Cup grinding wheel-electric spark composite trimmer for superhard abrasive grinding wheel

Abstract

The invention discloses a cup grinding wheel-electric spark composite trimmer for a superhard abrasive grinding wheel. The cup grinding wheel-electric spark composite trimmer comprises the grinding wheel, a hollow spindle, a conducting slip ring and a motor. The grinding wheel is connected with the hollow spindle, and the conducting slip ring is fixed into the hollow spindle. In shaping, the grinding wheel is fixedly arranged on a fixing disc located at one end of the hollow spindle and used for shaping a target object. After shaping is completed, in sharpening, the abrasive wheel is replaced by a red copper electrode, and the red copper electrode is connected with the conducting slip ring and conducts electric spark trimming on the target object. The motor is connected with the hollow spindle and drives the hollow spindle to rotate. The cup grinding wheel-electric spark composite trimmer integrates a cup grinding wheel trimming method and an electric spark trimming method, and overcomes the defects that shaping and sharpening can not be conducted at the same time in a common trimming method and abrasive particles are passivated after trimming. The trimmer is provided with a pipe screw hole, and the pipe screw hole is connected with a quick coupling. Air is led to the trimmer through an M6 air pipe in work, and the blowing and cooling effect and the waterproof effect are achieved.

Description

technical field [0001] The invention relates to the field of grinding wheel dressing, in particular to a superhard abrasive grinding wheel cup grinding wheel-electric spark composite dresser. Background technique [0002] Diamond and cubic boron nitride (CBN) grinding wheels are collectively referred to as superabrasive grinding wheels. Diamond grinding wheels are suitable for grinding hard, brittle, non-ferrous metals and hard alloys, optical glass, ceramics, gemstones and other high-hardness, high-brittle non-metallic materials. Dressing technology of superabrasive grinding wheel is a new field of dressing technology. Since the development of dressing technology, dressing tools have formed a rich series of families. Many new dressing tools are high-tech products. The development of dressing technology tends to be high-precision, efficient and automated. , has brought a new topic to the dressing of superabrasive grinding wheels. [0003] At present, the commonly used trim...
