Heidenhain: Position Display Units ND 280

Digital Readouts for Manual Machine Tools

Digital readouts for manual machine tools increase your productivity. You save time, increase the dimensional accuracy of the finished workpiece and enjoy user friendly operation. It plays no role whether you have equipped a new or used machine with a digital readout. HEIDENHAIN digital readouts can easily be retrofitted to any model of machine or type of equipment, whatever the application and number of displayed axes. Practice-oriented functions and cycles are available for various applications. The distance-to-go display feature with graphic positioning aid allows you to approach the next nominal position quickly and reliably simply by traversing to a display value of zero. And POSITIP speeds up small-batch production—repetitive machining sequences can be saved as a program.

Precise manufacturing made easy: Together with linear encoders from
HEIDENHAIN, the digital readouts measure the axis movements directly. The
backlash caused by mechanical transfer elements such as lead screws, racks and gears therefore has no influence.

ND 280 | The digital readout for one axis

The ND 280 digital readout for one axis is designed for simple measuring and positioning tasks, such as infeed for a circular saw, the stroke of press travel, or the position of an additional rotary table on a machine tool.

Design

The ND 200 series features a sturdy aluminum die-cast housing. The splash proof full-travel keyboard is built for the workshop. A large graphic TFT monitor displays the measured values, the status and the soft-key row.

Functions

The standard ND 280 readout provides the basic functions for simple measuring and positioning tasks. The ND 287 evaluation unit (see catalog titled Evaluation Electronics for Metrology Applications) offers expanded functions such as metrological acquisition and statistical evaluation of measured values. With its switching inputs and outputs, it also permit operation in simple automated environments.

Data interfaces The ND 280 has serial interfaces for measured value transfer to a PC or printer, for input/output of parameters and compensation value lists, and for diagnostics:
