Thread: Knurling for those without coolant.

Hi BT,
A timely post. I just finished yesterday making a Lathe Tool Height gauge. I have been meaning to make one for years as I have a rear mounted parting tool and needed a universal height setting tool. I thought it would look nicer with a bit of knurling on the shank and give you something to grip,it is adjustable and has a rare earth magnet epoxied into the base. The shank is 30 mm diameter, I ran the lathe/Clamp type knurler at 100 RPM. As you know I use ATF oil in my lathe and mill. When knurling I have the supply running wide open, this flushes all of the chips away and keeps the heat down. ATF oil is a lot better at lubricating than Kero or Diesel and it does not smell like they do.
Regards Bob

Well .... me! We could be playing snap!



I use mine frequently, mainly to set my boring bars to the correct height ( I dont have enough tool holders ).

PS, That is some crisp looking knurling Bob.

Hi Bob.
I use cutting oil and air to clear the chips . seem to work well.

Peter,

I can remember a warning from years ago about compressed air blasting swarf and grit into places in machines where it shouldn't be so I've heeded that warning. What are you using as cutting oil?

Bob,

The gauge is 7 KM away but from a poor memory I reckon just under 50mm. It would probably have started off as 2" 1214.

Bob.

Thanks for this

atf and air are not so good a combination
the stuff is pretty harmfull if you speak danish, norwegian or swedish
not so if you speak german

Some time ago we had a plastic bottle of atf oem Volvo.
I had a look at the warnings on the lable.
The three nordic languages are all kind of similar and fairly understandable if you speak dutch.

In all three nordic languages there were comprehensive warnings not to breath in particles.
It even stated max ppm and possible effects/symptoms.
They all were a little different though.

In german it only stated to not dispose off into the aeqious system as it would harm fish.......

Hi Bob.
the cutting oil i use was from NIMT which were given to me by a friend who teaching there so i'm not sure which grade it is but it is used for tapping and drilling in school .
when i use the air i went very close to the job being knurl , it work very well for me .

Hello Jan,

I had a look at some ATF safety data sheets online and as per your observation, the level of danger associated with ATF depends on the country in which it is sold. Here are a couple of examples. First, the USA then Turkey.
