Sturdy Rotary Axis for CNC table

[Boyan Silyavski]

Thanks Dean. That clears some doubts.

Here is the lathe, it seems obvious enough what to do. Have to disassemble all and take measures of the shafts and pulleys that will need.





I assume the correct motor will be 400w, will have to make some calcs and if 1 or 2 pulley. The original motor is 250w.
I assume the final ratio should be something like 1:6 to 1:9 . I am a bit lost here as this is my first lathe and still haven't had the time to go deeper in lathe jobs. and what speeds i need for what.


I assume the holding torque of the servo works just like the power, so if geared enough the force will multiply.

Have seen very cheap taper roller bearings on eBay + the housing is aluminum, so heat will not be e problem even if rarely i need to spin it faster.
