Funda ukuthi ungakhetha kanjani uhla lwe-spindle olufanele futhi uqinisekise ukuthiIsikhungo sokulungisa imishini se-CNCnoma isikhungo sokujika siqhuba umjikelezo olungiselelwe kahle. #cnctechtalk
Kungakhathaliseki ukuthi usebenzisaUmshini wokugaya we-CNCngethuluzi lokujikeleza i-spindle nomaI-CNC latheNgomshini wokusebenza ojikelezayo we-spindle, amathuluzi amakhulu omshini we-CNC anezinhlobo eziningi ze-spindle. Ububanzi be-spindle obuphansi bunikeza amandla engeziwe, kanti ububanzi obuphezulu bunikeza isivinini esiphezulu. Kubalulekile ukuqinisekisa ukuthi imishini iqediwe ngaphakathi kobubanzi besivinini se-spindle obufanele ukuze kufezwe umkhiqizo omuhle kakhulu. Nazi amathiphu amahlanu okukhetha ububanzi obufanele:
Abakhiqizi bamathuluzi omshini bashicilela izici ze-spindle ezincwadini zabo zokusebenza. Lapho uzothola i-rpm encane nephezulu yebanga ngalinye, kanye namandla alindelekile kulo lonke ibanga le-rpm.
Uma ungakaze ufunde le datha ebalulekile, isikhathi sakho sokujikeleza cishe asilungiswanga kahle. Okwenza izinto zibe zimbi kakhulu, ungase ubeke ingcindezi enkulu ku-spindle motor yomshini, noma uyimise. Ukufunda incwadi yemiyalelo nokuqonda izici ze-spindle kungakusiza ukuthi uthuthukise umkhiqizo womshini wakho.
Kunezinhlelo okungenani ezimbili zokushintsha ububanzi be-spindle: eyodwa uhlelo olunenjini ye-spindle drive enama-wind amaningi, kanti enye uhlelo olune-mechanical drive.
Owokuqala ushintsha ububanzi ngogesi ngokushintsha ama-motor windings abawasebenzisayo. Lezi zinguquko cishe zishesha kakhulu.
Uhlelo olune-mechanical transmission luvame ukushayela ngqo ebangeni lalo eliphezulu kakhulu futhi lubambe i-transmission ebangeni eliphansi. Ushintsho lwebanga lungathatha imizuzwana embalwa, ikakhulukazi lapho i-spindle kumele ime phakathi nenqubo.
Ku-CNC, ushintsho lobubanzi be-spindle lubonakala kancane, ngoba ijubane le-spindle lichazwe nge-rpm, kanti igama elithi S lejubane elicacisiwe lizokwenza umshini ukhethe ububanzi be-spindle obufanele. Ake sithi ububanzi bejubane eliphansi lomshini bungu-20-1,500 rpm, kanti ububanzi bejubane eliphezulu bungu-1,501-4,000 rpm. Uma ucacisa igama elithi S le-S300, umshini uzokhetha ububanzi obuphansi. Igama elithi S le-S2000 lizokwenza umshini ukhethe ububanzi obuphezulu.
Okokuqala, uhlelo lungabangela izinguquko ezingadingekile kububanzi obuphakathi kwamathuluzi. Ngokudluliswa kwemishini, lokhu kuzokwandisa isikhathi somjikelezo, kodwa kungase kunganakwa ngoba kubonakala kuphela uma amanye amathuluzi ethatha isikhathi eside ukushintsha kunamanye. Amathuluzi okusebenzisa adinga ububanzi obufanayo ngokulandelana azonciphisa isikhathi somjikelezo.
Okwesibili, ukubalwa kwejubane le-spindle rpm kwemisebenzi enamandla yokubhoboza kungabeka i-spindle ekugcineni okuphansi kobubanzi be-spindle obuphezulu, lapho amandla elinganiselwe khona. Lokhu kuzofaka ingcindezi enkulu ohlelweni lwe-spindle drive noma kubangele ukuthi i-spindle motor ime. Umhleli onolwazi uzonciphisa kancane ijubane le-spindle futhi akhethe ijubane eliphakeme kakhulu kububanzi obuphansi, lapho kunamandla anele okwenza umsebenzi womshini.
