bon, je prend ce post au vol pour poser des questions sur le perçage de trous..
bin oui, moi aussi je m'interesse à la question et mon domaine de competence ne se limite pas a la blagounette et au flooding (quoi que..
)
Voila, pour percer de la talonite, il faut:
"Drilling, Milling, and Reaming Talonite
Machining Talonite is accomplished using Carbide tooling. High Speed, Cobalt, and coated High Speed and Cobalt bits will not drill Talonite. For drilling, in my shop I use spade type bits, and carbide tipped spiral drill bits. Talonite drills very nicely, and a drilled hole looks like a reamed one. A reamed hole is stunningly smooth in Talonite. Where hole placement is critical, start the hole with a carbide spotting drill. I have also had good luck using carbide tipped masonry bits to drill weight reduction holes. I don't recommend using these bits for holes where the dimension is critical, every one I have used drills an oversize hole! Carbide end mills and reamers are also used working Talonite. In my limited experience, use the same speeds and feed as you would for hardened stainless steel. Talonite cannot be tapped by ordinary means. Carbide taps are very expensive and break easily. Threads can be formed in Talonite by EDM machining. An easy way to put threads in Talonite is to press a stainless steel or other material bushing into the place where the threads are needed and drill and tap."
je crois comprendre plus ou moins qu'il faut utiliser des forets "carbide", est-ce que c'est des forets carbures en french?
en naviguant sur le net, je trouve une boite qui fait çà
http://www.sgstool.com/products/skicarb.asp
des forets pour percer dans l'alu et les materiaux non-ferreux, non metalique...
Est-ce que la talonite est considérée comme non-metalique a votre avis?
vous qui avez des connaissances techniques bien plus élevées que les miennes, des explications du texte anglais sont les bien venues?
merchi !
