2 Axis Digital Readout DRO Display 8" 38" TTL Linear Scale Encoder Mill Lathe
Applications
This DRO kit is commonly fitted to machines , especially for metal working — lathes, cylindrical grinders, milling machines, surface grinders, boring mills and other machine tools — to allow the operator to work faster and with greater accuracy. Use of DROs is not limited to manually operated machines. CNC machines can usually be switched to manual operation, and in this case a form of DRO is simulated on its control panel.
