Heidenhain: Position Display Units (ND 780)

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 780 | Adaptable readout for up to three axes

The ND 780 digital readout is especially suited for use on milling, drilling and boring machines and lathes with up to three axes. A separate I/O unit provides switching input/outputs for simple tasks in automation.

Design

The ND 780 digital readout is designed as a sturdy upright unit with splash-proof full travel keypad for use in a workshop. It is equipped with a monochrome fl at screen for position values, dialog and input displays, graphic functions and graphic positioning support.

Functions

The ND 780 readout is characterized by its plain language dialog guidance. The distance-to-go display facilitates positioning tasks. You approach the next position quickly and reliably by simply moving until the display reads zero. The functions for each application are easily activated by parameter input. Special functions are available for producing hole patterns (linear patterns and circular patterns). Datums can be determined quickly and accurately with an edge finder. The ND 780 readout supports you with special probing functions.

You can easily switch between radius and diameter display when the position display is configured for turning. The readout also offers support for lathes with separate top slide: The sum display feature allows you to display the saddle and top slides together or separately. To set a datum, simply touch the workpiece and freeze the tool position. Then retract and measure workpiece with the tool out of the way.

Data Interfaces

The ND 780 has an RS-232-C/V.24 serial interface for measured value transfer to a PC or printer, for input/output of parameters and compensation value lists, and for diagnostics.
