• variable cutting contours, no restrictions by tools
• compared with conventional milling: Process Factor 2.0
• automatic glass disposal of standard cutouts
• suitable for the processing of laminated glass
• water curtain for the protection of surrounding machine components
• controlled capture of the abrasive sand
• radiant energy is absorbed
• specific water flow in separate tanks
• high edge quality
• seaming spindle for seaming / finishing
