Lorch B30LZ

[Selfmade]

Last week I bought this lathe from a German dealer. It's a Lorch B30LZ hight precision lathe from 1975. It is in a very good condition and the dealer gave me a lot of tools surplus.

The next month, I beginn to recondition the lathe, so that it looks like new.

Best regards

Lathe looks real nice, but the carrige looks different... More elektric than machanical controls.What is the function of all those buttons?

BTW, do I see a Macmom in the background?

 

[Selfmade]

Yes, it's a Macmon 100, a Deckel FP1 clone.

The buttons on the carrige have the function as followed:

The three buttons on top control the electromagnitic clutch: 1. carrige feed left/right, 2. Stop feed, 3. Crossfeed forward/back

The three buttons on the side: 1. start spindel, 2. stop spindel, 3. reverse spindel

These buttons helps very much to work ergonomical and economical.

Now the work begins. The iron case becomes a new paint (RAL 6011 as original). I send the bed to a surface grinder because it is hardened and so it is impossible to scrap.

All the mechanical parts have to be cleaned and all the bearing will be replaced.

Is the bed mounted on the frame while grinding?(for the best results)

I got the bed back today. The grinding work was done by "de rooy" in NL.
The work they did is superb. They have modern grinding machines and work professional.

How Is It Going ?? ???

Hey G

Do you have an update on your project????

Nice looking lathe, I like the electrical controls..... Are these aftermarket or optional from the factory. Nice for series work and so on. Donn't forget a DRO !

Here a few pictures of the recondition process. The painting (2K-PUR paint) is ready and the saddle milled and finished with moglice.
Next steps: scrapping the apron and bedways of the cross-slide

Nice !

Nice progress, Thanks for the post.
Would you mind going into alittle more depth of what you are machining in the pics????
Machining before grinding?????
I have never restored a lathe before... sorry for asking idiot questions....
If I don't ask I will never know.

It`s finished,

after several weeks of hard work, the Lorch is in a perfect shape. As new. The tolerances are better as new. here a few pictures of the lathe.

Threading on your lathe?

It appears that there are no threads on the lead screw, so how do you cut threads?

The lead screw is under the bed, protected from dirt and splinters. You can`t see it on the pictures. What you see is the bar for the sliding and surfacing feeds.

Good work, lathe is indeed looking like new.

Beautiful work on the lathe! I have never seen one of these lathes in person, but it seems like there was a lot of thought put into the controls. What did you end up doing with the tooling that was under the lathe?

The tooling was reconditioned too. I´ll build a new case for the tooling in the next weeks.
