How to Choose the Best Jewellery Polishing Machine?
The Polishing Machine Selection Challenge
Selecting the right jewellery polishing machine can make or break your finishing quality. According to Jewellery Production Today (2024), proper machine selection reduces polishing time by 65% on average. Surprisingly, 72% of jewellers regret their first machine purchase due to incorrect specifications.
Key Decision Factors
• Production volume requirements
• Types of metals polished (gold, platinum, etc.)
• Surface finish expectations
• Available workspace dimensions
• Budget constraints
CNC vs Rotary vs Vibratory: Machine Comparison
| Type | Precision | Best For | Price Range |
|---|---|---|---|
| CNC Polisher | ±0.005mm | High-end pieces | £8,000-£25,000 |
| Rotary Polisher | ±0.1mm | General workshop use | £1,500-£5,000 |

Step 5: Test sample pieces before purchasing
Common Buying Mistakes
• Overlooking maintenance requirements
• Choosing wrong RPM ranges
• Ignoring polishing compound compatibility
• Underestimating workspace needs
