I have a 1996 VMC4020HT we just bought. We were told it had rigid tapping. It came with the Fadal equipment record dated 1/96, the correct serial # & rigid tapping marked in accessory list. I could not find horsepower label in back panel. When we try rigid tapping cycle using G74.1, G74.2, G84.1 & G84.2 it taps like G84. Is there any way to find out if it has rigid tapping or am I programing this cycle wrong?

Thanks Speedy

I'm not sure how you are writing your program but, it should look something like this as a basic rigid program. Usually, you use a g84.. to set up rigid tap then you use a g84.1 to began the rigid tap. Some of the newest software does not require the g84.2.

G84.2

G84.1 R0+0 Z-1. Q0.0714 F750.
