| What is Barrel finishing? |
| |
Barrel finishing is a surface conditioning operation in which a mixture of metallic or non-metallic parts,
abrasive media, and various compound, is placed in a rotating drum (called the Barrel”).
As you choose proper barrel grinding stone according to quality, shape, size and grinding purpose, you can
experience the best grinding effects, cost-down and elevation of goods. |
| |
| The purpose of Barrel stone |
| |
* To descale after formation & rounding corners.
* To eliminate the scars after heating.
* To improve surface finish for polishing.
* To grinding before plating and coating.
* To burnish for low micro inch finishes.
* To eliminate scars and burrs. |
| |
| Use of the barrel grinding stone |
| |
Barrel finishing methods may be applied successfully in many plants, large or small, to replace costly handfinishing operations on either metallic or non-metallic parts such as iron, steel, stainless steel, brass, bronze, copper, aluminum, zinc, magnesium, many of the rare metals and most alloys in common use, including the newer high temperature alloys, and plastics. |
| |
| All manufacturing processes are applicable |
| |
Including stamping, forging, coining, sand mold casting, die casting, permanent and
plastic molds, parts machined by milling, screw machine, shaper, drills, and all others. |

| CAUTIONS OF BARREL GRINDING |
| |
1. Choose the machine according to the kind and size of the processing materials.(rotating, vibration,centrifugal)
2. Choose the quality and size of the barrel grinding stone according to the size and hardness of the processing materials.
3. Choose the quality of the barrel grinding stones according to the shape of processing materials. (R-type, D-type, T-type, B-type, C-type, X-type, etc.)
4. Choose the quality of the barrel grinding stones according to the usage of processing. (heavy, medium, light, fine, ultra- fine, etc.)
5. Properly adjusting the quantity of the stone and additional materials in the container, so that can be reduced rates of inferior and increased grinding effects and brilliant capability.(reduce water rate in heavy grinding and increase for fine finishing.)
6. Use correct compound and rate of compound to have more grinding effect. |
