Re: [Emc-users] Plasma

2012/7/2 Daniel Rogge dro...@tormach.com: I was testing in Aluminum, but I think that for a given spindle HP your results would be similar in other materials. If you're on an open loop machine it's preferable to size the motors such that you stall the spindle before stalling an axis motor

Re: [Emc-users] Plasma

Vibration consideration and rigidity are usually more limiting factors in machining than HP. For example, a standard Bridgeport style mill has a 1.5 hp motor. Most formulas give ambitious speed/feed/DOC vs hp based on perfect stability. The forces required to cut are small compared to the forces

Re: [Emc-users] Plasma

Hi Viesturs, If you are mainly planning on cutting aluminum I would suggest looking into oil mist cooling instead of flood coolant. You only need a trace of oil in the mist to act as a lubricant while the air clears the chips and cools the part. It works very well. You can get vegetable based

Re: [Emc-users] Plasma

A few things I learned in hindsight... I should have made the Y axis rails extend beyond the end of the water table enough so the torch head could reach all of the water table. A little more Z travel would have been nice. My slats are not rigid enough to keep thin material from moving when

Re: [Emc-users] Plasma

ps: I have no experience with downdraft tables, and perhaps they are the cat's meow, but I am skeptical that they could work as well as a water table. The amount of force with which the dust is created seems like it would too great to be carried away by a downdraft. But, this is just
