What is a DRO?

Understanding Digital Readout Systems

A DRO (Digital Readout) System is an electronic measuring system used on machine tools such as milling machines, lathes, boring machines, grinding machines, and CNC retrofit machines. It shows the exact position of machine movement on a digital display, improving accuracy and reducing manual measurement errors.

Main Parts

DRO System Components

Digital Readout (DRO) System consists of several important components that work together to provide accurate machine position measurements.

1. Display Unit (DRO Console)

• Main digital display screen
• Shows X, Y, Z axis positions
• Supports metric (mm) and imperial (inch) measurements
• Includes zero setting, PCD, calculator, and memory functions

2. Linear Scale (Encoder)

• Mounted on machine axes
• Measures exact movement of the machine table
• Available in different lengths based on machine size
• Can be glass scale or magnetic scale

3. Reader Head

• Attached to the linear scale
• Reads movement from the scale
• Converts movement into electronic signals
• Sends position data to the display unit

4. Mounting Brackets

• Used to securely install linear scales and reader heads
• Custom-designed according to machine type
• Ensures proper alignment for accurate measurements

5. Signal Cables

• Connect reader head to the DRO display
• Carry measurement signals from scales to display unit
• Shielded cables for noise-free transmission

6. Protective Cover & Power Supply

• Protects scales from coolant, dust, chips, and oil
• Increases system life and reliability
• Power supply provides electrical power to display unit
• Usually operates on standard AC power
