Nan ne mafi yawan kurakuran daidaitawa ke faruwa. Saurin RPM ba koyaushe yake taimakawa ba; ciyarwa a hankali ba koyaushe yake mafi kyau ba.

Ciyarwa da Jinkiri sosai = Tarin Zafi Taurin kai

Ciyarwa a hankali yana nufin kayan aikin ya daɗe a wuri ɗaya. Zafi yana taruwa a cikin ƙananan ramuka. Zirconia da aka riga aka yi wa siminti yana shanye zafi kuma ya zama mai rauni. Yumbu yana yagewa maimakon a yanke shi da tsabta.

Alama: Gefuna suna kama da sun tsage kuma sun yi kauri—kamar an tsage su, ba a yanke su ba. Na'urar hangen nesa tana nuna layukan tsagewa marasa tsari, ba wuraren da aka yanke ba.

Ciyarwa da Sauri = Ƙwayoyin Ƙaruwar Damuwa

Ciyar da sauri yana haifar da raguwar ƙarfin aiki. Ko da ƙarfin RPM mai girma ba zai iya daidaita ƙarar ba. Damuwar gefen yana ta'azzara; karyewar yumbu a cikin ƙananan tazara na yau da kullun.

Alama: Ƙananan ramuka na yau da kullun a gefen - kamar tsarin haƙoran gear.

Haɗin Cin Nasara: Babban RPM + Matsakaicin Ciyarwa

• Babban gudun sanda (50,000–60,000 RPM): Yankewa mai santsi, yaɗuwa da ƙarfi daidai gwargwado, ƙarancin tarin zafi
• Matsakaicin abinci: Daidaitacce—ya isa ya hana zafi, ba wai yana haifar da ƙara ba

Sakamako: gefuna suna fuskantar matsin lamba mai ƙarfi, iri ɗaya, da kuma sarrafawa. Yankan yumbu a hankali.

5. Idan gefuna suna da ƙananan ramuka (alamar ƙaruwar damuwa) → rage ciyarwa (rage da 10-20%)
6. Maimaita tare da ƙananan gyare-gyare—nemo yankinku (yawanci yana ɗaukar gwaje-gwaje 3-5)

Kwatanta: Kuskure vs Dama

Shawara ta Ƙwararre: Yi Amfani da Kunnuwanka

Ka manta da lambobin na ɗan lokaci. Saurari sautin yankewa:

• Daidai: Sautin "whoosh" mai laushi, injin yana nan a tsaye, babu wani girgiza a bayyane
• Ciyar da sauri sosai: Sautin "zzzt", zaku iya jin girgiza injin
• Ciyar da abinci a hankali sosai: Sautin "zhhhhh" mara daɗi, wurin yankewa na iya fitar da hayaki (alamar tarin zafi)

Daƙiƙa uku na bugun sauraro suna kallon lamba na tsawon mintuna. Kunnuwanku suna gaya muku abin da ainihin sigogin suke yi.

Shawara ta 4: Dabarun Sanyaya Iska—Matsayin da Matsi ke da Shi

DN-D5Z injin yanke busasshe ne. Zirconia da aka riga aka yi sintering yana da ramuka kuma yana sha ruwan sanyaya, yana shafar raguwar sintering da kuma dacewa. Magani: Sanyaya iska mai fashewa. Amma yawancin mutane suna fahimtar hakan ba daidai ba.

Me yasa Zirconia da aka riga aka yi wa ado da shi yana da zafi cikin sauƙi

Yawan da aka riga aka narkar da shi ƙasa ne; ƙananan ramuka suna da yawa. Zafin niƙa yana makale a cikin waɗannan ramukan—ba zai iya fita ba. Zafin wurin zai iya ƙaruwa 100°C+ cikin minti ɗaya. Zafi = karyewa; karyewa = karyewa. Wannan shine zagayowar.

Kurakurai Uku da Aka Yi a Iska

❌ Kuskure na 1: Busawa a kan tarin guntu

Kana tsammanin kana share guntun ta hanyar hura tururin. Madadin haka, guntun za su sake busawa cikin guntun—suna karce su sake yanke gefuna. Guntun zai ƙara muni.

