1. AboutGraphite milling cutter
Kuenzaniswa nemhangura electrode, magraphite electrode ane zvakanakira senge yakaderera electrode kushandiswa, kukurumidza kugadzirisa kukurumidza, yakanaka mechanical processing performance, high processing accuracy, small thermal deformation, lightweight, easy surface treatment, high temperature resistance, high processing temperature, uye electrode adhesion. .
Kunyange zvazvo graphite ichinhu chiri nyore kwazvo kutema, girafu inoshandiswa seEDM electrode inofanira kuva nesimba rakakwana kuti rirege kukuvadza panguva yekushanda uye EDM processing.Panguva imwecheteyo, chimiro che electrode (yakatetepa-yakakomberedzwa, madiki akatenderedzwa makona, yakapinza shanduko, nezvimwewo) inoisawo zvakakwirira zvinodiwa pakukura kwezviyo uye kusimba kweiyo graphite electrode, izvo zvinotungamira kune graphite workpiece kuve nyore kutsemuka uye chishandiso. kupfeka panguva yekugadzirisa.
2. Graphite milling toolzvinhu
Chishandiso chemidziyo ndicho chinhu chakakosha chinotaridza kucheka mashandiro echishandiso, icho chine simba rakakura pakuita machining, mhando, mutengo, uye kusimba kwechishandiso.Kunyanya kuoma kwemidziyo, zviri nani kusakara kwayo, kukwira kwayo kuoma, kuderera kwayo kusimba kwayo, uye kunowedzera brittle zvinhu.
Kuomarara uye kuomarara zvinopokana uye chinhu chakakosha chinofanira kutariswa nemidziyo yekushandisa.
Kune maturusi ekucheka magirafu, machira eTIAIN akajairwa anogona kusarudza zvinhu zvine kusimba kuri nani, kureva, izvo zvine cobalt yakakwira zvishoma;Kune madhaimondi akavharidzirwa magirafu ekucheka maturusi, zvinhu zvine hurema hwakati wandei, kureva ine yakaderera cobalt yemukati, inogona kusarudzwa zvakakodzera.
3. Chishandiso geometry angle
Zvishandiso zvakakosha zvekucheka magirafuKusarudza yakakodzera geometric angle kunobatsira kudzikisa kuzunguzika kwechishandiso, uye ukuwo, magirafu emabasa emaoko haanawo kukurumidza kuputsika.
anterior angle
Paunenge uchishandisa negative rake angle kugadzirisa graphite, simba remupendero wechombo rakanaka, uye kupikisa kwemaitiro uye kuita kwekukwenya kwakanaka.Sezvo kukosha kwakazara kweiyo negative rake angle kunodzikira, nzvimbo yekupfeka yekumashure chishandiso haichinji zvakanyanya, asi yakazara inoratidza kudzikira maitiro.Paunenge uchishandisa yakanaka rake angle kugadzirisa, sezvo iyo rake angle inowedzera, iyo yemudziyo simba rekushandisa inodzikira, uye pachinzvimbo, kupfeka kweyekumashure chishandiso kunowedzerwa.Paunenge uchigadzira neakaipa rake angle, kucheka kupikisa kwakakwirira, izvo zvinowedzera kudengenyeka kwekucheka.Paunenge uchigadzira nehombe yakanaka rake angle, chishandiso chinopfeka chakanyanya, uye kucheka vibration zvakare kwakakwira.
kona yekuyamura
Kana iyo kona yekumashure ichiwedzera, simba remupendero wezvishandiso rinoderera uye nzvimbo yekupfeka yekumashure chishandiso inowedzera zvishoma nezvishoma.Kana iyo kona yekumashure yechishandiso yakakura kwazvo, kucheka vibration kunowedzera.
helix angle
Kana iyo helix angle idiki, kureba kwekucheka kumucheto kunocheka panguva imwe chete mukati megraphite workpiece pamativi ese ekucheka kwakareba, kushomeka kwekucheka kwakakura, uye simba rekucheka rinotakurwa nechishandiso rakakura, zvichikonzera kupfeka kukuru kwemidziyo. , simba rekugaya, uye kucheka kudengenyeka.Kana iyo helix angle yakakura, kutungamira kwesimba rekugaya kunotsauka zvakanyanya kubva pamusoro peiyo workpiece.Iko kucheka kunokonzerwa nekutsemuka kwezvinhu zvegraphite kunowedzera kupfeka, uye kukanganisa kwesimba rekugaya uye kucheka vibration musanganiswa wekona yekumberi, kumashure kwekona, uye helix angle.Nokudaro, zvakakosha kubhadhara zvakanyanya pakusarudza.
