Chinhu chekutanga kutaura nezvazvo chiitiko chemuviri chetitanium alloy process. Kunyangwe simba rekucheka retitanium alloy rakangokwirira zvishoma pane iro resimbi ine kuoma kwakafanana, chiitiko chemuviri chekugadzirisa titanium alloy yakanyanya kuomarara kupfuura yekugadzira simbi, izvo zvinoita kuti kuoma kwekugadzirisa titanium alloy kukwira.
Iyo yekupisa conductivity yeakawanda titanium alloys yakadzikira, chete 1/7 yesimbi uye 1/16 yealuminium. Nokudaro, kupisa kunogadzirwa mukugadzira titanium alloys hakuzokurumidza kuendeswa kune workpiece kana kutorwa nemachipisi, asi kuchaungana munzvimbo yekucheka, uye tembiricha inogadzirwa inogona kunge yakakwira se1 000 ° C kana kupfuura. , iyo ichaita kuti kuchekwa kwechigadziro chinokurumidza kupfeka, chip uye kuputika. Kuumbwa kwekuvakwa-kumucheto, kutaridzika kwekukurumidza kwepende yakasakara, iyo inokonzera kupisa kwakawanda munzvimbo yekucheka, kuwedzera kupfupisa hupenyu hwechishandiso.
Kupisa kwepamusoro kunogadzirwa panguva yekucheka kunoparadzawo kutendeseka kwepamusoro kwetitanium alloy zvikamu, zvichiita kuti kuderera kwejometri yakarurama yezvikamu uye basa rinoomesa chiitiko chinoderedza zvakanyanya simba ravo rekuneta.
Iyo elasticity yetitanium alloys inogona kubatsira pakuita kwezvikamu, asi panguva yekucheka, iyo elastic deformation yeworkpiece ndicho chikonzero chakakosha chekudengenyeka. Kudzvanya kwekucheka kunoita kuti "elastic" workpiece iende kure nechombo uye kuputika kuitira kuti kukweshana pakati pechishandiso uye workpiece yakakura kupfuura yekucheka chiito. Iyo friction process inoburitsawo kupisa, zvichiwedzera dambudziko rekushata kwekupisa kwetitanium alloys.
Dambudziko iri rinotonyanya kuipa kana uchigadzira mativi akatetepa-ane madziro kana mhete anoremara nyore. Harisi basa riri nyore kugadzira titanium alloy dzakatetepa-madziro zvikamu kune zvinotarisirwa dimensional kurongeka. Nekuti kana iyo workpiece zvinhu zvinosundirwa kure nechishandiso, iyo yemuno deformation yemadziro akaonda yakapfuura elastic renji uye deformation yepurasitiki inoitika, uye kusimba kwezvinhu uye kuoma kwekucheka kunowedzera zvakanyanya. Panguva ino, machining pane yakambotemerwa kucheka kumhanya inova yakanyanya kukwirira, zvichizokonzera kupinza kwechishandiso kupfeka. Zvinogona kutaurwa kuti "kupisa" ndiyo "mudzi chikonzero" chinoita kuti zviome kugadzira titanium alloys.
Semutungamiri muindasitiri yekucheka maturusi, Sandvik Coromant akanyatso nyora maitiro ekuziva magadzirirwo etitanium alloys uye akagovaniswa neindasitiri yese. Sandvik Coromant akataura kuti pahwaro hwekunzwisisa magadzirirwo etitanium alloys uye nekuwedzera ruzivo rwakapfuura, iyo huru maitiro ekuziva magadzirirwo etitanium alloys ndeaya anotevera:
(1) Inopinza ine yakanaka geometry inoshandiswa kuderedza kutema simba, kucheka kupisa uye workpiece deformation.
(2) Chengetedza chikafu chinogara chiripo kuti udzivise kuomarara kwechishandiso, chishandiso chinofanira kugara chiri munzvimbo yekudya panguva yekucheka, uye radial yekucheka huwandu ae inofanira kunge iri 30% yeradius panguva yekugaya.
(3) High-pressure uye yakakura-inoyerera yekucheka mvura inoshandiswa kuve nechokwadi chekudzikama kwekupisa kweiyo machining process uye kudzivirira workpiece kuderera kwepamusoro uye kukuvara kwechishandiso nekuda kwekupisa kwakanyanya.
(4) Chengetedza blade mupendero wakapinza, maturusi asina kujeka ndiwo anokonzera kupisa-up uye kupfeka, izvo zvinogona kutungamirira nyore kutadza kwechishandiso.
(5) Machining mune yakapfava mamiriro etitanium alloy zvakanyanya sezvinobvira, nekuti zvinhu zvinova zvakanyanya kuoma kumichina mushure mekuoma, uye kupisa kurapwa kunowedzera kusimba kwechinhu uye kunowedzera kupfeka kwekuisa.
(6) Shandisa mhino yakakura kana chamfer kuti ucheke mukati, uye isa mativi akawanda ekucheka sezvinobvira mukucheka. Izvi zvinoderedza simba rekucheka uye kupisa panzvimbo yega yega uye kudzivirira kuparara kwenzvimbo. Pakugaya titanium alloys, pakati pematanho ekucheka, kumhanya kwekucheka kune simba guru pane chishandiso hupenyu vc, inoteverwa neiyo radial yekucheka huwandu (milling kudzika) ae.
