Mukugadzirisa kwekugaya, nzira yekusarudza yakakodzeraCARBIDE END MILLuye kutonga kupfekwa kwechigayo chekucheka munguva haigone chete kuvandudza mashandiro ekugadzirisa, asi zvakare kuderedza mutengo wekugadzirisa.
Zvinodikanwa Zvekutanga zveEnd Mill zvinhu:
1. High kuoma uye kupfeka kuramba
Pakupisa kwakajairika, chikamu chekucheka chechinhu chinofanira kunge chakaoma chakakwana kuti chicheke mukati meiyo workpiece; nekukwirira kupfeka kusagadzikana, chishandiso hachizopfeki uye kuwedzera hupenyu hwebasa.
2. Good heat resistance
Chishandiso chichaunza kupisa kwakawanda panguva yekucheka, kunyanya kana kukurumidza kwekucheka kwakakwira, kutonhora kuchave kwakanyanya.
Naizvozvo, mudziyo wekushandisa unofanirwa kuve wakanaka kupisa kupisa, izvo zvinogona kuchengetedza kuomarara kwakanyanya kunyangwe pakupisa kwakanyanya, uye zvine kunaka kwekupisa. Iko kugona kuenderera mberi nekucheka, iyi pfuma ine yakanyanya tembiricha kuoma, inozivikanwawo sekuoma kunopisa kana kuomarara kwakatsvuka.
3. Simba repamusoro uye kuoma kwakanaka
Muchigadziro chekucheka, mudziyo unofanirwa kutakura simba rakakura rekuita, saka chishandiso chinofanira kunge chine simba rakawanda, zvikasadaro zviri nyore kutyora uye kukanganisa. Kubva pamilling cutteriri pasi pekukanganiswa uye kuzununguka, zvinhu zvechigayo chekucheka zvinofanirwawo kuve nekusimba kwakanaka, kuitira kuti zvisave nyore chip uye kutyora.
Zvikonzero zvekupfeka zvigayo zvekucheka
Zvikonzero zvekupfeka kwekupera zvigayozvakanyanya kuomarara, asi zvinogona kuganhurwa kana kunyanya kukamurwa kuita mapoka maviri:
1. Mechanical kupfeka
Kupfeka kunokonzerwa nekukakavadzana kwakanyanya pakati pechip uye raki kumeso kwechishandiso, iyo elastic deformation yemuchina wakagadzirwa pamusoro peiyo workpiece uye flank yechishandiso inonzi mechanical wear. Kana tembiricha yekucheka isati yanyanya kukwirira, iyo mechanical abrasion inokonzerwa nekukwesha iyi ndiyo inonyanya kukonzera kupfeka kwemidziyo.
2. Kupfeka kwekushisa
Panguva yekucheka, nekuda kwekuoma kwepurasitiki deformation yesimbi uye kupisa kwekucheka kunokonzerwa nekukakavadzana, kupfeka kunokonzerwa nekuderedzwa kwekuoma kweblade uye kurasikirwa kwekucheka kushanda kunonzi thermal wear.
Pamusoro pemhando mbiri dziri pamusoro dzekupfeka, kune marudzi anotevera ekupfeka:
Pasi pekushisa kwepamusoro uye kumanikidzika kwepamusoro, pachava nechisungo chekubatanidza pakati pechigadziro uye workpiece material, uye chikamu chezvishandiso chichabviswa nemachipisi, zvichiita kuti chigadziro chisungirwe uye chipfeke.
Pakupisa kwepamusoro, zvimwe zvinhu zviri mumudziyo wemidziyo (senge tungsten, cobalt, titanium, nezvimwewo) zvinopararira mukati mechinhu chebasa, zvichibva zvachinja kemikari yechikamu chepamusoro chechikamu chekucheka chemudziyo, uye kuderedza simba. uye kupfeka kuramba kwechishandiso, kuitira kuti chishandiso chibudise kupfeka kwekupararira.
