Hi
We are restoring an old HFS12 surface grinder that we have now got a couple of problems with the Finimatic control, valves relays, anodes and cathodes.
The cross feed is working correct but the down feed will not pulse at the end of cross feed, adjusting the in feed control doesn't appear to be working, other than at the end of the cross feed it either doesn't count or will do 10 counts.
The down feed solenoid is powered all the time, for some reason?

We have fitted new three new valves and this fixed the cross feed problems.

We have also been in contact with Blohm to see if they still have some information such as an electrical schematic.

Hope someone out there can help
Best Regards

Hi
No luck so far in trying to fix the old electronics, unable to locate electrical schematics, so looks like we will have to set it up and run it manually until we can work out what to do.
I have a job I could do right now, but will have to farm it out I guess.

Regards
Burgs
