Kusarudza drill bit yakakodzera purojekiti yako kunosanganisira kunzwisisa zvinhu zvitatu zvakakosha: zvinhu, coating, uye geometric features. Chimwe nechimwe chezvinhu izvi chinoita basa rakakosha mukushanda uye kugara kwenguva refu kwedrill bit. Heino tarisiro yakanyanya yekuti ungasarudza sei neruzivo rwakadzama.
Zvinhu
1. Simbi Inomhanya Zvikuru (HSS):
Simbi Yekumhanya Kwazvo (HSS) yave iri chinhu chakakosha mukucheka maturusi kweanopfuura zana remakore, ichikosheswa nekushandiswa kwayo kwakakura uye mutengo wayo wakaderera. HSS drill bits inozivikanwa nekushanda kwadzo kwakasiyana-siyana, ichishanda zvakanaka nemaoko ekuboorera uye mapuratifomu akagadzikana akadai sedrill presses. Chinhu chikuru cheHSS kugona kwayo kurodzazve, kuwedzera hupenyu hwemaboorera uye kuita kuti ive sarudzo inodhura zvishoma yelathe tools zvakare. Uyezve, HSS ine mamakisi akasiyana, imwe neimwe ine macomposition akasiyana kuti ikwane zvinodiwa zvekucheka. Mhando iyi yemakisi esimbi inowedzera kuchinjika kweHSS, zvichiita kuti ive chinhu chinoshanduka uye chakakosha mumabasa akasiyana-siyana ekugadzira.
2. Cobalt HSS (HSSE kana HSSCO):
Zvichienzaniswa neHSS yechinyakare, Cobalt HSS inoratidza kuomarara kwakanyanya uye kutsungirira kupisa. Kuvandudzwa uku muhunhu kunotungamira mukuvandudzwa kwakanyanya kwekudzivirira kukwesha, zvichiita kuti zvidimbu zveHSSE zvekuboorera zvigare kwenguva refu uye zvinobudirira. Kuiswa kwecobalt muHSSE hakungobatsiri chete mukuwedzera kwekudzivirira kukwesha asiwo kunowedzera hupenyu hwayo hwese. Kufanana neHSS yakajairwa, zvidimbu zveHSSE zvinoramba zvichibatsira nekugona kurodzwazve, izvo zvinowedzera hupenyu hwazvo hwekushandisa. Kuvapo kwecobalt muHSSE kunoita kuti zvidimbu izvi zvinyanye kukodzera mabasa ekuboorera akaomarara uko kugara kwenguva refu uye kuramba kukwesha kwakakosha.
3. Kabhoyidhi:
Carbide isimbi yakagadzirwa netungsten carbide ine ma binders akasiyana-siyana. Inopfuura HSS zvakanyanya pakuoma, kutsungirira kupisa, uye kuramba kukwesha. Kunyange zvazvo ichidhura, maturusi ecarbide anoshanda zvakanaka pakurarama uye kumhanya kwemuchina. Anoda michina yakasarudzika yekurodza zvakare.
Kuputira
Machira ekuisa zvidimbu zvesimbi anosiyana-siyana uye anosarudzwa zvichienderana nekushandiswa kwawo. Heino pfupiso yemamwe machira akajairika:
1. Isina kuputirwa (Yakajeka):
Ndiwo ruvara rwakanyanya kushandiswa pakugadzira mabhora eHSS. Yakanakira zvinhu zvakapfava zvakaita searuminiyamu alloys nesimbi isina kabhoni yakawanda, zvishandiso zvisina kuputirwa ndizvo zvinonyanya kudhura.
2. Kupfeka kweOxide Nhema:
Inopa mafuta ekuzora uye inodzivirira kupisa zviri nani pane zvishandiso zvisina kuputirwa, zvichiita kuti hupenyu hwemuchina huve nani ne50%.
