Abubuwan da ba daidai ba, duk a banza!
Akwai abubuwa da yawa da suka dace don sarrafa CNC.Don nemo kayan da ya dace don samfurin, an iyakance shi da abubuwa da yawa.Ka'ida ta asali wacce ke buƙatar bi ita ce: aikin kayan aikin dole ne ya dace da buƙatun fasaha daban-daban na samfurin da buƙatun amfani da muhalli.Lokacin zabar kayan sassa na inji, ana iya la'akari da waɗannan abubuwan 5 masu zuwa:
- 01 Ko rigidity na kayan ya wadatar
Rigidity shine la'akari na farko lokacin zabar kayan, saboda samfurin yana buƙatar ƙayyadaddun kwanciyar hankali da juriya a cikin aiki na ainihi, kuma ƙaƙƙarfan kayan yana ƙayyade yiwuwar ƙirar samfurin.
Bisa ga halaye na masana'antu, 45 karfe da aluminum gami yawanci ana zaba don ƙirar kayan aiki mara kyau;45 karfe da gami karfe ana amfani da more for tooling zane na machining;mafi yawan kayan aikin kayan aiki na masana'antun sarrafa kayan aiki za su zabi aluminum gami.
- 02 Yaya kwanciyar hankali kayan
Don samfurin da ke buƙatar daidaito mai girma, idan bai tsaya tsayin daka ba, nakasu iri-iri zasu faru bayan haɗuwa, ko kuma za'a sake lalacewa yayin amfani.A takaice, yana ci gaba da lalacewa tare da canje-canje a cikin yanayi kamar zazzabi, zafi da girgiza.Ga samfurin, mafarki ne mai ban tsoro.
- 03 Menene aikin sarrafa kayan
Ayyukan aiki na kayan yana nufin ko ɓangaren yana da sauƙin sarrafawa.Ko da yake bakin karfe yana hana tsatsa, bakin karfe ba shi da sauƙin sarrafawa, taurinsa yana da girma, kuma yana da sauƙi a sa kayan aiki yayin sarrafawa.Gudanar da ƙananan ramuka akan bakin karfe, musamman ramukan zaren, yana da sauƙi don karya ƙwanƙwasa da famfo, wanda zai haifar da tsadar sarrafawa.
- 04 Anti-tsatsa magani na kayan
Maganin rigakafin tsatsa yana da alaƙa da kwanciyar hankali da ingancin bayyanar samfur.Misali, karfe 45 yawanci yana zaɓar maganin “blackening” don rigakafin tsatsa, ko fenti da fesa sassan, kuma yana iya amfani da mai mai rufewa ko ruwa mai hana ruwa don kariya yayin amfani bisa ga buƙatun muhalli…
Akwai matakai da yawa na maganin tsatsa, amma idan hanyoyin da ke sama ba su dace ba, to dole ne a maye gurbin kayan aiki, irin su bakin karfe.A kowane hali, matsalar rigakafin tsatsa na samfurin ba za a iya watsi da ita ba.
- 05 Menene farashin kayan
Farashin yana da mahimmancin la'akari a zabar kayan.Alloys ɗin Titanium suna da haske cikin nauyi, tsayin takamaiman ƙarfi, kuma suna da kyau a juriya na lalata.Ana amfani da su ko'ina a cikin tsarin injin mota kuma suna taka rawar da ba za a iya ƙima ba wajen ceton makamashi da rage yawan amfani.
Ko da yake sassan alloy na titanium suna da irin wannan kyakkyawan aiki, babban dalilin da ke hana tartsatsin aikace-aikacen allo na titanium a cikin masana'antar kera shine tsada.Idan ba kwa buƙatarsa da gaske, je neman abu mai rahusa.
