Gildemeister NEF 480 Retrofit

Played a bit more with the x axis
And looks quite nice so far:



Found an error in the input scale and after fixing it it went full speed and was spot on

​

​

Now I need to tune it fully.

Got the automatic lube system running.
What is not running is the indes Signal from the encoder, so homing with index is not running yet. This is an issue I need to address and recheck the wiring.

My belt pulled are ready to be shipped. So There might be more progress in the next weeks.
I allow started to tool up, so I can make chips with this beast.
Still an open question is the the chuck. I wonder if I should change it.
On one hand the Chuck is nice for repetitive work, but I think a normal chuck should be more versatile. I was thinking about simply holding a normal 160mm chuck in this 250mm beast, but everyone tole me it’s not safe. I am nit sure If I can fit a 160mm chuck to my din 55022/27 size 6 spindle nose. The mach plates for 160mm chucks are only available in size 5. Is a 160mm chuck on as size 6 just uncommon or impossible to fit

after some trouble the tight pulleys arrived:

low I just need to make the locking devices to clamp the pulleys to the shaft. And make some light modifications to the housing to fit the new bigger pulley.
But this will get me from 0.0012 mm/p to 0.001 mm/p what are actually 0.00025mm/p with the servo drives. only issue at the moment it I don't get the index from the servos for homing but I can home without indes for now.
Looking forward to also get the Z-Axis moving

after some grinding the new pulley fits

this session then ended when I tried to machine the the bore for the clamping thingies. the pulley is to big for ma old lathe and I can't clamp on the recess cause I can't flip it 180° cause the it won't fit.
So the new plan is too machine it in the mill, but this is not a Sunday project.

The small pulley flanges look to have gone missing?
