Hello

 

I have Ruhla type 59 universal milling machine which I believe is East-German Deckel FP3? copy.  It’s table is not quite parallel to the axis but I have not find a way to align it. Can somebody give me instructions or hint how can I align the table?

 

Thank You. (and I Regret my bad English)

Yours Jouni

Jouni,
The Ruhla is not a Deckel copy, more nearly a Thiel copy and it was Thiel from which Deckel were also inspired & developed. Have a look here:

Regarding the table, you have not said whether the alignment is out in a horizontal or vertical plane, or whether it is a fixed table or swivelling one. How much is the error? If the error is small, say a 004″ (0.1mm) over the length and the table is not an adjustable/tilting/swivelling type, you probably need to remove it and check for damage or swarf under or behind the mounting face.

 

The table is bolted to the front of the vertical face of the ‘carriage’ of the machine. There should be at least 4 bolts in tee slots to retain the table. If you remove the nuts the table can be lifted away. Be careful, the fixed table is probably 40kg. 

 

If it is a tilting &/or swivelling one, it will be a heavier, but you can obviously adjust it after loosening the adjustment locking bolts.

I thought that Thiel and Ruhla were Deckel copies, but I was wrong. That also explains why my Ruhla does not look exactly like Deckel…

 

My swivelling table alignment was out in horizontal plane. Something like 0.4 mm over the length of 400 mm. Today I broke table to the bits and made clean up. Now alignment is better, About 0.07 mm over 400 mm.

Not good but better.

 

Thank You. I just understood that I have just 2 bolts in tee slots. I have to make two more.
