    Alarm "A" is a very high level alarm. There's a major short, a cooked board or motor.

    The OSP is really tough to beat for processing. It's FAST. It has multiple CPU's and can really process the code. Yeah, it's expensive. You get what you pay for.

    Highly NOT recommended to change offsets mid-cut! Too easy to go "boom."
    I think Mtndew has the right idea.

    On newer Fanuc controls they won't allow the use of G41/G42 during a multiple roughing cycle anymore. I used to get this complaint when I worked at Doosan. You can put it in, but unless it's a G70...

    Yes. I give a reason. I rarely "no quote" things but when I do it's because the job may be outside my abilities, my machine capability, or there's no way to achieve the customer's goals.

    You can run standard CAT 40 tooling in a Doosan Big Plus spindle. Same for Doosan CAT 50. Won't hurt a thing and won't void warranty.

    The tool polarity - no. But, as stated above the orientation of the tool has great impact on TNR.

    I used to work for Doosan, and they made a great HMC. They were generally Fanuc which is what you don't want. Okuma makes a great machine and the OSP is a rock solid control. DMG Mori makes a top...

    Biggest error I see is that you go from M35 Mill mode to M34 turn mode.
    Also many of those M codes should be by themselves.

    I cut a lot of UHMW and other plastics. I had a few layers of cheesecloth on the conveyor and then scooped/vacuumed it out when done. Then tossed the cheesecloth.

    I'm a bit biased as I used to work for Doosan, but it's a great machine that can "mill" as good as it can drill. We had one in the showroom for a little while and it cooked pretty good. Only downside...

    I had an OLD (early 1960s) Allis-Chalmers stand up and it was rated for 3,000. There wasn't anything that it couldn't lift. I began to wonder where its limits really were.

    On a large machine like that, I would avoid G53 and set a G30 2nd home. Then make sure you G30 U0, G30 W0 on separate lines so the turret clears the steady rest and tail stock.

    They want your information and also many times are eager to avoid too much comparison shopping. I've bought dozens of used machines. If a dealer didn't list prices I got a little suspicious. Many...

    I had a Takisawa VMC and it was an excellent machine. In the home Country, Takisawa is a very respected name.

    I used to work for Doosan and the machines are a great value. For the money, they're tough to beat. However Okuma is getting VERY competitive with their pricing and the Okuma OSP control is a winner....

    I could not agree more. When I started my shop the very first thing was a VMC. Then a CNC lathe. No way could I have gotten the work without them.

    As far as your experience with other machines, I...

    Transformer. If possible. I have a 10hp piston compressor and it's so loud I usually don't run it at all unless I absolutely have to. As far as "too much," - it's like dollar bills, coffee, and your...

    Whatever you do, don't hold it in the summer. My uncle did that and the turnout was terrible, and prices were way down.

    It sounds like the D.O.C. on the Hurco is greater than the other machines. This will definitely cause lifting of the part. The difference is that the Hurco won't stall.
