Heidenhain: Scanning Head for Incremental Exposed Encoder 1178645-02 (AK LIP 608)
For very high accuracy

Linear encoders from HEIDENHAIN for numerically controlled machine tools can be used nearly everywhere. They are ideal for machines and other equipment whose feed axes are in a servo loop, such as milling machines, machining centers, boring machines, lathes and grinding machines. The beneficial dynamic behavior of the linear encoders, their high permissible traversing speed, and their acceleration in the direction of measurement predestine them for use on highly-dynamic conventional axes as well as on direct drives.

HEIDENHAIN also supplies linear encoders for other applications, such as:

Advantages of Linear Encoders

Linear encoders measure the position of linear axes without additional mechanical transfer elements. The control loop for position control with a linear encoder also includes the entire feed mechanics. Transfer errors from the mechanics can be detected by the linear encoder on the slide, and corrected by the control electronics. This makes it possible to eliminate a number of potential error sources:

Therefore, linear encoders are indispensable for machine tools on which high positioning accuracy and a high machining rate are essential.

Linear encoders measure the position of linear axes without additional mechanical transfer elements. This eliminates a number of potential error sources:

Linear encoders are therefore indispensable for machine tools on which high positioning accuracy and a high machining rate are essential.

Exposed linear encoders are designed for use on machines and installations that require especially high accuracy of the measured value. Typical applications include:

Mechanical Design

Exposed linear encoders consist of a scale or scale tape and a scanning head that operate without mechanical contact. The scales of exposed linear encoders are fastened to a mounting surface. The flatness of the mounting surface is therefore a prerequisite for high accuracy of the encoder.
