Hello all!
I have done several CNC conversions, so I am not new to the game.
I have a PM cylindrical grinder that I have often wanted to retrofit to cnc. I have ballscrews, stepper motors and all of the nessicary components.
This grinder is a simple 2 axis machine with wheelhead. I am wondering how cnc cylindrical grinders do tapers and contours with a straight dressed wheel? I know some of them have swivel wheelheads, and they must have a post processor that trigs out where to be per the required angle.
If I convert this machine, I wont have a swivel wheelhead. When a cnc grinder does not have one, does the controller (mach3 in my case) just apply whatever tool tip profile/offset I program in in my cad program (bobcad in my case)
I anticipate using bobcad lathe ver 24 or 25 (have both) and mach 3 lathe for control, just like I do with my CHNC hardinge lathe retrofit.
Anyone have any experience to share with this stuff?
Thanks,
Nate.
