Tianli Bowl-Type Wet Polishing Pad：

The abrasive layer has a prominent convex curvature, providing a larger and more conforming contact area with convex stone surfaces compared to standard flat pads, greatly improving grinding efficiency

Covers a complete sequence from coarse grinding (50#) to fine polishing (3000#). It removes scratches step by step and ultimately restores a mirror-like high gloss to convex stone surfaces

The spiral/grid texture design effectively channels water flow, accelerating cooling and debris removal during wet grinding, preventing scorching or cracking caused by overheating
