摘要： The invention relates to a grinding wheel capable of detachably connecting abrasive segments to a disc in a sliding manner and individually replacing the abrasive segments. According to the grinding wheel, when the abrasive segment is worn away or inferior as it is used for a long time, it has only to replace the corresponding abrasive segment only. Accordingly, an economical efficiency is high.
The invention also relates to method for connecting an abrasive segment to a disc, and to such an abrasive segment.

摘要： Disclosed is a cutting saw (10) used for cutting concrete, rock, lumber and so on and a method for manufacturing the cutting saw. The cutting saw (10) comprises: a circular body (12) made of a steel material in a predetermined thickness; a plurality of through holes (18) of a predetermined shape penetrating through the body (12); and a noise prevention material (20) made of a nonferrous metal powder and resin, or a nonferrous metal plate and a coupling resin, having excellent malleability and a high melting point, said noise prevention material (20) being filled into and cured in said through holes (18) for absorbing the vibration generated due to the friction in the cutting process and for suppressing the propagation of the vibration, thereby reducing the generation of noise.

摘要： A grinding wheel has a disc having a connection hole formed at a center thereof, to which a rotation axis of a grinder is connected, and a plurality of abrasive segments detachably connected to a surface of the disc. A plurality of fixing recesses are radially formed on the surface of the disc at an interval and fixing protrusions having a shape corresponding to the fixing recess are formed on bottom surfaces of the abrasive segments, so that the abrasive segments are connected to the disc by inserting the fixing protrusions into the fixing recesses. According to the grinding wheel, when the abrasive segment is worn away or inferior as it is used for a long time, it has only to replace the corresponding abrasive segment only. Accordingly, an economical efficiency is high.
