Single point knurl?

[Forced_Firebird]

We have a job we are doing with knurling and have the tool all setup and works great. A neighbor came over and was talking about using left and right hand threads to single point the knurl.

 

We tried it and didn't come out as expected, have any of you guys had experience with it, or even heard of it?

 

Thanks,

If you are talking about turning on a lathe, I have never tried to single point a knurl and don't think I would try it. You would have to calculate numerous starting points equally spaced on the circumference and then synchronize the "Z" starting place for each cut, the feed per revolution would be very high and I would guess there would be lots of burrs kicked up.

 

Investing in a GOOD knurling tool will give you lots of beautiful knurls with a lot less work and more consistency.

PhilCott is right. Just because it can be doesn't mean it should be done. Stay with a good knurl tool.

The job was running great, so we changed it..? I love when that happens

Did your neighbor tell you this on April 1st?

Thanks for confirming my suspicions guys. I thought he was talking out the side of his head.

 

Job ran fine, we just decided to try it on a spare part, and after several thread pitches, it still looked like a double thread to us.

 

I milled a knurling tool to hold a standard diamond knurling set using an old insert holder (also milled to fit) and home-made wedges...

 

 

 

and for small diameter, we modified a Swiss screw machine tool to fit in the Mori...

 

 

 

Thanks for getting my back on an argument we knew we were right on
