Funda indlela yokukhetha uluhlu olufanelekileyo lwe-spindle kwaye uqinisekise ukuba lwakhoIziko lomatshini le-CNCokanye iziko lokujika liqhuba umjikelo olungiselelweyo.#cnctechtalk
Nokuba usebenzisa iUmatshini wokungqusha we-CNCngesixhobo sokujikeleza okanye aCNC lathekunye nomsebenzi ojikelezayo ojikelezayo, izixhobo zomatshini ezinkulu ze-CNC zineendlela ezininzi zokuphotha.Uluhlu olusezantsi lwe-spindle lunika amandla amaninzi, ngelixa uluhlu oluphezulu lubonelela ngesantya esiphezulu.Kubalulekile ukuqinisekisa ukuba umatshini ugqityiwe ngaphakathi koluhlu lwesantya esifanelekileyo sokuphotha ukuphumeza eyona mveliso ilungileyo.Nanga amacebiso amahlanu okukhetha uluhlu olufanelekileyo:
Abavelisi besixhobo somatshini bapapasha iimpawu zokusonta kwiincwadi zabo zokusebenza.Apho uya kufumana ubuncinci kunye nobuninzi be-rpm kuluhlu ngalunye, kunye namandla alindelekileyo kulo lonke uluhlu lwe-rpm.
Ukuba awuzange ufunde ezi datha zibalulekileyo, ixesha lakho lomjikelo mhlawumbi alilungiswanga.Ukwenza izinto zibe mbi ngakumbi, unokubeka uxinzelelo olukhulu kwi-spindle motor yomatshini, okanye uyimise.Ukufunda imanyuwali kunye nokuqonda iimpawu ze-spindle kunokukunceda ukuba wenze ngcono imveliso yomatshini wakho.
Kukho ubuncinci iinkqubo ezimbini zokutshintsha uluhlu lokusonta: enye yinkqubo ene-multi-winding spindle drive motor, kwaye enye yinkqubo ene-mechanical drive.
Eyangaphambili itshintsha uluhlu nge-elektroniki ngokutshintsha i-motor windings abayisebenzisayo.Olu tshintsho luphantse lwenzeke ngoko nangoko.
Inkqubo enothungelwano ngoomatshini idla ngokuqhuba ngokuthe ngqo kuluhlu lwayo oluphezulu kwaye ibandakanya uthumelo kuluhlu olusezantsi.Utshintsho loluhlu lungathatha imizuzwana embalwa, ngakumbi xa i-spindle kufuneka ime ngexesha lenkqubo.
Kwi-CNC, utshintsho loluhlu lokuphotha lubonakala elubala, kuba isantya sokusonta sichazwe kwi-rpm, kwaye igama le-S lesantya esichaziweyo liya kwenza ukuba umatshini ukhethe uluhlu olufanelekileyo lokuphotha.Cinga ukuba uluhlu oluphantsi lwesantya somatshini luyi-20-1,500 rpm, kwaye uluhlu olukhawulezayo luyi-1,501-4,000 rpm.Ukuba ukhankanya igama le-S le-S300, umatshini uya kukhetha uluhlu oluphantsi.Igama le-S le-S2000 liya kwenza umatshini ukhethe uluhlu oluphezulu.
Okokuqala, inkqubo inokubangela utshintsho olungeyomfuneko kumda phakathi kwezixhobo.Ukuhanjiswa koomatshini, oku kuya kwandisa ixesha lomjikelo, kodwa kunokungahoywa kuba kubonakala kuphela xa ezinye izixhobo zithatha ixesha elide ukutshintsha kunezinye.Izixhobo zokuqhuba ezifuna uluhlu olufanayo ngokulandelelana ziya kunciphisa ixesha lokujikeleza.
Okwesibini, ukubalwa kwesantya se-spindle rpm kwimisebenzi erhabaxa enamandla inokubeka i-spindle kwisiphelo esisezantsi soluhlu oluphezulu lokuphotha, apho amandla anqongopheleyo.Oku kuya kwenza uxinzelelo olugqithileyo kwinkqubo yokuphotha okanye kubangele ukuba i-spindle motor ime.Umdwelisi onolwazi uya kunciphisa kancinci isantya se-spindle kwaye akhethe esona santya siphezulu kuluhlu oluphantsi, apho kukho amandla aneleyo okwenza umsebenzi womatshini.
