Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to a laser-assisted hollow grinding device. Background Technology

[0002] Laser-ultrasonic vibration combined grinding technology leverages the high energy density of lasers and the microscopic forces of ultrasonic vibrations to effectively improve the processing efficiency and surface quality of hard and brittle materials. Hollow grinding wheels provide better cooling and a more uniform grinding force distribution during the grinding process, further enhancing processing efficiency and surface quality. The combination of laser and ultrasonic vibration technologies further maximizes the advantages of hollow grinding wheels, particularly in the processing of high-hardness and high-brittleness materials.

[0003] High-frequency noise generated by ultrasonic vibration can damage hearing, requiring additional sound insulation measures. Harmful fumes (such as material volatiles) are generated during laser processing, and ultrasonic vibration may cause dust to be suspended in certain materials (such as composite materials containing carbon fibers). Under the combined action of laser and ultrasound, toxic gases may be released, thereby affecting the health of workers. Utility Model Content
