Concrete Floor Milling is the bulk removal of concrete (between 5mm and 50mm deep) from a concrete floor. Concrete milling machines leave a coarse texture that is suitable for relaying tiles. The consumables that are used in concrete milling are Tungsten Carbide Cutting Teeth, which are inexpensive and widely available.
There are a number of reasons concrete floors are milled. The first is if the concrete slab is in poor condition and require the top 5mm to 25mm removed as a part of flooring restoration. After the floor is milled there are a number of processes that the contractor can follow with. Contractors can lay tiles directly onto the milled texture. The can also grind the milled texture in preparation for epoxies/resins/coatings.
