Deckel Retrofit FP4A

I am keeping the old spindel configuration as i dont like the lost torque from and vfd
which is why i want to use the old gearbox
though i might replace the main spindle motor with an 5kw Servo when i got everything running for a while and got the money *cough* students poor

Good point. Forty year old electronics can be a nightmare.

Where did you buy the Lichuan servos?

Hi,

i have the same Machine FP4A with Heidenhain TNC355 Controller.

The difference between the Deckel and the Maho Gearbox is, that on the Deckel the Gear Motors are able to drive continously...

An important point is the valve Y10 on page 28 of your pdf. this is for the lubrication of the vertical head. normally you get no notice if this function works, at my machine the plc output was broken and sadly the vertical spindle bearings got no oil for an long time....

this should be the same gearbox forum.linuxcnc.org/12-milling/35316-retrofitting-a-deckel-fp5nc

I bought them directly from lichuan i messaged the email i got from aliexpress. So through that i managed to get then quite cheap
2 x 1.3Kw and once 2.6kw with a break with drivers for 980€ Plus shipping and Customs

Though now that i got then
the reason i bought them is because they support the +-10V from the Mesa 7i77
But i noticed that they also support Fancy Modbus over ethernet cable might actually be easier to controll then through that cause you can just connect them together but i dont know how that works

Yes it is thank you. But i cant seem to find him habing found a proper solution to his gearbox

do you have more papers in the orange book as scanned into the pdf?
there should be an outprint/drawing of the pc programm. Then may be i can help you.
unfortunately in the orange book from the later dialog11 and tncs this is not included anymore.
When i'm finished with my gildemeister adventure, the deckel is the next on the list for linuxcnc. so it makes no matter for me if i code this now or next year...
