Menene CNC Niƙa?

Injin CNC tsari ne na sarrafa kayan aiki wanda ke cire kayan aiki ta amfani da kayan aikin yankewa masu juyawa.

Ana amfani da cibiyoyin injinan CNC na zamani sosai don:

• Ma'aikata na tushen mold
• Injin rami mai kauri
• Injin kwane-kwane
• Samar da na'urorin lantarki (electrical production)
• Daidaitaccen samar da kayan aiki

Amfanin CNC milling sun haɗa da:

• Babban ƙimar cire kayan
• Saurin injin aiki mai sauri
• Ƙananan farashin aiki
• Kyakkyawan yawan aiki don cire kayan da yawa

Duk da haka, kayan aikin CNC suna da iyaka ta hanyar tsarin halittarsu kuma ba za su iya ƙirƙirar kusurwoyi masu kaifi ko kuma ramuka masu zurfi sosai ba cikin sauƙi.

Menene EDM?

Injin Fitar da Wutar Lantarki(EDM) yana cire kayan ta hanyar tartsatsin wutar lantarki mai sarrafawa tsakanin lantarki da kayan aikin.

Ba kamar niƙa ba, EDM ba ya amfani da ƙarfin yankewa na inji.

Ana amfani da EDM akai-akai don:

• Injin zurfin rami
• Ƙirƙirar kusurwa mai kaifi
• Injin ƙarfe mai tauri
• Cikakkun bayanai game da mold
• Ayyukan kammalawa masu kyau

Saboda babu hulɗa kai tsaye ta kayan aiki, kayan injin na EDM na iya yin aiki ba tare da la'akari da taurin kai ba.

EDM vs CNC Niƙa: Manyan Bambance-bambance

1. Ka'idar Inji

2. Ikon Injin Karfe Mai Tauri

CNC Niƙa

Lalacewar kayan aiki yana ƙaruwa sosai lokacin da ake sarrafa kayan da suka taurare sama da HRC 50-55.

EDM

Taurin kayan ba shi da tasiri sosai kan ƙarfin injin.

Ga ƙarfe mai tauri, EDM yana ba da fa'ida mai mahimmanci.

3. Kusurwoyin Ciki da Tsarin Lissafi Mai Hadaka

Ɗaya daga cikin manyan ƙuntatawa na injin niƙa CNC shine diamita na kayan aiki.

Ko da ƙananan injinan niƙa suna barin radius na kusurwa.

Misali:

• Injin niƙa na CNC ba zai iya samar da kusurwoyi masu kaifi sosai ba.
• EDM na iya sake fasalin siffar lantarki daidai, gami da kusurwoyi masu kaifi da cikakkun bayanai masu rikitarwa.

4. Gudun Inji

Don yin kayan ado masu yawa:

Injin CNC yana da sauri sosai.

Cire babban rami gaba ɗaya tare da EDM ba zai yi tasiri ba kuma zai yi tsada.

Yawancin masana'antun mold suna amfani da injin niƙa CNC da farko sannan daga baya su yi amfani da EDM.

5. Kammalawar Sama

Fasaha ta zamani ta EDM na iya samar da kyakkyawan ƙarewar saman da ya dace da aikace-aikacen mold da yawa.

Fa'idodin sun haɗa da:

• Rage lokacin gogewa
• Inganta daidaiton ramin
• Kula da rubutu mai kyau

Injin niƙa mai sauri kuma yana iya samun kyakkyawan ingancin saman, amma EDM sau da yawa yana ba da sakamako mafi kyau a wuraren da ke da wahalar isa.

6. Sayen Kayan Aiki

Ainihin farashin ya dogara da aikace-aikacen.

7. Injin Kogo Mai Zurfi

Zurfi da kunkuntar ramuka suna haifar da ƙalubale ga kayan aikin niƙa.

Matsalolin sun haɗa da:

• karkatar da kayan aiki
• Girgizawa
• Karyewar kayan aiki

EDM ta yi fice a cikin waɗannan yanayi.

Yaushe Ya Kamata Ka Zaɓar Injin CNC?

Injin CNC yana da kyau idan:

• Dole ne a cire adadi mai yawa na kayan da sauri
• Samar da tushen mold
• Injin buɗe ramuka
• Masana'antar lantarki
• Samun babban yawan aiki

Don ayyukan injina masu wahala, injin niƙa CNC yawanci shine mafita mafi arha.

Yaushe Ya Kamata Ka Zaɓar EDM?

EDM shine mafi kyawun zaɓi lokacin da:

• Injin ƙarfe mai tauri
• Ƙirƙirar ramuka masu zurfi
• Samar da kusurwoyi masu kaifi na ciki
• Cikakkun bayanai game da tsarin mold mai rikitarwa
• Samun kyakkyawan kammala surface

Don kammala ayyukan da kuma fasalulluka masu rikitarwa na mold, EDM sau da yawa yana zama dole.

Wanne Ya Fi Kyau Don Yin Mold?

Amsar ta dogara ne akan aikace-aikacen.

Idan manufar ita ce cire kayan da sauri da kuma yawan aiki mai yawa, injin niƙa CNC shine mafita mafi dacewa.

Idan manufar ita ce ƙera ƙarfe mai tauri, ramuka masu zurfi, siffofi masu rikitarwa, ko cikakkun bayanai na ƙira masu inganci, EDM galibi shine zaɓi mafi kyau.

Ga yawancin ƙwararrun masana'antun mold, mafi kyawun dabarar ba EDM ko CNC niƙa ba ce - tana amfani da fasahohin biyu tare don haɓaka inganci da inganci.

Kammalawa

Injin niƙa na EDM da CNC kowannensu yana taka muhimmiyar rawa a cikin ƙera mold na zamani.

Injin niƙa na CNC yana ba da sauri da inganci ga injinan da ba su da ƙarfi, yayin da EDM ke ba da daidaito da sassauci da ake buƙata don fasalulluka masu rikitarwa na mold.

Fahimtar ƙarfin kowane tsari yana bawa masana'antun damar zaɓar fasahar da ta dace don kowane mataki na samar da mold, wanda ke haifar da inganci mafi kyau, gajerun lokacin jagora, da kuma ƙarancin farashin masana'antu gabaɗaya.
