Description

(1) Technical field

[0001] The present invention relates to a compound vibration grinding processing device, in particular to a method and device based on ultrasonic high-frequency pneumatic low-frequency compound vibration grinding, which is suitable for edge cutting of coatings coated on complex curved surfaces with relatively thin thickness The processing belongs to the technical field of coating material cutting processing technology and coating processing equipment components. (2) Background technology

[0002] Under the current technical conditions, after the polymer coating material coated on the complex curved surface is completely cured and dried, the hardness is very high and it is difficult to process. It is therefore proposed to process after curing but not before complete drying. However, even in this case, the hardness of the coating material is still relatively large. Using a portable device based on traditional processing technology to process, the cutting f...