Kwiziko lokuguqula, ukutshintshwa koluhlu lwe-spindle lwenziwa ngekhowudi ye-M, kwaye uluhlu oluphezulu luvame ukugqithwa kunye noluhlu oluphantsi.Kwiziko lokujika elinoluhlu lwe-spindle ezintathu, i-gear ephantsi inokuhambelana ne-M41 kwaye isantya si-30-1,400 rpm, i-gear ephakathi inokuhambelana ne-M42, kwaye isantya si-40-2,800 rpm, kwaye isantya esiphezulu sinokuhambelana. ukuya M43 kunye nesantya 45-4,500 rpm.
Oku kusebenza kuphela kumaziko okuguqula kunye nemisebenzi esebenzisa isantya esiphezulu somphezulu.Xa isantya esiphezulu sihlala sihlala, i-CNC iya kukhetha ngokuqhubekayo isantya (rpm) ngokwesantya esichaziweyo somphezulu (iinyawo okanye m/min) kunye nobubanzi obucutshungulwayo ngoku.
Xa useta i-feedrate per revolution, isantya sokusonta sithelekisana nexesha.Ukuba unokuphinda kabini isantya sokusonta, ixesha elifunekayo kwimisebenzi yomatshini enxulumeneyo liya kunqunyulwa libe lisiqingatha.
Umgaqo odumileyo wokukhetha uluhlu lwe-spindle kukurhabaxa kuluhlu oluphantsi kunye nokugqiba kuluhlu oluphezulu.Nangona oku kungumgaqo olungileyo wokuqinisekisa ukuba i-spindle inamandla awoneleyo, ayisebenzi kakuhle xa kuqwalaselwa isantya.
Qwalasela i-intshi e-1 yedayamitha yokusebenzela ekufuneka ijikwe rhabaxa kwaye ijikwe kakuhle.Isantya esicetyiswayo sesixhobo sokurhabaxa yi-500 sfm.Nangona kubukhulu obukhulu (i-intshi eyi-1), iya kuvelisa i-1,910 rpm (i-3.82 amaxesha angama-500 ahlulwe ngu-1).Idayamitha encinci iya kufuna isantya esiphezulu.Ukuba umdwelisi ukhetha uluhlu oluphantsi ngokusekelwe kumava, i-spindle iya kufikelela kumda we-1,400 rpm.Ukuthatha amandla aneleyo, ukusebenza ngokurhabaxa kuya kugqitywa ngokukhawuleza kuluhlu oluphezulu.
Oku kusebenza kuphela kumaziko ajikayo kunye nemisebenzi erhabaxa efuna isantya esingaguqukiyo somphezulu.Cinga ngokujika ngokurhabaxa kweshafti ye-intshi e-4 yedayamitha enedayamitha ezininzi, eyona incinci ibe yi-intshi enye.Cinga ukuba isantya esicetyiswayo yi-800 sfm.Kwi-intshi ezi-4, isantya esifunekayo yi-764 rpm.Uluhlu oluphantsi luya kunika amandla afunekayo.
Njengoko i-roughing iqhubeka, ububanzi buba buncinci kwaye isantya sanda.Kwi-intshi ye-2.125, i-machining efanelekileyo idinga ukudlula i-1,400 rpm, kodwa i-spindle iya kuphakama kwinqanaba eliphantsi le-1,400 rpm, kwaye inkqubo nganye eqhubekayo yokugoba iya kuthatha ixesha elide kunokuba lifanele.Kuya kuba bubulumko ukutshintshela kuluhlu oluphakathi ngeli xesha, ngakumbi ukuba uluhlu lutshintsha ngoko nangoko.
Xa inkqubo ingena kumatshini, naliphi na ixesha eligcinwe ngokutsiba ulungiselelo lwenkqubo lunokulahleka ngokulula.Nceda ulandele la manyathelo angezantsi ukuqinisekisa impumelelo.
Iiparamitha zixelela i-CNC zonke iinkcukacha zesixhobo esithile somatshini esisetyenziswayo kunye nendlela yokusebenzisa zonke iimpawu ze-CNC kunye nemisebenzi.