3.end mill ye graphite coating
PCD yekuputira maturusi ekucheka vane zvakanakira senge kuomarara kwakanyanya, kunaka kupfeka kuramba, uye yakaderera friction coefficient.
Parizvino, kupfekedzwa kwemadhaimani ndiyo yakanakisa sarudzo yezvishandiso zvegraphite machining uye inogona kuratidza zvakanyanya kuita kwepamusoro kwezvishandiso zvegraphite.Chakanakira chedhaimani chakavharidzirwa carbide chishandiso ndechekuti inosanganisa kuoma kwedhaimani rechisikigo nesimba uye Fracture kuoma kwecarbide.
Iyo geometric angle yedhaimani yakavharwa maturusi akasiyana zvakanyanya kubva kune akajairwa majasi.Naizvozvo, kana uchigadzira maturusi akavharidzirwa nedhaimani, nekuda kwechimiro chakakosha chekugadzirisa graphite, kona yejometri inogona kukwidziridzwa zvakafanira, uye chip inobata groove inogona zvakare kukwidziridzwa, pasina kudzikisa kupfeka kuramba kwechishandiso.Kune akajairwa TIAIN coatings, kunyangwe kupfeka kwavo kuramba kwakavandudzwa zvakanyanya kana zvichienzaniswa nemidziyo isina kuvharwa, zvichienzaniswa nedhaimani coatings, kona yejometri inofanira kuderedzwa zvakafanira kana machining graphite kuti iwedzere kusakara kwayo.
4. Blade passivation
Iyo passivation tekinoroji yekucheka kumucheto inyaya yakakosha iyo isati yazivikanwa zvakanyanya.Kukosha kwayo kuri muchokwadi chekuti passivated chishandiso chinogona kunyatso kuvandudza simba rekumucheto, hupenyu hwechishandiso, uye kugadzikana kwekucheka maitiro.Isu tinoziva kuti maturusi ekucheka ndiwo "mazino" emidziyo yemuchina, uye zvinhu zvikuru zvinokanganisa kucheka mashandiro uye hupenyu hwematurusi.Pamusoro pemidziyo yekushandisa, chishandiso geometric paramita, dhizaini dhizaini, yekucheka parameter optimization, nezvimwewo, kuburikidza nenhamba yakawanda yezvishandiso edge passivation maitiro, takaona kuti kuve neakanaka emupendero fomu uye mupendero passivation mhando zvakare chinhu chinodiwa kune chishandiso. kukwanisa kuita zvakanaka kucheka kugadzirwa.Nokudaro, mamiriro ekucheka kwekucheka zvakare chinhu chisingagoni kuregererwa
5. Kucheka nzira
Kusarudzwa kwemamiriro ekucheka kune zvakakosha pahupenyu hwekushandisa.
Iko kucheka kwekucheka kwekuya kwemberi kudiki pane kuya kwereverse milling.Panguva yekugaya kumberi, kukora kwechishandiso kunoderera kubva pakakwirira kusvika zero.Mushure mekunge chishandiso chacheka mukati meiyo workpiece, hapazove nebouncing phenomenon inokonzerwa nekusakwanisa kucheka machipisi.Iyo nzira yemaitiro ine yakanaka kuomarara uye yakaderera yekucheka vibration;Munguva yekudzosera kumashure, ukobvu hwekucheka kwechishandiso hunowedzera kubva ku zero kusvika pakukwirira.Muchikamu chekutanga chekucheka, nekuda kwehupamhi hwekucheka hutete, nzira ichatorwa pamusoro pebasa rekushanda.Panguva ino, kana iyo yekucheka ikasangana neakaomesesa mapoinzi mune graphite zvinhu kana zvakasara chip particles pamusoro peiyo workpiece, ichaita kuti chishandiso chibhururuke kana kudedera, zvichikonzera kudengenyeka kukuru kwekucheka panguva yekudzosera kumashure.
Kufuridza (kana vacuuming) uye kunyudzwa mumagetsi ekuburitsa fluid machining
Kucheneswa nenguva kweguruva regraphite pamusoro pechishandiso kunobatsira kuderedza kusapfeka kwechishandiso chechipiri, kurebesa hupenyu hwesevhisi yezvishandiso, uye kuderedza kukanganiswa kweguruva regraphite pamashini echishandiso screws uye madhairekitori.
