Hello,

Currently working with a Maho GR350C lathe, with the 432T control.
After solving some issues with the control everything seems to be working well.
Machine has live tools and a C-axis with an encoder on the spindle shaft.

Anyway, does anyone know what the best method to tap is with this machine?
I'd like to use rigid tapping if the machine can do it.
On my maho mill I use the G84 cycle, but this doesn't exist on the lathe.

Maybe you just use the G33 function like this? I normally use this function for outside threading

%PM
N9001
N1 G52
N2 G0 X200 Z200
N3 T1010 (M6x1 Tap)
N4 G0 Z2
N5 G0 X0 M8
N6 G97 S100 M3
N7 G33 Z-15 F1 M5
N8 G33 Z2 F1 M4
N9 G0 X200 Z200 M9
N10 M30

Or you use a G95?, so from N6 on program will be:

N6 G97 S100 M3
N7 G95 F1
N8 G1 Z-15 M5
N9 G1 Z2 M4
N10 G0 X200 Z200 M9
N11 M30

I'm not sure, but I think this will break the tap upon rotating from forward to reverse, maybe it will work with a tension/compression tap holder?
Another option might be to use the C-axis like this?

N4 G0 Z2
N5 G0 X0 M8
N6 G37 (This code activates the C axis)
N7 F36000 (This is in degrees / minute so 100rpm)
N8 G0 C0
N9 G1 Z-15 C6120 (Total Z travel is 17, times 360 degrees is 6120)
N10 G1 Z2 C0
N11 G0 X200 Z200
N12 M30


I guess I can try these examples with a tap in an ER collet and some delrin, but maybe there are some more 432T users on here?
