Drile Sàbh Toll Dà-Mheatailt Gearradair Toll HSS airson Fiodh is Meatailt
Taisbeanadh Bathar
Air a dhealbhadh le claisean ugh-chruthach fada, tha am bior seo air a dhealbhadh gus sgoltagan fiodha a thoirt air falbh bho phròiseactan obair-fiodha gu furasta agus an uairsin an fhuarachadh sìos gu h-èifeachdach. Faodar fuaradair leithid uisge a chleachdadh gus casg a chuir air cus teasachadh rè obrachaidhean drileadh.
Le bhith a’ cleachdadh stuth dà-mheatailt àrd-inbhe, tha an toradh seo dìonach an aghaidh meirg, 2mm de thighead, nas seasmhaiche, agus tha beatha seirbheis 50% nas fhaide aige; tha e a’ nochdadh deagh sheasamh an aghaidh creimeadh agus teas cuideachd. Tha an togail dà-mheatailt a’ toirt seachad barrachd cruas, ga dhèanamh freagarrach dha luchd-cleachdaidh a tha a’ sireadh dòigh luath, ghlan airson meatailt a ghearradh. Tha aloidhean sinc air leth seasmhach, dìonach an aghaidh creimeadh, agus air leth duilich a ghearradh.
Le lann fhiaclach, bidh an gearradh nas luaithe agus nas socair. Tha seata de fhiaclan biorach ann a bheir gearraidhean glan, rèidh. Tha e cuideachd gu math mionaideach, agus tha e ag atharrachadh eadar 43mm agus 50mm a rèir meud an tuill a thathar a’ gearradh.
Tha rabhadh ann nach eilear a’ moladh an t-sàbh toll seo a chleachdadh air concrait, leacan ceirmeag, no meatailt tiugh. Chan eil mandrel agus drile pìleat ann.
