RE: [CAD_CAM_EDM_DRO] Servo torque requirements

Hello Jim

The motor/ballscrew combination might be great for one desktop
cnc app but not for others.

You can accurately analyze motor and drive requirements considering
what you want to do with a system wide software design package designed
for that purpose.

Such software can be found at:

It's free.

You may have to play some games with line wrap to get the link to load.

Subject: [CAD_CAM_EDM_DRO] Servo torque requirements




Greetings all,

Let me start with the disclaimer that I am a complete newbie to the CNC
arena, so if my
questions are nonsensical, bear with me.

I am planning a Benchtop CNC Mill using THK linear guides and some Parker
SM232 servos
I picked up for a great deal. I am shopping around for ballscrews and I
guess I'm not really
sure what I'm after.

The Parkers are rated for 161 oz-in continuous stall torque. I have seen
several larger lead
ballscrews, along the lines of 16mm/turn or so. I plan on using direct
coupling for the
servos, so reduction hasn't really been considered at this point. Would this
ballscrew be a
bit much for standard milling work with these servos?

I know discussing resolution is pointless, since the servos with 1000 line
encoders would
be far more precise than the rest of the machine could be. I don't think the
lead would be
limiting, but then I am a newb.

Thanks for any advice,

Jim
