Usoro nke ịtụgharị ụkpụrụ n'elu nke workpiece na ngwá ọrụ knurling na lathe na-akpọ knurling.Ụkpụrụ a knurled na-enwekarị ụdị abụọ nke ọka kwụ ọtọ na ọka net, ma enwere nnukwu ma dị gịrịgịrị.A na-ekpebi oke nke ụkpụrụ ahụ site na nha nke pitch.
1.Ụdị knurling na ọdịdị nke ụkpụrụ knurling
A ga-ahọrọ ọkpụrụkpụ nke ụkpụrụ knurled dị ka dayameta nke knurled elu nke workpiece, nke ka dayameta ahụ buru ibu, nnukwu ụkpụrụ modulus;nke nta nke dayameta, obere modul ụkpụrụ.
2.Ọmụmaatụ nke akara achọrọ maka knurling
①Modulus m=0.2, ntụ ọka kwụ ọtọ, akara iwu ya bụ: ọka kwụ ọtọ m=0.2 (GB6403.3-1986).
② Reticulate m=0.3, knurling a na-emegharị anya, akara iwu ya bụ: reticulated m=0.3 (GB6403.3-1986).
3.Nhazi Knurling
(1) Wụnye workpiece.Nrụnye ga-abụrịrị ike dị ka o kwere mee.
① Mgbe ị na-etinye ihe eji arụ ọrụ, ogologo nke chack na-apụta kwesịrị ịbụ nke kacha mkpụmkpụ.
②A na-akwado ihe arụ ọrụ ogologo site n'elu.
③ Mgbe ị na-atụgharị mpụta okirikiri akụkụ knurled, dayameta ya kwesịrị ịbụ ihe dịka 0.25mm pere mpe karịa nha ikpeazụ.
(2) Wụnye mma knurling.
① Leba anya na a na-ehichasị ibe ndị dị na mma knurling.Ọ bụrụ na ọ dị mkpa, jiri ahịhịa waya hichaa ya.
② Mgbe ị na-etinye onye na-egbutu ọkpọ, a ga-ahazi ntụtụ pivot ka ọ were obere akụkụ tụgharịa ya.
④ Kpoo ngwá ọrụ ahụ nke ọma.
(3) Arụ ọrụ na-arụ ọrụ.
① Họrọ obere igbutu ọsọ na nnukwu nri.
②Bido mkpịsị ugodi nke igwe ma tinye coolant zuru oke na ngwa knurling.
③Kụgharịa mma knurling ka ọ bee n'ime ihe arụrụ arụ ma tinye nrụgide ruo mgbe etolitela ụkpụrụ diamond.
④ Na-azụ mma ahụ kwụ ọtọ wee nye ya nri ogologo oge ruo mgbe a ga-enweta ogologo knurled achọrọ.
⑤ Ife mma knurled ka ọ hapụ ngwa ọrụ ahụ ngwa ngwa.
(4) Ịgba ọsọ.
Na njedebe ihu nke workpiece, a na-ewepụ burrs site na ịcha chamfer 45 Celsius nke ruru ala nke oghere knurling.Obi dị elu.
③ Dezie mma nku anya n'anya, ma tụgharịa ya n'obere akụkụ maka mmeghe dị mfe.
④ Kpoo ngwá ọrụ ahụ nke ọma.
