I just bought this machine from a man named Kwong Kim, who had owned it for many years. He had no info about it's origin, only that they had said they "used it to cut aluminum". It is a very sturdy build, of mostly aluminum. It features round-rod steel rails, with 1.594" dia ball bearings riding in groups of three, the X drive and Y drive are steel gear racks, driven by steel pinion gears. The pinion gears are driven by toothed belts with matching aluminum gear pulleys. The Z axis is driven by a ballscrew. The table features aluminum T Slots for hold down of material. Please take a look at the photo, and chime in with your guess, (if you recognize the machine). Thanks!
