Abstract

The invention belongs to the field of grinding wheels and manufacturing method thereof and particularly relates to a corrugated roller grinding wheel and a manufacturing method thereof. The grinding wheel is characterized in that raw material component and weight percentage of grinding parts are that 68-80% of grinding materials with granularity of 36 [mu]m-120 [mu]m; 8-15% of ceramic bond; and 10-15% of pore-forming materials. The manufacturing method comprises following steps of 1) mixing materials; 2) forming; 3) drying; 4) kiln placing; 5) sintering; and 6) blank drying and size processing. The grinding wheel is advantageous in that the grinding wheel is high in rotation strength, rigidity, structure uniformity, static balance performance, heat radiation performance, grinding performance, grinding efficiency and grinding precision.

Description

technical field [0001] The invention belongs to the field of grinding wheels and manufacturing methods thereof, in particular to a grinding wheel for grinding corrugated rollers and a manufacturing method thereof. Background technique [0002] The corrugating roll is the most important part of the corrugated cardboard production equipment. It has a large diameter (up to 280 to 600mm) and a long length (1.6m to 2.5m), making it extremely difficult to grind. In recent years, in order to improve the grinding accuracy and grinding efficiency of corrugated rollers, some enterprises in the domestic packaging machinery industry have successively introduced some CNC grinding machines for corrugated rollers with high grinding efficiency and grinding precision from Germany, Japan and other developed countries. The wear resistance of the corrugated roll avoids the occurrence of dents or pits due to uneven wear during use, which affects the processing accuracy and service life. The mate...
