngokubanzi, ii-spindles eziqhutywa ngamabhanti ziteknoloji endala.Ziyakhawuleza kwaye zicuthe kancinci kunezijikelezo ezithe ngqo zokuqhuba, okuthetha ukuba amaxesha omjikelo anokuba made.Ukuba wenza iinxalenye ezincinci zedayamitha, ixesha elifunekayo ukuguqula i-spindle ukusuka kwi-0 ukuya kwi-6000 revolutions lide kakhulu.Enyanisweni, ukufikelela kwesi santya kunokuthatha ixesha eliphindwe kabini njenge-spindle yokuqhuba ngokuthe ngqo.
Izisontena eziqhutywa ngebhanti zinokuba neempazamo ezingephi ngenxa yokushiyeka kwebhanti phakathi kwe-drive kunye ne-encoder.Oku akusebenzi kwi-spindles zokuqhuba ngokuthe ngqo.Ukusetyenziswa kwe-spindle ye-drive ngqo kwisantya esiphezulu sokuphakamisa kunye nokuchaneka kokumisa kuyinzuzo ebalulekileyo xa usebenzisa ukunyakaza kwe-C-axis kumatshini wesixhobo esiqhutywayo.
I-tailstock ye-CNC edibeneyo yinto ebalulekileyo kwiinkqubo ezizenzekelayo.I-tailstock ecwangcisiweyo ngokupheleleyo ibonelela ngokunyuka kokuqina kunye nokuzinza kwe-thermal.Nangona kunjalo, i-tailstock ephosiweyo yongeza ubunzima kumatshini.
Kukho iindidi ezimbini eziphambili zetailstocks ezicwangcisekileyo: i-servo driven kunye ne-hydraulic driven.I-Servo tailstocks ilungile, kodwa ubunzima bayo bunokulinganiselwa.Ngokuqhelekileyo, i-hydraulic tailstocks inentloko ephumayo kunye ne-intshi ezi-6 zokuhamba.I-spindle inokwandiswa ukuxhasa i-workpieces enzima kwaye isebenzise amandla amaninzi kune-servo tailstock.
Izixhobo eziphilileyo zihlala zijongwa njengesisombululo se-niche, kodwa ezininzi iinkqubo ezahlukeneyo zingaphuculwa ngokuphunyezwa kwezixhobo eziphilayo.#isiseko
I-Kennametal KYHK15B ibakala ibikwa ukuba inobunzulu obukhulu bokusikwa kunokufakwa kwe-PcBN kwiintsimbi ezinzima, ii-superalloys kunye nentsimbi.
UWalter unikezela ngamabakala amathathu eTiger tec eGolide aphuhliselwe ngokukodwa intsimbi kunye nokujika kwentsimbi.
Iileyibhile yenye yezona teknoloji zindala zomatshini, kodwa kusekuhle ukugcina iziseko engqondweni xa uthenga i-lathe entsha.#isiseko
Ukufakwa kweWalter cermet ezijikayo zenzelwe ukuchaneka komgangatho, ukugqiba okuphezulu komphezulu kunye nokuncipha kokungcangcazela.
Ngenxa yokuba akukho migangatho yamazwe ngamazwe echaza amabakala e-carbide okanye izicelo, abasebenzisi kufuneka bathembele kwingqiqo kunye nolwazi olusisiseko ukuze baphumelele.#isiseko
Izinto ezintathu ezintsha ze-ISO-P ezifakwe kwi-carbide ezifakwe kwi-CERATIZIT zilungiselelwe iimeko ezithile zokuvelisa.
