Izinhlobo zokubhoboza insimbi - yiziphi izinsimbi ongakhetha kuzo?

Isiqinisekiso somgodi owenziwe ngokunembile ensimbi i-drill ekhethwe kahle. Kuye ngempahla eluhlaza kanye nedivayisi yokubopha, izinhlobo ezahlukene zokunamathiselwe okusebenzayo zikhethwa kudivayisi yokusika. Yiziphi izinto zokuzivivinya zensimbi ezingahlukaniswa? Yini elungele lolu hlobo lomsebenzi?

Imishini emihle yensimbi - ungayibona kanjani? 

Ipharamitha ehlukanisa ama-drill achazwe kulezo ezihloselwe ezinye izinto i-angle yokuthambekela kwe-drill, i.e. isikhundla sokusika izindwani maqondana nomunye. Amathuluzi okusika insimbi anesivinini esikhulu anenani elingu-angular elingu-118 degrees. Ngenxa yakhe, ukusebenza kahle okuphezulu kokucubungula impahla kufinyelelwa.

Enye ipharamitha ebalulekile yizinto okwenziwa ngazo i-drill. Enye yazo insimbi ye-HSS okukhulunywe ngayo ngenhla, kanye nensimbi enokungcola kwe-cobalt ne-titanium. Ezinye izakhi zokusika zenziwe ngokuphelele nge-vanadium-molybdenum noma i-chrome-vanadium steel. Isihluthulelo sokukhetha ukunquma ubulukhuni bezinto ezibonakalayo kanye nobubanzi bomgodi okufanele wenziwe.

Ama-drill for metal - izici zezinhlobo zomuntu ngamunye 

Ngezansi kukhona abameleli abakhulu be-drill, okuphakathi kwezithandwa kakhulu emakethe. Yizinto ezingavuthiwe ezenziwe ngazo ezinquma ukuthi hlobo luni lwezinto ezingabhobolwa ngazo ngaphandle kokwesaba ukulimala.

Izinsimbi ze-titanium ezihlala isikhathi eside kakhulu 

Izintandokazi titanium drills ziwusizo ikakhulukazi lapho uphatha imithwalo esindayo. Ngenxa yokusetshenziswa kwe-titanium nitride ezihlanganiswe ngayo, ukumelana okuphezulu kakhulu nokuhuzuka kanye namazinga okushisa aphezulu kufinyelelwa. Lokhu kubenza bathandwe yizingcweti nezimboni lapho ukwethembeka kuyisihluthulelo sokusebenza kahle. Phakathi kwamamodeli atholakalayo ukuze asetshenziswe nsuku zonke, i-HSS yesandla sokudla yokubhoboza - TI uhlobo N iyagqama.

Izingcezu ze-Titanium zifanele ukusika izinsimbi (ngaphandle kwe-aluminium alloy ne-spring steel) nengilazi ye-acrylic, evame ukubizwa ngokuthi i-plexiglass. Abakhiqizi batusa ukusebenzisa ukupholisa lapho besebenza nge-drill, okuyinto, kuye ngokuthi impahla, ingaba amanzi (amapulasitiki) noma ama-emulsions kanye nama-lubricant (izinsimbi).

I-Cobalt Precision Drills 

ikhwalithi ephezulu izivivinyo ze-cobalt Zisetshenziswa, ikakhulukazi, lapho kwenziwa izimbobo ezinsimbi ezikwazi ukumelana nokushisa, ukumelana nokugqwala kanye nezinsimbi ezingenasici. Ngokungafani nokubhoboza i-titanium, i-engeli yeblade yokusika evame kakhulu ngamadigri ayi-135. Ngenxa yalokhu, asikho isidingo sokumba imbobo yokuqala ngaphambi kokusebenzisa imodeli echazwe.

Ukuba khona kokungcola kwe-cobalt kuholela eqinisweni lokuthi izesekeli zokusika zithola ukumelana nokushisa okukhulu kakhulu futhi zibonakala ngokukhuphuka kwempilo yesevisi uma kuqhathaniswa nensimbi ehlanzekile yejubane eliphezulu. Izakhiwo zokuzibekela maphakathi zisiza ukuqeda umcimbi wokuslayida i-drill ebusweni bento ecutshungulwayo. Izinsimbi ze-Titanium ne-cobalt eyenzelwe ukusebenza ngezinto eziqinile, ngakho-ke zivame ukukhethwa ochwepheshe.

Ukubhoboza okujwayelekile kwezinto ezithambile. 

