Guidelines for Successful Finishing
Raytech offers quality finishing media and compounds that are designed for optimal performance with our finishing products. We've included the guidelines below to help you to calculate the amount of each type of media you will need. For best results, always use the finishing media recommended for your product.
All of our Finishing Media and Compounds can be found here: Finishing Media and Compounds
1. Acceptable media to part ratio is approximately 70% media to 30% parts.
2. When running conventional medias that require a wet process, be sure to have the correct amount of water and compound. Too much water will hamper the vibratory action thus giving less than desired results, as well as long cycle times.
3. The media and compound should just barely be wet with no standing water. It is recommended to use Raytech’s compound rinsing system to ensure proper dispensing of water and compound.
| Media | Mobilty | Shape Contact Area | Media Shape Retention | Surface Refinement | Process Time 1=long, 5= short | Total Versatility |
| V-Cut Cylinder | 4 | 5 | 5 | 5 | 5 | 24 |
| Cylinder | 4 | 2 | 4 | 5 | 3 | 18 |
| Cone | 5 | 2 | 5 | 5 | 3 | 20 |
| Polyhedron | 4 | 5 | 4 | 5 | 5 | 23 |
| Triangle | 3 | 5 | 4 | 5 | 5 | 21 |
| Pyramid | 4 | 5 | 3 | 5 | 4 | 21 |
| Porcelain Balls | 5 | 1 | 5 | 5 | 5 | 21 |
| Numerical Scoring: 1=low, 5=high. Efficiency is not rated by a high accumulated score. The total score is an indication of the media’s all around versatility. | ||||||

| Media and Product | Amount of Media | |||
| Ceramic (90lbs/cu ft) in a TV-10 (.10 cu ft) | 90 x .10=9 pounds of media. | |||
| Porcelain Balls (125 lbs/cu ft) in an AV-40 (.35 cu ft) | 125 x .35 = 43.75 pounds of media. | |||
| Stainless Steel Balls (300 lbs/cu ft) in an AV-25SS | (.22 cu ft). 300 x .22 = 66 pounds of media. | |||
| Ceramalite (65 lbs/cu ft) in a TV-5 (.05 cu ft) | 65 x .05 = 3.25 pounds of media. | |||
| Plastic (55 lbs/cu ft) in an AV-75 (.75 cu ft) | 55 x .75 = 41.25 pounds of media. | |||
| Plastic (55 lbs/cu ft) in an AV-18 (.18 cu ft) | 55 x .18 = 9.9lbs. | |||
| Dri-Shine III (30 lbs/cu ft) in a Dri-Polisher (.12 cu ft) | 30 x .12 = 3.6 pounds of media. | |||
| Note this is total media capacity only and actual media amounts will vary in direct proportion to the amount of parts being tumbled. (See Basic Guidelines section above.) | ||||
