Advice on buying servos.

[lp_felix]

Hi guys, I'm going to build a machine to drill and tapping one part, I'm thinking use a servo for tapping and a regular spindle for drilling. Using a regular servo I can do rigid M3 tapping on 2mm aluminium sheet? Have anyone experience with something similar? Tks

To do rigid tapping you will need a quadrature encoder on the servo and some thing like Linuxcnc to control it.

Here is a link in Portugal where you can buy the Mesa cards 6i25 with 7i77 bob will do it.

Are you think of having the spindle and servo on the same gantry?

You can also do rigid tapping with UCCNC, and with Mach3/4 with the right motion controller.

Hi Ger21, in fact I planing use uccnc. I have a spare Uc300 5lpt (from other unfinished project) I will read the manual.
Thanks for the tip.

If it is always the same tap, no pitch change, why not gear vertical displacement to rotation? Drive it with anything you like.

Yes, spindle and servo on same gantry.. Ok, I have a lot of questions but i will study quadrature encoder and servo first, and do stupid questions later.. Thank you for the help.
