Wow! someone else who's doing Diamond Turning!!! Hi There
Are you machining Aluminium? if so I assume that the swarf comes of in a big long silvery thread?
The trouble I find with swarf extraction is that you can get it started, but it always clogs up eventualy.. even using the veturi system.
Incidentaly, I find that coolant positioining is important to force the swarf away from the tool.
When machining plastics I have a larg diameter extraction system from Air Cleaning Systems here in the UK, it needs cleaning abot once a week.
Oh, Diamond Machiners are notorious for taking their machines to bits and tinkering with them... be careful if you leave the enclosures off when machining Aluminium as the swarf conducts electricity and can short out boards etc.
Anyways! nice to meet you
