Description

Technical Field

[0001] The utility model belongs to the technical field of grinding equipment and relates to a single-spindle double-grinding wheel grinding structure. Background Art

[0002] At present, general linear rail grinding machines use the dressing method to achieve rough grinding and fine grinding, that is, usually a grinding wheel is installed on each of the two spindles, and the two grinding wheels have the same number (same grinding wheel). This makes the grinding wheel bear higher grinding force and heat load during the rough grinding stage, which easily leads to wear or blockage of the grinding wheel surface. When the same grinding wheel is used for fine grinding, the worn and blocked surface cannot provide the required surface finish and precision, which in turn affects the final quality of the parts.

[0003] To this end, our company has developed a single-beam five-axis rough and fine grinding structure, which can greatly improve work efficiency and grinding accuracy by installing multiple spindles, and installing rough grinding wheels and fine grinding wheels on multiple spindles for rough grinding and fine grinding operations. However, the above method makes the grinding structure larger and more expensive. Utility Model Content
