    摘要： A sander includes an airflow element rotatable about a central axis along a preset direction of rotation to generate a dust removal airflow; an electric motor for providing a power source for the airflow element; and a battery pack for providing an energy source for the electric motor. When the sander is in a load-free state, the working duration of the sander when the battery pack consumes 10 WH of energy is defined as the functional time T of the sander; and the product of the load-free rotational speed N of the electric motor and the functional time T of the sander is greater than or equal to 63000 rpm·min and less than or equal to 120000 rpm·min.

    摘要： An orbital sander includes a housing, a drive unit within the housing having an electric motor defining a rotational axis, and a drive shaft coupled for co-rotation with the motor about the rotational axis having a fan rotatably coupled to the lower portion of the drive shaft. The fan includes a main body having a plurality of fan blades, an upper counterweight located on one side of the main body and a lower counterweight located on an opposite side of the main body for balancing the operation of the fan, and an interruption region located opposite the lower counterweight with fan blades located within the interruption region having a reduced mass. The orbital sander further includes a baseplate for selectively mounting a sanding sheet that is coupled to the lower portion of the drive shaft for orbital rotation about the rotational axis.

    摘要： Grinding chips generated during metalworking are collected, and dust is collected using a dust collector. A metalworking dust collection attachment removably attachable to a grinding tool including a tip tool includes a suction port that collects grinding chips generated during grinding with the tip tool, and a collector connected to the suction port to collect the grinding chips sucked into the suction port. The collector cools the grinding chips.

    摘要： A surface processing device, in particular a manual grinding device, includes a processing body which has at least one processing surface for grinding or polishing a workpiece surface, wherein inlet openings are arranged on the at least one processing surface for suctioning off dust-laden dust air and these inlet openings are flow-connected via a duct arrangement to a suction connection to which a suction device can be connected. The surface processing device is provided with an adjustment means for adjustment of effective flow cross-sections, with which inlet openings of a first processing surface section of the at least one processing surface and inlet openings of at least one second processing surface section of the at least one processing surface are flow-connected to the suction connection, so that a suction effect on the first processing surface section and the at least one second processing surface section can be set and/or switched off.
