Momwe Mungasinthire Mabala a Titanium Moyenerera

Mipiringidzo ya Titaniyamu amagwiritsidwa ntchito kwambiri muzamlengalenga, zamankhwala, komanso ntchito zamafakitale apamwamba kwambiri chifukwa cha kuchuluka kwawo kwamphamvu ndi kulemera kwawo komanso kukana dzimbiri. Komabe, kupanga titaniyamu nthawi zambiri kumawoneka ngati kovuta chifukwa cha kutsika kwake kwamafuta, kusinthasintha kwamphamvu kwamankhwala, komanso chizolowezi choumitsa ntchito. Bukuli likufufuza momwe mungasinthire mipiringidzo ya titaniyamu bwino, kuyang'ana pa liwiro lodula, kusankha zida, ndi kugwiritsa ntchito koziziritsira kuti muwongolere magwiridwe antchito ndikukulitsa moyo wa zida.

Chifukwa Chiyani Titanium Ndi Yovuta Kupanga Makina?

Musanadumphire muzochita zabwino, ndikofunikira kumvetsetsa machitidwe a makina a titaniyamu:

• Mafuta ochepa otsika: Titaniyamu imasunga kutentha m'mphepete, zomwe zimatsogolera ku kuvala kwa zida mwachangu.
• Mphamvu yapamwamba pa kutentha kokwera: Imachulukitsa kukana kodula panthawi yogwira ntchito yayitali.
• Ntchito kuumitsa: Titaniyamu imalimbitsa pansi pa kupsinjika kwamakina, kupangitsa kudula kotsatira kukhala kovuta.
• Chemical reactivity: Amakonda kuwotcherera ndi zida zida, makamaka kutentha kwambiri.

Zinthu izi zimafuna kulinganiza mosamalitsa ndondomeko ndi njira zina zogwiritsira ntchito zida.

Sankhani Liwiro Loyenera Kudula ndi Kudya

Kuthamanga Koyenera Kwambiri kwa Titanium Bars:

Chothandizira: Kuthamanga kwapansi ndi kotetezeka kwa roughing. Kuthamanga kwapamwamba kungagwiritsidwe ntchito pomaliza ngati kuziziritsa ndikokongoletsedwa.

Mitengo ya Zakudya:

ntchito zakudya zapakatikati mpaka zapamwamba (0.1-0.3 mm / rev) kuchepetsa kusonkhanitsa kutentha.

Pewani kusisita kapena zinthu zochepa za chakudya zomwe zingayambitse kutha msanga.

Sankhani Zida Zoyenera

Zida Zovomerezeka:

• Zida za Micrograin carbide: Kukhazikika kwabwino kwamphamvu komanso kukana kutentha.
• Zida zokutira (AlTiN, TiAlN, TiCN): Kupirira kutentha kwambiri ndi kuchepetsa anamanga m'mphepete.
• Ma geometries akuthwa: Ma angles abwino ndi m'mphepete mwake amachepetsa mphamvu zodulira.

Malangizo Opangira Zida:

Kutalika kwafupi: Imachepetsa macheza ndi kupatuka.

High chitoliro helix angle: Imawongolera kutuluka kwa chip ndikumaliza pamwamba.

Ma radii apakona kapena chamfers: Chepetsani kusweka kwa nsonga ya chida.

Gwiritsani Ntchito Yoziziritsa Kusefukira kwa Madzi kapena High-Pressure Coolant (HPC)

Kuziziritsa koyenera ndikofunikira pa titaniyamu:

• Madzi ozizira (osachepera 10 malita / min): Imasunga kutentha ndikutsitsa tchipisi.
• Kuzizira kwambiri (70-150 bar): Kuchita bwino kwambiri pobowola dzenje lakuya kapena mphero.
• Gwiritsani ntchito madzi odula osungunuka m'madzi ndi lubricity mkulu kuchepetsa reactivity mankhwala.
• Pewani makina owuma pokhapokha mutagwiritsa ntchito zida zapadera ndi zokutira zomwe zili ndi chidwi chochepa.

Chip Control ndi Machining Strategy

Kusamuka kosauka kwa chip kumatha kuwononga chida komanso chogwirira ntchito. Gwiritsani ntchito:

• Peck kubowola kuthyola tchipisi taliatali m'makina akuya.
• Kukwera mphero osati mphero wamba kuti achepetse kuthamanga kwa zida.
• Mabala osokonezedwa ziyenera kupewedwa ngati n'kotheka, chifukwa zimawonjezera kutenthedwa kwa kutentha.

Yang'anirani Zida Zovala ndi Kugwiritsa Ntchito Njira Zosinthira

Yang'anani zizindikiro za kuvala m'mbali ndi ma notch.

Sungani toolpath optimization software kusintha ma feed ndi liwiro dynamically.

Taganizirani zida zowunikira machitidwe ngati mukugwira ntchito pazida zokha.

Kutsiliza

Kucheka titaniyamu moyenera kumafuna njira yokhazikika yomwe imaganizira za kudula, kuyika zida, kuziziritsa, ndi kutulutsa chip. Ndi njira zoyenera, mungathe onjezerani zokolola, onjezerani moyo wa chidandipo kupeza zomaliza zapamwamba mu makina a titaniyamu.
