Nokuba usebenzisaUmatshini wokugaya we-CNCngesixhobo esijikelezayo se-spindle okanyeI-CNC latheNgesixhobo sokusebenza esijikelezayo se-spindle, izixhobo zomatshini ezinkulu ze-CNC zineendawo ezininzi ze-spindle. Uluhlu oluphantsi lwe-spindle lubonelela ngamandla angakumbi, ngelixa uluhlu oluphezulu lubonelela ngesantya esiphezulu. Kubalulekile ukuqinisekisa ukuba umatshini wokugaya ugqityiwe ngaphakathi koluhlu oluchanekileyo lwesantya se-spindle ukuze kufezekiswe imveliso engcono. Nazi iingcebiso ezintlanu zokukhetha uluhlu olufanelekileyo:
Abavelisi bezixhobo zomatshini bapapasha iimpawu ze-spindle kwiincwadi zabo zokusebenza. Apho uza kufumana i-rpm encinci kunye neyona iphezulu yoluhlu ngalunye, kunye namandla alindelekileyo kuluhlu lonke lwe-rpm.
Ukuba awukaze ufunde ezi datha zibalulekileyo, ixesha lakho lokujikeleza mhlawumbi alilungiswanga. Okubi kakhulu kukuba, ungabeka uxinzelelo olukhulu kwi-spindle motor yomatshini, okanye uyimise. Ukufunda incwadi yemiyalelo nokuqonda iimpawu ze-spindle kunokukunceda uphucule imveliso yomatshini wakho.
Kukho ubuncinane iinkqubo ezimbini zokutshintsha uhla lwe-spindle: enye yinkqubo ene-multi-winding spindle drive motor, kwaye enye yinkqubo ene-mechanical drive.
Eyokuqala itshintsha uluhlu ngombane ngokutshintsha ii-motor windings abazisebenzisayo. Olu tshintsho luphantse lubekho ngoko nangoko.
Inkqubo enothumelo lwemishini idla ngokuqhuba ngokuthe ngqo kuluhlu lwayo oluphezulu kwaye ibandakanye uthumelo kuluhlu oluphantsi. Utshintsho loluhlu lunokuthatha imizuzwana embalwa, ingakumbi xa i-spindle kufuneka ime ngexesha lenkqubo.
Kwi-CNC, utshintsho loluhlu lwe-spindle lubonakala ngokucacileyo, kuba isantya se-spindle sichazwe kwi-rpm, kwaye igama le-S lesantya esichaziweyo liya kwenza umatshini ukhethe uluhlu lwe-spindle olufanelekileyo. Cinga ukuba uluhlu lwesantya esiphantsi lomatshini yi-20-1,500 rpm, kwaye uluhlu lwesantya esiphezulu yi-1,501-4,000 rpm. Ukuba uchaza igama le-S le-S300, umatshini uya kukhetha uluhlu oluphantsi. Igama le-S le-S2000 liya kwenza umatshini ukhethe uluhlu oluphezulu.
Okokuqala, le nkqubo inokubangela utshintsho olungeyomfuneko kwisithuba esiphakathi kwezixhobo. Kwindlela yokudlulisa umbane, oku kuya kwandisa ixesha lokujikeleza, kodwa kunokungahoywa kuba kubonakala kuphela xa ezinye izixhobo zithatha ixesha elide ukutshintsha kunezinye. Izixhobo ezisebenzisayo ezifuna uluhlu olufanayo ngokulandelelana ziya kunciphisa ixesha lokujikeleza.
Okwesibini, ukubalwa kwesantya se-spindle rpm kwimisebenzi enamandla yokurhawula kunokubeka i-spindle kwisiphelo esisezantsi soluhlu oluphezulu lwe-spindle, apho amandla anqongophele khona. Oku kuya kubeka uxinzelelo olugqithisileyo kwinkqubo ye-spindle drive okanye kubangele ukuba i-spindle motor ime. Umcwangcisi onolwazi uya kunciphisa kancinci isantya se-spindle aze akhethe isantya esiphezulu kuluhlu oluphantsi, apho kukho amandla aneleyo okwenza umsebenzi womatshini.
