Benefits of technology
This technology allows an apparatus called Ultrasound Device to clean out worn cutting discs while they are being worked on by create tiny cutouts through them' surfaces instead of damaging their properties during machining processes. It achieves this by removing any residue from these areas before further treatment steps like sand blastings. Additionally, there may have been some other materials left behind after the process if done properly. Overall, Ultimately, this new method provides faster and more accurate methods than traditional ways such as scrapers.
Problems solved by technology
The technical problem addressed in this patented text relates to improving the performance or efficiency of polishing tools during manufacturing processes that require precise control over their dimensions (such as thickness). Specifically, current techniques involve adjustment of the size of the abraded layer being ground, leading to variations between finished products due to differences in crystal structure caused by factors like impurities added into the raw ingredients from previous production steps. Additionally, excessive wear and damage often occurs if these techniques were applied incorrectly without proper consideration given how much they could affect the final product's appearance and functionality.

The invention discloses a device for on-line ultrasonic dressing of a coarse-grained superhard abrasive grinding wheel. Within the time of suspending of grinding machining of the grinding wheel, a detecting device utilizes an angle control encoder to control an industrial camera used for extracting images to rotate, a camera lens scans and takes pictures from the end away from the grinding wheel to the position, perpendicularly close to the grinding wheel, of the camera, then the images are uploaded to a computer and processed through an openCV, and if it is detected that grinding wheel abrasive particles are not subjected to large-area abrasion, the detecting device rotates the camera to get away from the grinding wheel; and if it is detected that the grinding wheel abrasive particles areseriously abraded, machining is suspended continuously, the industrial camera rotates to get away from the grinding wheel, a dressing device moves to the position of the grinding wheel, the coordinates of the contour of abrasive particle abrasion accumulating areas are output, a G code is generated, a tool on an ultrasonic device is controlled to dress on the abraded position, and after dressingis completed, the ultrasonic device moves to the outmost side of a worktable. According to the device, the ultrasonic device is utilized to detect and dress the grinding wheel under the situation of not detaching the grinding wheel, and the machining quality and efficiency of the grinding wheel are improved.
