Dzidza kusarudza mhando chaiyo yespindle uye iva nechokwadi chekuti yakoCNC machining centrekana nzvimbo yekutendeukira kunharaunda inoita kuti zvinhu zvifambe zvakanaka. #cnctechtalk
Kana uri kushandisaMuchina wekugaya weCNCnechishandiso chinotenderedza spindle kanaCNC latheNechishandiso chekushanda chinotenderera chespindle, maturusi makuru emuchina weCNC ane ma spindle ranges akawanda. Spindle range yakaderera inopa simba rakawanda, nepo high range ichipa kumhanya kwakakwirira. Zvakakosha kuve nechokwadi chekuti machining yapedzwa mukati me spindle speed range yakakodzera kuti uwane goho rakanaka. Heano mazano mashanu ekusarudza ma spindle range akakodzera:
Vagadziri vematurusi emuchina vanoburitsa hunhu hwespindle mumabhuku avo ekushandisa. Ikoko muchawana rpm shoma uye yepamusoro yemhando yega yega, pamwe nesimba rinotarisirwa mumhando yese yerpm.
Kana usati wambodzidza ruzivo urwu rwakakosha, nguva yako yekutenderera ingangove isina kugadziriswa. Zvinotonyanya kuipa, unogona kuisa simba rakawandisa pamota yespindle yemuchina, kana kutoimisa. Kuverenga bhuku rekushandisa uye kunzwisisa hunhu hwespindle kunogona kukubatsira kugadzirisa kugona kwemuchina wako.
Kune masisitimu maviri ekuchinja spindle range: imwe sisitimu ine mota inofambisa spindle ine mavhiri akawanda, uye imwe sisitimu ine mechanical drive.
Yekutanga inochinja mafambiro emagetsi nekuchinja mawinding emota yavanoshandisa. Shanduko idzi dzinoitika pakarepo.
Sisitimu ine mechanical transmission inowanzo fambisa zvakananga munzvimbo yayo yepamusoro uye inobata transmission munzvimbo yakaderera. Kuchinja kwenzvimbo kunogona kutora masekondi mashoma, kunyanya kana spindle ichifanira kumira panguva yekushanda.
Kune CNC, shanduko yenzvimbo yespindle inoonekwa zviri pachena, nekuti kumhanya kwespindle kwakatsanangurwa mu rpm, uye izwi reS rekumhanya kwakataurwa richaitawo kuti muchina usarudze nzvimbo yespindle yakakodzera. Fungidzira kuti nzvimbo yemuchina ine kumhanya kwakaderera i20-1,500 rpm, uye nzvimbo yekukurumidza kwakakwirira i1,501-4,000 rpm. Kana ukatsanangura izwi reS reS300, muchina uchasarudza nzvimbo yekudzikira. Izwi reS reS2000 richaita kuti muchina usarudze nzvimbo yekudzikira.
Chekutanga, chirongwa ichi chinogona kukonzera shanduko dzisina kufanira pakati pezvishandiso. Pakutumira michina, izvi zvichawedzera nguva yekutenderera, asi zvinogona kuregeredzwa nekuti zvinongoonekwa chete kana zvimwe zvishandiso zvichitora nguva yakareba kuti zvichinje pane zvimwe. Kumhanya kwezvishandiso zvinoda huwandu hwakafanana mukutevedzana kunoderedza nguva yekutenderera.
Chechipiri, kuverenga kwespindle speed rpm yekushanda nesimba kwe roughing kunogona kuisa spindle pamucheto wepasi we high spindle range, uko simba riri shoma. Izvi zvinoisa kumanikidzwa kwakanyanya pa spindle drive system kana kukonzera kuti spindle motor imire. Mugadziri wepurogiramu ane ruzivo anoderedza zvishoma kumhanya kwespindle uye osarudza kumhanya kwakanyanya mu low range, uko kune simba rakakwana rekuita machining operation.
