Sanding and polishing acrylic plastic

Hi:

I am new to the forums, and am interested in finding out more
on sanding and polishing acrylic plastic into jewelry
components.

It is a new process for me and I was interested to find out if I have
a large batch of cut acrylic pieces is it possible to reduce my
sanding and polishing time if I use a rotary or vibrating tumbler?
Any other suggestions are also welcome.

Thanks
