Mhando dzezvidhinha zvinogona kushandiswaMichina yekuboora nekugaya yeCNCzvinosanganisira mabhora ekukwesha, mabhora ekudhonza eU, mabhora ekudhonza ane simba, uye mabhora ekudhonza epakati.
Mabhora ekudhirowa anotenderera anonyanya kushandiswa mumabhodhi ekudhirowa ane musoro mumwe chete kuti adhirowe mapaneru ari nyore. Iye zvino haawanzoonekwi muvagadziri vemabhodhi makuru edunhu, uye kudzika kwawo kwekudhirowa kunogona kusvika kagumi kupfuura dhayamita yebhora.
Kana substrate stack isiri yakakwira, kushandisa ma drill sleeves kunogona kudzivirira kutsauka kwekuboorwa.Muchina wekuchera weCNCinoshandisa drill yakagadzirwa nekabhoni yakagadzirwa nesimbi, iyo inoratidzwa nekukwanisa kutsiva drill otomatiki. Kurongeka kwakanyanya, hapana chikonzero chekushandisa maoko ekuboorera. Angle hombe yehelix, kukurumidza kubvisa chip, yakakodzera kucheka nekukurumidza. Mukati mehurefu hwese hwechip flute, dhayamita yechiboorera i inverted cone, uye kukweshana nemadziro egomba panguva yekuboorera kudiki, uye mhando yekuboorera yakanyanya. Madhayamita akajairika echiboorera i3.00mm ne3.175mm.
Chidimbu chekuboorera chetube sheet chinowanzo shandisa simende carbide, nekuti epoxy glass cloth copper foil plate inopfeka chishandiso nekukurumidza. Iyo inonzi simende carbide inogadzirwa netungsten carbide powder se matrix uye cobalt powder se binder kuburikidza nekumanikidzwa uye sintering. Inowanzova ne 94% tungsten carbide uye 6% cobalt. Nekuda kwekuoma kwayo kwakanyanya, haipfeki zvakanyanya, ine simba rakati, uye yakakodzera kucheka nekukurumidza.
Kusimba kwakashata uye kutetepa zvakanyanya. Kuti vawedzere kushanda kwecarbide yakagadzirwa nesimende, vamwe vanoshandisa layer ye5-7 microns ye extra-hard titanium carbide (TIC) kana titanium nitride (TIN) pa carbide substrate ne chemical vapor deposition kuti ive nekuomarara kwakanyanya. Vamwe vanoshandisa tekinoroji ye ion implantation kuisa titanium, nitrogen, uye carbon mu matrix kusvika pakadzika, izvo zvisingangogadzirisi kuomarara uye simba, asiwo zvikamu izvi zvinoiswa zvinogona kufamba mukati kana drill bit yadzorerwa pasi. Vamwe vanoshandisa nzira dzepanyama kugadzira layer yedhaimani firimu pamusoro pechibooreso, izvo zvinovandudza zvikuru kuomarara uye kuramba kupfeka kwechikamu chekuboorera. Kuomarara uye simba recarbide yakagadzirwa nesimende hazvina chekuita chete nehuwandu hwetungsten carbide necobalt, asiwo nezvidimbu zvehupfu.
Kune zvidimbu zvitete zvema drill bits akachekwa simende, avhareji yehukuru hwe tungsten carbide phase grains iri pasi pe 1 micron. Rudzi urwu rwe drill haruna kungova nekuoma kwakanyanya chete asiwo rwakawedzera simba rekumanikidza uye kusimba kwe flexural. Kuti vachengetedze mari, ma drill bits mazhinji ikozvino anoshandisa welded shank structure. Bhodhi rekutanga re drill rakagadzirwa ne hard alloy yese. Iye zvino drill shank yekumashure yakagadzirwa ne steel stainless, izvo zvinoderedza mutengo zvakanyanya. Zvisinei, nekuda kwekushandiswa kwezvinhu zvakasiyana, dynamic concentricity haina kunaka se hard hard. Alloy drill bits, kunyanya kune diki dhayamita.