Panzvimbo yekutenderedza, shanduko yenzvimbo yekutenderedza inoitiswa nekodhi yeM, uye nzvimbo yepamusoro inowanzo pindirana nenzvimbo yakaderera. Panzvimbo yekutenderedza ine nzvimbo yekutenderedza ine nzvimbo nhatu, giya rakaderera rinogona kuenderana neM41 uye kumhanya kuri 30-1,400 rpm, giya repakati rinogona kuenderana neM42, uye kumhanya kuri 40-2,800 rpm, uye giya repamusoro rinogona kuenderana neM43 uye kumhanya kuri 45-4,500 rpm.
Izvi zvinoshanda chete kunzvimbo dzinotenderedza zvinhu uye mashandiro anoshandisa kumhanya kwenzvimbo kusingachinji. Kana kumhanya kwenzvimbo kusingachinji, CNC inoramba ichisarudza kumhanya (rpm) zvichienderana nekumhanya kwenzvimbo kwakatarwa (tsoka kana m/min) uye dhayamita iri kugadziriswa parizvino.
Kana ukaisa mwero wekudyara pakuchinja kwese, kumhanya kwespindle kunoenderana nenguva. Kana ukakwanisa kuwedzera kaviri kumhanya kwespindle, nguva inodiwa pakushanda kwemashini inosanganiswa ichagurwa nepakati.
Mutemo unonyanya kufarirwa wekusarudza nzvimbo yespindle ndeyekukanda rough muchikamu chidiki uye kupedzisa muchikamu chepamusoro. Kunyangwe uyu uri mutemo wakanaka wekuona kuti spindle ine simba rakakwana, haishande zvakanaka kana tichifunga nezvekumhanya.
Funga nezvebasa re 1-inch dhayamita rinofanira kunge rakatenderedzwa uye rakatenderedzwa zvakanaka. Kumhanya kunokurudzirwa kwechishandiso chekukomba i500 sfm. Kunyangwe padhayamita yepamusoro (1 inch), ichaburitsa 1,910 rpm (3.82 times 500 yakakamurwa ne 1). Dhayamita diki inoda kumhanya kwakanyanya. Kana mugadziri wepurogiramu akasarudza daro rakaderera zvichibva pane zvakaitika, spindle ichasvika muganho we1,400 rpm. Tichifunga kuti simba rakawanda, basa rekukomba richapedzwa nekukurumidza mudaro rakakwirira.
Izvi zvinoshandawo chete kunzvimbo dzekutenderedza uye mabasa ekukombaira anoda kumhanya kwakasimba pamusoro pechinhu. Funga nezvekukombamisa shaft ine dhayamita ye 4-inch ine dhayamita dzakawanda, diki racho riri 1 inch. Ngatitii kumhanya kunokurudzirwa i 800 sfm. Pa 4 inches, kumhanya kunodiwa i 764 rpm. Kureba kwakaderera kuchapa simba rinodiwa.
Sezvo kukweshana kuchiri kuenderera mberi, dhayamita inova diki uye kumhanya kunowedzera. Pa 2.125 inches, michina yakakodzera inofanira kudarika 1,400 rpm, asi spindle ichasvika padanho rakaderera re 1,400 rpm, uye maitiro ese ekukweshana anotora nguva yakareba kupfuura yaanofanira kunge akaita. Zvingave zvakanaka kuchinja kuenda kuchikamu chepakati panguva ino, kunyanya kana shanduko yechikamu ichi ikaitika ipapo ipapo.
Kana purogiramu yapinda mumuchina, chero nguva inochengetwa nekusagadzirira mapurogiramu inogona kurasika zviri nyore. Ndokumbirawo uteedzere matanho ari pazasi kuti uve nechokwadi chekubudirira.
Maparamita acho anoudza CNC zvese zviri muchishandiso chemuchina chiri kushandiswa uye mashandisirwo anoitwa zvese zvinhu zveCNC nemashandiro azvo.
