What Are the Fundamental Differences Between Laser and Plasma Cutters?
Laser cutters and plasma cutters operate on fundamentally different principles. Laser cutting uses a focused beam of light to cut materials with precision, while plasma cutting employs a high-temperature ionized gas to cut through conductive materials.
Let's break down the key technological differences between these cutting methods:
| 特徴 | レーザーカット | プラズマ切断 |
|---|---|---|
| Working Principle | Focused beam of light melts or vaporizes material | Electrically conductive gas melts material |
| Initial Investment | Higher ($100,000 - $500,000+) | Lower ($10,000 - $100,000) |
| Technology Type | Non-contact cutting | Contact-based cutting |
