Qhov zoo ntawm precision castings yog soj ntsuam raws li hauv qab no:
1. Lub nto roughness ntawm castings yuav tsum ua raws li cov kev cai ntawm gb6060.1 casting nto roughness piv piv txwv block.
2. Qhov saum npoo ntawm castings yuav polished yuav tsum ua raws li gb6060.4.
3. Lub casting yuav tsum tau tua blasted, thiab nto ua tiav los ntawm cov xuab zeb blasting yuav tsum tau raws li gb6060.5.
4. Lub casting tsis raug tso cai kom muaj cov kab nrib pleb, nyob rau hauv casting, porosity, npuas thiab tej yam tsis xws luag.
5. Castings tsis pub muaj qhov tsis xws luag xws li khawb, kev nyuaj siab, tsis muaj nqaij, mesh burr thiab isosceles daim duab peb sab.
6. Lub rooj vag, flash, overflow chaw nres nkoj thiab daim tawv nqaij ntawm lub casting yuav tsum tau muab ntxuav, tab sis ib tug tso cai.
7. Tsis muaj qhov tsis xws luag raug tso cai nyob rau hauv plaub xov pitches ntawm thawj tus ntsia hlau hauv lub qhov threaded.
8. Tsis muaj kev cuam tshuam rau kev siv cov castings, nrog kev pom zoo los ntawm tus neeg thov, tus neeg muag khoom tuaj yeem nqa tawm infiltration thiab kho (xws li kev kho vuam, kev kho deformation, thiab lwm yam) ntawm cov castings, thiab tuag castings tom qab kho yuav tsum raug. Kev soj ntsuam zoo sib xws.
9. Lub roughness ntawm lub puab nto ntawm lub casting yog 25um.
10. Tsis machined nto thiab machined nto ntawm castings
