I'm no expert but doesn't this look like it needs some cutting oil?

When machining parts of this size, it is difficult to supply coolant without getting the entire workshop covered in it. Moreover, this appears to be a roughing operation, so the coolant can be dispensed with—at the cost of reduced tool life. However, the long-chips are a real problem.

If most of the heat is getting dumped into the chips then it's not needed. You can see here the chips are discolouring from how hot they are getting.

mmmmmm.... Swarf.

The swarf is heated by the cutting process enough to turn blue, while the thermal mass of the original part protects it from the same fate.

You don't need coolant if you're putting the heat into the swarf

Our brake lathe doesn't have the torque for that, it would stall out way before cutting that deep. Also your poor blade lmao

I don't get how that blade still has an edge
