Kwiphulo elingapheliyo lokuphucula imveliso, ukuzinza kwesiseko somatshini we-CNC kubaluleke kakhulu. Njengoko isantya se-spindle sinyuka sidlula i-30,000 RPM kwaye ukunyamezelana kuncipha ukuya kwinqanaba le-sub-micron, izinto zokwakha zebhedi yomatshini—ezidla ngokubizwa ngokuba “yisiseko”—ziba yinto ethatha isigqibo phakathi kokugqitywa komphezulu osemgangathweni ophezulu kunye nenxalenye elahliweyo. Kangangamashumi eminyaka, eli shishini belixoxa ngezibonelelo zezinto ezahlukeneyo zesiseko, apho isinyithi sendabuko sihlala silahlekelwa ngumhlaba ngenxa yeendlela ezimbini ezibalaseleyo: i-Natural Granite kunye ne-Mineral Casting (ekwaziwa ngokuba yi-polymer concrete okanye i-artificial granite).
Nangona zombini ezi zinto zibonelela ngeenzuzo ezibalulekileyo kunesinyithi, ukukhetha phakathi kwazo kufuna ukuqonda okunzulu ngeempawu zazo zomzimba, ngakumbi malunga nokuxinana kokungcangcazela. Eli nqaku libonelela ngohlalutyo lobuchwephesha lwendlela iMineral Casting kunye neNatural Granite ezahlukileyo ngayo kubuchule bazo bokufunxa amandla, ukumelana nokuguquguquka kobushushu, kunye nokugcina uzinzo lwejiyometri kwiindawo zoomatshini ezikhawulezayo.
Ifiziksi yokungcangcazela: Kutheni kubalulekile ukuba ukudambisa kube yinto ebalulekileyo
Ukuze siqonde uthelekiso, kufuneka siqale sichaze ingxaki. Kwi-CNC machining, ukungcangcazela lutshaba lokuchaneka. Ukungcangcazela kuveliswa kukushukuma ngokukhawuleza kwee-axes, ukujikeleza kwe-spindle, kunye namandla okusika asebenzisana ne-workpiece. Ukuba ezi ngcangcazela azisuswanga, zibangela "ukuxokozela" - ukubonakala kokujika kumphezulu we-workpiece, ukuguguleka kwesixhobo ngokukhawuleza, kunye nomonakalo onokubakho kwizikhokelo zomgca kunye neebheringi zomatshini.
Amandla ezinto zokufunxa la mandla e-kinetic aze awaguqule abe bubushushu obuncinci alinganiswa yi-damping coefficient yayo (okanye i-loss factor). Kulapho i-Mineral Casting kunye ne-Natural Granite zahluka khona kakhulu kwiintsimbi nakwezinye.
I-Granite yendalo: Umgangatho weJiyoloji
I-granite yendalo ibisoloko iyindlela esemgangathweni yegolide ye-metrology echanekileyo kakhulu kunye neziseko zoomatshini, ngakumbi kwi-Coordinate Measuring Machines (CMMs) kunye ne-ultra-precision grinding. Ukuthandwa kwayo kuvela kwimbali yayo yejoloji. Yenziwe kwiminyaka yezigidi phantsi kobushushu obukhulu kunye noxinzelelo, i-granite yinto ezinzileyo ngokwendalo engenaxinzelelo lwangaphakathi.
Amandla okufunxa egranite yendalo ayamangalisa. Inesakhiwo esixineneyo, esikristale esibonelela ngokuqina okuphezulu kunye namandla okufunxa malunga namaxesha ama-5 ukuya kwi-10 kune-grey cast iron. Xa i-vibration wave ifika kwisiseko segranite, isakhiwo sekristale esidibeneyo sinceda ukukhupha amandla ngokukhawuleza.
Ngaphezu koko, igranite ayisebenzi ngokweekhemikhali kwaye ayisebenzisi magnethi. Ayigqwali, kwaye iyamelana nemiphumo yokubola ye-coolants kunye neeoyile. I-thermal expansion coefficient yayo iphantse ibe sisiqingatha sentsimbi, oko kuthetha ukuba ayichaphazeleki lula kutshintsho olubangelwa kukuguquguquka kobushushu. Nangona kunjalo, kuba yinto yendalo, i-anisotropic—iipropati zayo zinokwahluka kancinci ngokuxhomekeke kwicala lengqolowa—nangona “igranite emnyama” ekumgangatho ophezulu (edla ngokuba yi-diabase okanye i-basalt) ikhethwe ngokukodwa ngenxa yokufana kwayo.
