The invention relates to a grinding machine, which is suitable for a robot-supported grinding process. According to one embodiment, the grinding machine has a housing, a motor arranged in the interior of the housing, a fan wheel arranged on a motor shaft of the motor in the interior of the housing, and a support plate coupled to the motor shaft for receiving a grinding disc. The support plate has openings for intake of grinding dust into the interior of the housing. The grinding machine furthermore has an outlet arranged in a wall of the housing for exhausting the grinding dust out of the interior of the housing and a non-rerun valve arranged in the wall of the housing. The non-return valve enables an to escape from the interior of the housing, but prevents intake of air into the interior of the housing.

The invention relates to a screening element for screening and transporting grit material, for applying to a sanding device of a sanding apparatus for a vehicle. The screening element includes a plate element provided with a shaft-coupling mechanism, at least one through-opening, and at least one lug. The shaft-coupling mechanism is designed to couple the screening element to a shaft device of a rotary feeder of the sanding device. The through-opening is arranged in the plate element and is designed to guide grit material through the plate element. The lug extends transversely in relation to a main surface of the plate element, away from the plate element.

A grinding apparatus includes a rotary table, multiple chuck, a rotational driving unit, a grinding position cover, a cleaning unit and an attachment/detachment position cover. The horizontal rotary table is configured to be rotated around a vertical rotation center line. The multiple chucks are arranged at an equal distance therebetween around the rotation center line of the rotary table. The rotational driving unit moves the chuck between an attachment/detachment position and a grinding position. The grinding position cover covers the grinding position from above and from a side. The cleaning unit is configured to supply a cleaning liquid to the chuck or the substrate at the attachment/detachment position. The attachment/detachment position cover covers the attachment/detachment position from above and from a side. The attachment/detachment position cover is provided with a transfer opening for the substrate in a side surface thereof, and accommodates therein the chuck and the cleaning unit.
