Maidir lenár dtáirgí giotán druileála HSS den chuid is mó, tá tosaíochtaí éagsúla ann, mar shampla brionnú rolla, talamh imeall agus meilte.
Lig dúinn na cineálacha seo a thabhairt isteach mar seo a leanas:
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.
Mar shampla: is féidir an fad iomlán 70mm a shíneadh go 100mm. Mar sin is féidir leis an bpróiseas brionnaithe rolla na hábhair a shábháil agus costas íseal a bheith aige. Agus na hearraí
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
Agus tá cuma níos fearr ar an dearcadh freisin ná mar a bhí roimhe.
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,
Agus seo méadú ar an gcostas. Mar sin, go ginearálta, úsáidtear an próiseas meilte i méid mór na n-giotán druileála.
Is próiseas eile é 4.Fully ground chun na giotán druileála a mhonarú. Mar is eol dúinn, go ginearálta, is é an próiseas meilte a úsáidtear le haghaidh
the large size(>13mm)de ghiotán druileála. Mar sin, maidir leis an ngnáthmhéid (Níos lú ná nó cothrom le 13mm) giotán druileála, glacaimid an próiseas talamh iomlán.
The fully ground process takes the automatic machine. And the high speed steel is grinding the flute by the emery cutter.
Mar sin tá sé an-éifeachtach agus tá cáilíocht an-chobhsaí aige.