Kwiziko lokujika, utshintsho loluhlu lwe-spindle lwenziwa ngekhowudi ye-M, kwaye uluhlu oluphezulu ludla ngokudibana noluhlu olusezantsi. Kwiziko lokujika elinoluhlu lwe-spindle ezintathu, igiya eliphantsi linokuhambelana ne-M41 kwaye isantya singu-30-1,400 rpm, igiya eliphakathi linokuhambelana ne-M42, kwaye isantya singu-40-2,800 rpm, kwaye igiya eliphezulu linokuhambelana ne-M43 kwaye isantya singu-45-4,500 rpm.
Oku kusebenza kuphela kumaziko okujika kunye nemisebenzi esebenzisa isantya somphezulu esingaguqukiyo. Xa isantya somphezulu singaguquki, i-CNC iya kukhetha isantya (rpm) ngokuqhubekayo ngokwesantya somphezulu esichaziweyo (iinyawo okanye i-m/min) kunye nobubanzi obucutshungulwayo ngoku.
Xa useta i-feedrate ngokujikeleza ngakunye, isantya se-spindle silingana ngokuphambeneyo nexesha. Ukuba ungasiphinda kabini isantya se-spindle, ixesha elifunekayo kwimisebenzi yoomatshini enxulumeneyo liya kunqunyulwa phakathi.
Umthetho oqhelekileyo wokukhetha uluhlu lwe-spindle kukurhangqa kuluhlu oluphantsi kunye nokugqiba kuluhlu oluphezulu. Nangona lo ngumthetho olungileyo wokuqinisekisa ukuba i-spindle inamandla aneleyo, ayisebenzi kakuhle xa kujongwa isantya.
Cinga ngesixhobo sokusebenza esinobubanzi obuyi-intshi enye ekufuneka sijike kancinci kwaye sijike kancinci. Isantya esicetyiswayo sesixhobo sokugoba yi-500 sfm. Nokuba sinobubanzi obuphezulu (i-intshi enye), siya kuvelisa i-1,910 rpm (3.82 ephindwe kayi-500 yahlulwe ngo-1). Ububanzi obuncinci buya kufuna isantya esiphezulu. Ukuba umhleli wenkqubo ukhetha uluhlu oluphantsi ngokusekelwe kumava, i-spindle iya kufikelela kumda we-1,400 rpm. Ukuba amandla aneleyo, umsebenzi wokugoba uya kugqitywa ngokukhawuleza kuluhlu oluphezulu.
Oku kusebenza kuphela kwiindawo zokujika kunye nemisebenzi yokurhangqa efuna isantya esiqhubekayo somphezulu. Cinga ngokujika ngokurhangqa umngxuma onobubanzi obuziisentimitha ezi-4 onobubanzi obuninzi, omncinci kuwo oyi-intshi e-1. Cinga ukuba isantya esicetyiswayo yi-800 sfm. Kwi-intshi ezi-4, isantya esifunekayo yi-764 rpm. Uluhlu oluphantsi luya kubonelela ngamandla afunekayo.
Njengoko ukurhawulwa kuqhubeka, ububanzi buya buncipha kwaye isantya siyanda. Kwi-intshi eziyi-2.125, umatshini ofanelekileyo kufuneka udlule kwi-1,400 rpm, kodwa i-spindle iya kufikelela kwinqanaba eliphantsi le-1,400 rpm, kwaye inkqubo nganye yokurhawulwa eqhubekayo iya kuthatha ixesha elide kunokuba kufanele. Kuya kuba bubulumko ukutshintshela kuluhlu oluphakathi ngeli xesha, ingakumbi ukuba utshintsho loluhlu luyenzeka ngoko nangoko.
Xa inkqubo ingena kumatshini, naliphi na ixesha eligciniweyo ngokutsiba amalungiselelo enkqubo linokulahleka lula. Nceda ulandele la manyathelo angezantsi ukuqinisekisa impumelelo.
Iiparameters zixelela i-CNC zonke iinkcukacha zesixhobo esithile somatshini esisetyenziswayo kunye nendlela yokusebenzisa zonke iimpawu kunye nemisebenzi ye-CNC.
