Bridgeport interact 4 help / advice needed.

I suspect what you are referring to as surface scraping is actually the pattern used to retain oil on one of the mating surfaces of the slide ways. By the time that had worn way you'd be looking at a very badly worn machine. The pattern is added after the slideways have been trued up. Creating them makes no difference to the accuracy of the machine. You will most likely find that the mating surface is unscraped and may also be chromed for wear resistance.

However, it does sound as if it's a good example and despite the damage to the board, everything else looks very clean and tidy.

Thanks Muzzer,

I see. I've tried to be clever and used the logic of what I've read about lathe slideways. It's obviously different on milling machines. Quotes for repairing the board are about 6-700£ My worry is that once repaired/replaced, whatever caused burnout in the first place will damage the board again. Could you be so kind to give me an idea, or even better a link to the new motor drive combo that you'd install in a Bridgeport interact with tnc2500. Also, how easy/difficult would be to replace tnc2500 with something like linuxcnc or equivalent modern cnc setup.

Your help is very much appreciated.
