BACKGROUND: We are a plastic injection molding company. We have a line of off-the-shelf enclosures that we cut various holes in for thousands of different customers. New Age Enclosures | Official Site The parts are typically 2-5" rectangle. Basically, we're cutting button holes into remote control cases. That's not exactly what we're doing every time, but that's the concept and the sizes we're dealing with just for reference. We have thousands of customers and they all want something different in a different box.
PROBLEM: We have to cut holes (2nd operation) in the boxes. We're doing this on two Haas TM1 milling machines. We make aluminum fixtures (core side) to hold one or two of the cases. So it's basically load the part, lock the clamp, press the GO button on the Haas, the mill comes down and cuts a rectangle or two, then retracts, then the operator removes the part, blows off the core, and repeats the cycle. I NEED TO SPEED THIS UP.
MY IDEA: Build two identical fixtures (for every part we make) and put them back to back on a rotating table. Then while the machine is cutting the part on the backside we're swapping the part on the frontside, then the table rotates 180 degrees so we can rinse and repeat. Theoretically the mill never stops.
WHAT I NEED FROM YOU: I need help identifying the right rotating table. It's got to be motor driven. It's got to be fairly accurate +/- .001". It needs to be big enough to hold two fixtures so I think 12" diameter would be good enough, but bigger would be better. THEN, what's the command to rotate the table 180? I can't say money is no object, but it's got to do what it needs to do and the cost is just what it costs.
Thank you for reading this far, and thank you for taking the time to help me out. I've researched but I've seen prices anywhere from $300 to $11k so it's obvious I don't know exactly what I'm looking for.
