4 Factors To Consider Before Selecting A Digital Readout System

There is a wide variety of CNC control systems and associated accessories, such as DRO units and digital encoders. When it comes to DRO units, they are known for providing accurate readings about the position of the tool and workpiece across one or multiple axes. But not all DRO units are created equal. So what should one consider when selecting a digital readout system for a specific application? This blog covers this topic in detail.

How To Select A DRO Unit?

1. Accuracy And Resolution

The biggest factor to consider with a DRO unit is its overall accuracy and resolution. This is mainly dependent on the selection of the scale. Other ways in which the accuracy of a DRO system can be compromised are the use of an old or inaccurate controller or missing specific pulses from the scale, which build up to a significant error with time.

2. Ease Of Use

The main purpose of a DRO unit is not only to provide accurate feedback, but also to do so in a simple and effective manner. Therefore, ease of use of the digital readout unit should be a major factor to consider. Thus, it should be easy for new users to grasp and use.

3. Protection Against Conditions

If the digital readout is to be used in a condition where it will be exposed to contaminants such as dust, grime, or moisture, then it must be able to withstand them without compromising accuracy. The best way to ascertain this is by checking the IP rating of a particular DRO unit to see if it offers protection from specific contaminants.

4. Resistance Against Shock And Vibration

While often overlooked, it is vital to consider if a DRO unit can withstand the vibration that takes place during machining. Failing to consider this can lead to quick damage to the unit and would require immediate replacement.