Ukuphoswa kweMineral: I-Engineered Composite
Ukubumba iMineral, okubizwa ngokuba yi-polymer concrete okanye i-granite yokwenziwa, imele eyona nto iphambili kwizixhobo zokwakha ezenziwe ngobunjineli. Ngumxube odibeneyo oquka malunga ne-90-95% yee-aggregates zendalo (ezifana ne-quartz, ii-granite chips, okanye i-basalt) ezidityaniswe kunye yi-5-10% ye-polymer resin matrix, ngesiqhelo i-epoxy.
Le nto yenziwe ngokukodwa ukujongana nemida yeentsimbi, kwaye kwezinye iinkalo, ilitye lendalo. Inkqubo yokuvelisa ibandakanya ukugalela umxube kwisikhunta kubushushu begumbi, okuvumela ukudalwa kwezakhiwo ezintsonkothileyo nezingenanto ezineempawu ezidibeneyo ezifana nemijelo yokupholisa kunye nemijelo yekhebula.
Ukusebenza kokudambisa kweMineral Casting luphawu lwayo olucacileyo. Ngenxa yendalo ye-epoxy resin binder ene-viscoelastic, iMineral Casting ibonisa amandla okudambisa aqhele ukuba makhulu ngokuphindwe ka-6 ukuya kwi-10 kune-cast iron kwaye, okubalulekileyo, adla ngokuphindwe ka-2 ukuya ku-4 kune-granite yendalo. I-polymer matrix isebenza njenge-shock absorber kwinqanaba le-microscopic, ngokufanelekileyo "itya" amandla okungcangcazela ngaphambi kokuba asasazeke kwisakhiwo somatshini.
Umboniso Wokuncamathela: Ukuphoswa Kwezimbiwa vs. I-Natural Granite
Xa uthelekisa ezi zimbini ngokuthe ngqo, umahluko ukho kwindlela yokuchithwa kwamandla.
I-Natural Granite ixhomekeke ekungqubaneni kwayo kwangaphakathi phakathi kweekristale zeeminerali. Nangona isebenza kakhulu, iyinto eqinileyo. Kwizicelo zesantya esiphezulu apho amaza e-harmonic anokwakheka ngokukhawuleza, i-granite inika iqonga elizinzileyo kakhulu, kodwa isenokusasaza ezinye iintshukumo eziphezulu ngokuxhomekeke kulwakhiwo oluthile lwelitye.
I-Mineral Casting, ngokuchaseneyo, isebenzisa unxibelelwano oludibeneyo phakathi kwe-hard aggregate kunye ne-resin ethambileyo. Olu lwakhiwo lwenza i-hysteresis loop enkulu ngexesha lokulayisha nokukhupha izinto, nto leyo ethetha ukufunxwa kwamandla okuphezulu. Izifundo kunye nedatha yeshishini zibonisa ukuba umlinganiselo wokudambisa we-Mineral Casting unokusukela kwi-0.02 ukuya kwi-0.045, udlula kakhulu isiphelo esisezantsi se-granite's spectrum. Oku kwenza i-Mineral Casting isebenze ngakumbi kwimisebenzi "ethanda ukuxokozela" efana nokubhola imingxunya enzulu, ukugaywa kwe-titanium ngesantya esiphezulu, okanye ukugqiba iipaseji apho ukurhabaxa komphezulu kubalulekile.
Ngokwendlela esebenzisekayo, umatshini onesiseko seMineral Casting ungazinza ngokukhawuleza emva kokuhamba ngokukhawuleza kunomatshini onesiseko segranite, nto leyo evumela amaxesha omjikelo amafutshane kunye nomthamo ophezulu.
Uzinzo lobushushu kunye noBulungisa beJiyometri
Ngaphaya kokungcangcazela, ukuziphatha kobushushu kukwahlula okubalulekileyo.
