Mokhoa oa ho Theha Li-bar tsa Titanium ka nepo

Libaka tsa Titanium li sebelisoa haholo sebakeng sa lifofane, tsa bongaka, le lits'ebetso tse phahameng tsa indasteri ka lebaka la karo-karolelano ea tsona e ntle ea boima ba 'mele le ho hanyetsa ho bola. Leha ho le joalo, ho etsa machining titanium hangata ho nkoa e le phephetso ka lebaka la mocheso o tlase oa mocheso, lik'hemik'hale tse phahameng tsa lik'hemik'hale, le tšekamelo ea ho thatafatsa mosebetsi. Tataiso ena ea hlahloba mokhoa oa ho kenya li-bar tsa titanium ka katleho, e shebaneng le lebelo la ho itšeha, khetho ea lisebelisoa, le ts'ebeliso ea pholiso ho ntlafatsa ts'ebetso le ho lelefatsa bophelo ba lisebelisoa.

Hobaneng ha Titanium e le Thata ho Mochini?

Pele o kenella mekhoeng e metle, ho bohlokoa ho utloisisa boits'oaro ba machining ba titanium:

• Bohloela bo tlase ba mafura: Titanium e boloka mocheso moeling oa ho itšeha, e lebisang ho ho roala lisebelisoa ka potlako.
• Matla a phahameng mochesong o phahameng: E eketsa khanyetso ea ho itšeha nakong ea ts'ebetso ea nako e telele.
• Sebetsa ka thata: Titanium e matlafatsa tlas'a khatello ea mochine, e etsa hore ho fokotsa ho latelang ho be thata le ho feta.
• Reactivity ea lik'hemik'hale: E rata ho cheseletsa ka lisebelisoa tsa lisebelisoa, haholo-holo tlas'a mocheso o phahameng.

Lintlha tsena li hloka moralo o hlokolosi oa ts'ebetso le maano a khethehileng a lisebelisoa.

Khetha lebelo le nepahetseng la ho itšeha le sekhahla sa phepelo

Mabelo a nepahetseng a ho Seha bakeng sa Libara tsa Titanium:

Pro Tip: Mabelo a tlase a bolokehile bakeng sa ho khoasolla. Mabelo a holimo a ka sebelisoa ho phethela haeba ho pholile ho ntlafalitsoe.

Litefiso tsa Lijo:

tshebediso sekgahla se mahareng ho isa ho se phahameng (0.1-0.3 mm / rev) ho fokotsa ho bokella mocheso.

Qoba ho hohla kapa maemo a phepo e tlase a ka lebisang ho apara ka potlako.

Khetha Sesebelisoa se nepahetseng

Lisebelisuoa tse khothalelitsoeng:

• Lisebelisoa tsa Micrograin carbide: Molemo ka ho fetisisa ho leka-lekana ha boima le ho hanyetsa mocheso.
• Lisebelisoa tse koahetsoeng (AlTiN, TiAlN, TiCN): E mamella mocheso o phahameng le ho fokotsa moeli o hahiloeng.
• Li-geometri tse bohale: Li-angles tse ntle tsa rake le lithako tse honed li fokotsa matla a ho itšeha.

Malebela a Moralo oa Lisebelisoa:

Pherekano e khutšoane: E fokotsa moqoqo le ho kheloha.

Lekolilo le phahameng la helix angle: E ntlafatsa ho ntšoa ha chip le ho qeta bokaholimo.

Corner radii kapa chamfers: Fokotsa ho robeha ha lisebelisoa tsa lisebelisoa.

Sebelisa Sepholiso sa Moroallo kapa Sepholiso se Phahameng ka Ho Fetisisa (HPC)

Pholiso e sebetsang e bohlokoa bakeng sa titanium:

• Pholiso ea likhohola (bonyane lilithara tse 10 ka mets): E boloka mocheso o le tlase le ho hlakola li-chips.
• Sepholi sa khatello e phahameng (70–150 bar): E sebetsa ka ho khetheha ho cheka sekoti se tebileng kapa ho siloa ha slot.
• Sebelisa maro a sehang a qhibilihang ka metsing e nang le lubricity e phahameng ho fokotsa ts'ebetso ea lik'hemik'hale.
• Qoba machining a omileng ntle le haeba o sebelisa lisebelisoa tse khethehileng le liphahlo tse nang le boitlamo bo fokolang.

Taolo ea Chip le Leano la Machining

Ho tlosoa ha chip ho ka senya lisebelisoa le sesebelisoa sa mosebetsi. Sebelisa:

• Ho phunya peck ho pshatla maqheka a malelele ka machining a lesoba le tebileng.
• Hloa ho sila ho ena le ho sila ho tlwaelehileng ho fokotsa kgatello ya disebediswa.
• Maqeba a sitisang li lokela ho qojoa ha ho khoneha, kaha li eketsa ho tšoha ha mocheso.

Lekola Tool Wear le ho Sebelisa Maano a Adaptive

Sheba mats'oao a ho roala ha flank le ho roala ha li-notch.

Qetella software ea ho ntlafatsa lisebelisoa ho lokisa diphepelo le mabelo ka matla.

Nahana lisebelisoa tsa ho hlahloba bophelo ba lisebelisoa haeba e sebetsa ho li-setups tse ikemetseng.

fihlela qeto e

Ho lokisa mekoallo ea titanium ka katleho ho hloka mokhoa o leka-lekaneng o nahanang ka maemo a ho itšeha, lisebelisoa, ho pholisa, le ho tlosoa ha chip. Ka mekhoa e nepahetseng, u ka khona ntlafatsa tlhahiso, lelefatsa bophelo ba lisebelisoa, 'me finyella maemo a holimo holimo ka machining a titanium.
