Batho ba bangata ba nahana hore machining ke machining feela, le hore likarolo tsa mochini oa kaho o sehiloeng ka letsoho le likarolo tsa mochini li sebelisoa ka mokhoa o ts'oanang. Na li hlile li tšoana joalo? E seng joalo hantle. Ak'u nahane hore na ke hobane'ng ha likarolo tse entsoeng ka mochine tse entsoeng Japane le Jeremane li le tsa boleng bo phahameng. Ntle le lisebelisoa tse tsoetseng pele tsa mochini, li boetse li itšetleha ka litekanyetso le lits'ebetso tse thata. Kajeno, a re qaleng ka mohato oa pele: ho khaola lelakabe.
1.1 Kakaretso ea Ts'ebetso
Ho itšeha ha malakabe ke mohato oa pele oa ts'ebetso ea lisebelisoa tse tala molemong oa tlhahiso ea li-excavator boom le mohato oa pele oa ho lokisa lijana bakeng sa mechini e mengata ea kaho. Sepheo sa eona sa mantlha ke ho arola ka nepo lipoleiti tse kholo tsa tšepe ka likarolo tse fapaneng bakeng sa ho etsoa ka morao, ho kenyeletsoa lipoleiti tse ka ntle tsa maballo, lipoleiti tse matlafatsang ka hare, le lipoleiti tsa litulo tsa trunnion, ho latela litlhoko tsa moralo.
Ts'ebetso ena e sebelisa lisebelisoa tsa CNC tsa ho seha mafura a oksijene, tse hlahisang lelakabe la mocheso o phahameng ka ho sebelisa motsoako oa oksijene-acetylene ho qhibiliha le ho etsa oxidize poleiti ea tšepe ea carbon.
1.2 Tlhophiso ea Sesebelisoa
● Mochini oa ho itšeha oa CNC (benchtop/gantry)
● Mananeo a iketselitseng le sistimi ea ho laola tsela (e ipapisitseng le litšoantšo tsa CAD)
● Sistimi ea phepelo ea khase ea oksijene le acetylene
● Phahamiso ea toche e iketsang le mojule oa taolo ea mocheso oa lelakabe
1.3 Lisebelisoa tsa lisebelisoa
1.4 Ts'ebetso
1) Ho itokisa pele ho khaola
● Hlahloba hore na lisebelisoa le boholo ba poleiti ea tšepe li lumellana le litšoantšo tsa moralo;
● Ntša oli, mongobo le mafome holim'a poleiti ea tšepe.
2) Lenaneo le ho hlophisa
● Kenya meralo ea CAD ho sistimi ea ho itšeha ea CNC;
● Ho haha sehlaha ka bohlale ho ntlafatsa tšebeliso ea lintho tse bonahalang;
● Beha taelo ea ho itšeha, ho etelletsa pele likarolo tse nyenyane ho likarolo tse kholo ho thibela ho senyeha ha mocheso.
3) Ho lokisa lisebelisoa
● Lekanya ho nepahala ha tsela;
● Beha khatello ea khase ea mollo (0.4-0.6 MPa bakeng sa oksijene, 0.01-0.05 MPa bakeng sa acetylene);
● Fetola lekhalo la pele pakeng tsa toche ea ho itšeha le poleiti ea tšepe (3-5 mm).
4) Ts'ebetso ea ho itšeha lelakabe
● Motumo o chesa pele ho moo thepa e tukang;
● Hlooho ea ho itšeha e itsamaela ka tsela e iketsang, ha ho khaola lelakabe ho tsoela pele ka nako e le 'ngoe;
● E boloka bophara ba kerf bo tsitsitseng (hangata 2.5mm ho 4mm) ho thibela ho chesa ho sa tšoaneng.
5) Tlhahlobo ea boleng
● Hlahloba ka mahlo ho otloloha ha sehiloeng le bohloeki ba bokaholimo;
● Sebelisa tekanyo ea botenya ea ultrasonic ho netefatsa botebo ba sebaka se amehileng ke mocheso libakeng tsa bohlokoa;
● Hlahloba ho mamellana ha likarolo tse khaotsoeng (ka kakaretso ≤± 1.5mm).
6) Post-processing
● Tlosa li-burrs tsa ho itšeha ka letsoho;
● Hloekisa sekala sa oxide ho thibela masoba a latelang a ho cheseletsa.
1.5 Lintlha tsa Tekheniki le Litlhokomelo
● Lebelo la ho itšeha le lumellana ka thata le botenya ba poleiti ho thibela sekhahla sa ho itšeha hore se se ke sa oa kapa sa chesa;
● Letlapa la tšepe le tlameha ho tlamisoa ka mokhoa o tsitsitseng ho qoba ho thothomela nakong ea ho seha ho ka bakang ho kheloha tseleng ea ho seha.
● Bakeng sa lipoleiti tse teteaneng tse fetang 40mm, leano la ho futhumatsa lelakabe la mekhahlelo e mengata le lokela ho sebelisoa ho ntlafatsa kerf verticality.
● Boloka bohloeki ba oksijene ea ≥99.5%, ho seng joalo boreleli ba sebaka se sehiloeng se tla ameha.
● Nakong ea tlhahiso, liphetoho tsa mocheso oa lelakabe li lokela ho hlahlojoa ka nako ea sebele ho lokisa tekanyo ea khase hang-hang.
E ka holimo ke mohato oa pele oa ho machining oa baepolli ba mechine ea kaho, ho itšeha lelakabe.
