Iko kushandiswa kwe twist drills kwakanangana nemaitiro uye mhando.Pamusika, pane zvibooreso zvinomonyorora simbi ine cobalt, parabolic deep-hole twist drills, zvibooreso zvine goridhe zvine goridhe, titanium-plated twist drills, zvibooreso zvesimbi zvinomhanya zvikuru, uye zvekuwedzera kwenguva refu.Chinangwa cheaya mabheti ekudhira kucheka maturusi ekuchera, ayo anogona kushandiswa sekuvaka kongiri kuchera, simbi yekuchera ndiro, yemagetsi indasitiri yekuchera, nezvimwe.
Kuumbwa uye Kugadzirisa Mhedzisiro yeTwist Drills
Twist drillszvinogadzirwa zvinoenderana neyakajairwa twist drills, iyo inosanganisira shank, mutsipa uye chikamu chinoshanda.Kune makona matanhatu ezviboorero, uye makona akasiyana ane mimwe misiyano mukuchera nekugona.Sezvo dhayamita yegomba rakapoteredzwa rakaganhurirwa nedhayamita yegomba, uye nekuti spiral groove inogona kuita kuti chiboore chiite mutete, kuomarara kwegomba rakaboorwa kwakadzikira, kutungamira kwegomba rakacherwa hakuna kujeka, uye axis gomba iri nyore kutsauka.Naizvozvo, zvakaoma kuisa pakati pechisel mupendero uye chibooreso chinofamba, zvichikonzera kukanganisa kukuru muchimiro uye chinzvimbo chegomba.Uye zvakare, nekuti kumberi nekumashure kwakakomberedzwa kwakakombama kweiyo twist drill bit zvakafanana, uye kumberi nekumashure makona ekona yega yega poindi yekucheka kwakasiyana, mamiriro ekucheka haana kunaka uye kumhanya hakuna kuenzana, izvo zvinozopedzisira zvakonzera. iyo drill bit kuti ipfeke uye iko kuchera kwakaderera.Mhedziso yekupedzisira ndeyokuti kukurumidza kwekucheka kunokonzerwa nekavha ye drill bit haisi yunifomu, uye zviri nyore kubudisa spiral debris yakaiswa pane workpiece, uye marara uye gomba remadziro rinobudisa extrusion friction.Pakupedzisira, pamusoro pepasi workpiece yakaoma zvikuru.Saka iyo twist drill ingaboora madziro esimende here?Chii chinogona kubhowa?
1. Dhora simbi
Kuchera simbi kunowanzova demadrill bit, uye chibooreso chinowanzogadzirwa nesimbi yakakwirira-kumhanya.Kazhinji simbi zvinhu (alloy simbi, non-alloy simbi, cast iron, cast simbi, non-ferrous simbi), metalworking drill bits anoshandiswa pamwechete.
Zvisinei, chenjerera kuchera pamusoro pesimbi.Iyo yekumhanyisa haifanirwe kunge yakanyanya kukwirira, zviri nyore kupisa drill bit.Ikozvino kune mamwe magoridhe akaputirwa neasingawanzo simbi yakaoma mafirimu kunze, ayo akagadzirwa nesimbi yemidziyo nezvimwe zvinhu, izvo zvinoomeswa nekupisa kupisa.Iro remuromo rinogadzikwa pamakona akaenzana kumativi ese uye rakadzokororwa zvishoma kuti riite acute edge.Simbi, iron uye aluminium izvo zvisina kuomeswa nekupisa kurapwa.Pakati pazvo, aluminium iri nyore kunamatira kune chibooreso uye inoda kuzorwa nemvura ine sipo pakuchera.
2. Dhonza kongiri
Kuboora maburi pakongiri nematombo, shandisa chibooreso chine chibooreso chematombo, uye musoro wekucheka unowanzo gadzirwa necarbide.Mhuri dzemazuva ose dzinoshandisa chibooreso chemaoko 10mm pane kuchera pamadziro esimende.
3. Dhonza huni
Dhonza maburi muhuni nechibooreso chehuni.Iyo yehuni yekugadzira drill ine yakakura yekucheka vhoriyamu uye haidi yakakwira chishandiso kuoma.Chishandiso chacho chinowanzova simbi inomhanya kwazvo.Kune kapipi kadiki pakati pechibooreso, uye diagonal angles pamativi ese ari maviri akakura, kana kunyange asina kona.Inoshandiswa senzvimbo yakagadziriswa.Kutaura zvazviri, zvibooreso zvesimbi zvinogonawo kuchera huni.Nokuti huni hunopisa nyore nyore uye brittle chips haisi nyore kudhonza kunze, unofanira kunonoka uye kuchenesa machipisi nguva nenguva.
4. Dhonza tile negirazi
Tiledrill bitsanoshandiswa kuchera makomba pamatairi eceramic uye magirazi ane kuoma kwepamusoro.Iyo yekushandisa inogadzirwa ne tungsten-carbon alloy.Nekuti chishandiso chine kuomarara kwakanyanya uye kushomeka kwakashata, chinoda kushandiswa nekumhanya kwakaderera uye pasina kukanganisa.
