How Linear Encoders Can Help Improve Precision Machining Tools

Tools for precision machining have improved immensely through the use of linear encoders. This is a sensor, readhead, or transducer that works with a scale. Linear encoders can determine positioning.

How Encoders Work

A magnetic linear encoder works by reading the scale connected to it. Then it converts the position to a digital signal. A digital readout can then decode it into a position. Precision machine tools such as digital calipers can use these tools. Coordinate measuring machines also use these calipers. There are many different physical properties that can encode the position. These include inductive, optical, capacitive, and magnetic.

Types of Encoders

The most popular type of encoder is the optical linear encoder. Precision machining tools especially use these encoders. A typical optical linear encoder has a scale that can vary from just a few microns to hundreds of them. This is a very accurate and precise type of scale. This is why it is one of the most commonly used types.

A magnetic linear encoder is another common type of encoder. This model works with one of two types of scales. The first type is active and magnetized. The passive type is reluctance.

What to Use Linear Encoders For

There are two main applications of tools from linear encoder manufacturers. These are measuring and motion systems. Precision machining tools can especially benefit because the measurement is even more important. Everything needs to be accurate to the hundredth of a millimeter.

Many coordinate measuring machines use linear encoders for measurement. Gear measurement, calipers, laser scanners, and digital readouts also all use encoders. The motion systems from a linear encoder can also benefit precision machining. This is because they offer accurate movement at high speeds.

Choose the Right Type of Encoder for Your Business

A laser encoder is either open or closed. Each one has its own benefits and drawbacks. An open encoder may get dirty, especially in a precision machining tool. However, it tends to be more accurate because there is not as much friction. An enclosed encoder produces more friction because of the enclosure. You should consider each of your machines before deciding which type is right for your company. One of the best linear encoder manufacturers can help you.
