Ar gyfer ein cynhyrchion darnau dril HSS yn bennaf, mae yna wahanol ragflaeniadau, fel efail y gofrestr, tir ymyl a melino.
Gadewch inni gyflwyno'r mathau hyn fel a ganlyn:
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.
Er enghraifft: gellir ymestyn hyd cyffredinol 70mm i 100mm. Felly gall y broses ffurfio rholio arbed y deunyddiau a chael cost isel. A'r nwyddau
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
Ac mae'r rhagolygon hefyd yn edrych yn well nag o'r blaen.
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,
Ac mae hyn yn cynyddu'r gost. Felly yn gyffredinol, defnyddir y broses felin ar gyfer maint mawr y darnau drilio.
Mae 4.Fully ground yn broses arall i gynhyrchu'r darnau dril. Fel y gwyddom, yn gyffredinol, defnyddir y broses melino ar gyfer
the large size(>13mm)o ddarnau dril. Felly ar gyfer y darnau drilio maint arferol (Llai na neu'n hafal i 13mm), rydym yn cymryd y broses lawn.
The fully ground process takes the automatic machine. And the high speed steel is grinding the flute by the emery cutter.
Felly mae'n effeithiol iawn ac mae ganddo ansawdd sefydlog iawn.
