Kuchera chikamu chakakosha che PCB contour kugadzira tekinoroji, uye kusarudzwa kwechibhorani zvishoma kunonyanya kukosha. Iyo welded carbide bit, inozivikanwa nekukwirisa kwayo kwakasimba simba pakati pekuboora tip uye cheka mutumbi, inogona kugadzirisa maburi neakanaka pamusoro peyakaomarara, diki yekuzorora kushivirira uye yakakwirira nzvimbo kunyatso. Kana iyo yekukiya sikuru iri yakasungwa, korona chibooreso inogona kusvika senge yakakwira chikafu senge iyo yekutenderera ikati.

Vanhu vazhinji vanotenda zvisirizvo kuti kuchera kunofanirwa kuitwa nemazinga akaderera ezvipfuyo uye nekumhanya kwakaderera. Izvi zvaimbove zvechokwadi, asi yanhasi carbide bits mairi imwe nyaya. Muchokwadi, kusarudza iyo diki diki kunogona kuwedzera zvakanyanya kugadzirwa uye kudzikisira mutengo pahomwe mubhodhi.

Kune mhando ina dzekutanga dzekuboora mabhatiri ane carbide yekucheka mativi anowanikwa kune wekupedzisira mushandisi: solid carbide, indexable inoisa, welded carbide drill matipi, uye anochinjika carbide drill matipi. Imwe neimwe ine zvayakanakira mune imwe application.

Yekutanga yakasimba carbide mabheti anoshandiswa mune dzemazuva ano machining nzvimbo. Yakagadzirwa kubva kune yakaomeswa carbide uye yakaputirwa neTIAlN yehupenyu hwechishandiso, mabhii anozvifunga anopa yakanakisa chip kudzora uye kubviswa mune akawanda mashopu ekushandisa nekuda kwenzvimbo dzakatemwa dzakatemwa. Iyo yega-inokoshesa geometry uye nemazvo kweakakosha carbide mabithi anovimbisa kuti emhando yepamusoro maburi anowanikwa pasina kumwe kumwe kugadzirwa.

Indexable blade bits inovhara madhaimendi akasiyana siyana pakadzika kubva pa2XD kusvika pa5XD. Ivo vanogona kushandiswa mune ese rotary kunyorera uye lathes. Aya mabhii anoshandisa iyo yega-inokoshesa geometric Angle yezvizhinji zvekushandira zvigadzirwa kudzikisa kutema simba uye nekupa yakanaka chip kutonga.

Iyo yakasungwa chibooreso yakarongedza maburi ane akakwirira akadzika pamusoro pekupedzisa, kukwirira kwemhando yepamusoro uye yakanaka chinzvimbo kunyatso pasina kumwe kupedzisa. Nekutonhora kuburikidza nemakomba, welded bit matipi anogona kushandiswa mune machining nzvimbo, CNC lathes, kana zvimwe zvemuchina maturusi ane kukwana kwakaringana uye kutenderera kumhanya.

Iyo yekupedzisira bit fomu inosanganisa simbi yekucheka muviri ine inobviswa solid carbide poindi inonzi korona. The chibooreso inopa chete nemazvo sezvo welded ikakuruma apo kuwana dzakakwirira negoho panguva yakaderera machine mutengo. Ichi chizvarwa chinotevera chinoruma nekarbide korona inopa chaiyo yekuvhenekera kuwedzera uye inozvifunga-yega geometric Angle iyo inovimbisa yakakwira yekuyera chaiyo.

Nyatso tarisa kushivirira uye muchina chishandiso kugadzikana

Iyo fekitori inofanirwa kusarudza iyo diki zvinoenderana nematanho chaiwo pane iyo machining. Makomba madiki ehupamhi anowanzo kuve nekutsungirira kusimba. Nekudaro, vagadziri vevhudzi vanopatsanura mabiti nekutsanangura kuzarura kwemazita uye kushivirira kwepamusoro. Pamhando dzese dzekuboora, iyo yakasimba carbide bit ine kushatisisa kushivirira. Izvi zvinovaita sarudzo yakanakisa yekuchera maburi ane kushivirira kwakanyanya. Iyo fekitori inogona kuchera ne10mm dhayamita yakasimba carbide zvishoma nekushivirira kubva pa0 kusvika + 0.03mm.

Kune rimwe divi, maburi akasungwa kana akakwirira mabhureti ane chinotsiviwa carbide korona inogona kudhonzwa kune shiviriro kubva ku0 kusvika + 0.07mm. Aya mabheti anowanzo kuve sarudzo yakanaka yekuchera maitiro ekugadzira.Indexable blade bit ibasa rinorema pabasa muindasitiri. Nepo mutengo wavo wepamberi uri kazhinji wakaderera pane mamwe mabheti, zvakare vane kushivirira kukuru, kubva pa0 kusvika + 0.3mm zvichienderana nehupamhi-kusvika-mugomba kudzika reshiyo. Izvi zvinoreva kuti mushandisi wekupedzisira anogona kushandisa anonongedzeka blade bit kana kushivirira kwegomba kukwirira, zvikasadaro ivo vanofanirwa kuve vakagadzirira kupedzisa gomba nemutambi unonetesa. Pamwe pamwe nemakomba anoshivirira, iyo fekitori inofanirwa kufunga nezve kudzikama kwechishina chishandiso mune yekusarudza maitiro. Nekuti kugadzikana kuve nechokwadi chishandiso hupenyu uye kuchera chaiko. Iyo fekitori ichaongorora mamiriro emuchina spindles, zvigadziriso nezvimwe zvinhu. Ivo vanofanirwa zvakare kufunga nezve kudzikama kwechetere. Semuenzaniso, monolithic carbide bits inopa kuomarara kwakaringana, iyo inobvumidza kukwirisa kwepamusoro.

