Kusankha Masamba Odulira a Metallographic Cutters

Mukagwiritsa ntchito chodulira cha metallographic cholondola podula zidutswa zogwirira ntchito, ndikofunikira kusankha masamba odulira omwe akugwirizana ndi mawonekedwe a chidutswacho kutengera zida zake zosiyanasiyana, kuti mupeze zotsatira zabwino zodulira. Pansipa, tikambirana za kusankha masamba odulira kuchokera mbali zitatu:

1. Kusankha Kutengera Katundu wa Zinthu

1) Pazinthu zachitsulo monga chitsulo, chitsulo, ndi zitsulo zosungunulira, masamba odulira olumikizidwa ndi utomoni ayenera kugwiritsidwa ntchito. Kukhuthala kwawo nthawi zambiri kumakhala pakati pa 1-2 mm, komwe ndikoyenera kudula bwino zinthu zachitsulo monga chitsulo cholimba. Malo Okhudzidwa ndi Kutentha amagwiritsidwanso ntchito pazinthu zodula molondola monga kusanthula kwa metallographic. Kuphatikiza apo, kuwonongeka kwa kudula kumatha kuchepetsedwa bwino posintha kuchuluka kwa chakudya.

2) Pa zinthu zosalimba monga zadothi ndi galasi, masamba odulira diamondi amafunika. Masamba awa ali ndi kuuma kwambiri komanso kutentha kwabwino, zomwe zimachepetsa chiopsezo cha kuwonongeka kwa kutentha.

3) Mu mafakitale a semiconductor, integrated circuit, ndi PCB, masamba odulira diamondi opyapyala kwambiri amagwiritsidwa ntchito kwambiri powongolera khalidwe ndi kusanthula kulephera.

2. Kusankha Kutengera Zofunikira Zodulira Pamwamba ndi Zofunikira Zogwira Ntchito Mwachangu

1) Ngati chogwirira ntchito sichikufuna kusintha kwa mawonekedwe ndi kuyera kwambiri pamwamba, sankhani masamba odulidwa opyapyala (makulidwe: 0.3-1.0 mm). Masamba awa amachepetsa kuwonongeka kwa choduliracho ndipo amathandizira njira zopukutira pambuyo pake.

2) Ngati pakufunika kudula mwachangu komanso kugwiritsa ntchito bwino, sankhani masamba okhuthala (makulidwe: 1.2-3.0 mm). Masamba awa ndi olimba kwambiri, ndi osavuta kuswa, ndipo ndi oyenera kudula m'magulu.

3.Kusankha Kutengera Kuuma kwa Ntchito

Kuuma kwa chogwirira ntchito kumatsimikiza mwachindunji kusankha kwa tsamba lodulira. Pakadali pano, ndikofunikira kuganizira zofunikira zomwe zatchulidwazi za masamba owonda kapena okhuthala (kutengera mtundu/kugwira ntchito bwino kwa pamwamba). Kuuma kwa chogwirira ntchito kukakhala kwakukulu, tsamba lodulira liyenera kukhala lolimba komanso losawonongeka.

1) Zipangizo zogwirira ntchito zolimba kwambiri (＞HRC 50, mwachitsanzo, chitsulo cholimba, carbide yolimba, chitsulo chokhala ndi mpweya wambiri)

Masamba odulira oyenera: Masamba odulira a diamondi kapena masamba odulira a cubic boron nitride (CBN)

Kukhuthala koyenera: Masamba okhuthala (1.2-3.0 mm) ndi ofunikira kwambiri. Ali ndi kulimba kwambiri komanso kukana kusweka, zomwe zingalepheretse kusweka podula. Masamba odulira olimba kwambiri nthawi zambiri amawonongeka ndi masamba wamba odulira, kotero zinthu zosatha kusweka zimatha kuonetsetsa kuti kudula kumagwira ntchito bwino; kapangidwe kake kokhuthala ndi koyenera kudula kwambiri.

2) Zogwirira ntchito zolimba zapakati (HRC 30-50, mwachitsanzo, chitsulo cha kaboni wamba, chitsulo choponyedwa, chitsulo chosapanga dzimbiri)

Masamba odulira oyenera: Masamba odulira diamondi olumikizidwa ndi utomoni kapena masamba odulira alumina apamwamba kwambiri

Kukhuthala koyenera: Kusankha kosinthasintha — sankhani masamba opyapyala (0.3-1.0 mm) kuti muyeretse bwino pamwamba, kapena masamba okhuthala (1.2-3.0 mm) kuti mugwiritse ntchito. Popeza kuuma kwa zinthuzo ndi kochepa, masamba odulidwa wamba omwe satha kusweka amatha kukwaniritsa zosowa zodulira, ndipo masamba oonda/okhuthala amatha kufananizidwa malinga ndi mtundu wa pamwamba kapena zofunikira pakugwira bwino ntchito.

3) Zogwirira ntchito zotsika kuuma (

Masamba oyenera kudula: Masamba odulira a alumina wamba kapena masamba owonda odulira a diamondi

Kukhuthala koyenera: Masamba owonda (0.3-0.8 mm) ndi ofunika kwambiri; masamba a 1.0 mm akhoza kusankhidwa pa zinthu zina. Masamba ouma pang'ono amatha kumamatira ndi kusintha kwa zida; masamba odulidwa opyapyala amachepetsa malo olumikizirana, kupewa kumamatira kwa zida ndi kuwonongeka kwa ntchito. Zipangizo wamba zodulira ndi zokwanira kukwaniritsa zosowa zodulira.

Zolemba Zomaliza Zosankha Tsamba Lodula:

Mphamvu yodulira ndi nthawi yogwira ntchito ya masamba odulira ogwiritsidwa ntchito nthawi zonse zimachepa kwambiri zikagwiritsidwa ntchito pazinthu zinazake.

Tsamba lodulira liyenera kusankhidwa malinga ndi kalembedwe ka chodulira cha metallographic chomwe chikugwiritsidwa ntchito. Mwachitsanzo, pewani kugwiritsa ntchito masamba okhuthala odulira pa zodulira zamphamvu zochepa momwe mungathere, chifukwa izi zingayambitse kudzaza kwa injini kapena kusweka kwa tsamba lodulira.
