Mokhoa oa ho Khetha Lisebelisoa tse Nepahetseng tsa ho Seha Taemane

Ha ho tluoa tabeng ea ho fihlela ts'ebetso e phahameng ea ho sebetsa ka machining, khetho ea lisebelisoa tsa ho seha taemane e bohlokoa haholo. Litaemane tse le 'ngoe tsa kristale, PCD (kapa PCD/CC), le litaemane tsa CVD ke lisebelisoa tse etellang pele bakeng sa ho etsa lisebelisoa tsa ho seha tse kang lisebelisoa tsa ho reteleha, lisebelisoa tse bolang, likotoana tsa ho phunya, li-reamers, li-milling cutters, lisebelisoa tsa ho etsa profiling, le li-saw blades. Ho khetha thepa e nepahetseng ea taemane hoa hlokahala, eseng feela bakeng sa ho fihlela litlhaloso tsa tekheniki empa hape le bakeng sa ho netefatsa hore moruo o sebetsa hantle le botsitso ba tikoloho.

Hobaneng o lokela ho kgetha thepa ya PCD le PCD/CC?

PCD le PCD/CC ke thepa ea taemane e tsebahalang haholo tlhahisong ea sejoale-joale, e tsebahalang ka ho tenyetseha ha eona ho ikhethang. Lisebelisoa tsena ha li felle feela lits'ebetsong tsa setso tsa ho sebetsa ka mechine; li sebelisoa haholo liindastering tse kang likoloi, lifofane, literene tse lebelo le phahameng, peterole, lik'hemik'hale, kaho le ho betla mapolanka. Mafapheng a likoloi le lithuthuthu, PCD le PCD/CC lia ipabola ho sebetsa ka likarolo tse nang le lintho tse ngata tse hohelang, ho kenyeletsoa le li-skirt tsa piston tsa alloy ea aluminium, masoba a li-pin, li-block tsa cylinder, li-gearbox le li-carburetor. Likarolo tsena hangata li na le metsoako ea aluminium matrix e nang le litaba tse phahameng tsa silicon (Si > 12%), moo likaroloana tse thata (joalo ka SiC) li bakang liphephetso tse kholo tsa ho robeha. Lisebelisoa tsa carbide tsa setso li loantšana le lisebelisoa tsena tse boima, tse fellang ka bophelo bo bokhutšoanyane ba lisebelisoa le litšenyehelo tse eketsehileng tsa tlhahiso.

Tshebetso e Phahameng ka ho Fetisisa le Lisebelisoa tsa PCD

Ho sebedisa disebediswa tsa PCD (kapa PCD/CC) bakeng sa ho sebetsa ka faeba ya khabone le polasetiki e matlafaditsweng ya fiberglass (FRP) ho fana ka melemo e babatsehang: di-chip di fokotswa ho ba phofo, mocheso wa ho seha o dula o le tlase, mme bolelele ba ho seha bo kgahla ka makgetlo a leshome ho feta disebediswa tsa carbide tsa K-class, ka sekgahla sa ho tsofala se ka tlase ho karolo ya boraro ya disebediswa tse tshwanang le tsa carbide. Disebediswa tsa PCD le tsona di loketse ho sebetsa ka di-alloy tse thata tse sintilweng esale pele le thepa e sa senyeheng ya tshepe jwalo ka ceramics, rabara, graphite, khalase le patsi e tshwarellang.

Tshebetso ea lisebelisoa tsa PCD e susumetsoa ke ts'ebeliso ea tsona le ts'ebetso e ikhethileng ea ho sebetsa. Ho khetha sehlopha se loketseng le boholo ba likaroloana ho bohlokoa bakeng sa liphetho tse ntle ka ho fetisisa. Boreas e fana ka mefuta e fapaneng ea Li-blades tsa PCD, ho kenyeletsoa LTM2200, LTM004, LTM10, le LTM90, ka boholo ba lithollo bo tloaelehileng ba 1μm (bo botle), 4μm/10μm (bo mahareng), le 25μm (bo kobehileng). Boholo ba lithollo tse kholo bo eketsa ho hanyetsa ho tsofala le ho eketsa bophelo ba lisebelisoa, empa bo ka lebisa ho bohale bo boima. Lithollo tse mahareng li sebetsa e le likhetho tse feto-fetohang bakeng sa ho sebetsa ka kakaretso, ha lisebelisoa tse nang le lithollo tse ntle li fana ka boleng bo botle ba bokaholimo ka lebaka la mahlaseli a tsona a manyenyane a bohale.

Ka Boreas, o ka lebella theknoloji e tsoetseng pele le ditharollo tse ikgethileng tse etseditsweng ditlhoko tsa hao tse ikgethileng tsa ho sebetsa ka mechine. Re ntlafatsa thepa ya rona ya PCD ka dinako tsohle, re fana ka boholo ba dithollo ho tloha ho 2-30μm, re netefatsa hore o fumana disebediswa tse ntle ka ho fetisisa bakeng sa dikopo tsa hao. Kgetha Boreas bakeng sa boleng bo sa bapisweng le tshebetso disebedisweng tsa ho seha taemane, mme o phahamise bokgoni ba hao ba ho sebetsa ka mechine ho ya bophahamong bo botjha!