❌ Kuskure na 2: Hura iska a saman ɓangaren, ba wurin yankewa ba

Kana hura saman da aka gama da tunanin zai sanyaya ɓangaren. Amma tushen zafi shine wurin da kayan aiki-zirconia ke haɗuwa, ba saman ba. Matsin iska da aka ɓata; zafi har yanzu yana ƙaruwa.

❌ Kuskure na 3: Matsin iska ya yi yawa

Tunanin ƙarin matsin lamba = sanyaya jiki. A zahiri, matsin lamba mai yawa yana ɓatar da ƙarfin da ke wurin yankewa, yana ƙara damuwa da yankewa da kuma ƙara ta'azzara ɓarnar.

✅ Daidaitaccen Saitin Iska Mai Fashewa

• Matsayi: Bindiga mai linzami da aka yi niyya zuwa wurin yankewa (yankin tuntuɓar kayan aiki-zirconia)
• Kusurwa: 45°–60° (ba a daidaita ba)
• Tasiri: Iska mai sanyi tana ɗauke da zafi; ana fitar da guntu daga yankin da aka yanke
• Matsi: 0.5–1.0 bar (tsarin DN-D5Z na yau da kullun). Ƙara a hankali har sai guntun sun bushe sosai—sannan a tsaya

Yadda Ake Daidaita Matsayin Iska Mai Fashewa

1. Kalli inda kwakwalwan kwakwa ke tashi yayin yankewa
2. Idan guntun ya tsaya kusa da wurin yankewa ko kuma ya ja da baya → daidaita matsayin iska don ya kai ga wurin yankewa kai tsaye
3. Ƙara matsin lamba na iska har sai an fitar da guntu (a lura da ido)
4. Niƙa wani yanki na gwaji; kwatanta guntu da tushe

Mun ga masu amfani suna gyara matsayin fashewar iska su kaɗai kuma suna kallon raguwar girgiza daga 10% zuwa 5%—ba tare da taɓa wani siga ba.

An riga an yi wa Sintered vs. Sintered: Ba a iya musanyawa ba

• An riga an narkar da shi: Yana da ramuka, yana shan zafi, dole ne a yi amfani da sanyaya iska
• Cikakke a cikin niƙa: Mai yawa, yana zubar da zafi da sauri, fashewar iska ba ta da mahimmanci

Muhimmi: Ba za a iya musanya sigogin zirconia da aka riga aka yi wa siminti da kuma wanda aka yi wa siminti da shi gaba ɗaya ba. Idan ka canza kayan, sake gwadawa.

Shawara ta 5: Jerin Abubuwan Duba Inji—Lokacin da Sigogi Ba Su Ne Matsala Ba

An gyara sigogi na tsawon kwanaki amma cizon guntu ya ci gaba? Matsalar na iya kasancewa injin da kansa, ba saitunan ku ba.

Dubawa ta 1: Yanayin Kayan aiki

Ci gaban lalacewar kayan aiki:

• Sabon kayan aiki: Gefuna masu kaifi, yankewa mai ƙarfi, mai saurin fashewa (yana buƙatar karyewa: guda 5-10)
• Sawa mai sauƙi (mafi kyau): Ana samun ƙananan lalacewa, ƙarfin yankewa da kuma kammala saman duka suna da kyau
• Gaji: rauni mai rauni, ƙarfin yankewa mai ƙarfi, da kuma guntun da ba makawa

Aiki: Duba kayan aiki a kowane yanki 20-30 da na'urar ƙara girman 10×. Nemi hasken gefen. Gefen mara kyau = lokacin maye gurbinsa.

Shawarar Rufi: Ga kayan aikin da aka riga aka yi wa siminti, kayan aikin da aka shafa (TiN, TiAlN) sun fi kyau ba tare da an shafa musu ba da kashi 20-30%. Jarin da aka zuba zai yi tasiri wajen rage guntun.

Dubawa ta 2: Gudun Dogon Dogo

Wannan shine babban dalilin da yasa ba a kula da chipping ba.

