Iri gwara rakazara rinoenzanisa makumi maviri neshanu akajairika zvinhu zvinoshandiswa muCNC machining uye inokubatsira kusarudza iyo yakakodzera yekushandisa kwako.
CNC machining inogona kugadzira zvikamu kubva kune chero simbi kana plastiki.Izvi zvazvakadaro, kune huwandu hukuru hwezvinhu zviripo kune zvikamu zvinogadzirwa kuburikidza neCNC milling uye kutendeuka.Kusarudza iyo yakakodzera yekushandisa kwako kunogona kuve kwakaoma, uye kunzwisisa zvakanakira uye mashandisiro akanaka echinhu chimwe nechimwe chiripo kunogona kukosha.
Muchinyorwa chino, isu tinofananidza akajairika CNC zvinhu, maererano nemakanika uye ekupisa zvivakwa, mutengo uye zvakajairwa (uye zvakaringana) zvikumbiro.
Iwe unosarudza sei iyo chaiyo CNC zvinhu?
Paunenge uchigadzira chikamu kuti ive CNC muchina, kusarudza zvinhu zvakanaka kwakakosha.Heano matanho ekutanga atinokurudzira kutevedzera kuti usarudze zvinhu zvakanaka zvezvikamu zvako zvetsika.
Tsanangura izvo zvinodikanwa zvezvinhu: Izvi zvinogona kusanganisira zvemuchina, zvinopisa kana zvimwe zvinhu zvinodiwa, pamwe nemutengo uye kupera kwepasi.Funga nezve mashandisiro auchange uchishandisa zvikamu zvako uye kuti imhando ipi yenzvimbo yavanenge vari.
Ziva zvinhu zvemumiriri: Pinira pasi mashoma emumiriri zvinhu zvinozadzisa zvese (kana zvakawanda) zvezvaunoda dhizaini.
Sarudza iyo yakanyatsokodzera zvinhu: Chibvumirano chinowanzodiwa pano pakati pezviviri kana kupfuura zvezvinodiwa zvekugadzira (semuenzaniso, mashandiro emuchina uye mutengo).
Muchikamu chino, tichatarisa padanho rechipiri.Uchishandisa ruzivo rwuri pazasi, unogona kuona zvinhu zvakanyanyokodzera chikumbiro chako, uchichengeta purojekiti yako pabhajeti.
Ndeapi mazano eHubs ekusarudza zvinhu zveCNC?
Mune matafura ari pazasi, isu tinopfupikisa hunhu hwakakodzera hweakajairika CNC zvinhu, zvakaunganidzwa nekuongorora madheti akapihwa nevagadziri vezvinhu.Isu tinotsemura simbi nemapurasitiki kuita mapoka maviri akasiyana.
Simbi dzinonyanya kushandiswa mumashandisirwo anoda simba rakakwirira, kuoma uye kupikisa kupisa.Mapurasitiki zvinhu zvakareruka zvine huwandu hwakawanda hwezvinhu zvemuviri, zvinowanzo shandiswa kupikisa kwavo kwemakemikari uye kugona kwemagetsi ekudzivirira.
Mukuenzanisa kwedu CNC zvinhu, isu tinotarisa kune simba remagetsi (rinoratidzwa seyakasimba goho simba), machinability (kureruka kwekugadzira kunokanganisa CNC mitengo), mutengo, kuoma (kunyanya simbi) uye kupisa kwekushisa (kunyanya kumapurasitiki).
Heino infographic iyo iwe yaunogona kushandisa sechimbichimbi rengedzo yekukurumidza kuona CNC zvinhu zvinoenderana nezvinodiwa zveinjiniya:
