Retrofit options, 1991 Fanuc 0-M.

Post by eMTea »

Hi!

I have a 1991 Dah Lih MCV-610 (16 tools ATC turret), with Fanuc 0-M controller.

I would like to modernize it a bit, and found Centroid very interesting.

But to be honest, the Fanuc retrofit package solution is just too expensive, 3x the price of the mill.

Anyone done something similar, with a lower cost option?

First are you capable of doing such a conversion? Do you have a good handle on electrical/electronics? OR are you going to contract the work out?
Second, pictures of the machine, the current servo motors and their labels, servo drives, Spindle drive, overall good resolution of the control cabinet would be required.

The motion controller is a very small part of the expense of the conversion.

Technical and wiring I see myself capable of handeling, electrician by profession, and geniune technical interest takes me a long way.

I'll provide some detailed photos of the machine when I get home.
My conserns are the ATC bit, programming of plc functions to control it. Is the centroid plc software ok to get a hold on. I'm not very comfortable with ladders, FBD's are more logic to me.

You can always hire Marc Leonard (cncsnw) or Centroid to help you with the PLC portion. BUT you need to be very detailed on how the tool changer works and what sensors you have for the ATC, drawbar etc. If you decide to move forward, you might list all that information here first.

I think I have the original ladder diagram in one of the documents that came with the mill.

Centroid PLC programming is not the same as a PLC Ladder diagram. Though if you know how to read your machine's ladder diagram, it may help you document the process.

If you have documentation, you can find all the sensors involved, how they are wired etc.
If the machine is running being able to do a video of it changing tools, also finding all the sensors will go a long way.

DO post those video clips and pictures here on your build thread. DO create a Google Photo album and take lots of pictures as you go. Keep a large notepad near the machine for notes.
