Rau peb feem ntau HSS laum khoom khoom, muaj qhov sib txawv ua ntej, xws li yob forge, ntug hauv av thiab milled.
Cia peb qhia hom no raws li hauv qab no:
1.Roll Forged: the high speed steel is stretched and twisted according to a certain extent in the heating and softening and then roll forged the flute.
Piv txwv li: 70mm tag nrho ntev tuaj yeem ncav cuag 100mm. Yog li cov txheej txheem yob forged tuaj yeem txuag cov ntaub ntawv thiab muaj tus nqi qis. Thiab cov khoom
Are very cheap.
2. Edge Ground: it is to fine finish the goods on the basis of roll forged and make the shank diameter more precious. So the goods are more easy to drill holes
Thiab qhov kev pom zoo kuj zoo dua li yav dhau los.
3.Milled: the high speed steel is milled the flute by the milling cutter. Because the material is not stretched or twisted, so the run-out of goods made by milled is more precise than the goods made by roll forged. At the same time, the milled process takes the semi-automatic machine, so it needs people to control the machine,
Thiab qhov no nce tus nqi. Yog li feem ntau, cov txheej txheem milled nyob rau hauv siv rau qhov loj me me ntawm laum khoom.
4.Fully av yog lwm cov txheej txheem los tsim cov laum khoom. Raws li peb paub, feem ntau, cov txheej txheem milled siv rau
the large size(>13 hli)ntawm laum khoom. Yog li rau qhov loj me (tsawg dua lossis sib npaug li 13 hli) cov khoom siv tho, peb siv cov txheej txheem hauv av tag nrho.
The fully ground process takes the automatic machine. And the high speed steel is grinding the flute by the emery cutter.
Yog li nws zoo heev thiab muaj qhov ruaj khov zoo heev.