Kune maturusi esimbi anomhanya-mhanya, patembiricha yepamusoro yekucheka, iyo metallographic chimiro chepamusoro pechishandiso chinoshanduka, ichideredza kuomarara uye kupfeka kuramba, uye chikamu chekuchinja chinopfeka chichaitika. Zino rega rega rekucheka kwegayo i periodic intermittent cut. Kupisa kwezino kunosiyana zvakanyanya kubva pakurova kusina basa kusvika pakucheka. Zvinogona kutaurwa kuti nguva imwe neimwe iyo inopinda mukucheka, inokonzerwa nekupisa kwekushisa. Carbide zvishandiso, pasi pekuvhunduka kwekupisa, zvinoburitsa kushushikana kwakawanda mukati meblade, uye zvichikonzera kuputika, zvichikonzera kuputika kwekupisa uye kupera kwechishandiso. Sezvo chigayo chekucheka chichicheka nguva nenguva, tembiricha yekucheka haina kukwira seiyo mukutendeuka, uye chikonzero chikuru chekupfeka kwechishandiso chinowanzo pfeka machira anokonzerwa nekukwesha kwemuchina.
Nzira yekuziva sei chipfeko chekushandisa?
1. Kutanga, tongai kana yakapfekwa kana kuti kwete panguva yekugadzirisa. Kunyanya mukucheka, teerera inzwi. Kamwe kamwe, ruzha rwechishandiso panguva yekugadzira hachisi chekucheka kwakajairika. Chokwadi, izvi zvinoda ruzivo kuunganidza.
2. Tarisa pakugadzirisa. Kana paine sparks dzisina kupindirana panguva yekugadziriswa, zvinoreva kuti chishandiso chakapfekwa, uye chishandiso chinogona kuchinjwa nekufamba kwenguva zvichienderana neavhareji yehupenyu hwechishandiso.
3. Tarisa ruvara rwemafaira esimbi. Rudzi rwemafaira esimbi rinoshanduka, zvichiratidza kuti tembiricha yekugadzira yakashanduka, iyo inogona kunge iri yekupfeka kwechishandiso.
4. Tichitarisa chimiro chesimbi, kune maumbirwo akaitwa kumativi ose maviri emapuranga esimbi, mafirita ematare akakomberedzwa zvisina kujairika, uye simbi inoputika inova yakanaka, izvo zviri pachena kuti haisi manzwiro ekucheka kwemazuva ose, izvo zvinoratidza kuti. mudziyo wapfekwa.
5. Kutarisa pamusoro pebasa rekushanda, kune mavara akajeka, asi hutsinye uye ukuru hazvina kuchinja zvakanyanya, izvo chaizvoizvo chimbo chave chakapfekwa.
6. Kuteerera kune ruzha, machining vibration anowedzera, uye chishandiso chinoburitsa ruzha rusina kujairika kana chishandiso chisina kukurumidza. Panguva ino, tinofanira kuchenjerera kudzivisa "kunamatira banga", izvo zvichaita kuti workpiece iparadzwe.
7. Cherekedza mutoro wemashini emuchina. Kana paine shanduko yakakosha yekuwedzera, chishandiso chinogona kupfekwa.
8. Kana chimbo chacho chikatemwa, workpiece ine yakakomba burrs, roughness inoderedzwa, saizi ye workpiece inoshanduka uye zvimwe zviri pachena zviitiko zvakare ndiyo nzira yekusarudza kupfeka chombo.
Muchidimbu, kuona, kunzwa, uye kubata, chero uchikwanisa kupfupisa pfungwa imwe chete, unogona kutonga kuti chishandiso chakapfekwa here kana kuti kwete.
Nzira dzekudzivisa kushandiswa kwemidziyo

7. Crescent kupfeka
Kuvandudza: kuderedza kukurumidza kutema; kuderedza kudya; shandisa zvipfeko zvakaputirwa kana kuisa cermet; shandisa coolant.
8. Kutyoka
Kuvandudza nzira: shandisa chinhu kana geometry nekusimba kuri nani; kuderedza kudya; kuderedza kudzika kwekucheka; tarisa kuomarara kweiyo process system.
Kana iwe uchida kutsvaga kuomarara kwakanyanya uye kupfeka zvisingaite zvigayo, huya kuzoona zvigadzirwa zvedu:
