Don?t forget you can cut keyways or splines with the RELS.
Basically lock the spindle, I use an spring loaded plunger into a chuck that I previously jig bored holes at 15 degrees.around the circumference.
or you can use the angular RELS display.but still find a way to accurately lock the spindle.
I have some gears to cut in a 5 mm keyway.
Set up the tool 5 mm square HSS , set the correct C/L height,?
Set start and finish Z axis.with the stop buttons,
set initial depth of cut X axis,
Move the joystick to the left, push the rapid button, cut, it stops at the electric setting, move the joystick to the right and retract.
Move out the X axis a bit at a time to full depth,and keep repeating, normally in this case 2.6 mm deep.
I am sure there is a way to add on an additional firmware menu to do this, very similar to auto cut a thread, but the spindle is stationary.
I have to cut some keyways in gears later this week.
i will keep the forum posted.with photos.
Those with an interest in a simple indexer system for the lathe without timing gears or attachments to the end of the spindle. Gr!!!!!!!!! let me know.
You will need a mill, rotary table that tilts or that can accommodate 90 degree angle and boring head.
it?s a 2 hour job.
I must mention I have no keyway broaches and a press to push the tools through. IMHO with the RELS and some nifty boring bars to hold the
square HSS, I am OK.
I will also discuss how to make a boring bar to hold a square bit, if interested.It?s as simple fast design, 1/2 hour job.
No filing LOL involved.

Thanks

Just so happens that I bought a 6" Vertex H/V (horizontal/vertical) rotary table a couple of months ago, and I have a Chinese boring head that came with the micro-mill. I'm knee deep in building the MPCNC at the moment but things are cooling down in the garage so I'm looking for a good project to justify my new acquisition!

Yes, having had access to broaches during my working career, I'm not looking forward to cutting keyways on the lathe. Anything you can share to make my life easier will be greatly appreciated!

That is one of the reasons metal shapers are still popular among metalworking hobbyists. Keyways and splines are pretty easy to cut, including internal splines.

Interesting…I never knew vertical shapers existed!
