摘要： PURPOSE: To reduce danger of generation of grooves at the time of grinding, and assure favorable absorbing action. CONSTITUTION: This grinder has an oscillation shaft 24 to drive a grinding tool 12 about an oscillation axial line 14 fixed to a plate, and the grinding tool 12 has a grinding surface 16 and at least one angle range 18. A suction hood 20 to suck grinding dust is provided to be fixed on the plate, and a suction nozzle 22 is communicated with this in a lateral direction. For reducing danger of generating grooves in precision machining a surface, and assuring effective suction of grinding dust, the grinding surface 16 is composed as a closed surface without having a hole, the suction hood 20 surrounds the grinding tool 12 from above, and it encloses a side surface 34 of the grinding tool 12 at least partly. The suction nozzle 22 is communicated with the suction hood 20 in a lateral direction in a range apart from the angle range 18 of the grinding surface 16. In addition, a suction chamber 28 is provided in the suction hood 20, and the suction chamber is extended from the suction nozzle 22 to the angle range 18 of the grinding tool 12.

摘要： A sanding device (10), in particular for the vibrational sanding of the surface of a tube (25) or the like, has a retaining element (12) which is formed with an at least approximately half-round, cylindrical opening (18), on the inside of which fastening means are provided for holding the sanding tool in place. To this end, a hollow body (14) forming the opening (18) is fastened to the retaining element (12), and a velcro-type lock strip (16) is attached as fastening means for the sanding tool to the inside of the hollow body (14). An abrasive paper likewise provided with a velcro-type lock can be detachably fastened by means of the velcro-type lock strip (16). In addition, the retaining element (12) is dimensioned in accordance with the sanding plate (23) of a portable sander (20) and has on its underside a velcro-type lock tape (12') which can be fastened to the sanding plate (23). With this sanding device according to the invention, workpieces such as tubes, sections, squared timber or the like can be sanded down, cleaned, polished or even roughened in a very simple and efficient manner.

摘要： PURPOSE:To obtain the various movements of a grinding paper matched with the shape or material of the member to be ground, by presetting plural pads on which engaging hole or groove in various shapes are formed, and installing these with their selection adequately. CONSTITUTION:A pad guide 20 which extends in the direction orthogonal with the rotating axial line of a rotary shaft, as well as being supported turnably around the axial line parallel to the rotary shaft 10, a displacement allowable means which allows that a pad base is displaced in the direction apart from an eccentric shaft 18, and a pad 22 with plural grinding papers having an engaging hope 27 or engaging groove engageable and disengageable for the eccentric shaft 18, as well as being fitted slidably and changeably to the pad guide, are provided on a main body. In this case, the plural pads 22 are formed in different shapes respectively at its engaging hole 27 or engaging groove, those pads are selectively fitted to the pad guide, and worked with the grinding motion in the form corresponding to the shape of the engaging hole enagaed with the eccentric shaft.
