Mattsson & Zetterlund VF600 Restoration

Gibs for saddle can be seen at these pictures, so it will partially explain why I said that this machine will need way scraping one day.IMG_0204.JPGIMG_0205.JPGIMG_0206.JPGIMG_0207.JPG
 
Well, servicing a Head and spindle was quite challenging. First, do be able to disassemble spindle, quill must be removed from housing. It goes up, but only after quill handle with returning spring was removed. Here is some pictures from the state "before" :).

Head is moving up/down with with the help of Rack & Pinion mechanism. Tilting a Head is accomplished with Worm Gear mechanism. This machine was used (and abused) as it can be seen on worm gear (on first picture). Luckily, I was able to rotate Worm gear for 180 degree, so part of worm gear where teeth was broken are not engaged any more. On third and fourth picture mechanism for moving head up/down and tilting Head can be seen, mounted on the machine.

That is a very interesting machine. Seems to be comparable in size to a round column mill drill but with better rigidity. Too bad they are rare, I will probably never see one in person.
 
Now, starts the fun :dejected: Outer race has to be removed from Housing. But, there is no place between race and Housing for claw to catch race and pull it. There is interesting video how this kind of problem can be solved. It was help me very much.


...and this is how I was do that :) On first picture, inner thread of the Housing is protected or "protected" with thin metal plate stuck on the position with masking tape. Piece of bar stick welded to inner race on the second picture. Finaly, inner race removed from Housing on third picture.

Stick welding is not the best welding method for this operation, but, it is the only welding method available to me at this moment, so I did it with what I have. Completely successful. :cool:
