Ukukhetha isixhobo sokusika

Ukukhetha aumsiki wokugayaasingomsebenzi olula. Kukho izinto ezininzi eziguquguqukayo, iimbono kunye nelore ekufuneka iqwalaselwe, kodwa ngokuyinyani i-machinist izama ukukhetha isixhobo esiya kunqumla izinto ezibonakalayo kwiinkcukacha ezifunekayo ngexabiso elincinci. Iindleko zomsebenzi yindibaniselwano yexabiso lesixhobo, ixesha elithathwa yiumatshini wokugaya,kunye nexesha elithathwa ngumashini. Ngokuqhelekileyo, kwimisebenzi yenani elikhulu lamacandelo, kunye neentsuku zexesha lomatshini, ixabiso lesixhobo liphantsi kweendleko ezintathu.

• Izinto:Abasiki bentsimbi yesantya esiphezulu (i-HSS) ngabona basiki bexabiso elincinci kwaye baphila ixesha elifutshane. Iintsimbi ezinesantya esiphezulu esineCobalt ngokubanzi zinokuqhutywa nge-10% ngokukhawuleza kunentsimbi eqhelekileyo yesantya esiphezulu. Izixhobo ze-carbide ezifakwe isamente zibiza kakhulu kunentsimbi, kodwa zihlala ixesha elide, kwaye zinokuqhutywa ngokukhawuleza, ngoko ke bonakalisa ukonga ngakumbi ekuhambeni kwexesha.izixhobo zeHSSzanele ngokugqibeleleyo kwizicelo ezininzi. Ukuqhubela phambili ukusuka kwi-HSS eqhelekileyo ukuya kwi-cobalt HSS ukuya kwi-carbide kunokubonwa njengento elunge kakhulu, nokuba ngcono, kwaye ingcono. Ukusebenzisa i-spindles enesantya esiphezulu kunokuthintela ukusetyenziswa kwe-HSS ngokupheleleyo.
• Ububanzi:Izixhobo ezikhulu zinokususa izinto ngokukhawuleza kunezincinci, ngoko ke eyona mveliso inkulu inokungena emsebenzini idla ngokukhethwa. Xa ukugaya i-contour yangaphakathi, okanye i-concave yangaphandle, i-diameter inqunyelwe ubukhulu bee-curves zangaphakathi. Iradiyasi yeumsikikufuneka ibe ngaphantsi okanye ilingane neradiyasi yeyona arc incinci.
• IiFlute:Iifleyiti ezingakumbi zivumela ireyithi yokutya ephezulu, kuba kukho imathiriyeli encinci esusiweyo ngefluti nganye. Kodwa ngenxa yokuba i-diameter engundoqo iyanda, kukho indawo encinci ye-swarf, ngoko ke kufuneka kukhethwe ibhalansi.
• Ukwaleka:Iingubo, ezifana ne-titanium nitride, nazo zonyusa iindleko zokuqala kodwa zinciphisa ukuguga kunye nokwandisa ubomi besixhobo.TiAlN ukutyabekakunciphisa ukuncamathelwa kwe-aluminiyam kwisixhobo, ukunciphisa kwaye ngamanye amaxesha ukuphelisa imfuno yokuthambisa.
• I-engile ye-Helix:Ii-engile ze-helix eziphezulu zezona zilungileyo kwiintsimbi ezithambileyo, kunye nee-engile ze-helix eziphantsi kwiintsimbi ezinzima okanye ezomeleleyo.