Uhlobo oluhlukile lokuzibhoboza kwensimbi kokusetshenziswa kancane kochwepheshe izesekeli ze-HSS. Azikwazi ukumelana namazinga okushisa okusebenza afinyelela ku-400 degrees Celsius. Kubantu abasika izinsimbi ngezikhathi ezithile noma basebenzise kuphela imishini yokulungisa ikhaya, lezi yizesekeli ezifanele. I-point angle yabo yi-118 degrees, okusho ukuthi ukuze kuzuzwe izilinganiso ezifanele kanye nokugxilisa imbobo, kufanelekile ukuyibhoboza ngethuluzi elincane.

I-HSS yensimbi enesivinini esiphezulu ngaphandle kwengxube yezinye izinto zokusetshenziswa isiza ukwehlisa intengo yomkhiqizo wokugcina. Ngakho-ke, isifiso sokuthenga ama-drill bits amahle ensimbi ngaphandle kokuchitha amanani abalulekile, kufanelekile ukucabangela lezi zinhlobo zezesekeli.

Ezinye izinhlobo zokubhoboza insimbi 

Izinhlobo zokuprakthiza ezidumile zifaka phakathi ama-drill anesibambo sokukhweza esiphendukile. Lezi yizesekeli ze-HSS steel screw ezingasetshenziswa kuma-drill chucks amancane. Zinhle kakhulu ekwenzeni izimbobo ezinkulu zensimbi ngamathuluzi okusika ajwayelekile.

Enye imodeli i-conical drill yensimbi. Ngezinye izikhathi ibizwa nangokuthi isihlahla sikaKhisimusi, esinezigaba noma esinezigaba eziningi. I-nomenclature ivela kusimo sayo sesici, esivumela ukuthi kwenziwe izimbobo ezinembile, ikakhulukazi eshidini lensimbi namapayipi. Ngenxa yezakhiwo zokuzicabangela ze-drill, isetshenziswa ngaphandle kokubhoboza kuqala impahla. Ukuba khona kwe-blade ephansi nama-blade amabili asemaceleni kuqinisekisa ukulungiselelwa okuzinzile kokubhoboza ngisho nalapho kucutshungulwa amapayipi ensimbi amise okweqanda.

Ama-countersink alungele ukuvuselela izimbobo ezinsimbini eziqinile njengensimbi, insimbi ekhonjiwe nepulasitiki. Ngenxa yokusikwa kwezinto zokusetshenziswa eziqinile, ngokuvamile zenziwa ngensimbi ye-HSS-Ti. Zimelana kakhulu namazinga okushisa aphezulu kanye nokuhuzuka. Zigaya kahle kakhulu futhi zijule izimbobo ezenziwe ngaphambilini.

Indlela yokufaka ama-drill ensimbi 

Yini drills for metal ukhethe idivayisi ethile? Ngokuyisisekelo, kunezinhlobo ezi-4 zokunamathiselwe kwethuluzi kudivayisi. Lawa ngamapeni:

• Morse,
• ukukhweza okusheshayo,
• I-SDS-MAX,
• I-SDS-PLUS.

I-Morse taper chuck iyingxenye yokubhoboza nama-reamer afakwe kumathuluzi omshini. Indlela yokuqinisa ukufakwa okunjalo kumadivayisi inomthelela ekudlulisweni kwezikhathi ezinkulu ngosizo lwesibambo esifakwe ngokukhethekile ngendlela ye-shaft.

Ngenkathi bhola izingcezu zensimbi kumathuluzi ane-chuck yokuzikhiya, asesimweni senduku enobubanzi obufanayo. Ziyimishini yokuzivocavoca esetshenziswa kakhulu ekusetshenzisweni kwezinhloso ezijwayelekile.

Isimo sihlukile ngombambi we-SDS. Zisetshenziswa kakhulu kwizando ezijikelezayo futhi zisetshenziselwa ukubamba izinsimbi zokubhola eziklanywe ngokukhethekile. I-SDS-PLUS isetshenziswa ezinhlelweni ezingafuneki kangako nezingasindi, kuyilapho i-SDS-MAX ingakwazi ukuthwala imishini emikhulu kuno-18mm.

Uma ufuna ama-drill bits ensimbi, kufanelekile ukuphendula umbuzo wokuthi isicelo sabo sizoba yini. Uma wenza izimbobo ngama-diameter aphindaphindiwe futhi azikho eziningi kakhulu, ungenza isethi enjalo ngokwakho. Uma kungenjalo izofika kahle isethi yokubhoboza izingcezu zensimbi
