Title: X3 4th Axis Thread Cutting
Post by: ausplex on November 25, 2009, 01:57:19 AM

Hi, just purchased an X3, and about to take delivery of a CNC Fusion CNC kit, steppers, controllers, etc... Have also purchased a Vertes HV-6 Rotary Table and will buy a Division Master conversion kit to create a 4th axis.

I'm interested if anyone has attempted thread cutting using a similar setup with Mach 3 control. The approach being to hold and slowly rotate the stock in the 4th axis, and have a milling cutter in the collet that has a 60 degree taper for cutting the thread.

ideas/thoughts/comments appreciated.

Have never done this or seen anybody doing this, but it sounds very doable to me as long as you have the right tool.

Simpson has a 4th axis that he is using to cut threads. Do a search.

Hi Rich,

Simpson uses his 4th axis like a lathe spindle and cuts the thread using a single point tool. The guy above wants to actually mill the thread using a milling cutter.

Understand Daniel, have never done any thread milling and internal and external can be done.
I'll leave the how to....to someone that does it or tried it.  ;)

Thanks for the replies.  Although this seems very feasible, I simply can't find any reference to it being done this way before. I have managed to find a couple of suppliers of 60 degree chamfer milling bits.

Interested to hear more from the community.
