The invention discloses an abrasive belt clamp holder used with scroll saw and using method, and belongs to the technical field of scroll saws. An abrasive belt clamp holder used with scroll saw comprising a pin-free saw blade, wherein a clamp holder main body is connected to each of two ends of the pin-free saw blade, a placement groove matching the pin-free saw blade is provided in an outer wall of the clamp holder main body, a first bolt is movably connected to each of two sides of the outer wall of the clamp holder main body, the pin-free saw blade is disposed between two first bolts, a clamping plate is detachably connected to the top of the clamp holder main body, and an abrasive belt is connected between the clamping plate and the clamp holder main body.

By means of the present invention, a suctioning device (1) for a grinding device (100) and a method for suctioning particles produced at a grinding device (100) are provided. The suctioning device (1) has at least one suctioning channel (2), through which suctioned air can flow, and one first manipulation apparatus (3) arranged in the suctioning channel (2). The first manipulation apparatus (3) is designed to be able to directly or indirectly influence a boundary layer (G), in particular a boundary layer (G) of a circulating grinding element (111) of a grinding device (100), in particular to be able to reach into the boundary layer (G).

A belt grinding apparatus for grinding the tips of rotor blades is supported on a rotating rotor. A casing contains the rotatable rotor. An opening in the casing permits access of a grinding belt into the casing where the belt grinds the tips of the blades rotating past. The belt grinding apparatus is attached at the opening at a parting line in the casing.

A process for cleaning an abrasive belt using an air blade extending continuously over the entire working width, or several segmented air blades, as well as a device which encloses this air blade or these air blades having an extraction hood serving to guide away the dust-laden air. If this device is used for a belt grinding machine equipped with a workpiece vacuum device, the air supply requirements are optimised by use of a diverter to reduce the number of fans.
