I am listening long to that Forum now its time to post ,..
I was asked to help decide and retrofit an Steel able precise Lathe and Mill
So to make it long short we want Europe Quality (who buys cheap buys expenseve in the end) and it should be able to also Mill Steel.
So we found (after visiting the Factory yes it is build in Europe and the quality section has made the buy decision) Klippfeld. And we decided to buy the machine and ask the factory to integrate the Steppers (which we delivered)
so here is the Story.
That is the machine delivered (Mill was not installed then )
We decided also to stay away from chinese stuff where possible and relevant. So we bought Tripple Beast CNC COntrol form Germany
(This was the Testbuild)
Here is an Closeup where you can see Power Supply , Fan, and Cabling
Here is an Picture without cover of the (Mill X) Lathe Z Axis where Simply the Handwheel is still avail and the stepper beside.
In Action there is an Steel cover.
Here is an Picture of the (Mill y) and Lathe X axis
And the Wires are secured inside with laces
Ant there is an Steel Cover wehre after a Wrong approach ( ) the endstopp is mounted.
Note the rubber cover which is really a good idea you can easily clean and still have protection.
Now on Mill Part there is an Mill Z axis here you see the stepper
And here you see the Mill Z Endstp mount
The next EndStopp is the Lathe Z (Mill X )
It is an 3d Printed Part (which Screw Head inside) but this solution is crap
Version 2 is better
You can see the steel bar where the Mecanical off is.
In that manner the machine stays cnc and manual operateable.
But version 3 Works perfect
So now it is time for a tour around the machine.
Clean Box all metal and an Electronic speed control (to be connected with CNC Control )
Here an better picture and the toolholders
A rigid steel part and clean design
Then the big and precice handwheel i wanted it to be still manual operateable
Here the backside of the support
And the manual control for the gear.
Here the Boring Support and you can see i made the Steppers pluggable.
Now the Milling Part
Here is the Mill Left Right On off and Speed Control
Also to be CNC Connected.
Here The engine and the big Z Spindle in the back.
Here the mill setup with an Plexi -Guard
And the machine is EMC2 Linuxcnc operated.
The lathe setup was straight vorward. I did reach on 10cm +- 0,05mm in Alu.
So quite ok.
The Milling Setup was tricky because the Z Axis is done by the "Pinole" (like and drillpress) which worked well in hardenable steel but to get it precicse was some tinkering necessary.
i hope i gave some people some inspirience and trust that ist makes sense and is possible.
My next steps are Lathe toolchanger
(this is my 3d printed model for test )
and an handwheel
(This is an almost working example for test )
