Dzidza maitiro ekusarudza iyo chaiyo spindle renji uye simbisa kuti yakoCNC Machining Centerkana turning centre inomhanyisa kutenderera kwakagadziridzwa. #cnctechtalk
Ungave uri kushandisa aCNC milling muchinanechinotenderedza simbi kana aCNC latheine spindle inotenderera workpiece, hombe CNC muchina maturusi ane akawanda spindle siyana. Iyo yakaderera spindle renji inopa simba rakawanda, nepo repamusoro renji rinopa kukurumidza kukurumidza. Izvo zvakakosha kuve nechokwadi chekuti machining anopedzwa mukati meiyo chaiyo spindle yekumhanyisa renji kuti uwane chibereko chakanakisa. Heano matipi mashanu ekusarudza renji rakakodzera:
Vagadziri vezvishandiso zvemuchina vanoburitsa maspindle maitiro mumabhuku avo ekushandisa. Ikoko iwe unowana hushoma uye hwakanyanya rpm kune yega yega renji, pamwe nesimba rinotarisirwa mune yese rpm renji.
Kana usati wambodzidza iyi data yakakosha, nguva yako yekutenderera ingangove isina kugadziridzwa. Kuita kuti zvinhu zvinyanye kuoma, iwe unogona kuisa yakawandisa kudzvanya pane spindle mota yemuchina, kana kutoimisa. Kuverenga bhuku rekushandisa uye kunzwisisa maitiro eiyo spindle kunogona kukubatsira kukwidziridza kugadzirwa kwemuchina wako.
Kune angangoita maviri spindle range shanduko masisitimu: imwe isystem ine akawanda-inotenderera spindle drive mota, uye imwe yacho isystem ine mechanical drive.
Yekutanga inoshandura huwandu hwemagetsi nekuchinja mamhepo emota yavanoshandisa. Shanduko idzi dzinenge dzepakarepo.
Iyo sisitimu ine mechanical transmission inowanzo tyaira yakananga muhukuru hwayo uye inobata kutapurirana munzvimbo yakaderera. Shanduko yemhando inogona kutora masekondi mashoma, kunyanya kana iyo spindle inofanirwa kumira panguva yekuita.
Kune CNC, shanduko yeiyo spindle renji iri pachena, nekuti kumhanya kwespindle kunotsanangurwa mu rpm, uye izwi reS rekumhanya kwakatarwa rinoitawo kuti muchina usarudze wakakodzera spindle renji. Fungidzira kuti yakaderera-yekumhanya siyana yemuchina i20-1,500 rpm, uye yakakwirira-yekumhanya siyana i1,501-4,000 rpm. Kana iwe ukatsanangura S izwi reS300, muchina uchasarudza yakaderera renji. Izwi reS reS2000 rinoita kuti muchina usarudze huwandu hwepamusoro.
Kutanga, chirongwa chinogona kukonzera shanduko dzisina kufanira muchikamu pakati pezvishandiso. Zvekutapurirana zvemuchina, izvi zvinowedzera kutenderera nguva, asi zvinogona kufuratirwa nekuti zvinongobuda pachena kana mamwe maturusi achitora nguva yakareba kuti achinje pane mamwe. Maturusi ekumhanya anoda huwandu hwakafanana mukutevedzana kunoderedza nguva yekutenderera.
Chechipiri, iyo spindle yekumhanyisa rpm kuverenga kwekuita zvine simba roughing inogona kuisa iyo spindle pamucheto wezasi weiyo yakakwira spindle renji, uko simba rakaganhurwa. Izvi zvinopa kudzvanyirira kwakanyanya pane spindle drive system kana kukonzera kuti spindle mota imire. Mugadziri ane ruzivo anozodzikisa zvishoma kumhanya kwespindle uye osarudza iyo yakanyanya kumhanya munzvimbo yakaderera, uko kune simba rakakwana rekuita machining oparesheni.
Kune nzvimbo yekutendeuka, shanduko yemhando ye spindle inoitwa neM kodhi, uye iyo yakakwirira huwandu inowanzo pindirana neiyo yakaderera. Kune nzvimbo yekutendeuka ine matatu-spindle range, iyo yakaderera giya inogona kuenderana neM41 uye kumhanya iri 30-1,400 rpm, iyo yepakati giya inogona kuenderana neM42, uye kumhanya i40-2,800 rpm, uye iyo yakakwirira giya inogona kuenderana. kusvika kuM43 uye kumhanya kuri 45-4,500 rpm.
Izvi zvinoshanda chete kune nzvimbo dzekutendeuka uye maoperation anoshandisa anogara ari pamusoro kumhanya. Kana iyo yekumhanyisa kwepamusoro ichigara, iyo CNC icharamba ichisarudza kumhanya (rpm) zvinoenderana neyakatsanangurwa pamusoro kumhanya (tsoka kana m/min) uye dhayamita riri kugadziriswa parizvino.
Paunoseta feedrate per revolution, iyo spindle yekumhanya inopindirana nenguva. Kana iwe uchikwanisa kupeta kumhanya kwespindle, iyo nguva inodiwa kune inoenderana machining mashandiro inotemwa nepakati.
Mutemo wakakurumbira wechigunwe chekusarudza mutsara wespindle uri roughing mune yakaderera uye kupedzisa mumhando yepamusoro. Kunyangwe uyu uri mutemo wakanaka wegunwe kuti uve nechokwadi chekuti spindle ine simba rakakwana, haiite zvakanaka kana uchifunga nezvekumhanya.
Funga nezve 1-inch dhayamita workpiece iyo inofanirwa kuve yakaoma yakashandurwa uye yakashandurwa zvakanaka. Iyo inokurudzirwa kumhanya kweiyo roughing chishandiso ndeye 500 sfm. Kunyangwe pakureba kwedhayamita (1 inch), inoburitsa 1,910 rpm (3.82 times 500 yakakamurwa ne1). Dhiyamita diki inoda kumhanya kwepamusoro. Kana mugadziri wacho akasarudza yakaderera zvichienderana neruzivo, iyo spindle inosvika painogumira 1,400 rpm. Tichifunga simba rakakwana, roughing operation ichapedzwa nekukurumidza munzvimbo yepamusoro.
Izvi zvinongoshanda chete kune nzvimbo dzekutenderedza uye roughing maoparesheni ayo anoda inogara iri pamusoro kumhanya. Funga rough kushandura 4-inch dhayamita shaft ine madhayamita akawanda, diki yacho iri 1 inch. Fungidzira kuti inokurudzirwa kumhanya i800 sfm. Pa 4 inches, iyo inodiwa inomhanya ndeye 764 rpm. Iyo yakaderera yakawanda ichapa simba rinodiwa.
Sezvo roughing ichienderera mberi, dhayamita inova diki uye kukurumidza kunowedzera. Pa 2.125 inches, iyo optimal machining inoda kudarika 1,400 rpm, asi spindle ichakwira munzvimbo yakaderera ye1,400 rpm, uye imwe neimwe inoenderera roughing process inotora nguva yakareba kupfuura yainofanira kunge iri. Zvingave zvine hungwaru kuchinjika kune yepakati renji panguva ino, kunyanya kana shanduko yekuchinja iri ipapo.
Kana chirongwa chapinda muchina, chero nguva inochengetwa nekusvetuka gadziriro yechirongwa inogona kurasika nyore. Ndapota tevera matanho ari pasi apa kuti uone kubudirira.
Iwo ma paramita anoudza iyo CNC zvese nezve chaiyo muchina chishandiso chiri kushandiswa uye maitiro ekushandisa ese CNC maficha nemabasa.
