Does anyone have an Adtech 9640 and has done what Adtech call elastic tapping?
A friend of mine recently purchased the aforementioned control and after a fair bit of work he has got it mostly working but the tapping is proving impossible.
He doesn't seem to be getting anywhere with the support from his supplier and also from China, the latest advice from them seems to be most people use step/dir servo spindles now and you have an analogue servo so you should change it.
To me that is not the solution, the manual states it can do rigid tapping which requires a step/dir servo BUT it also says it can do "elastic" tapping which basically translates to tapping with the Z axis closely following the spindles encoder.
I have recently fitted an SZGH CNC1000TDC control to my lathe and I have had no issues at all with the tapping (in simulation) and I am using an 11Kw induction motor controlled via a VFD so if the SZGH can do it with a VFD controlled motor surely the Adtech should be able to do it with an analogue controlled servo motor.
Hoping that someone out there can help as if not it looks like his control is basically useless for what he wants to do.
