Chida cha CNC: Popanga chipangizo chokhomerera, kutsimikiza kwa mphamvu yolumikizira kumaphatikizapo zinthu zitatu: komwe kumenyera mphamvu, komwe kumagwirira ntchito komanso kukula kwa mphamvu yolumikizira.
1. Chitsogozo cha mphamvu ya clamping ya chida cha CNC Chitsogozo cha mphamvu ya clamping chikugwirizana ndi kasinthidwe koyambira kayimidwe ka zigawo zing'onozing'ono ndi njira ya mphamvu yakunja pa workpiece.
Tsatirani malangizo awa posankha zida za CNC:
① Kayendetsedwe ka mphamvu yokhotakhota kuyenera kukhala kokhazikika, ndipo mphamvu yayikulu yotchingira iyenera kulunjika pomwe pali maziko.
②Mayendedwe a clamping force akuyenera kukhala othandiza kuchepetsa mphamvu yotchinga kuti muchepetse kusinthika kwa chogwirira ntchito ndikuchepetsa mphamvu yantchito.
③Mayendedwe a mphamvu yopondera kuyenera kukhala komwe kuli kokhazikika kwa chogwiriracho. Popeza kuuma kwa workpiece m'njira zosiyanasiyana sikufanana, malo osiyanasiyana ogwiritsira ntchito mphamvu amawonongekanso mosiyana chifukwa cha kukula kwa malo okhudzana. Makamaka pamene clamping mbali woonda-mipanda, chisamaliro ayenera kumwedwa kuti malangizo a clamping mphamvu kuloza ku mbali ya rigidity wa workpiece.
2. Malo ochitirapo mphamvu ya clamping ya chida cha CNC Malo ogwirira ntchito a clamping force amatanthauza kadera kakang'ono komwe gawo lotsekera limalumikizana ndi chogwirira ntchito. Vuto losankhira malo ochitirapo kanthu ndikuzindikira malo ndi kuchuluka kwa clamping force action point pansi pamikhalidwe yoti kuwongolera kwakhazikika. Kusankhidwa kwa clamping Force point ndiye chinthu chomwe chimapangitsa kuti pakhale malo abwinoko, ndipo kusankha koyenera kwa clamping Force point kumatsatira mfundo izi:
200 Mtengo wa roughness wa pogayo umachepetsedwa kuchokera ku 2.0 mpaka 1.1 CNC chida
3. Kugwiritsa ntchito mphamvu kwa CNC chida processing ndi otsika, kupulumutsa kupanga zinthu. Pamene kudula pa liwiro lalikulu, voliyumu ya kudula wosanjikiza zakuthupi kudula ndi mphamvu unit kumawonjezeka kwambiri. Monga aloyi aloyi ya Lockheed Aircraft Company yodula kwambiri, liwiro la spindle limachokera ku 4 000 1/…. Pamene kuwonjezeka kwa 20 000, mphamvu yodula idatsika ndi 30 ^, pamene chiwerengero cha kuchotsa zinthu chinawonjezeka ndi katatu. Mtengo wochotsa zinthu pa mphamvu ya unit ukhoza kufika 130 ~ 160 (1) kuposa 'kung'amba', pamene mphero wamba ndi 30 'kung'amba. Chifukwa cha kuchuluka kwa kuchotseratu komanso kugwiritsa ntchito mphamvu zochepa, nthawi yopangira ntchito
Ndi lalifupi, limapangitsanso kuchuluka kwa mphamvu zogwiritsira ntchito mphamvu ndi zipangizo, ndipo limachepetsa chiwerengero cha kudula processing muzinthu zopangira zinthu. Chifukwa chake, kudula kothamanga kwambiri kumakwaniritsa zofunikira za njira yachitukuko chokhazikika.
4. Zida za CNC zimachepetsa ndondomekoyi ndikuchepetsa ndalama zopangira. M'zinthu zina, khalidwe lapamwamba la mphero yothamanga kwambiri limafanana ndi kugaya, ndipo mphero yothamanga kwambiri ingagwiritsidwe ntchito mwachindunji monga njira yomaliza yomaliza. Choncho, njira zaumisiri zimakhala zosavuta, mtengo wopangira umachepetsedwa, ndipo phindu lachuma ndi lalikulu.
Zachidziwikire, mphero yothamanga kwambiri ilinso ndi zovuta zina, monga zida zamtengo wapatali ndi zida zamakina (kuphatikiza makina a CNC), zofunika kwambiri pakuchita bwino kwa zida za CNC, komanso moyo wotsika wa spindle.
