Menetfúrás előfúrás táblázat
Az előfúró táblázat hasznos segédlet, amely megkönnyíti a megfelelő furatátmérő kiválasztását, amikor belső menet készítése a cél. Legyen szó gépi vagy kézi menetfúrásról, a megfelelő méretű előfúrás elengedhetetlen a pontos, jól illeszkedő menet kialakításához, és a szerszám élettartamának megőrzéséhez.
A lenti menetfúrás előfúró táblázat segítségével egyszerűen kiválaszthatod a megfelelő előfúró méretet az adott menethez – legyen szó:
- metrikus menetről,
- finommenetről (UNF),
- durvamenetről (UNC),
- vagy gázmenetről (G).
A menetfúráshoz természetesen nemcsak a megfelelő furat, hanem a hozzá illő szerszám is elengedhetetlen – ehhez ajánljuk minőségi menetfúróinkat, valamint a menetfúráshoz kifejlesztett menetvágó spray használatát, amely csökkenti a súrlódást és növeli a szerszám élettartamát
