Lathe Coolant... 1

[NickE]

we are setting up a new (used) lathe, it's a FEMCO DURGA-25E

We will be using it for production machining of 4130 DOM tubing, using coated carbide tooling.

What coolant would you use and why?

some obvious things that we would prefer

Compatible with the workpiece, tooling, and machine.

Low Hazard, easy to dispose, long lasting

American Made, Operator Safe....

Thanks

Nick

Will this be mostly (all?) turning operations? What about drilling? Threading? Tapping of internal threads? Does it need to provide temporary corrosion resistance for subsequent transportation and storage? For general turning, there are lots of good options for soluble oil metalworking fluids:

If you're just turning and/or boring and using carbide you may not need coolant. Carbide works well when hot and tends to break if the coolant flow is inconsistent.

All turning, no planned drilling or boring.

One component:
ID Turn/Cut to length

Other component:
internal thread/face/cut to length

I have been doing coolant analysis and management for about 20 years and I can guarantee you that there has never been a coolant made that could not be screwed up through neglect and mismanagement.
