Description

Technical Field

[0001] This utility model relates to a fully automatic grinding wheel dressing machine, belonging to the field of mechanical technology. Background Technology

[0002] During grinding, the abrasive grains of the grinding wheel gradually wear down, leading to a decrease in its cutting ability. The worn surface of the grinding wheel becomes dull, affecting machining quality and efficiency. With increasing industrial demands for high-precision and high-efficiency machining, regular grinding wheel dressing has become a crucial step in ensuring machining quality. Dressing the grinding wheel restores its cutting ability and ensures the shape accuracy and surface roughness of the workpiece. Traditional manual dressing methods rely on the operator's experience and skill, making it difficult to guarantee the accuracy of the dressed wheel. Furthermore, manual dressing is inefficient and cannot meet the demands of modern industrial high-efficiency production. Manual dressing makes it difficult to precisely control the dressing angle, easily resulting in the grinding wheel surface shape not meeting machining requirements, affecting machining accuracy. In addition, the ease of assembly and disassembly of the grinding wheel and the precision of the mechanism are also crucial. CCD image assistance is also necessary when dressing the grinding wheel in circular arcs. Utility Model Content
