CNC Broach Tool client films their automated Haas mill broaching of a blind internal keyway documenting 250 keyways per cutting edge in 1215 steel using keyway cutters from www.cncbroachtools.com

Basic M/G code with some macros is used to generate the program. To cut this keyway in a cnc it requires multiple passes with the broaching tool. Using macros will shorten the length of the program plus will give you some flexibility with trying different depths of cut.

Done this many times, but never went the macro method, just simply programmed an M97 P, with an L count that was my depth of cut, divided by my cut per pass. About 4 lines of code and you're off to the races. I do like the off-the-shelf tools for this though. I always have had to custom grind my own, or have a grind shop do it for me. As for the haas being able to do this, it is true they can, but it has to be one with a Vector Drive spindle. The older models, say pre-1997 or 98 had a pin that locked the spindle and it did not orientate it accurately and or held it in position good enough to do this. You will screw up your spindle on one of the older machines and ruin your broach.

That process is not broaching but sloting. A broach is a linear multi tooth profile cutter. The tool shown is a internal keyway cutter.

What kind of rake do you find works best for you? It looks like you're only running 1-2 degrees there which is impressive but I feel like it would lead to excessive rubbing?

Which software you're using for this broaching keyway? Or whats the name of the cam operation to make sure turns spindle stay locked ??

how in a Haas, they dont have a true spindle locktalked to haaz about it today

So the question is simple. Does the producer of the HAAS machine anticipate the use of a milling machine for making slots by chiselling in a continuous production process? Doesn't that risk voiding the warranty in the event of a failure caused by overloading the spindle in this way? Isn't it that the spindle load is calculated only for the rotary motion and not for the reciprocating motion?

@@MegaJohnhammond yes just use either a p value or a s value. So the code would look like M19 P250.456 the p and s are going to be the spindle angle of the broach.

@@scottbrooks6571 I'm not cnc machinist but I wonder how is it possible without physically locking the spindle somehow. The holding force comes just from spindle motor? Is it servo with a brake or what?
