What is Barrel Polishing?
Barrel polishing involves putting the work (product), media (polishing stone), compound (abrasive), water, etc. into a barrel tank (tank), applying constant rotational motion, stirring, and creating burrs by mutual friction. This is a finishing method that can be used to remove burrs, remove scale, and give a glossy finish. Once the working conditions are determined, a uniform finish with no variations can be obtained at any time, making it suitable for finishing mass-produced products.
Use/Purpose
Chamfering, burr removal, gloss finishing after machining
Chamfering, burr removal, gloss finishing of pressed
products Chamfering, gloss finishing of glass and ceramic products Matting
of plastic products
Removal of scale after heat treatment
After forging and die casting products Deburring,
base finishing before plating and painting,
degreasing, mixing, etc. in addition to polishing
Seven Features of Yamashina Tilting Barrel Polishing Machine
- Efficient tank shape with a long fluidized bed and increased polishing The
double octagonal pyramidal barrel tank has a unique shape to Yamashina barrels, and the triple action of the flowing filler and high pressure ensure that the contents are well mixed, resulting in efficient polishing. and polishing will be done. - Protects the workpiece
The rubber lining inside the barrel tank has sufficient thickness and appropriate hardness, providing excellent durability and protection of the workpiece. - Rational Elevation Device
Gears allow the barrel to be elevated quickly and safely. The elevation can be fixed at any angle, and the barrel tank can be rotated while tilted. - By changing the V-belt with variable speed function
or controlling it with an inverter, it is possible to supplement all the rotational speeds required for barrel polishing. - Reduced work time
The lid can be attached and removed easily and quickly because it is tightened with a toggle handle without the use of tools, making it easy to take in and take out contents and inspect. - Excellent safety and waterproofness
Stable operation is possible simply by placing the aircraft on a level floor. In addition, the mechanical parts are waterproof so that there is no problem even if they are exposed to water. - High durability and low power consumption
The structure is simple, robust, and carefully and precisely designed. It has great durability and rotation is extremely light and smooth, so it consumes less electricity.

Barrel Polishing Guide
| situation | Cause |
|---|---|
| Unable to polish uniformly | 1. Bad shape or rotation of the barrel tank 2. Bad barrel installation |
| It takes time to finish | 1. Rotation is too slow 2. Media is too small 3. Media is clogged 4. Filling amount is too high or too low 5. Too much water 6. Inappropriate selection of compound |
| Causes scratches and dents and becomes deformed | 1. Insufficient filling amount 2. Improper mixing ratio of workpiece and media 3. Too fast rotation 4. Too little water amount 5. Workpiece surface is too rough |
| No gloss on the finished surface | 1. Inappropriate compound 2. Severe dirt on the media or workpiece 3. Too fast rotation 4. Too little water volume 5. The surface of the workpiece is too rough |
