iindaba

Kwinkqubo yokuvelisa amacandelo edayimane, iingxaki ezahlukeneyo zingenzeka.Kukho iingxaki ezibangelwa kukusebenza ngendlela engafanelekanga ngexesha lenkqubo yokuvelisa, kunye nezizathu ezahlukeneyo ezibonakala kwinkqubo yomxube wefomula kunye nokudityaniswa kwe-binder.Uninzi lwezi ngxaki zichaphazela ukusetyenziswa kwecandelo.Ngaphantsi kweemeko ezinjalo, icandelo ledayimane alinakusetyenziswa okanye lingasebenzi kakuhle, lichaphazela ukusebenza kakuhle kwemveliso yamatye kunye nokunyusa iindleko zokuvelisa.Ezi meko zilandelayo ziqhelekile kwiingxaki zomgangatho kunye namacandelo edayimani:

Iinkcukacha zecandelo ezingalunganga

Nangona icandelo ledayimani lingumxube wealloyi yesinyithi kunye nedayimane edityaniswe ngumbumba osisigxina, imveliso yokugqibela igqityezelwa ngokucinezela okubandayo kunye nokucinezela okutshisayo, kwaye izinto eziphathekayo zizinzileyo, kodwa ngenxa yoxinzelelo olungonelanga kunye nobushushu be-sintering ngexesha ukusetyenzwa kwecandelo, okanye Ngexesha lenkqubo ye-sintering, ubushushu kunye noxinzelelo lwe-insulation kunye noxinzelelo alwanelanga okanye luphezulu kakhulu, oluya kubangela amandla angalinganiyo kwicandelo, ngoko ngokwemvelo kuya kuba nezizathu zokwahlukana kubukhulu becala. icandelo.Ukubonakaliswa okubonakalayo kukuphakama kwecandelo kunye nendawo apho uxinzelelo alwanele.Kuya kuba phezulu, kwaye uxinzelelo luya kuba luphantsi kakhulu.Ngoko ke, kwinkqubo yokuvelisa, kuyimfuneko kakhulu ukuzinzisa uxinzelelo kunye nobushushu obufanayo.Ngokuqinisekileyo, kwinkqubo yokulayishwa kwangaphambili, ucinezelo olubandayo lwecandelo kufuneka kwakhona lilinganiswe;kwakhona qaphela ukuba ungathathi isikhunta esingalunganga kwaye ubangele ukuba icandelo lichithwe.Vela.Ubungakanani bedayimane yedayimane ayihambelani neemfuno, ukuxinana akwanelanga, ukuqina akuhambelani neemfuno, kukho i-debris kwi-transition layer, kwaye amandla e-bit awanele.

 

 

 

Ukuxinana okunganeleyo, ibhondi yecandelo iyathamba

Kwinkqubo yokusika ilitye nge-dense kunye ne-soft bit, i-bit fracture iya kwenzeka.I-fracture ihlulwe ibe yi-fracture inxalenye kunye ne-fracture jikelele.Nokuba yeyiphi na uhlobo lokwaphuka, intwana enjalo ayinakuphinda isetyenziswe.Ngokuqinisekileyo, ukuphuka kwecandelo ngumda.Xa usika ilitye, icandelo elinobuninzi obunganeleyo aliyi kukwazi ukunqumla ngenxa yobunzima obunganeleyo be-Mohs, okanye icandelo liya kusetyenziswa ngokukhawuleza.Ngokubanzi, ukuxinana kwecandelo kufuneka kuqinisekiswe.
Imeko enjalo ngokuqhelekileyo ibangelwa ukushisa kwe-sintering, ukubamba ixesha, uxinzelelo olunganeleyo, ukhetho olungalunganga lwezinto ze-ejenti yokubambisana, umxholo wedayimane ophezulu wecandelo, njl. Kuqheleke kakhulu ukwenzeka, kwaye kuya kubonakala kwiifomyula ezindala.Isizathu esiqhelekileyo kukusebenza ngokungafanelekanga kwabasebenzi, kwaye ukuba yifomula entsha, uninzi lwezizathu zibangelwa kukungaqondi komyili wefomula.Umyili kufuneka alungise ngcono ifomyula yecandelo kwaye adibanise ubushushu.Kunye noxinzelelo, ukunika iqondo lobushushu sintering esengqiqweni ngakumbi kunye noxinzelelo.

