摘要： PROBLEM TO BE SOLVED: To reduce the dust emission accompanied by grinding by extracting the dust inside an extraction chamber provided inside a machine casing through both the perforated holes an the bottom plate and the holes provided on a grinding belt. SOLUTION: During grinding work, air inside an extraction chamber 17 is extracted through both the punched holes of an endless belt 12 in the grinding position and the long holes 18 inside the bottom plate 16 by the dust extraction device connected to the connecting conduit 19 of the extraction chamber 17. The extraction is carried out all over the entire surface of the bottom plate 16. Accordingly, air flows all over the entire grinding surface of the partially fabricated product being worked at present, and the grinding dust cut away is carried with the air, and is supplied to the extraction device through the extraction chamber 17. Thus, the extraction amount of dust discharged to the circumferential part of the grinding machine can be restrained under the regulations of harmful substances. The perforated holes inside the bottom plate 16 is not restricted to the long holes 18, but can be formed in an arbitrary shape such as circular, elliptical, rectangular shape or the like.
