Umngxunya wokuvula umngxuma, okwaziwa ngokuba ziisarha zomngxunya okanye umngxunya wesarha, kubhekiswa kwisarha ekhethekileyo yokujikeleza umngxunya osetyhula kwishishini langoku okanye kubunjineli. Kulula ukusebenza, kulula ukuyiphatha, ikhuselekile kwaye isetyenziswa ngokubanzi. Kukulungele ukusika umngxuma ojikelezayo, umngxunya wesikwere, umngxuma ongunxantathu, umgca othe tye kunye negophe kuwo nawuphi na umphezulu ogobileyo wobhedu, isinyithi, intsimbi engenasici, iplexiglass kunye namanye amacwecwe xa kufakwe kumbhobho oqhelekileyo wombane.

Ngokobungakanani obahlukeneyo besangqa, abapheki banezinto ezahlukeneyo kunye neenkcukacha. Kwangaxeshanye, ngokobunzulu bemingxunya, yahlulahlulwe yohlobo oluqhelekileyo kunye nohlobo lomthwalo onzulu. Zifakwe kwisandla sombane, i-drill drill, i-rocker drill kunye nezinye izixhobo zombane.

Kukho iintlobo ezimbini eziqhelekileyo:ububanzi obuqingqiweyo kunye nobubanzi obuguqukayo (uhlobo lwenqwelomoya). Indawo evulekileyo yokuvula umngxuma ihlala isetyenziselwa ukuhombisa ngaphakathi nangaphandle.

Ububanzi obujikeleziweyo bokuvula umngxuma, kukho uhlobo oluqhelekileyo, uhlobo lwefuthe, uhlobo olupholileyo ngamanzi, oluhlobo olupholileyo lwamanzi oluqhelekileyo lusetyenziselwa ukuvulwa kodonga, ngokusebenza okuphezulu kunye nokuvula okuhle.

 

Ngokoluhlu lwezixhobo:Umngxunya ovulekileyo womngxuma wesinyithi Izinto ezahlukeneyo zisetyenziselwa ukusika izinto ezahlukeneyo. Eyona nto isetyenziswa kakhulu sisarimetallic saw. I-carbide yesamente iyacetyiswa ngezinto zentsimbi ezilukhuni, kwaye idayimani iyacetyiswa ngeglasi, ifayibha yekhabhoni, iiseramikhi kunye nezinye izinto ezibuthathaka.

 

Izixhobo zokuvula umngxunya ikakhulu zibandakanya:isiphatho senkxaso, intwasahlobo, isuntswana lokumba, njl njl. isibambo senkxaso yeyamalungu ngokubanzi. Umngxunya wesarha enobubanzi obuhlukeneyo bomngxunya uxhotyiswe ngemilinganiselo emibini yesiphatho senkxaso. Ububanzi bomngxuma ophakathi kwe-14 ne-32 mm yinkcazo enye, kwaye ububanzi bomngxuma ongaphezulu kwe-32 mm yinkcazo enye.

Umngxuma ovulekileyo onobubanzi obuhlukeneyo bomngxunya uxhotyiswe ngemilinganiselo emibini yesiphatho senkxaso. Ububanzi bomngxuma ophakathi kwe-14 ne-32 mm yinkcazo enye, kwaye ububanzi bomngxuma ongaphezulu kwe-32 mm yinkcazo enye.

Isantya esiphezulu sentsimbi luhlobo lwesixhobo sesinyithi esinobulukhuni obuphezulu, ukuxhathisa okuphezulu kunye nokuchasana nobushushu obuphezulu. Isantya esiphezulu sentsimbi ubukhulu becala sisetyenziselwa ukuvelisa izixhobo ezintsonkothileyo ezinqamlezileyo kunye nokusika izixhobo zokusika zesinyithi, kunye nokushisa okuphezulu kunye nokubandayo okubandayo kusweleke ngenxa yenkqubo yokusebenza okuhle kunye nokudityaniswa okuhle kwamandla kunye nobukhali.

Isantya esiphakamileyo sesinyithi luhlobo lwesixhobo sokuvula esenziwe ngesantya esiphezulu sentsimbi, esetyenziselwa ikakhulu ukuvula imingxunya kwiipleyiti zesinyithi okanye imibhobho. Ingasetyenziselwa umngxuma wokubekwa kwindawo embindini ngaphambi kokuvulwa komngxunya, emva koko umngxunya wentsimbi obonayo ukuvula ububanzi bomngxunya ofunekayo.

Zininzi iindidi zemingxunya evulekileyo yokuvula imingxunya. Ngoku imakethi yahlulwe (ngesiqhelo) i-sheet yentsimbi ebhityileyo, (uhlobo olusebenzayo) intsimbi ekhethekileyo evulekileyo engenazingcingo. (ibanga eliphakathi) intsimbi ekhethekileyo evulekileyo engenasici. (Uhlobo oluphezulu) uhlobo olukhethekileyo oluvulekileyo lwentsimbi (ubukhulu beplate yensimbi bunokufikelela ngaphezulu kwe-2cm).

Okwesibini: i-bimetallic hole opener isetyenziselwa ukuvula i-sheet yentsimbi, iplanga kunye neplastiki.

Okwesithathu, ukusetyenziswa kwesantya esiphezulu sentsimbi yokuvula umngxuma wokuvula kunye nealloy tapper ziyafana. Amanqaku: isiqhelo, ibanga eliphakathi, inqanaba eliphezulu, ukugaya ngokupheleleyo, inqanaba loshishino.

Okokugqibela, i-alloy tapper ilungele ipleyiti yesinyithi kunye nesantya esiphezulu somatshini wokuthinta intsimbi kufanelekile kumbhobho wentsimbi.

 

Isinyithi esikhawulezayo esingu-6542

Iimpawu: Umxholo vanadium ephantsi (1%) kunye nomxholo ayibe eliphezulu (8%). I-Cobalt kunye ne-Du zinokwenza ukuba iikhabhoni zonyibilike ngakumbi kwi-matrix ngexesha lokucima kunye nokufudumeza, kwaye zisebenzise ubunzima bematrix obuphezulu ukuphucula ukuxhathisa.

Ukuqina: olu hlobo lwesantya esiphezulu sentsimbi lunobulukhuni obulungileyo, ukomelela kobushushu, ukunxiba ukuxhathisa kunye nokukwazi ukusila. Ubulukhuni bonyango lobushushu bunokufikelela kuma-67-70hrc, kodwa kusetyenziswa iindlela ezizodwa zonyango lobushushu ukufumana ubunzima be-67-68hrc, obuphucula ukusebenza kokusika (ngakumbi ukusika okungaphakathi) kwaye kuphucule ukuqina kwempembelelo.

Isicelo: i-cobalt yesantya esiphezulu sentsimbi inokwenziwa kwiintlobo ezahlukeneyo zezixhobo zokusika, ezinokusetyenziselwa ukunciphisa ubunzima kwizinto zomatshini. Ngenxa yokusebenza kokugaya okuhle, inokwenziwa izixhobo zokusika ezinzima, ezisetyenziswa kakhulu kwihlabathi. Nangona kunjalo, ngenxa yokunqongophala kwezixhobo ze-cobalt e-China, ixabiso le-cobalt yesantya esiphezulu sentsimbi liphezulu kakhulu, elimalunga namaxesha ama-5-8 aloo ngesinyithi esiqhelekileyo esikhawulezayo.

Ukhuselo lokusingqongileyo: izinto ukhuselo lokusingqongileyo, akukho ungcoliseko.
