  • Minimum concrete thickness for 19 000lbs CNC

    Oct 27 2008 · A 19 000lb machine probably wants at least 2 feet of concrete under it. A rule of thumb is the concrete foundation should be five times the machine s mass. I make that about 40 tons of concrete if you know the footprint of your machine then you can work out the thickness. Sure as hell it s more than 6 inches.. Regards Mike
