Hi guys,
I just purchased an old (1991 vintage) Techno 4x4 foot router. It came with a MAC100A controller which, although it seems to work fine, I will probably replace with something more modern. (If anyone needs a MAC100 with two spare driver cards and the Fanuc software, let me know.)
Anyhow, the real reason for my posting here is that I need to find a source for machine parts. For starters I will need at least one ball-nut. The Y-axis one is worn and missing one row of balls. I measured the screw, it is 15mm OD and the threads are spaced at 4mm. I measured the balls at 0.0984 inch and they appear to be all the same.
Are these fairly standard sizes? If so, what is a good source for a replacement ball-nut? The nut has a 2-bolt mounting pattern on one edge but if there is another mounting style more readily available I can probably make it work since I have a small milling machine.
Apparently Techno does not support their older machines, so it looks like I'm on my own. One of their salesmen was kind enough to send me a maintenance manual, but it is pretty generic and covers the whole range of machines.
Thanks,
Jim McMillan