Kune rimwe divi, indexable blade bits inowanzo tenderera. Aya mabheti akavezwa nemazamu maviri – chipenga chemukati pakati uye chipasa chinotambanuka chekunze kubva mukati memukati kusvika kumucheto – uye pakutanga rimwe chete banga rinotora chikamu mukucheka. Izvi zvinogadzira kusagadzikana mamiriro izvo zvinoita kuti iyo diki muviri itsauke. Uye chikuru kutsauka kwemwedzi kwemwedzi. Naizvozvo, kana uchishandisa 4XD uye mamwe anonetseka mabhii mabhii, chirimwa chinofanira kufunga nezvekudzikisa chikafu chekutanga mm uye nekuwedzera chikafu kune zvakajairwa. Iyo yakasungwa simbi uye inoshandurwa korona zvishoma inogadzirwa semaviri machekacheka ekucheka mativi ayo anoumba inozvimirira-yega geometric Angle. Iyi yakagadzika yekucheka dhizaini inobvumira iyo diki kuti ipinde iyo yekushandira nekumhanya kuzere. Icho chete chinosarudzika ndechekuti iyo bit haina kutarisisa kune iyo pasi iri kugadzirwa. Inokurudzirwa kudzikisa chikafu ne30% kusvika 50% panguva yekucheka nekucheka.

Iyo simbi inoruma muviri inobvumira kushomeka kudiki, ichigonesa kuti ishandiswe zvinobudirira pane lathes. Iyo yakasimba carbide inoruma ine yakanaka kuomarara inogona kuputswa nyore, kunyanya kana iyo workpiece isina kukosheswa zvakanaka. Usaregeredza machipisi mafekitori mazhinji ane matambudziko nekubvisa chip. Muchokwadi, kubviswa kwechipu kwakashata ndiro dambudziko rakajairika mukuchera, kunyanya kana uchinge wagadzira simbi nyoro. Uye hazvina basa kuti chibhorani chaunoshandisa chii. Mafekitori anowanzo shandisa kutonhora kwekunze kugadzirisa dambudziko iri, asi chete kune yakadzika maburi isingasviki 1XD uye nemipimo yakatemwa yekucheka. Zvikasadaro, ivo vanofanirwa kushandisa inotonhorera chaiyo kuti ifananidze kuyerera uye kumanikidza kwekuvhurika. Kune zvishandiso zvemuchina izvo zvisina spindle yepakati kutonhora, iyo fekitori inofanirwa kushandisa inotonhorera kunze kune mudziyo. Rangarira, iyo yakadzika gomba, zvinonyanya kuomesa kubvisa machipisi uye nekuwedzera kutonhora kumanikidza kunodiwa. Nguva dzose tarisa zvigadzirwa zvinokurudzirwa zvishoma zvinotonhorera zvemugadziri. Pakuderera kwekuyerera mitengo, yakaderedzwa feed inogona kudikanwa. Kuongorora hupenyu hwekutenderera kunodhura kugadzirwa kana mutengo pahomwe ndeimwe yematanho makuru anokanganisa kudhiraira nhasi. Izvi zvinoreva kuti vagadziri vebiti vanofanirwa kutsvaga nzira dzekubatanidza mamwe maitiro uye kukudziridza mabiti anogona kutakura akakwira mafura mareti uye akakwira-mhanyisa machining.

Iyo yazvino mabheti ane anochinjika solid carbide matipi anopa epamusoro hupfumi. Panzvimbo pekutsiva muviri wese mudiki, mushandisi wekupedzisira anotenga chete carbide musoro iyo inodhura zvakafanana nekugadzirisa zvakare yakasungwa kana yakasimba kabhidhi bhiti. Aya korona anotsiviwa nyore uye akanyatsojeka, achibvumira iyo fekitori kuti ishandise akawanda korona pane imwechete muviri muviri kuchera huwandu hwakasiyana huwandu hwemakomba. Iyi modular yekuchera sisitimu inoderedza yeinodhura mitengo yemabiti ane maamitha kubva ku12mm kusvika 20mm.

Uye zvakare, iyo inobvisa mutengo wekuve ne backup chidiki kana iyo yakasungwa biti kana yakasimba carbide bit iri reground. Iyo fekitori inofanirwa zvakare kufunga nezve huwandu hwese hweturu kana ichiongorora mutengo pahomwe. Kazhinji, kamwe kabhidhi kabhidhi inogona kuumbika kanomwe kusvika kagumi mufekitori, nepo chakasungwa chidiki chinogona kudzokororwa katatu kana kana. Crown drill bits, kune rimwe divi, iine simbi yekucheka muviri iyo inogona kutsiva ingangoita makumi maviri kusvika makumi matatu korona ichiri kugadzira simbi.

Iko zvakare kune mubvunzo wekugadzirwa. Welded kana yakasimba carbide mabheti anofanira kunge akatenderedzwa; Naizvozvo, mafekitori anowanzo deredza kumhanya kunzvenga anonamira machipisi. Nekudaro, iyo inotsiviwa zvishoma haidi kuti itenderedzwe, saka iyo fekitori inogona kugadzirisa pamwe nekudya kwakaringana uye nekumhanyisa pasina kunetseka nezve cemented carbide chip.