Yadda ake aunawa: Haɗa alamar bugun kira zuwa ƙarshen gaban sandar. Juya da hannu. Kalli motsin allura.

Daidaitacce (DN-D5Z): ±0.01 mm matsakaicin gudu

Idan ƙarfin ya yi ƙasa > ±0.02 mm: Ƙafafun yana buƙatar gyara. Hanyar kayan aiki tana girgiza; har ma da cikakkun sigogi suna haifar da guntuwar da ba a sarrafa ba.

Duba mita: Yawan amfani (awanni 8+ a rana) → mako-mako. Amfani na yau da kullun → kowane wata.

Dubawa ta 3: Daidaiton Matsewa na Sashe

Zirconia da aka riga aka yi wa siminti yana da rauni. Duk wani girgiza yana haifar da guntu.

Cak:

• Shin tubalin yana yin birgima gefe da gefe a cikin maƙallin C? (Ya kamata ya zama mai ƙarfi da dutse)
• Shin ƙarfin matsewa ya daidaita? (Ba ya matsewa sosai - yana fasa tubalin; ba ya sassautawa sosai - yana girgiza)
• Shin maƙallin yana riƙe da wani ɓangare mai kauri, ko kuma siririn yanki mai rauni? (Maƙallin kawai sassa masu ƙarfi)

Alamar rashin mannewa: Cirewar guntu yana faruwa a wuri ɗaya a kowane toshe (inda toshen ke lankwasawa).

Dubawa ta 4: Ƙarfin Sanda da Saurin Lokaci na Ainihin

Matsakaicin ƙarfin DN-D5Z: 800W. Ci gaba da ƙarfi: 500W.

Matsalar da aka saba fuskanta: Kun saita 60,000 RPM, amma na'urar ta ragu zuwa 45,000 RPM a ƙarƙashin kaya. Me yasa?

• Sigogi da ƙarfin injin ba su daidaita ba (ciyar da sauri sosai don ƙarfin juyawa)
• Kayan aiki yana da duhu (yana buƙatar ƙarin ƙarfi don yankewa)

Duba: Duba nuni ko manhajar DN-D5Z. Shin saurin spindle na ainihin lokaci ya dace da abin da kake so? Idan ya kan faɗi akai-akai, ko dai a daidaita sigogi ko a maye gurbin kayan aikin.

Me yasa kashi 70% na Chipping Sigogi ne; kashi 30% na Inji ne

Daga cikin gazawar guntuwar da muka yi nazari a kai: kashi 70% sun fito ne daga zaɓin sigogi marasa kyau (dabaru, gudu, ciyarwa, fashewar iska). Kashi 30% ne kawai suka fito daga yanayin injin (lalacewar kayan aiki, runout na spindle, clamping). Don haka gyara sigogi da farko. Idan kun yi nasarar Tip 1-4 kuma har yanzu kuna da guntuwar, to ku duba injin.

Bayani Mai Sauri Game da Alamomin Chipping

Yi amfani da wannan tebur don gano guntuwar da kuma fifita gyare-gyare:

Yadda Ake Amfani da Waɗannan Nasihu 5 a Tsarin Daki

Idan kuna fuskantar chipping a yanzu, bi wannan tsari:

1. Mataki na 1: Yankewa mai layuka uku (Shawara ta 1) → Duba CAM don yin laushi → kammalawa na rabin-kammala → kammala wucewa. Yana magance ~40% na guntu.
2. Mataki na 2: Shigar/Fita daga kayan aiki (Shawara ta 2) → Tabbatar da cewa Ja-in-shiga/Fita daga kayan aiki suna da ramuka, ba ramuka ba. Yana warware ~20%.
3. Mataki na 3: Sauri da ciyarwa (Shawara ta 3) → Duba teburin alamun, daidaita RPM ko ciyarwa. Yana warware ~20%.
4. Mataki na 4: Matsayin fashewar iska (Shawara ta 4) → Yi niyya a kan yanke, kusurwar 45°–60°, matsin lamba na sandunan 0.5–1.0. Yana warware sauran ~10%.
