Description

Technical Field

[0001] The present application relates to the technical field of grinding wheel dressing, and in particular to a grinding wheel dressing device for a two-axis programmable surface grinder. Background Art

[0002] Grinding wheel dressing is a key operation process, which aims to restore the grinding performance and correct geometry of the working surface of the grinding wheel. Timely and correct dressing of the grinding wheel is essential to improve grinding efficiency and ensure grinding quality. After long-term use, the surface of the grinding wheel will gradually wear or become dull, affecting the grinding effect. Therefore, by dressing the grinding wheel, the dull surface layer can be removed, its sharpness and precision can be restored, and the processing quality and efficiency can be ensured;

[0003] The most common dressing method is turning dressing, which uses a single diamond (or a diamond pen or diamond dressing block made of fine diamond) as a tool to turn the grinding wheel. The total dressing amount of the diamond tool is generally about 0.1 mm per side, and it needs to be reciprocated for many times.

[0004] This dressing method often requires the staff to have certain skills. Before dressing, the diamond needs to be installed. Generally, the diamond tool installed on the tool holder is tilted about 5° to 15° in both vertical and horizontal directions, and the contact point with the grinding wheel is 0.5 to 2 mm lower than the grinding wheel axis. During installation, the inclination of the fine steel stone tool and the contact point with the grinding wheel are small, and the installation and adjustment process is relatively complicated, which will make the dressing process longer and the efficiency too low. In addition, since the installation and adjustment are manually adjusted, the adjustment value is prone to error, and the debris generated during the dressing will fall directly on the workbench, and the debris may damage the processed object during the subsequent grinding process. Therefore, a person skilled in the art provides a grinding wheel dressing device for a two-axis programmable surface grinder to solve the problems raised in the above background technology.
