A disc wheel sanding machine includes a disc wheel rotated by a drive shaft. The sanding machine has a dust extraction device with a dust extraction hood comprising an extraction chamber which surrounds the disc wheel. The hood of the dust extraction device ends above the disc wheel bottom, and a closing wall in the form of a bristle ring or such like protrudes from the bottom of the hood and can be positioned on the work piece. The bristle ring only encircles a part of the periphery of the disc wheel and forms a suction slot diverging outwardly toward the front end in the direction of rotation of the disc wheel and is open toward the work piece. The sanding dust is sucked through the suction slot at the disc wheel periphery into the extraction chamber. The rear end of the bristle ring with regard to the direction of rotation closes in on the disc wheel periphery and forms a rear seal for the suction slot. Furthermore the hood comprises a sealing section extending over a portion the circumference which does not seal around the disc wheel, leaving a sealing distance allowing for the disc wheel rotation.

An orbital sander/grinder has on one side of its housing a rotatably mounted disk holder which is brought into orbital motion by means of a drive mechanism that is inside the housing, and is coupled with an eccenter. The eccenter is rotatably mounted on one side in the housing, on the other side in the disk holder, while the rotational axis in the housing is radially offset relative to the rotational axis of the eccenter in the disk holder, but the two axes run parallel to each other. A balancing weight for compensating the unbalance rotates in synchronization with the eccenter. To ensure sanding/grinding with a minimum of vibration, means are provided to compensate for the transverse forces generated by the abrasive and/or cutting forces that are exerted at the eccenter.
