/diy/ - Do It Yourself

Can I use a stepper to directly compress an object without springs?

It's a metal shaft I'm going to be compressing a glued object to. I want to have the motor move the glued item along a rail until touches the shaft, then exert force continually for a minute.

Will this cause the motor to slip? Will this cause damage or loose pressure on the shaft?

I understand I can use springs, however this would be difficult as I would then need more linear guides for the spring action as to keep the glued item straight and evenly compressed along the shaft, which is narrow.

Right now keeping the rail tight with as little play is needed for the precision required, I understand pneumatic cylinders would be best for a constant even pressure, however that's just not possible.
