Re: [CAD_CAM_EDM_DRO] Motorising a rotary table

I'll try again, the last message I sent seems to have got lost.


To see how I did it on a 150mm table, see:

You can find the CNCzone thread at:

Using it in programme mode, see:

I have a 400mm rotary table that I wish to mechanise and understand that I need to fit a servo motor to it. I would propose to mount the motor to the input shaft after removing the handwheel .

Doing the mechanical is not a problem for me and even the wiring if I know what to do.  Please can anyone help me with information of what I need to buy and how to wire things up.  The handwheel to table ratio is 40:1 and I need to be able to control the table rotation from zero to 5 rpm.

I envisage controlling the motor either from a switch or a foot pedal.  It would be handy if the motor could cause the table to rotate once and then stop but this isn't vital.


Many thanks for any help that may be given.

Mike
