Kusankha kwa zida za carbide ndikofunikira kwambiri.
2023-09-22

The choice of carbide tool material is particularly important.


Ukadaulo wosavuta wopangira ma fani ndi kusungunula-kuponyera-annealing-rough Machining-quenching, kutentha-kumaliza. Kulimba kwa chogwirira ntchito pambuyo pozimitsa ndi kutentha nthawi zambiri kumakhala pamwamba pa HRC45. Pazigawo zachitsulo zolimba kwambiri, zida zodulira zachikhalidwe (zida zodulira carbide ndi zida zodulira ceramic) sizingakwaniritsenso zofunikira pakukonza. Kuchita kwa zida za simenti za carbide sikufotokozedwa mwatsatanetsatane apa. Pakadali pano, zida zopangira zida zachitsulo zolimba kwambiri zimaphatikizanso zida za ceramic ndi zida za cubic boron nitride. Zida za Ceramic zimadziwika bwino kuti ndizosasunthika ndipo sizingatembenuzidwe ndi malire akulu. Kudula kwapakatikati sikuloledwa. Ngati mapindikidwe a workpiece pambuyo mankhwala kutentha ndi yaing'ono, pamwamba ndi yosalala, ndipo malire ndi yaing'ono, ndi bwino kusankha zida za ceramic.


Malinga ndi zogwirira ntchito zosiyanasiyana, kuuma, ndi malipiro, sankhani zida zoyenera za carbide ndi magawo odulira. Ndondomekoyi ili motere:



(1) Finely anatembenuzika slewing kubala carbide raceway, mapeto nkhope, kuuma HRC47-55, malipiro

Kukonzekera: Moyo wa chida cha carbide yopangidwa ndi simenti ndi nthawi 7 kuposa zida za ceramic, ndipo kuuma kwapamwamba kumayendetsedwa pakati pa Ra0.6-1.0.



(2) Anamaliza kutembenukira kwa kupha kubala carbide bwalo lakunja, mapeto nkhope, kuuma HRC47-55, channel kuuma HRC55-62; m'mphepete ≥ 2mm

Kukonzekera: Chida cha Carbide chimakhala ndi moyo wautali wa chida ndipo chimatha m'malo mwa akupera, ndipo kuuma kwa pamwamba kumafika pa Ra0.4.



(3) Finely anatembenuza zitsulo carbide bwalo akunja ndi dzenje lamkati, kuuma HRC62:

Processing zotsatira: Poyerekeza ndi zida kudula achilendo, ali ndi moyo wautali utumiki ndi roughness pamwamba ndi mkati Ra0.8.
