5 Factors To Consider When Choosing A Digital Linear Scale

The digital linear scale is important for measuring the linear motion of the machine tool in a wide variety of machines such as milling machines and lathes. While they have numerous advantages such as accurate measurement and durability. However, all digital linear scales are not created equal. In this blog, Walker Machinery Inc., a leading supplier of DRO systems, explores 5 factors to consider when selecting a linear scale for high-performance applications.

How To Select A Digital Linear Scale?

Thermal Fluctuations

During high-speed machining processes, it is not uncommon for the machine tool or the workpiece to reach high temperatures. This also causes it to expand and contract during these temperature fluctuations. A well-designed linear scale must also match the temperature changes of the tool and expand and contract accordingly.

Rigidity

When the DRO unit is measuring the tool travel length in a particular direction, then it must be rigid enough to accurately provide the reading of the path.

Mass Of The Moving Components

Another factor that will determine the accuracy of the linear scale is the mass of the moving components. Since most tools have a low moving mass, it helps to enhance the accuracy and rigidity of the digital linear scale.

Durability

The linear scale must be durable enough to handle high-performance applications on a long enough timeline for the best returns. Heidenhain digital linear scale offers this durability as well as stability.

Environmental Factors

Some encoders must be designed for extremely specific environments, such as high and ultrahigh vacuums. Thus, the selection criteria for a linear scale will change in such circumstances.
