Kind Code:
B2
Abstract:
In the method for manufacturing a super abrasive cutting saw, press molds are formed with uneven portions on the main opposite surfaces. The molds define a space portion for containing the periphery of a cutting saw plate. Two masses of compressed sinterable powders are prepared. The two masses of compressed powder are brought to oppose each other while holding the periphery of the cutting saw plate therebetween for engagement. The press molds are engaged to press and hold the masses. Heating the compressed powder to sinter while pressing the same fuses the two masses of compressed powder together and to the cutting saw plate and forms a sinter around the periphery of the cutting saw plate. An apparatus used in the method of manufacturing the super abrasive cutting saw includes the space portion for containing at least the periphery of the cutting saw plate and the pressed powder. The molds defining the space portion are formed with uneven portions on their main surfaces for engaging to the main surfaces of the compressed powder sinter and forming corrugations therein.