3. Kupfeka Titanium Nitride (TiN):
Zvidhinha zveTitanium-coated drill zvinobudirira mumabasa akawanda nekuda kwehunhu hwazvo hwakasiyana hwekushanda. Chekutanga, Zvinowedzera kuomarara uye kuramba kwekukweshana kuburikidza ne coating, zvichiita kuti chidimbu chirambe chakapinza paunenge uchiboora zvinhu zvakaoma, uye zvichipa hupenyu hwebasa hwakareba. Zvidhinha izvi zvinoderedza kukweshana uye kupisa, zvichiwedzera kushanda zvakanaka kwekucheka uku zvichidzivirira chidimbu kubva pakupisa zvakanyanya. Zvidhinha zveTitanium-plated zvakakodzera kushandiswa muzvinhu zvakawanda, zvakaita sesimbi isingatsvi, aruminiyamu nehuni, zvichiita kuti zvive zvakanaka pakushandisa mainjiniya nepamba. Pamusoro pezvo, zvidhinha izvi zvinopinda muzvinhu nekukurumidza uye zvakachena, zvichipa nzvimbo yekucheka yakarongeka. Kunyange zvazvo zvidhinha zveTitanium-plated drills zvingadhura kupfuura zvidhinha zvenguva dzose, kushanda kwazvo uye hupenyu hurefu zvinoita kuti zvive purofiti yakanaka pakushandisa zvinoda kuramba kwakanyanya kwekukweshana uye kucheka kwakanyatsojeka.
4. Kupfeka kweAluminium Titanium Nitride (AlTiN):
Chekutanga, machira eAlTiN anodzivirira kupisa zvakanyanya, zvichivagonesa kucheka nekumhanyisa machira emhando yepamusoro. Chechipiri, machira aya anovandudza zvakanyanya kuramba kwekukwesha uye anowedzera hupenyu hwematurusi, kunyanya pakugadzira zvinhu zvakaoma zvakaita sesimbi isingatsvi, titanium alloys uye nickel-based alloys. Pamusoro pezvo, machira eAlTiN anoderedza kukweshana pakati pechibhorani nechinhu chebasa, zvichivandudza mashandiro emuchina uye zvichibatsira kuwana nzvimbo yekucheka yakatsetseka. Inewo kuramba kwakanaka kweoxidation uye kugadzikana kwemakemikari, zvichiita kuti irambe ichishanda munzvimbo dzakaoma dzekushanda. Pamwe chete, machira eAlTiN-coated akakodzera mashandisirwo emuchina anomhanya uye akanyatsonaka, uye anonyanya kukodzera kubata zvinhu zvakaoma zvinonetsa kumachira echinyakare.
Zvimiro zveJomethri
1. Kureba:
Chiyero chehurefu nedhayamita chinokanganisa kuomarara. Kusarudza drill bit ine urefu hwakakwana hweflute yekubvisa chips uye overhang shoma kunogona kuwedzera kuomarara uye hupenyu hwechishandiso. Kusakwana kweflute kunogona kukanganisa bit. Kune mwero wakasiyana-siyana wehurefu hwekusarudza pamusika. Humwe hurefu hwakajairika ndehwekuti Jobber, stubby, DIN 340, DIN 338, nezvimwewo.
2. Angle yeDrill Point:
Kona ye118° inowanzoitika kune simbi dzakapfava dzakadai sesimbi isina kabhoni yakawanda nearuminiyamu. Kazhinji haina kugona kuzvimisikidza, inoda gomba rekupirinda. Kona ye135°, ine hunhu hwayo hwekuzvimisikidza, inobvisa kudiwa kwegomba rakasiyana rekumisikidza, zvichichengetedza nguva yakawanda.
Mukupedzisa, kusarudza drill bit yakakodzera kunosanganisira kuyera zvinodiwa nezvinhu zviri kubhorwa, hupenyu hwebhiti hwaunoda uye mashandiro ahwo, uye zvinodiwa chaizvo zvepurojekiti yako. Kunzwisisa zvinhu izvi kuchaita kuti usarudze drill bit inoshanda uye inoshanda zvakanyanya zvinoenderana nezvaunoda.
