Show"N"Tell ( Your Machines) / 1979 Shizoka retrofit project
« on: February 16, 2008, 02:12:49 AM »
Hello,
I am new to this forum. I am hoping to glean information and share in the future.
I have recently purchased a 3 axis CNC. A 1979 Shizoka STN, manual tool changer. This machine has a General Numeric 5 series controller, pre-Fanuc. Pretty old stuff!! The x axis has a problem, what I don't know. I would like to remove the controller and retrofit to a PC based control. I may have to replace the servos for compatibility reasons. I have been looking around at stepper motors and drives that would be PC compatible. I have many questions. So I will ask the most important right now.
Are stepper motors the right direction for replacing the old DC servos?
I have looked at some CNC retrofit packages but the prices are just to pricey for this machine. For 8K and over I could buy a good running machine without having to rebuild it.
Any input would be great.
Thanks,
Tom