I-Natural Granite yaziwa ngokuba ne-thermal inertia yayo. Ine-thermal conductivity ephantsi, nto leyo ethetha ukuba kuthatha ixesha elide ukufudumeza okanye ukupholisa. Olu "luxakeko" luluncedo kwiindawo ezinamaqondo obushushu atshintshatshintshayo, njengoko isiseko somatshini sisebenza njengesinki sobushushu, sigcina i-geometry yaso nokuba ubushushu bomgangatho wevenkile butshintsha. Nangona kunjalo, i-granite kunzima ukuyi-machine. Ukudala umphezulu othe tyaba ngokugqibeleleyo kufuna umsebenzi onobuchule kunye nexesha, kwaye ukufaka izinto (ezifana ne-threaded inserts) kudla ngokufuna ukubhola kunye nokuncamathisela, okunokufaka iindawo ezibuthathaka.
I-Mineral Casting inika uhlobo olwahlukileyo lokuzinza kobushushu. Ngenxa yokuba inyangwa kubushushu begumbi, ayinaxinzelelo lobushushu olushiyekileyo. Ngokungafaniyo nentsimbi ephothiweyo, enokugoba njengoko uxinzelelo lwangaphakathi luyancipha kwiminyaka yokusetyenziswa, i-Mineral Casting igcina imo yayo yejometri ngokungenammiselo. I-coefficient yayo yokwandiswa kobushushu iphantsi kakhulu kwaye inokulungiswa ngexesha lenkqubo yokwenza ukuze ifane neyentsimbi, nto leyo eluncedo xa ufaka izikhokelo zentsimbi ezithe ngqo kwisiseko.
Nangona kunjalo, iMineral Casting ine-thermal conductivity ephantsi kunegranite. Nangona oku kunika uzinzo, kuthetha ukuba ukuba ubushushu buyaveliswangaphakathiisiseko (umz., esivela kwinjini efakwe ngqo kuyo), loo bushushu busenokunganyamalali ngokukhawuleza njengoko bebuya kwenzeka kwi-granite. Ke ngoko, amaqhinga okulawula ubushushu, njengemijelo yokupholisa yangaphakathi (ephoswa lula kwiMineral Casting), adla ngokuba yimfuneko ngakumbi kwiziseko zekhonkrithi zepolymer.
Inkululeko yoYilo kunye neziphumo zoMveliso
Ukukhetha phakathi kwezi zinto kuchaphazela noyilo loomatshini.
I-Natural Granite inqunyelwe bubungakanani beebhloko eziqwengiweyo. Iziseko ezinkulu zoomatshini zihlala zifuna ukudibanisa iziqwenga ezininzi zamatye, nto leyo efaka amalungu anokuchaphazela ukuqina kunye nokufuma. Ngaphezu koko, i-granite iyaphuka; ukungqubana okukhulu okuvela kwisixhobo esiwayo okanye into yokusebenza kunokuqhekeza okanye kuqhekeze isiseko, nto leyo ekhokelela ekulungisweni okubizayo okanye ekutshintshweni.
I-Mineral Casting inika inkululeko yoyilo engenakuthelekiswa nanto. Ingaphoswa kwiimo ezintsonkothileyo, ezi-monolithic ezinobukhulu obahlukeneyo bodonga. Oku kuvumela iinjineli ukuba ziphucule umlinganiselo wokuqina-ubunzima, zenze izakhiwo ezikhaphukhaphu kodwa eziqinileyo kunezinye ze-granite. Ukongeza, izinto ezisebenzayo—ezifana nemisonto yokufakela, imigca ye-pneumatic, kunye nee-linear scale mounts—zinokuphoswa ngqo kwizinto, zinciphise ixesha lokuhlanganisa kwaye zisuse imithombo enokubakho yokungcangcazela okubangelwa ziijoyinti ezibotshiweyo.
Isiphelo: Ukukhetha iSiseko esiLungileyo
Zombini i-Natural Granite kunye ne-Mineral Casting zimele inyathelo elikhulu phambili ukusuka kwisinyithi sendabuko, zibonelela ngozinzo olufunekayo kwimveliso yanamhlanje echanekileyo.
Ukuba isicelo sakho siquka i-metrology echanekileyo kakhulu okanye iindawo apho ukushiyeka kobushushu kuyingxaki ephambili, i-Natural Granite ihlala ilukhetho olukhulu ngenxa yokuhlala kwayo ihleli kwaye irekhodi layo eliqinisekisiweyo kwi-CMMs.
