Chishandiso chimwe chezvakakosha zvikamu mumachining muchina maturusi.Nekuvandudzwa kwesainzi uye tekinoroji, chishandiso chachinja kubva kune yekutanga alloy turusi kuenda kune inonyanya kushandiswa yakavharidzirwa chishandiso.Kugaya uye kupfekedzwazve kwecemented carbide uye high-speed steel maturusi ndiwo maitiro akajairika panguva ino.Kunyangwe mutengo wezvishandiso zvekugaya kana kudzorerazve chikamu chidiki chemutengo wekugadzira wezvishandiso zvitsva, unogona kurebesa hupenyu hwematurusi uye kuderedza mutengo wekugadzira.Regrinding process ndiyo yakajairika nzira yekurapa yematurusi akakosha kana maturusi anodhura.Zvishandiso zvinogona kudzokororwa kana kudzokororwa zvinosanganisira zvibooro, zvicherwa zvekugayo, hobho nematurusi ekuumba.
Tool regrinding
Muchigadziro chekugadzira chibooreso kana chigayo chekucheka, zvakakosha kugaya chidimbu chekucheka kuti ubvise chifukidzo chepakutanga, saka gumbo rekukuya rinoshandiswa rinofanira kuva nekuoma kwakakwana.Iko-pre-processing yekucheka kwekucheka nekudzorera kunokosha zvikuru.Hazvisi izvo chete zvakakosha kuti ive nechokwadi chekuti geometric chimiro chepakutanga chekucheka chepakutanga chinogona kuchengetwa zvachose uye chakanyatsochengetwa mushure mekugadzirisa chigadziro, asi zvinodawo kuti PVD yakavharidzirwa chimbo inofanira kuva "yakachengeteka" yekudzorerazve.Nokudaro, zvinodikanwa kuti udzivise nzira isina kufanira yekukuya (yakadai sekucheka kwakashata kana kuomeswa kwakaoma, uko nzvimbo yechishandiso ichikanganiswa nekuda kwekupisa kwepamusoro).
Kubviswa kwekuvhara
Chishandiso chisati chadzokororwa, zvese zvekutanga zvekupfeka zvinogona kubviswa nemakemikari nzira.Kemikari yekubvisa nzira inowanzoshandiswa kune yakaoma maturusi (senge hobs uye mabroaches), kana maturusi ane akawanda recoating uye maturusi ane matambudziko anokonzerwa necoating ukobvu.Iyo nzira yekubvisa kemikari yekuputira kazhinji inongogumira kune yakakwira-kumhanya simbi maturusi, nekuti iyi nzira ichakuvadza simende carbide substrate: iyo nzira yekubvisa kemikari yejasi ichasefa cobalt kubva kune simende carbide substrate, zvichikonzera porosity yepasi. substrate, kuumbwa kwe pores uye kuoma kwekugadzirisa zvakare.
"Chemical kubvisa nzira inosarudzwa pakubvisa ngura yezvipfeko zvakaoma pasimbi yakakwirira-speed."Nekuda kwekuti iyo cemented carbide matrix ine makemikari anoumba akafanana neaya ari mujasi, iyo kemikari yekubvisa solvent inonyanya kukuvadza simende carbide matrix pane yakakwirira-kumhanya simbi matrix.
Pamusoro pezvo, kune mamwe maitiro emakemikari ane patent akakodzera kubvisa PVD coating.Mune idzi nzira dzemakemikari, pane kashoma kemikari kuita pakati peyekubvisa coating solution necemented carbide matrix, asi nzira idzi hadzisati dzashandiswa zvakanyanya parizvino.Mukuwedzera, kune dzimwe nzira dzekuchenesa kuvhara, zvakadai se laser processing, abrasive blasting, etc. Kemikari kubvisa nzira ndiyo nzira yakajairika, nokuti inogona kupa kufanana kwakanaka kwekubviswa kwepamusoro.
Parizvino, iyo yakajairwa yekudzoreredza maitiro ndeyekubvisa iyo yepakutanga yekupfekedza chishandiso kuburikidza nekuita regrilling.
Economy yekudzokorora
Anonyanya kushandiswa maturusi machira ndeyeTiN, TiC uye TiAlN.Mamwe superhard nitrogen/carbide coatings akaiswawo, asi haana kunyanya kuwanda.PVD diamond yakavharwa maturusi anogona zvakare kudzoreredzwa uye kudzokororwa.Munguva yekudzoreredza maitiro, chishandiso "chinodzivirirwa" kudzivirira kukanganisa kune yakakosha nzvimbo.
Izvi zvinowanzoitika: mushure mekutenga maturusi asina kuvharwa, vashandisi vanogona kuapfekedza paanenge achida kugadziridzwa, kana kuisa machira akasiyana pazvishandiso zvitsva kana maturusi ereground.
Kuganhurirwa kwekudzokorora
Sezvinongoita chishandiso chinogona kudzoserwa pasi kakawanda, kuchekwa kwechishandiso kunogona zvakare kuvharwa kakawanda.Chinokosha chekuvandudza kushanda kwechishandiso ndechekuwana kupfekedza nekunamatira kwakanaka pamusoro pechigadzirwa chave chiri reground.
Kunze kwekucheka kwekucheka, iyo yakasara yechishandiso chepamusoro inogona kusada kuvharwa kana kudzokororwa panguva imwe neimwe yekukuya kwechishandiso, zvichienderana nerudzi rwechishandiso uye maparamita ekucheka anoshandiswa mukugadzira.Hobs uye broaches zvigadziro zvinoda kubvisa zvese zvepakutanga zvekuputira kana uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchi dzokoro , zvika daro mashandiro emidziyo .Pamberi pedambudziko rekunamatira rinokonzerwa nekunetseka rinove rakakurumbira, chishandiso chinogona kudzokororwa kakati wandei pasina kubvisa jira rekare.Kunyangwe PVD coating ine yasara yekumanikidza kushushikana kunobatsira kucheka simbi, kudzvanywa uku kuchawedzera nekuwedzera kweiyo coating ukobvu, uye iyo coating inotanga kudonha mushure mekudarika yakatarwa.Paunenge uchidzokorora pasina kubvisa chifukidzo chekare, hupamhi hunowedzerwa kune dhayamita yekunze yechishandiso.Pachibhorani, zvinoreva kuti dhayamita yegomba iri kuwedzera.Naizvozvo, zvinodikanwa kuti titarise pesvedzero yekuwedzera kukora kwejasi padhayamita yekunze yechishandiso, pamwe nepesvedzero yezviviri pane dimensional kushivirira kweiyo machined gomba dhayamita.
Chibooreso chinogona kuputirwa ka5 kusvika ka10 pasina kubvisa chivharo chekare, asi mushure meizvozvo, chinozosangana nematambudziko akakura ekukanganisa.Dennis Klein, mutevedzeri wemutungamiri weSpecial Tools, akatenda kuti ukobvu hwekuvharisa kwaisazova dambudziko mukati mekukanganisa kwe ± 1 µ m;Nekudaro, kana iko kukanganisa kuri mukati meiyo 0.5 ~ 0.1 µ m, pesvedzero yehukobvu hwekuputira inofanirwa kutariswa.Chero bedzi ukobvu hwekufukidzira husingaite dambudziko, maturusi akadzokororwa uye epasi anogona kuve nekuita zvirinani pane zvekutanga.
