Kutheni izinto zeStainless Steel kunzima ukusetyenzwa?

Intsimbi estainless,  ekuqaleni yayibizwa ngokuba yintsimbi erustless, yiyo nayiphi na kwiqela lealloys eneferrous enobuncinane obumalunga ne-11% yechromium, into eyenzeka ethintela i-iron ekurusini kwaye ikwabonelela nangeempawu ezikwaziyo ukumelana nobushushu.

Xa kuthelekiswa neentsimbi "ezithambileyo" ezifana ne-aluminiyam, isinyithi esingenasici sinzima kakhulu ukwenza umatshini. Oku kungenxa yokuba intsimbi estainless yintsimbi yealloyi enamandla aphezulu kunye neplastiki elungileyo. Ngexesha lenkqubo yomatshini, izinto ziya kuba nzima kwaye zivelise ubushushu obuninzi. Oku kukhokelela ekunxibeni kwesixhobo sokusika ngokukhawuleza. Apha shwankathela izizathu ezi-6 eziphambili:

1. Amandla aphezulu obushushu kunye nokuthambekela kokuqina komsebenzi

Xa kuthelekiswa nentsimbi eqhelekileyo, insimbi engenasici inamandla aphakathi kunye nokuqina. Nangona kunjalo, iqulethe inani elikhulu lezinto ezifana ne-Cr, i-Ni, kunye ne-Mn, kwaye ine-plasticity enhle kunye nokuqina, amandla okushisa aphezulu, kunye nokuthambekela kobunzima bomsebenzi ophezulu obangela ukuba umthwalo wokusika. Ukongezelela, kwi-austenitic insimbi engenasici ngexesha lokusika, enye i-carbide iyancipha ngaphakathi, eyandisa umphumo wokukrazula kwi-cutter.

2.Kufuneka amandla amakhulu okusika

Insimbi engenasici ine-deformation enkulu yeplastiki ngexesha lokusika, ngokukodwa i-austenitic stainless steel (i-elongation idlula amaxesha angama-1.5 kwintsimbi ye-45), eyandisa amandla okusika.

I-3.Chip kunye nesixhobo sokudibanisa into eqhelekileyo

Kulula ukwenza i-edge eyakhiweyo ngexesha lokusika, elichaphazela ubuninzi bomhlaba owenziwe ngomatshini kwaye ngokulula kubangela ukuba umphezulu wesixhobo ukhuphe.

4. I-chip ilula ukugoba kunye nokuphuka

Kwizisiki ezivaliweyo nezivaliweyo, ukuvala itshiphu kulula ukwenzeka, okukhokelela ekwandeni koburhabaxa bomphezulu kunye nokutshitshwa kwesixhobo.

Isazobe.2. Ubume be-chip obufanelekileyo bentsimbi engatyiwayo

5. I-coefficient enkulu yokwandiswa komgca

Kumalunga nesiqingatha esinye kunye nesiqingatha se-coefficient yokwandisa i-carbon steel. Ngaphantsi kwesenzo sokusika ukushisa, i-workpiece ixhomekeke kwi-thermal deformation kwaye ichaphazela ukuchaneka kwe-dimensional.

6. Incinci i-thermal conductivity

Ngokuqhelekileyo, malunga ne-1/4 ~ 1/2 ye-thermal conductivity ye-carbon steel medium. Ubushushu bokusika buphezulu kwaye isixhobo sinxiba ngokukhawuleza.

Indlela yokwenza iStainless steel?

Ngokusekwe kuqheliselo lwethu kunye namava, sikholelwa ukuba ezi zikhokelo zilandelayo kufuneka zilandelwe ukuze machining imathiriyeli steel stainless:

1.Unyango lobushushu phambi komatshini, Inkqubo yonyango lobushushu inokutshintsha ubulukhuni bentsimbi engatyiwayo, yenze kube lula ukumatshini.

2.Ukuthambisa okugqwesileyo, Ulwelo lokuthambisa olupholileyo lunokuthatha ubushushu obuninzi kwaye luthambise umphezulu wemveliso ngaxeshanye. Ngokuqhelekileyo sisebenzisa i-lubricant edibeneyo eyenziwe yi-nitrogen tetrafluoride kunye ne-oyile ye-injini. Ukuziqhelanisa kubonise ukuba le lubricant ifaneleke kakhulu ekwenzeni iindawo zentsimbi ezingenasici ezinomgangatho ogudileyo.

3.Sebenzisa izixhobo zokusika ezikumgangatho ophezulu ukufumana indawo egudileyo kunye nokunyamezelana okuncinci ngelixa unciphisa ixesha lokutshintsha isixhobo.

4.Isantya esisezantsi sokusika. Ukukhetha isantya esisezantsi sokusika kunokunciphisa ukuveliswa kobushushu kunye nokuququzelela ukuphulwa kwe-chip.

Ukuqukumbela

Lilonke, insimbi engenasici yenye yezona zinto zinzima kumatshini. Ukuba ivenkile yomatshini iyakwazi ukwenza umatshini we-aluminiyam, ubhedu, kunye nentsimbi yekhabhoni kakuhle, oku akuthethi ukuba banako umatshini wentsimbi engatyiwa kakuhle kakhulu.
