    I wound up using an old laptop and a USB to RS-232 cable. Works well. I've only got four CNCs and they're in close proximity to each other, so I don't have a lot of ground to cover.

    There are straddle type tools that can utilize the Y axis and straddle the part as you cut. I think Sandvik makes one.

    My take is to learn G code. Relying on a CAM system can cripple you. if it's doing something you don't like, it would be difficult for you to fix it. Plus, even for simple shapes you would be...

    In my first shop, I made the mistake of using PVC from Home Depot. After a few startling explosions including one where a shut off valve ruffled my hair as it whistled past, I learned my lesson. ...

    Nothing wrong with a conventional (manual) machine, but I'm partial to CNC. My reasoning is that if you get busy and more than a handful of parts, the conventional machine tool is going to take up a...

    You may want to try jogging in reverse. Also, check the cabinet for anything popped or loose.

    As far as machining goes, hi-pressure coolant is quite beneficial. Depending on your coolant and other factors, you could wind up with a foaming issue.

    For me, not that much. Even the few times it did happen it usually falls clear and slams the chip conveyor belt. Like I said, we never really had a problem. The lube is constantly metered, the wipers...

    The big media and big corps are playing us off one another. Keep us fighting with each other over trivial shit while they sell the Country out. They fear the people.

    I've known Darryl for years, and worked with him when I was with Doosan. A real top quality guy and first class gentleman too.

    Doosan has exposed rails for X axis on many roller guide lathes. I never heard of a problem in the time I worked for them. They still have way wipers and lube so I don't think the machine would...

    There are a few advantages.

    You can boogey thru the part faster. You get a cleaner part off. The tool will last longer as it's more rigid.
    Downside, you have to tinker a little with the setup.

    Hi!

    I used to be Training/Applications for Doosan. I ran a few demos with Y axis parting as part of the demonstration. It worked REALLY well. It looked awkward, but the performance was terrific....

    Where were you 30 years ago? :D Dear old dad and my rotten Uncle made sure the family business got flushed down the toilet. Thankfully, I was smarter than they were, and was ready for them.

    I'm not sure where Doosan's pricing is anymore. Call your distributor. Doesn't hurt to ask. I do know they run specials.

    If you're cutting slots on the diameters, you'll *really* want a Y axis machine, or you won't be able to do much except rip a slot and hope for the best. The Y allows you to run the cutter around the...

    I know that Hopatcong Rigging will scrap it out. Call Gary and ask. Or you could put on Ebay or Craigs for $1000 with a vid of it running and someone will grab it either to use or for parts.
