Description

Technical Field

[0001] The utility model belongs to the technical field of polishing equipment, and more specifically, relates to a polishing equipment and a disc dresser thereof. Background Technique

[0002] A polishing machine performs fine grinding on the surface of a workpiece to be processed through a high-speed rotating polishing disc or polishing wheel, thereby improving the smoothness of the workpiece surface. However, as the polishing process continues, the polishing disc will wear, resulting in different flatness on the surface of the polishing disc. As a result, when polishing the workpiece, the polishing pressure borne by different positions on the workpiece surface is different, leading to low polishing accuracy and quality. Therefore, most existing polishing machines use a disc dressing assembly to perform dressing operations on the surface of the polishing disc.

[0003] Currently, the dressing of the polishing disc is mainly carried out using a large disc dresser, which has a relatively complex structure and low dressing efficiency; moreover, the dressing area is large, making it difficult to perform local dressing. After retrieval, the application case with the Chinese patent application number 2023204861362 discloses a disc dressing assembly of a polishing machine, which includes a tool holder for installing a disc dressing tool and a mounting bracket installed on the body of the polishing machine. A bottom plate is fixedly provided on the upper side of the mounting bracket, a sliding frame is provided on the bottom plate, a lead screw is installed on the sliding frame, the outer end of the lead screw is connected to a motor, and the inner end of the lead screw is engaged with a threaded seat fixedly provided on the bottom plate. The inner end of the sliding frame is provided with a tool holder, and the motor drives the lead screw to rotate. The rotating lead screw drives the sliding frame to drive the tool holder to move along the bottom plate. This application case sets a disc dressing assembly on the body of the polishing machine, and a smaller disc dressing tool can be used to perform local fine dressing on the polishing disc, avoiding too large a dressing area to affect the dressing accuracy, but its disc dressing accuracy still needs to be further improved.
