Ka mashome a lilemo, tšepe e entsoeng ka tšepe e bile mokokotlo oa metheo ea lisebelisoa tsa mochini, liforeimi tsa metrology, le libaka tsa mosebetsi tse nepahetseng.

Empa ha liindasteri li ntse li sutumelletsa lebelo le phahameng la spindle, mamello e thata, le libaka tse hloekileng tsa tlhahiso, mefokolo ea tšepe - katoloso ea mocheso, ho ba kotsing ea ho bola, linako tse telele tsa ho etella pele, le litšenyehelo tse phahameng tsa matla ho lahla - li ntse li thatafalloa ho li hlokomoloha.
Kenya mokhoa o mong o khutsitseng le o bohlale haholoanyane: kopano ea granite ea epoxy, e tsejoang hape e le polymer composite kapa mineral casting. Ho ZHHIMG, re qetile lilemo tse 12 tse fetileng re ntlafatsa theknoloji ena—eseng feela e le sebaka sa tšepe, empa e le sethala se setle sa litsamaiso tsa ho nepahala tsa moloko o latelang. Ka tšebeletso ea rona ea Custom Mineral Casting, re rala le ho hlahisa meaho e kopaneng ka botlalo e kopanyang damping, botsitso ba mocheso, le ts'ebetso e kenelletseng ka litsela tseo li-foundry tsa setso li ke keng tsa li bapisa.
Joale hantle-ntle granite ea epoxy ke eng? Ho sa tsotellehe lebitso leo, ha e na tlhaho.matlapa a granite. Ho ena le hoo, ke thepa e nepahetseng ea ho lahla e entsoeng ka motsoako oa liminerale tse ntle tse fetang 90% (hangata quartz, basalt, kapa lerōle la granite le sebelisitsoeng hape) tse kopantsoeng hammoho ke sistimi ea resin ea epoxy e sebetsang hantle. Sephetho ke motsoako o nang le thepa e ikhethang: ho kolobisa ka hare ho fihlela ho makhetlo a 10 ho feta tšepe e entsoeng ka tšepe, katoloso ea mocheso e batlang e se na letho ha e entsoe hantle, le ho itšireletsa ka botlalo mafome, li-coolant le lik'hemik'hale tse ngata tsa indasteri.
Empa molemo oa 'nete o lutse tokolohong ea moralo. Ho fapana le ho betla ka tšepe—e hlokang likhutlo tsa ho betla, botenya ba lebota bo tšoanang, le ho betla ka mor'a ho kenya likarolo—ho betla ka polymer ho re lumella ho kenya li-rails tse otlolohileng, likanale tsa coolant, li-cable conduit, li-motor mounts, esita le lipokotho tsa sensor ka ho toba mohahong nakong ea ho tšela. Sena se felisa mehato ea ho kopanya, se fokotsa palo ea likarolo, 'me se ntlafatsa haholo botsitso ba ho hokahanya nako e telele.
Moetsi e mong oa Europe oa mechini ea ho lekanya ea optical coordinate o ile a fetohela ho kopano ea granite ea epoxy ea ZHHIMG bakeng sa foreimi ea bona ea motheo 'me a bona lerata la tekanyo le bakoang ke ho thothomela le theoha ka 73%. "Ho pheta-pheta ha rona ho ile ha fokotsoa ke li-micro-resonances tse ka har'a tšepe e entsoeng ka tšepe," ho hlalositse moenjiniere oa bona ea ka sehloohong. "Ka ho lahla liminerale, maqhubu ao a monngoa pele a fihla probe."
Ho ZHHIMG, ha re nke ho lahla diminerale ka mokhoa o ikgethang e le tshebetso ya thepa. Sebopeho se seng le se seng se etseditswe tshebediso. Na o hloka ho damping e phahameng ka ho fetisisa bakeng sa spindle ya ho sila e lebelo le hodimo? Re ntlafatsa kabo ya boholo ba dikarolwana le viscosity ya resin ho eketsa kgohlano ya ka hare. Na o hloka ho ntsha kgase e tlase haholo bakeng sa roboto e sebetsanang le semiconductor? Re sebedisa ditsamaiso tsa epoxy tse ntshwang ka vacuum-gassing, tse nang le VOC e tlase tse netefaditsweng bakeng sa diphaposi tsa ho hlwekisa tsa ISO Class 5. Na o rera borokho ba metrology bo lokelang ho tshwara ho lekana ka nako ya dipotoloho tsa mocheso wa dihora tse 24? Re kenyelletsa di-filler tse nang le katoloso e tlase le diprothokhole tsa ho fokotsa kgatello ya maikutlo.
