Much better idea how to cut irons (exclude pallasites) is EDM - Electrical Discharge Machining http://www.wireedm.com/wireedm.htm http://www.mech.kuleuven.be/pp/research/edm This can cut everything what conduct voltage, so graphite, iron or diamonds :) I remember photo of Canyon Diablo badly cut around nano diamond rich nodule, becouse it was impossible to cut using conventional methods. For EDM it could be easy. Also in diamond wire saw You can't use very thin wires for irons becouse it will simply tear off very fast. Maybe Mr Morgan can tell what thickness he usualy use for most irons vs stones? In EDM equipment I use wolfram wire have 0.12mm thickness. In diamond wire saw u can't even think about this thickness. Diamond wire cutting is perrfect for stony meteorites or pallasites. But for irons I want suggest EDM as a preffered method. Ofcourse there is alvays one "but"... What material You want to cut (how expensive and how big). Becouse cutting 5kg Campo will be also expensive and take many hours of cutting, and every hour cost. Anyway I dont see a sense of cutting campo not matter why :D In EDM You can very precise cut thick slice of historic iron into two thinner slices or cut small (lets say up to 500g) irons all types. There is also problem how to find good place to cut becouse this equipment is much more expensive than diamond wire saw, so not everyone will like to waste *expensive* time of his machine to cut strange piece of crap that some freak bring to him..... Anyway from my personal experience, if I can choose cutting iron for free on my diamond saw (not wire) or pay for EDM I choose ofcourse second option. I have less cut loses not only from cutting , but also from grinding becouse slices are much more flat than from typical diamond blade. Ofcourse diamond wire saw will make same flat surface as EDM but for me is much more expensive, something like 5x :) so calculations are simple. -----[ MARCIN CIMALA ]-----[ I.M.C.A.#3667 ]----- http://www.Meteoryty.pl marcin(at)meteoryty.pl http://www.PolandMET.com marcin(at)polandmet.com http://www.Gao-Guenie.com GSM: +48 (793) 567667 --------[ Member of Polish Meteoritical Society ]-------- Received on Thu 10 Mar 2011 09:11:41 PM PST |
