Matanho Okushanda EMachining Gomba Rakanaka NeCarbide Round Bar

 When machining some high precision holes on mechanical parts, the reaming can be replaced by the carbide round bar drilling. When processing non-standard precision holes, it is easy to operate and can adapt to the processing of different metal materials. Iyo reming yealloy round bar drill imhando yekupedzisa gomba kushanda, iyo yakavakirwa pamakomba aripo uye yozogadziriswa nekudzokororwa kweakagadziridzwa uye pasi bhiti.

   Use a bit that is relatively new or whose dimensional accuracy of each part is close to the tolerance requirements. Because the drill bit will wear after being used for many times, it will affect the hole diameter accuracy. Micheto miviri yekucheka yebhiti ichagayiwa symmetrically sezvinobvira, uye axial runout yemicheto miviri ichadzorwa mukati me 0.05mm, kuitira kuti mutoro wemapendero maviri uenzane, kuitira kuti uwedzere kugadzikana kwekucheka. The radial runout of the bit shall be less than 0.003mm. Pre drilling can not produce more cold hard layer, otherwise it will increase drilling load and wear fine hole cemented carbide round bar.
