Ho Beakanya Litšenyehelo tsa Precision—Granite vs. Cast Iron vs. Ceramic Platforms

Phephetso ea Litšenyehelo tsa Material in Ultra-Precision Manufacturing

Ha u batla motheo oa lisebelisoa tsa bohlokoa tsa metrology, khetho ea thepa - Granite, Cast Iron, kapa Precision Ceramic - e kenyelletsa ho leka-lekanya matsete a pele khahlanong le ts'ebetso ea nako e telele le botsitso. Le ha baenjiniere ba etelletsa pele botsitso le thepa ea mocheso, lihlopha tse rekang thepa li shebane le litšenyehelo tsa Bill of Materials (BOM).

Ho ZHHIMG®, re utloisisa hore tlhahlobo e felletseng ea thepa ha ea lokela ho ameha feela ka litšenyehelo tse tala empa hape le ho rarahana ha tlhahiso, botsitso bo hlokahalang, le tlhokomelo ea nako e telele. Ho ipapisitsoe le li-average tsa indasteri le ho rarahana ha tlhahiso bakeng sa lipolanete tse boholo bo tšoanang, tse nepahetseng haholo, tsa boemo ba metrology, re ka theha boemo ba litšenyehelo bo hlakileng.

Tsamaiso ea Theko ea Li-Platform tsa Precision

Bakeng sa sethala se entsoeng ho ea ho maemo a holimo a metrology (mohlala, DIN 876 Grade 00 kapa ASME AA), maemo a tloaelehileng a litheko, ho tloha ho Tlase ho ea ho Litšenyehelo tse Phahameng ka ho Fetisisa, ke:

1. Li-Platforms tsa Ts'epi (Litšenyehelo tsa Qalo tse Tlase)

Cast Iron e fana ka theko e tlase ka ho fetisisa ea thepa ea pele le ea tlhahiso bakeng sa sebopeho sa motheo. Matla a eona a ka sehloohong ke ho tiea ha eona ho phahameng le boiketlo ba ho kenyelletsa likarolo tse rarahaneng (likhopo, li-voids tse ka hare) nakong ea ho lahla.

• Bakhanni ba Litšenyehelo: Thepa e tala e batlang e le theko e tlaase (tšepe, likotoana tsa tšepe) le mekhoa ea ho etsa lilemo tse mashome.
• The Trade-off: Bofokoli bo boholo ba cast iron ho ultra-precision ke ho ba le monyetla oa ho rusa / ho bola le tlhoko ea eona ea ho tsitsisa mocheso (phekolo ea mocheso) ho imolla khatello ea maikutlo ka hare, e leng se eketsang litšenyehelo. Ho feta moo, Coefficient ea eona e phahameng ea Thermal Expansion (CTE) e etsa hore e se tšoanelehe ho feta granite bakeng sa tikoloho e nepahetseng haholo e nang le ho fetoha ha mocheso.

2. Li-Platform tsa Granite tse nepahetseng (Moeta-pele oa Bohlokoa)

Precision Granite, haholo-holo lisebelisoa tse phahameng haholo tse kang 3100 kg/m3 ZHHIMG® Black Granite ea rona, hangata e lula bohareng ba mefuta ea theko, e fana ka tekanyo e ntle ka ho fetisisa ea ts'ebetso le ho khoneha.

• Bakhanni ba Litšenyehelo: Le hoja ho chekoa ha thepa e tala le khetho ea thepa e laoloa, litšenyehelo tse ka sehloohong li itšetlehile ka mokhoa o liehang, o tsitsitseng, oa mekhahlelo e mengata-ho kenyeletsoa sebopeho se thata, botsofali ba tlhaho ba nako e telele bakeng sa ho imolla khatello ea kelello, le mokhoa o boima oa ho qetela o nang le tsebo ea ho qetela ho finyella nanometer flatness.
• Tlhahiso ea Bohlokoa: Granite ka tlhaho ha e na makenete, ha e ruruhe, 'me e na le CTE e tlase le ho thothomela ho holimo. Litsenyehelo li na le mabaka a utloahalang hobane granite e fana ka setifikeiti, botsitso ba nako e telele ntle le tlhokahalo ea phekolo e theko e boima ea mocheso kapa liphahlo tse thibelang ho bola. Sena se etsa hore granite e be khetho ea kamehla bakeng sa boholo ba lits'ebetso tsa sejoale-joale tsa metrology le semiconductor.

3. Li-Platform tsa Ceramic tse nepahetseng (Litšenyehelo tse Phahameng ka ho Fetisisa)

Precision Ceramic (hangata Aluminium Oxide ea boleng bo holimo kapa Silicon Carbide) hangata ke eona e laolang theko e phahameng ka ho fetisisa 'marakeng. Sena se bonahatsa ts'ebetso e rarahaneng ea lihlahisoa tse tala le ts'ebetso ea tlhahiso ea matla a phahameng.

• Bakhanni ba Litšenyehelo: Thepa ea motsoako e hloka bohloeki bo feteletseng le sintering e phahameng ea mocheso, 'me mekhoa ea ho qeta (taemane e sila) e thata ebile e theko e boima.
• The Niche: Ceramics e sebelisoa ha karo-karolelano ea ho satalla ho isa ho boima bo feteletseng 'me ho hlokahala CTE e tlase ka ho fetesisa, joalo ka methating e phahameng ea lebelo la enjene kapa tikolohong ea vacuum. Le ha e phahame ho metriki e meng ea tekheniki, litšenyehelo tse phahameng haholo li fokotsa ts'ebeliso ea eona ho lits'ebetso tse ikhethang haholo, moo tekanyetso e tlang ho latela ts'ebetso.

Qetello: Ho Beha Boleng ba Bohlokoa Pele Ho Feta Theko e Tlase

Ho khetha sethala se nepahetseng ke qeto ea boleng ba boenjiniere, eseng feela theko ea pele.

Leha Cast Iron e fana ka sebaka se tlase haholo sa ho kena, e kenya litšenyehelo tse patiloeng mathateng a botsitso ba mocheso le tlhokomelo. Precision Ceramic e fana ka ts'ebetso e phahameng ka ho fetisisa ea tekheniki empa e hloka boitlamo bo boholo ba lichelete.

Precision Granite e ntse e le 'mampoli oa boleng. E fana ka botsitso ba tlhaho, thepa e phahameng ea mocheso ho lahla tšepe, le bophelo bo bolelele bo se nang tlhokomelo, kaofela ka litšenyehelo tse ka tlase ho tsa ceramic. Boitlamo ba ZHHIMG® mabapi le boleng bo netefalitsoeng, bo tšehelitsoeng ke Litifikeiti tsa rona tsa Quad le metrology e ka lateloang, bo netefatsa hore matsete a hau sethaleng sa granite ke qeto e nepahetseng ka ho fetisisa moruong bakeng sa ho nepahala ho hoholo.
