Chip Blaster / High Pressure Coolant - Titanium Alloy
Has anyone used high pressure coolant (1000psi) when turning titanium alloy (Ti6al4V, etc)?
Salesmen from Kennametal, SECO and Sandvik tell me that you will see a either:
1) A major increase in tool life at the same SFM.
2) Similar tool life at double the standard SFM.
Kennametal uses the Beyond Blast system which is coolant through the insert. SECO has their Jetstream system which is a custom holder
where the coolant is blasted right at the chip shearing zone.
Comments from anyone who has used these systems or comparable would be appreciated. Pros / cons, good / bad, etc.
I havn't used it, but it would make sense, since Ti puts most of your heat in your tool, blowing coolant through it would help...
We just plumbed our 175psi shop air through our flood, and gained like 300 SFM on 6061 with just that, basically coolant through on lathe tools, seems like a win, depending on how busy you are and what the tools are worth...
There's a pretty good article about it in Production Machining, Cutting Tool Enginerering, or one of that family anyways, probably 4 months back...
