|
| Machine configuration |
• Copper vapor laser (CVL) “Kulon-15”
• PC-based travel and control system
• Technological chamber
• Optical system of delivering and focusing the beam in the treatment zone
• System of gas supply into the treatment zone
• System for destruction products removing from the treatment zone
|
| Advantages |
Technological:
• High precision of treatment
• Higher productivity than that of electrospark discharge machines
• No splitting of materials
• Small size of the processing spot
• Contactless treatment
• Low defect area
• High reproducibility
• Evaporative nature of treatment (minimum liquid phase)
• Low roughness of the cutting edge
Structural:
• Long service life and possibility of express active elements replacement
• Simple adjustment of the machine
• High repeatability of the active element parameters
• Laser system of observation using the same active element
