Name

Digital readouts from HEIDENHAIN are used in a wide variety of applications. These include machine tools, infeed axes (e.g. on saws and presses), measuring and inspecting equipment, dividing apparatuses, setting tools, and measuring stations for production control. In order to meet the requirements of these applications, many encoders from HEIDENHAIN can be connected to the digital readouts. The main application for digital readouts with two or more axes is on manually operated machine tools. Whether milling, drilling, boring or turning, the field-proven cycles provide the operator with optimal support. Digital readouts show the current position quickly and clearly, enabling a significant increase in work productivity



HEIDENHAIN DIGITAL READOUTS.
OFFER MANY TYPES OF DIGITAL READOUTS FOR UPGRADE OR RETRO FIT.
IF YOU HAVE A MILLING MACHINE, GINDER, LATHES, BIRDGEPORTS, TOOL PRESETTERS, CMMs, TOOL MAKERS MICROSCOPES, OR OPTICAL COMPARATOR HEDENHAIN HAS THE READOUT CHOICE FOR YOU WEATHER IT IS SINGLE OF MULTPAL AXIS, EVEN TNC CONTROL

HEIDENHAIN digital readouts have universal application: In addition to standard tasks on milling, drilling and boring machines and lathes, they also offer ideal solutions for many applications on machine tools, measuring and testing equipment, and special machines—in fact all machines where axis slides are traversed manually.

ND 287 Single and Dual input DRO for Linear and Angle Encoders:

Heidenhain ND 280 Digital readouts: Single and dual axis DRO
Due to their performance range, the position display units of the ND 200 series are predestined for measuring and inspection stations, but are also intended for simple positioning tasks such as infeed for a circular saw or the stroke of press travel. The switching inputs and outputs of the ND 287 permit operation also in simple automated environments. A large graphic TFT monitor displays the measured values, the status and the soft-key row.

Heidenhain Corporation single, Dual Axis Digital Readouts ND 281 and ND 287 to use with their Digital Length Gages.  These durable steel cased readouts accept multiple types of Heidenhain products including Rotary Angle Encoders preform data collection SPC, Min/Max and TIR functions.  One Unit at a time or gang multiple units together.

FUNCTIONS:
The standard position display ND 280 provides the basic functions for simple measuring tasks. The ND 287 features numerous functions for measuring, processing and statistically evaluating positions, for example sorting and tolerance check mode, minimum/maximum value storage, and measurement series storage. These data make it possible to calculate mean values and standard deviations and display them in histograms or control charts. With its modular design, the ND 287 permits optional connection of a second encoder for sum/difference measurement or of an analog sensor, for example for temperature compensation.