Esikhungweni sokujika, ushintsho lwebanga le-spindle lwenziwa ngekhodi ye-M, futhi ibanga eliphakeme livame ukugoqana nebanga elingaphansi. Esikhungweni sokujika esinebanga le-spindle elinezinti ezintathu, igiya eliphansi lingahambisana ne-M41 futhi ijubane lingu-30-1,400 rpm, igiya eliphakathi lingahambisana ne-M42, kanti ijubane lingu-40-2,800 rpm, kanti igiya eliphezulu lingahambisana ne-M43 futhi ijubane lingu-45-4,500 rpm.
Lokhu kusebenza kuphela ezikhungweni zokujika kanye nemisebenzi esebenzisa isivinini sobuso esingaguquki. Uma isivinini sobuso singaguquki, i-CNC izohlala ikhetha isivinini (rpm) ngokuya ngesivinini sobuso esibekiwe (izinyawo noma i-m/min) kanye nobubanzi obucutshungulwa njengamanje.
Uma usetha izinga lokuphakelwa ngokujikeleza ngakunye, ijubane le-spindle lilingana nesikhathi ngokuphambene. Uma ungakwazi ukuphinda kabili ijubane le-spindle, isikhathi esidingekayo semisebenzi yokugaya ehlobene sizonqunywa phakathi.
Umthetho odumile wokukhetha ububanzi be-spindle ukugoqa endaweni ephansi kanye nokuqeda endaweni ephezulu. Nakuba lokhu kuwumthetho omuhle wokuqinisekisa ukuthi i-spindle inamandla anele, ayisebenzi kahle uma kucatshangelwa isivinini.
Cabanga ngomshini wokusebenza ongu-1 intshi ububanzi okumele uguqulwe ube lukhuni futhi uguqulwe kahle. Isivinini esinconywayo sethuluzi lokugoqa singama-sfm angu-500. Ngisho noma ububanzi obukhulu (1 intshi), buzokhiqiza i-1,910 rpm (3.82 izikhathi ezingu-500 zihlukaniswe ngo-1). Ububanzi obuncane buzodinga isivinini esiphezulu. Uma umhleli ekhetha ububanzi obuphansi ngokusekelwe kokuhlangenwe nakho, i-spindle izofinyelela umkhawulo we-1,400 rpm. Uma sicabanga ngamandla anele, umsebenzi wokugoqa uzoqedwa ngokushesha ebangeni eliphezulu.
Lokhu kusebenza kuphela ezindaweni zokujika kanye nemisebenzi yokugoqa edinga isivinini esiqhubekayo somphezulu. Cabanga ngokujika ngokugoqa umshafti ongu-4 intshi ububanzi one-diameter eziningi, omncane kunayo wonke ongu-1 intshi. Ake sithi isivinini esinconywayo singu-800 sfm. Ku-4 intshi, isivinini esidingekayo singu-764 rpm. Ububanzi obuphansi buzohlinzeka ngamandla adingekayo.
Njengoba ukugoqa kuqhubeka, ububanzi buba buncane futhi isivinini siyanda. Ku-2.125 amayintshi, umshini ofanele wokugaya udinga ukudlula u-1,400 rpm, kodwa i-spindle izofinyelela ebangeni eliphansi lika-1,400 rpm, futhi inqubo ngayinye yokugoqa eqhubekayo izothatha isikhathi eside kunalokho okufanele ibe yikho. Kungaba ukuhlakanipha ukushintshela ebangeni eliphakathi ngalesi sikhathi, ikakhulukazi uma ushintsho lwebanga lushesha.
Uma uhlelo lungena emshinini, noma yisiphi isikhathi esilondolozwa ngokweqa ukulungiselela uhlelo singalahleka kalula. Sicela ulandele izinyathelo ezingezansi ukuqinisekisa impumelelo.
Amapharamitha atshela i-CNC yonke imininingwane yethuluzi lomshini elithile elisetshenziswayo nokuthi zisetshenziswa kanjani zonke izici nemisebenzi ye-CNC.