Ukusebenza okuphantsi

Isizathu esona sizathu sokuba icandelo ledayimane lingakwazi ukusika ilitye kukuba amandla awanele, kwaye amandla awanele ngenxa yezizathu ezihlanu ezilandelayo:

1: Idayimani ayanelanga okanye idayimani ekhethiweyo ikumgangatho ophantsi;
I-2: Ukungcola, okufana neengqungquthela zegraphite, uthuli, njl., Zixutywe kwicandelo ngexesha lokuxuba kunye nokulayisha, ngakumbi ngexesha lokuxuba, ukuxuba okungafaniyo kunokubangela le meko;
I-3: Idayimane igqithise i-carbonized kwaye ubushushu buphezulu kakhulu, nto leyo ebangela ukuba i-diamond carbonization enzulu.Ngethuba lenkqubo yokusika, iinqununu zedayimane zilula ukuwa;
I-4: Uyilo lwefomyula yecandelo alunangqiqo, okanye inkqubo ye-sintering ayinangqiqo, okubangelwa amandla aphantsi omgangatho wokusebenza kunye nomgca wenguqu (okanye uluhlu olusebenzayo kunye noluhlu olungasebenziyo aludibanisi ngokuqinileyo).Ngokuqhelekileyo, le meko idla ngokuvela kwiifomula ezintsha;
5: Isixhobo sokudibanisa isixhobo sithambile kakhulu okanye siqine kakhulu, okukhokelela ekusetyenzisweni okungafaniyo kwedayimani kunye nesibophelelo sesinyithi, okukhokelela ekubeni isibophelelo sematrix yedayimani singakwazi ukubamba umgubo wedayimani.

Icandelo liyawa

Kukho izizathu ezininzi zokuba intloko yokusika iwe, njengokungcola okuninzi, ubushushu obuphezulu okanye obuphantsi kakhulu, ukugcinwa kobushushu obufutshane kunye nexesha lokubamba uxinzelelo, umlinganiselo wefomula engafanelekanga, umaleko we-welding ongekho ngqiqweni, umaleko ohlukeneyo wokusebenza kunye nefomula engasebenziyo. okukhokelela kwi-coefficient yokwandisa i-thermal ye-Different ezimbini, xa icandelo lipholile, uxinzelelo lwe-shrinkage lwenzeka kwinqanaba lokusebenza kunye noxhumo olungasebenziyo, oluya kuthi ekugqibeleni lunciphise amandla ecandelo, kwaye ekugqibeleni lubangele ukuba icandelo liwe.Ezi zizathu zizizathu ezenza ukuba i-diamond bit ziwe okanye i-saw blade ilahlekelwe ngamazinyo.Ukuyicombulula le ngxaki, kufuneka siqale siqinisekise ukuba umgubo uvuthululwe ngokulinganayo kwaye awunakungcola, kwaye emva koko utshatise uxinzelelo olufanelekileyo, ubushushu kunye nexesha lokugcinwa kobushushu, kwaye sizame ukuqinisekisa ukuba i-coefficient yokwandiswa kwe-thermal yomaleko osebenzayo kunye ne-non -working layer zisondelelene.
Ngethuba lokucutshungulwa kwamacandelo edayimane, ezinye iingxaki zingavela, ezifana nokusetyenziswa ngokugqithiseleyo, i-jamming, i-eccentric wear, njl. Iingxaki ezininzi azikho nje ingxaki yecandelo, kodwa inokunxulumana nomatshini, uhlobo lwamatye, njl.
