That is a lot of swarf to process!
I would think that they would be very diligent in their recycling to the point of gathering the dust particles that are generated from the machining - whilst the stainless swarf would be worth a tidy sum in recycling the titanium, gold and platinum would be worth a very tidy sum and you could not afford not to recycle it.
Michael - if you do cover the case making in further detail down the track I would be interested in hearing if there are separate production lines dependant on the metal being used or if a extremely careful cleaning process is done after each run of a given metal and if dry or wet machining is done. I would imagine that with the precious metals the value of the swarf would be much greater if there was no cross contamination to the point that the lathes, mills etc would need a complete and thorough clean down to gather up the dust particles generated from the machining process - not just the more tangible off cuts.
I would also think that wet machining (to lubricate and cool) would make the collection process a little tougher but still possible, with particle filters in the cooling system etc to gather as much as possible.
I would guess that the blanks / raw bar stock are produced by third parties? And if so, there would be a bi-lateral agreement to return swarf / wastage to those suppliers for re-processing?
Thanks for a great topic :)
