Finishing equipment for small aluminum parts

We need to make a decision about buying polishing/deburring equipment to polish/deburr/finish small pieces made of 6061-T6 Aluminum machined in automatic screw machines, we need very good finishing and most important, two clean and burr-free internal threads of M8X1 and 0.210"X36 TPI. What kind of equipment would be the most suitable and cost-effective for this application.

Thanks.

Sergio You failed to mention the maximum size of the parts you want to process, quantity/hr.or day and what surface finish you require on finished part. Is the hole through hole or blind? Does part get anodized? This is important for selecting the right equipment or size machine.
