Chikamu chedhaimondi ndicho chinoshanda chedhaimondi saw blade. Musoro wekucheka wedhaimani saw blade unoumbwa nedhaimondi uye matrix binder. Dhaimondi chinhu chakanyanya kuoma chinoshanda sekucheka. Iyo matrix binder inoita basa rekugadzirisa dhaimondi. Iyo inoumbwa neyakapfava simbi poda kana simbi alloy poda Kuumbwa, akasiyana maumbirwo anonzi mafomula, uye mafomula akasiyana nemadhaimani maererano nekushandiswa kwakasiyana.

1. Kusarudzwa kwe diamond particle size

Kana saizi yedhaimani yakakora uye saizi imwe chete, blade musoro wakapinza uye kugona kwesahwi kwakakwira, asi simba rekukotama redhaimani agglomeration rinodzikira; kana saizi yedhaimani yakanaka kana kuti akakasharara uye akatsetseka masaizi akasanganiswa, musoro wesaha une kusimba kwakanyanya, asi kushoma kushanda. Tichifunga pamusoro pezvinhu zviri pamusoro, zvakanyanya kufanira kusarudza saizi yedhaimondi ye50/60 mesh.

2. Kusarudzwa kwemadhaimondi ekugovera concentration

Mukati mehumwe huwandu, kana madhaimondi achinja kubva pasi kusvika kumusoro, kupinza uye kuchekwa kweiyo saw blade kunoderera zvishoma nezvishoma, nepo hupenyu hwesevhisi huchawedzera zvishoma nezvishoma; asi kana iyo yekuisa yakanyanya kuwanda, blade yesaha inogomara. Uye kushandiswa kweiyo yakaderera concentration, coarse particle size, kushanda zvakanaka kuchavandudzwa. Uchishandisa mabasa akasiyana echikamu chega chega chemucheki wemusoro panguva yekucheka, kutarisisa kwakasiyana kunoshandiswa (kureva kuti, yakaderera yekumisikidza inogona kushandiswa muchikamu chepakati mune matatu-layer kana kupfuura dhizaini chimiro), uye yepakati groove inoumbwa pairi. musoro wekucheka panguva yekucheka, iyo ine imwe mhedzisiro. Zvinobatsira kudzivirira blade yesaha kubva pakutsauka, nekudaro kuvandudza kunaka kwekugadzirwa kwematombo.

3. Kusarudzwa kwesimba redhaimani

Simba redhaimani chiratidzo chakakosha chekuvimbisa kucheka kuita. Kunyanya kusimba kuchaita kuti kristaro isave nyore kuputsa, zviyo zvinoputika zvichange zvakasvibiswa panguva yekushandiswa, uye kupinza kunoderera, zvichikonzera kukanganisa kwekushanda kwechishandiso; kana simba redhaimani risina kukwana, richaputsika nyore nyore mushure mekubatwa, uye zvakaoma kutakura mutoro unorema wekucheka. Nokudaro, simba rinofanira kusarudzwa pa 130-140N

4. Kusarudzwa kwebinder chikamu

Kuita kweshizha resaha hakubvi padhaimondi chete, asi pakuita kwese kwezvakaumbwa zvediamond saw blade uye musoro wekucheka wakaumbwa nekubatana kwakakodzera kwebhainda. Kune matombo akapfava ematombo akadai semarble, michina yemusoro wekucheka inodiwa kuti ive yakaderera, uye mabhaidhi emhangura anogona kushandiswa. Zvisinei, kupisa kwekupisa kwemhangura-based binder kwakaderera, simba uye kuoma kwakaderera, kuoma kwakakwirira, uye simba rekubatanidza nedhaimani rakaderera. Kana tungsten carbide (WC) yawedzerwa, WC kana W2C inoshandiswa sesimbi yeskeleton, ine huwandu hwakakodzera hwecobalt kuvandudza simba, kuoma uye kubatanidza maitiro, uye zvishoma zveCu, Sn, Zn uye mamwe masimbi ane zvishoma. melting point uye kuomarara kwakaderera kunowedzerwa pakubatanidza Mutually. Saizi yezvikamu zvikuru zvinofanirwa kuve zvakapfava kupfuura 200 mesh, uye saizi yechikamu chezvakawedzerwa zvinofanirwa kunge zviri nani kupfuura 300 mesh.

5. Kusarudzwa kwekuita sintering

Sezvo tembiricha ichiwedzera, dhigirii re densification yechitunha rinowedzera, uye simba rekushanduka-shanduka rinowedzerawo, uye nekuwedzera kwenguva yekubata, simba rekuchinjika rechitunha chisina chinhu uye madhaimani agglomerates anotanga awedzera obva aderera. Sintering pa800 ° C ye120s kuti isangane nekuita zvinodiwa.
