摘要:
The cutting edge (3) comprises an oblique main cut (4) with an angle α1, a first facet (5) and a second facet (6) that are obliquely guided with an angle α2, the first facet (5) and the second facet (6) being simultaneously in cross-section of the rod (1) guided with rotational angles ε1 on one side and ε2 on the opposite side. Between the main cut (4) and the facets (5, 6) there is a rounded transition zone without a transition edge (7). At inclination α2, the first facet (5) is ground, while in the transition zone between the first facet (5) and the main ground (4), the angle changes from α2 to α1 continuously while the abrasive contact is uninterrupted and the rod (1) rotates around its longitudinal axis from angle ε1 to angle 0 to the plane of the main ground (4). The lancet (2) has removed the transition edge (7) between the veneers (5, 6) and the main cut, which improves the stabbing force. The lancet (2) is subsequently used mainly in the manufacture of lancets for human or veterinary use.Ostrie (3) zahŕňa šikmo vedený hlavný výbrus (4) s uhlom α1, prvú fazetu (5) a druhú fazetu (6), ktoré sú šikmo vedené s uhlom α2, pričom prvá fazeta (5) a druhá fazeta (6) sú zároveň v priečnom priereze tyčky (1) vedené s rotačnými uhlami ε1 na jednu stranu a ε2 na protiľahlú stranu. Medzi hlavným výbrusom (4) a fazetami (5, 6) je zaoblená prechodová zóna bez prechodovej hrany (7). Pri sklone α2 sa brúsi prvá fazeta (5), pričom v prechodovej zóne medzi prvou fazetou (5) a hlavným výbrusom (4) sa plynulo pri neprerušenom brúsnom dotyku mení uhol z α2 na α1 a zároveň sa tyčka (1) otáča okolo svojej pozdĺžnej osi z uhla ε1 na uhol 0 do roviny hlavného výbrusu (4). Lanceta (2) má odstránenú prechodovú hranu (7) medzi fazetami (5, 6) a hlavným výbrusom, čo zlepšuje priebeh vpichovej sily. Lanceta (2) je následne využitá najmä pri výrobe lanciet na humánne alebo veterinárne použitie.
