  • For production runs of one's own product, what would you say is the minimum cycle time for OPs that would make it worthwhile to get a Brother R650?

    I have a turret clamp switch alarm, check keep relay in a Puma 300 LM with FANUC 21i-tb control.

    I will answer it here but you should probably start a thread as the topic is far more involved. The shortest answer is if you are doing any production you want a rotating table. It doubles your table real estate and has around 2 seconds of spindle downtime when swapping parts. How much spindle downtime do you currently have when swapping parts?

    I saw a post you mentioned a pneumatic driver tool and I'm curious if that was an eBay find or if you have a brand recommendation for buying new? I'd need several of them for an assembly cell so scavenging for some mix-n-match used units might be more trouble than its worth...
    Do they have adjustable torque?
    Any guess on how accurate/repeatable they are?

    I like Uryu the best of the few I have used. They are made in Japan and have a real nice "feel" to them. They are sold by Aimco here in the U.S. who have a great website with lots of information, parts, and documentation on how to service them. I have only purchased mine on Ebay for up to $50 each, down to $20, but you can buy them new for around $700-$900.

    They really have to be abused to have any reliability issues so used is fairly safe. I find them to be very repeatable. I usually use them to drive the screws on uniforce type clamps and even clamping soft plastic I have never had an issue with repeatability. I honestly can't say enough good about them for what they do, you really have to try them out.

    Search Uryu LT on Ebay to see what they have. I like the ones with just the thumb piston to reverse vs the handle you have to depress to drive. I like 800-1100 rpm to drive screws better than the faster ones.
