OptoTech - Model SM 30 CNC-TC -Grinding Machine

• 3 Spindles (Workpiece spindle, 2 grinding spindles)
• Adjustment of the process parameters via 3-axis CNC-Controller
• Two tool spindles: Pre-grinding (ball bearing) and fine grinding (air bearing) with cup type tools or grinding tools with integrated edging
• One workpiece spindle for clamping with chuck or vacuum
• Easy to handle due to a CNC controller for parameter input
• OptoTech user interface, Microsoft Windows

• The ideal low-cost version of an high speed CNC generator
• Ideal for supermicro and endoscopy optics
• Easy handling
• Highest rigidity due to a cast iron stand
• Energy efficient motors: Possible energy savings up to 30% (depending on required power)
