Ukukhethwa Kwama-Cruits Okusika Kwabasiki Be-Metallographic

Uma usebenzisa umshini wokusika we-metallographic onembile ukusika izingcezu zomsebenzi, kubalulekile ukukhetha izingcezu zokusika ezifanelana nezakhiwo zezinto zokusebenza ze-workpiece ngokusekelwe ezintweni zayo ezahlukene, ukuze kutholakale imiphumela yokusika ephumelelayo. Ngezansi, sizoxoxa ngokukhethwa kwezingcezu zokusika ngezindlela ezintathu:

1. Ukukhetha Okusekelwe Ezimpahleni Zezinto Ezibalulekile

1) Ezintweni zensimbi ezifana nensimbi, insimbi, kanye nama-alloy, kufanele kusetshenziswe ama-blade okusika ahlanganiswe ne-resin. Ubukhulu bawo buvame ukuba phakathi kuka-1-2 mm, okufanelekela ukusika kahle izinto zensimbi ezifana nensimbi eqinile. Indawo Ethintekile Ekushiseni nayo iyasebenza ezimweni zokusika ngokunemba njengokuhlaziywa kwe-metallographic. Ngaphezu kwalokho, umonakalo wokusika ungancishiswa ngempumelelo ngokulungisa izinga lokuphakelwa.

2) Ukuze uthole izinto ezingonakalisi njenge-ceramic nengilazi, kudingeka ama-blade okusika idayimane. Lawa ma-blade anobulukhuni obuphezulu kanye nokushisa okuhle, okunganciphisa ingozi yokulimala kokushisa.

3) Embonini ye-semiconductor, isekethe ehlanganisiwe, kanye ne-PCB, ama-blade okusika idayimane acwebezelayo asetshenziswa kabanzi ekulawuleni ikhwalithi kanye nokuhlaziya ukwehluleka.

2. Ukukhetha Okusekelwe Ezidingweni Zokusika Okungaphezulu kanye Nezidingo Zokusebenza Kahle

1) Uma umsebenzi ungadingi ukuguquguquka kanye nokuhlanzeka okuphezulu kwendawo, khetha ama-cutting blades amancane (ukujiya: 0.3-1.0 mm). Lawa ma-blades anciphisa ungqimba lomonakalo wokusika futhi enze kube lula izinqubo zokugaya ezilandelayo.

2) Uma kudingeka isivinini esikhulu sokusika kanye nokusebenza kahle, khetha ama-cutting blades aqinile (ukujiya: 1.2-3.0 mm). Lawa ma-blades anokuqina okuphezulu, akulula ukuwaphula, futhi afaneleka ukusika ngebhetshi.

3.Ukukhethwa Ngokusekelwe Kubulukhuni Bezinto Zokusebenza

Ubulukhuni bento yokusebenza bunquma ngqo ukukhethwa kwezinto zensingo yokusika. Okwamanje, kubalulekile ukucabangela izidingo ezishiwo ngenhla zamasinde amancane noma aqinile (ngokusekelwe kwikhwalithi/ukusebenza kahle kobuso). Uma ubulukhuni bento yokusebenza buphakeme, kulapho insingo yokusika idinga ukumelana nokuguguleka futhi iqine khona.

1) Izinto zokusebenza ezinobulukhuni obuphezulu (＞HRC 50, isib., insimbi eqinile, i-carbide eqinisiwe, insimbi enekhabhoni ephezulu)

Ama-blade okusika afanelekile: Ama-blade okusika edayimane noma ama-cubic boron nitride (CBN)

Ubukhulu obunconywayo: Okubaluleke kakhulu kunikezwa ama-blade amakhulu (1.2-3.0 mm). Aqinile futhi amelana nokuguguleka okuphezulu, okungavimbela ukuqhekeka ngesikhathi sokusika. Izinto zokusebenza ezinobunzima obukhulu zivame ukuguguleka ama-blade avamile okusika, ngakho-ke izinto ezingagugi zingaqinisekisa ukusebenza kahle kokusika; isakhiwo esiqinile sifanelekela ukusika umthwalo omkhulu.

2) Izinto zokusebenza ezinobulukhuni obuphakathi nendawo (HRC 30-50, isib., insimbi yekhabhoni evamile, insimbi ephonswe, insimbi engagqwali)

Ama-blade okusika afanelekile: Ama-blade okusika edayimane aboshwe nge-resin noma ama-blade okusika e-alumina asezingeni eliphezulu

Ubukhulu obunconywayo: Ukukhetha okuguquguqukayo — khetha ama-blade amancane (0.3-1.0 mm) ukuze uthole ukuhlanzeka okuphezulu kwendawo, noma ama-blade amakhulu (1.2-3.0 mm) ukuze kucutshungulwe ngeqoqo. Njengoba ubulukhuni bezinto buphakathi, ama-blade okusika ajwayelekile angagugi angahlangabezana nezidingo zokusika, futhi ama-blade amancane/amakhulu angalinganiswa ngokwekhwalithi yendawo noma izidingo zokusebenza kahle.

3) Izinto zokusebenza ezinobulukhuni obuphansi (

Ama-blade okusika afanelekile: Ama-blade okusika e-alumina ajwayelekile noma ama-blade okusika edayimane amancane

Ubukhulu obunconywayo: Kunikezwa kuqala ama-blade amancane (0.3-0.8 mm); ama-blade angu-1.0 mm angakhethwa kwezinye izinto. Ama-workpiece anobulukhuni obuphansi athambekele ekunamatheleni nasekuguqukeni kwamathuluzi; ama-blade amancane okusika anciphisa indawo yokuxhumana, agweme ukunamathela kwamathuluzi kanye nomonakalo we-workpiece. Izinto ezivamile ze-blade yokusika zanele ukuhlangabezana nezidingo zokusika.

Amanothi Okugcina Okukhethwa Kokusika I-Blade:

Umphumela wokusika kanye nempilo yesevisi yezinsika zokusika ezisetshenziswa ngokujwayelekile kuzoncipha kakhulu uma kusetshenziswa ezintweni ezithile.

I-blade yokusika kufanele ikhethwe ngokuya ngokucushwa kwe-metallographic cutter esetshenziswayo. Isibonelo, gwema ukusebenzisa ama-cutting blade amakhulu ngangokunokwenzeka kuma-cutter anamandla aphansi, njengoba lokhu kungabangela kalula ukugcwala kwenjini noma ukuphuka kwe-cutting blade.
