1. U dulqaadashada qasabadaha darajooyinka kala duwan ee saxda ah
Heerka saxda ah ee tuubada lama dooran karo oo la go'aamin karo kaliya iyadoo loo eegayo heerka saxda ah ee dunta lagu farsameeyo, Waa inay sidoo kale tixgelisaa:
(1) Qalabka iyo adkaanta qalabka shaqada ee lagu farsameeyo;
(2) Qalabka tuubada (sida xaaladaha qalabka mashiinka, qalabka wax lagu dhejiyo, giraanta qaboojinta, iwm.);
(3) Saxnaanta iyo khaladka wax soo saarka ee tuubada lafteeda.
Tusaale ahaan: farsamaynta dunta 6H, marka la farsameynayo qaybaha birta, 6H tuubada saxda ah ayaa la dooran karaa;Marka lagu farsameeyo birta cawl cawl, sababtoo ah dhexroorka dhexe ee tuubada ayaa si dhakhso ah u xirta, ballaarinta godka qulqulka ayaa sidoo kale yar, sidaas darteed waxaa habboon in la doorto tuubada saxda ah ee 6HX, noloshu way fiicnaan doontaa.
Sharaxaada saxda ah ee tuubada JIS:
(1) Goynta tuubada OSG waxay isticmaashaa nidaamka saxda ah ee OH, oo ka duwan heerarka ISO, nidaamka saxda ah ee OH wuxuu ku qasbi doonaa ballaca aaga dulqaadka oo dhan xadka ugu hooseeya, 0.02mm kasta sida heerka saxda ah, oo lagu magacaabo OH1, OH2, OH3, iwm. ;
(2) Tuubada Extrusion OSG waxay isticmaashaa nidaamka saxda ah ee RH, nidaamka saxda ah ee RH wuxuu qasbayaa ballaca aagga dulqaadka oo dhan inuu ka bilaabo xadka ugu hooseeya, 0.0127mm kasta sida heerka saxda ah, oo lagu magacaabo RH1, RH2, RH3 iyo wixii la mid ah.
Sidaa darteed, marka la isticmaalayo tuubada saxda ah ee ISO si loogu beddelo tuubada saxda ah ee OH, si fudud looma tixgelin karo in 6H ay la mid tahay heerka OH3 ama OH4, kaas oo u baahan in lagu go'aamiyo beddelaad, ama iyadoo loo eegayo xaaladda dhabta ah ee macaamilka.
2. Cabbirka dibadda ee tuubada
(1) Waqtigan xaadirka ah, kuwa ugu badan ee la isticmaalo waa DIN, ANSI, ISO, JIS, iwm.
(2) Dooro dhererka guud ee ku habboon, dhererka daabka oo xakamee cabbirka labajibbaaran iyadoo loo eegayo shuruudaha habaynta ee kala duwan ama xaaladaha jira ee macaamiisha;
(3) Faragelinta inta lagu jiro howsha.
3. 6-da walxood ee aasaasiga ah ee xulashada tuubada
(1) Nooca farsamaynta dunta, metric, British, American, iwm;
(2) Nooca dunta godka hoose, dalool ama dalool indho la'aan ah;
(3) Qalabka iyo adkaanta qalabka shaqada si loo farsameeyo;
(4) Qoto dheer ee dunta dhamaystiran ee workpiece iyo qoto dheer ee godka hoose;
(5) Saxnimada loo baahan yahay dunta workpiece;
(6) Qaabka heerka tuubada.