Boemo bona ba taolo bo hlaha mokgweng wa rona o kopaneng ka ho otloloha. Re iketsetsa metswako ya rona ya resin, re fumana le ho sefa di-aggregates tsa rona ho fihlela di lekana le maemo a micron, mme re lokisa dikarolo tlasa diprofayili tsa mocheso le mongobo tse laolwang. Kamora ho fola, ho lahla ho nepahetseng ho feta netefatsong ya dibopeho ka laser tracker kapa photogrammetry—ho netefatsa hore di-data tse bohlokwa di tshwarelwa ho ±10 µm ho feta dimithara tse 2, esita le hodima dijiometri tse rarahaneng tsa 3D.
Kaha epoxy granite e folisa mochesong oa kamore, ha ho na khatello e setseng e bakoang ke ho fokotseha ha ho pholisa—e leng sesosa se tloaelehileng sa ho kheloha ha nako e telele linthong tse entsoeng ka tšepe. Sebopeho seo u se kenyang kajeno ke sebopeho seo u tla ba le sona lilemong tse leshome tse tlang.
Mohlomong molemo o matla ka ho fetisisa ke lebelo. Motheo oa tšepe ea setso o ka nka libeke tse 12-16 ho tloha ho etseng lipaterone ho isa ho machining ea ho qetela. Ka motsoako oa polymer, ZHHIMG e fana ka li-prototype tse sebetsang ka botlalo ka libeke tse 3 feela le li-unit tsa tlhahiso ka 5-6. Qalo e 'ngoe e thehiloeng US e hlahisang lepolanka le lenyenyane la CNC bakeng sa li-implant tsa meno e fokotsa nako ea bona ea ho ea 'marakeng ka likhoeli tse' ne feela ka ho fetohela kopanong ea rona ea granite ea epoxy - e ba lumellang ho fumana tumello ea FDA ka pele ho bahlolisani.
Phokotso ea litšenyehelo e latela ka tlhaho. Le hoja litšenyehelo tsa thepa e tala ka kilogram li ka bapisoa, ho felisoa ha mesebetsi ea bobeli—ho imolla khatello ea maikutlo, ho penta, ho sebetsa ka thata—ho fokotsa litšenyehelo tsohle tsa ho fihla ka 20–35% maemong a mangata. Eketsa boima bo tlase ba ho romela thepa (granite ea epoxy e bobebe ho feta tšepe e entsoeng ka tšepe) 'me u fokotse litlhoko tsa motheo,' me nyeoe ea khoebo e hlaka.
Netefatso ea indasteri e ntse e hola. Tlalehong ea Lefatše ea Lisebelisoa tsa Mechini ea 2025, ZHHIMG e ne e behiloe har'a bafani ba bararo ba kaholimo lefatšeng ka bophara bakeng sa ho Hlahisa Liminerale ka Mokhoa o Ikhethileng, e tsebahalang ka "botšepehi bo ikhethang ba jeometri le bokhoni ba ho pheta-pheta ka potlako." Empa ho hong ho totobatsang botšepehi ba bareki ke: ho feta 80% ea merero ea rona ea ho lahla polymer e lebisa ho liodara tse pheta-phetoang kapa katoloso ea sethala.
Re hahile ntho e 'ngoe le e 'ngoe ho tloha ho liforeimi tsa CMM tsa lithane tse 8 tse nang le libaka tse kopantsoeng tse jereng moea ho ea ho li-stand tsa calibration tse nkehang habobebe bakeng sa liroboto tsa tšebeletso ea tšimo.

Kahoo ha o ntse o rera ntlafatso e latelang ya moralo wa mochini kapa metrology, ipotse: Na ke thibetswe ke meedi ya tshepe—kapa ke matlafatswa ke menyetla ya ho kopanya?
Haeba karabo ea hau e sekametse boqaping, botsitso le lebelo, e kanna ea ba nako ea ho batlisisa seo ho lahla ka nepo ka motsoako o tsoetseng pele oa polymer ho ka se etsang. Ho ZHHIMG, ha re tšele granite ea epoxy feela—re etsa boenjiniere ba ts'ebetso ka har'a karoloana e 'ngoe le e 'ngoe.
