Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, specifically a shaped grinding wheel. Background Technology

[0002] The watch industry is currently driven by technological advancements (enabling the creation of complex curved surfaces while ensuring strength and light transmission), visual upgrades (enhancing the three-dimensionality, layering, and light refraction effects of the dial, thereby increasing visual impact and brand recognition), functional needs (better accommodating complex raised movements, etc.), and market demands (showcasing craftsmanship and high-end positioning, satisfying consumers' pursuit of personalized, unique designs and retro / futuristic aesthetics). As a result, the industry is increasingly demanding 3D watch covers.

[0003] To produce 3D watch cases, an essential process is hot bending, which transforms the product from 2D to 3D. However, due to the limitations of this process, it cannot fully meet the needs of customers for watch cases with varying thicknesses, and defects such as mold marks may exist on the surface of the formed watch case. Therefore, a subsequent process, CNC precision carving, was developed. This process uses a diamond grinding head to perform fine machining on the three-dimensional curved surface of the glass, using vacuum adsorption fixtures for fixation, and the cutting tool moves spirally from the outside to the center.

[0004] Currently, CNC grinding wheels are integrated round nose cutters. They use different separate structures to process and cut the outer surface of the product's surface multiple times. This grinding wheel solution has a small contact area when processing the outer surface, requires multiple cuts, is inefficient, and produces vibration marks (grinding wheel lines). Utility Model Content

[0005] The purpose of this utility model is to provide a shaped grinding wheel to solve the above-mentioned technical problems. The shaped grinding wheel of this utility model is provided with a flat grinding tool, a contouring surface and a cutting fluid tank. The flat grinding tool is used to repair the product platform, the contouring surface is used to repair the outer surface of the product, and the cutting fluid tank can ensure the cooling of the grinding wheel when repairing the product surface. In this way, when processing the product, there is no need for multiple Z-axis lifting and lowering, which improves the product efficiency. In addition, the contouring surface is adapted to the outer surface of the product, which is not easy to produce tool marks and improves the surface aesthetics of the product.
