The following video shows the visual effects of a 4mm-thick 304 stainless steel sheetplate after tumbling finish.

The tumbling process (or tumble finishing) is a mass-finishing method used to smooth, polish, deburr, or clean metal, plastic, and stone components. It involves rotating or vibrating parts inside a container with abrasive media, water, and compounds, causing the media to erode surface defects and create a refined finish.

Key Aspects of the Tumbling Process:
1️⃣Mechanism: Parts and abrasive media (such as ceramic, plastic, or steel) are placed in a container. The tumbling action (rotation or vibration) forces the media to rub against the parts, smoothing edges and polishing surfaces.
2️⃣Process Types:
1) Rotary Barrel Tumbling:
Uses a rotating horizontal barrel for gentle processing or, with higher speeds, to create significant surface reduction.
2) Vibratory Finishing:
A more efficient method where a tub vibrates, allowing for faster, more uniform treatment of parts, including, delicate, complex, or heavy parts.
3) Centrifugal Barrel Finishing (CBF):
A high-energy method used for fast processing of large quantities of parts.
3️⃣Steps: The process usually includes loading the container, adding water and specific abrasive media/compounds, running for a predetermined time (minutes to 24+ hours), rinsing, and sometimes polishing or burnishing.
4️⃣Materials: Suitable for a wide range of materials, including stainless steel, aluminum, brass, bronze, titanium, and stones.
5️⃣Purpose: Primarily used for deburring (removing sharp edges), radiusing, descaling, burnishing, and polishing.

— Tumbling process is a metal surface finishing process in which a metal surface becomes burrs-free, smooth, and gets a uniform finish.
— The tumbling is a process formed by 4 different steps: grinding, smoothing, polishing and shining. The purpose of the tumbling process is obtaining a shiny and and flat surface without flaws, resulting in smooth, polished components.
