Matsatsing ana, ho na le mefuta e mengata ea likotoana tsa ho roka mapolanka hoo bareki ba bangata ba sa tsebeng hore na ke mofuta ofe oo ba o hlokang.Sehlooho sena se tla u fa maikutlo a itseng.
Li-Drill tsa Twist.: Li-drill tsa Twist li na le lishanka tsa tšepe tse cylindrical le malebela a lintlha.
Bongata ba li-drill tsa li-blade tse ngata li lekana le lishanka tsa tsona.A liphala tsa helical (tseo ka linako tse ling li bitsoang chip channels) li tsamaea ka mahlakoreng a mabeli ho tse tharo tsa bolelele ba tsona, li sothehile ka har'a shank joalo ka metsero e holim'a palo ea mokuti.
Theko ea twist drill e theko e tlase ho feta likotoana tse ling, empa lesoba la likotoana tse entsoeng ha le nepahale.E sebelisoa ka makhetlo a mangata ka mochini o tlase o bataletseng ho netefatsa ho nepahala.Ka 'mele oa tšepe, li-drill tse sothang ha li khone ho mamella mocheso o phahameng, kahoo. u ke ke ua e sebelisa ka lebelo le potolohang.Bokhoni ba hau ba mochini le bona bo tla fokola.
Li-drill tsa Twist li loketse batho ba ikemetseng kapa basebelisi bao lisebelisoa tsa bona li seng morao haholo.
Likotoana tsa Spade.Likotoana tsena li shebahala joalo ka ha lebitso la tsona le bolela: moqomo o mong le o mong oa tšepe o felisoa ka lehare la kharafu.Kharafu e bataletse ka ntlha e bohale bohareng.Ntlha ena e sebetsa e le tataiso ho setsi sa lesoba le ho tataisa tataiso, empa boholo ba ho phunya ha e le hantle ho etsoa ke honing ho itšeha lehetleng la kharafu.
Ka lebaka la moralo o bonolo oa likharafu, ha e na bokhoni bo botle ba ho ntša chip.Ka nako e ts'oanang, ka lebaka la moralo oa sefofane oa mothapo o sehang, ho sebetsa hantle ha sekhahla sa spade ho fokola haholo.
Kahoo, bakeng sa ho nepahala, li-spade bits li molemo ho feta li-drill tsa twist.Empa ts'ebetso ea eona ea mochini e lokela ho ba e mpe ka ho fetesisa ho feta tsohle.
Li-twist drill li loketse batho ba ikemetseng ba sebelisang lisebelisoa tsa motlakase.
Brad Point Drills: Bakeng sa ho fihlela litlhoko tsa machining a lebelo le phahameng, ho ile ha qaptjoa "brad point drill bit".Brad point drill bit e kopanya melemo ea spade bit le twist drill.Ho na le ntlha ea ho phunya bohareng e le tataiso, 'me ho na le likarolo tse peli tse sehang mahlakoreng ka bobeli ho netefatsa bophara ba lesoba.'Me likotoana tsa "brad point drill" le tsona li na le li-spiral grooves ho eketsa bokhoni ba ho cheka.Moralo oa shank hape ke ho netefatsa hore o ka sebelisoa hamolemo ho mechini ea CNC.
Hape re ntlafalitse le ho tsebahatsa mefuta e fapaneng ea mefuta e fapaneng ea li-drill point hore bareki ba e sebelise maemong a fapaneng.Lisebelisoa tsa ho cheka tsa ZY li loketse machining a lebelo le tlase (1000-3000S/min).Li-drill tsa KJ-2 li loketse ho sebetsa ka lebelo le mahareng (2000-4000S/min) machining.Li-drill tsa KJ-1 li loketse ho sebetsa ka lebelo le phahameng (3000-6000S / min) machining.
Brad point drill bits ke khetho e ntle ka ho fetisisa bakeng sa bareki ba nang le mechini ea CNC.
Lisebelisoa tsa Countersink.Ho rekisoa likotoana tse entsoeng ka ho khetheha tse phunyang masoba bakeng sa likurufu tsa lehong.Li-drill tsa li-countersink li na le lintlha tse lumellanang le sebōpeho sa li-screw: masoba ao ba a phunyang a theola butle-butle bolelele ba "screw", 'me a holisa, a lumella lihlooho tsa li-screw hore li behoe ka lehong. mochini.
Forstner Bits.Likotoana tsena tse bohlale li phunya masoba ka botebo bo batlang bo sephara.Sebakeng sa ho ba le ntlha e moepa e lateloang ke li-angles tse sehiloeng, hanyane ea Forstner e tataisoa ke rim.Likanale tse ka har'a boro li hlakola lesoba la li-chips le lerōle.Sekoti se hlahang se na le botlaaseng bo batlang bo bataletse, bo sentsoeng feela ke lesoba la 1/32-inch bohareng moo ho qalisoang ha boro.
Li-bits tsa Forstner li batla li le theko e boima, 'me ha li hlokahale bakeng sa mesebetsi e mengata.Leha ho le joalo, li bohlokoa ho tse ling, joalo ka lihokelo tse fanyehoang tse tlamehang ho kengoa ka har'a lesoba le chitja le fetelang hanyane ka hanyane lemating.(Haeba u ne u ka sebelisa kharafu bakeng sa morero o tšoanang, ntlha ea eona e ka 'na ea phunyeletsa ka lehlakoreng le leng, e senya bokaholimo.) E loketse mochine oa mapolanka oa CNC.
