If you recall, I changed over my lathe chuck and obtained a great
improvement in lathe accuracy and finish quality. In both cases, I
made a shallow cut at a the slowest automatic feed settings.

Today I discovered something else: that if I do the same thing -- make
a shallow cut at the lowest feed setting -- but using coolant, the
finish improved beyond my wildest expectations, in fact, the turned
rod looks as if it was polished, with no visible imperfections.

Also, quite likely related, the chip made when using coolant, would
not break all the time, and instead it produced super long spiral
continuous chips.

I saved all three samples just for reference purposes.


Igy just reinvented the wheel.

Congratulations.

Now you need to use a surface finish gauge and try various coolants and
admixtures.

This should keep you entertained for many months
