The kiln car grinding machine is build for all different sizes of kiln cars. The kiln car moves in a automatically process into the machine. The machine starts with cleaning the surface. The surface is brushed and sucked off automatically. A scanning system moves over the surface and determines the highest and the lowest point. If the measured value exceeds the admissible tolerance, the grinding aggregate moves to the corresponding position and grinds over the surface.
After grinding the machine moves to the basic position, the clamping and arresting are released ant the kiln car can move outward.
