Mhando dzema drill bits anogona kushandiswaCNC yekuchera uye milling michinazvinosanganisira twist drills, U drills, chisimba drills, uye core drills.
Twist drills anonyanya kushandiswa mumashini e-single-head drill kudhiza zviri nyore mapaneru.Iye zvino havasati vaonekwa mumagetsi makuru ekugadzira bhodhi, uye kudzika kwavo kwekuchera kunogona kusvika 10 nguva yedhayamita ye drill.
Kana iyo substrate stack isiri yakakwirira, kushandiswa kwechibooreso chemaoko kunogona kudzivirira kudhirowa kutsauka.TheCNC yekuchera muchinainoshandisa simende carbide yakagadziriswa shank drill, iyo inoratidzirwa nekugona kutsiva dhiri.High positioning accuracy, hapana chikonzero chekushandisa drill sleeves.Hombe helix angle, inokurumidza chip yekubvisa kumhanya, yakakodzera kucheka-kumhanya.Mukati mehurefu hwakazara hwe chip flute, iyo dhayamita yedhiri iine inverted koni, uye friction ine gomba madziro panguva yekuchera idiki, uye kudhirowa kwemhando yakakwirira.Common drill shank diameters ndeye 3.00mm uye 3.175mm.
Iyo yekuboora chubhu yepepa yekuchera inowanzo shandisa simende carbide, nekuti epoxy girazi jira rakavharwa ndiro yemhangura foil inopfeka chishandiso nekukurumidza.Iyo inonzi cemented carbide inogadzirwa ne tungsten carbide poda sematrix uye cobalt poda sebhainda kuburikidza nekumanikidza uye sintering.Kazhinji ine 94% tungsten carbide uye 6% cobalt.Nekuda kwekuoma kwayo kwakakwirira, inonyatso pfeka, ine simba rakati, uye inokodzera kucheka kwekukurumidza.
Hurombo kuoma uye brittle kwazvo.Kuti vavandudze mashandiro ecemented carbide, vamwe vanoshandisa layer ye5-7 microns yeextra-hard titanium carbide (TIC) kana titanium nitride (TIN) pacarbide substrate nekemikari vapor deposition kuti ive Yakanyanya kuoma.Vamwe vanoshandisa ion implantation tekinoroji kuisa titanium, nitrogen, uye kabhoni mumatrix kune imwe kudzika, izvo zvisingangogadziri kuomarara uye kusimba chete, asiwo izvi zvikamu zvakasimwa zvinogona kutamira mukati kana chibooreso chave pasi.Vamwe vanoshandisa nzira dzemuviri kuti vagadzire dhaimondi firimu pamusoro pedrill bit, iyo inovandudza zvakanyanya kuoma uye kupfeka kusagadzikana kwechibooreso.Kuoma uye kusimba kwecemented carbide haisi kungoenderana chete nechiyero che tungsten carbide uye cobalt, asiwo kune zvikamu zvehupfu.
Kune ma-ultra-fine particles ecemented carbide drill bits, avhareji saizi ye tungsten carbide phase tsanga iri pazasi 1 micron.Rudzi urwu rwekubooresa haruna kuomarara kwepamusoro chete asiwo rwakanatsiridza kumanikidza uye kuchinjika simba.Kuti uchengetedze mutengo, mabheti mazhinji eku drill ikozvino anoshandisa welded shank chimiro.Iyo yekutanga drill bit inogadzirwa neyakaoma alloy yakazara.Iye zvino dhiri rekuchera shank rakagadzirwa nesimbi isina tsvina, iyo inoderedza zvikuru mari.Nekudaro, nekuda kwekushandiswa kwezvinhu zvakasiyana, iyo dynamic concentricity haina kunaka seyakaomarara.Alloy drill bits, kunyanya kune madhayamita madiki.
