Heidenhain: Position Display Units (ND 500)

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 500 Series | Simple position display unit for two and three axes

The position displays of the ND 500 series are suited for use on manually operated milling, drilling, boring machines and lathes with two or three axes. Due to the TTL encoder input, primarily the LS 328 and LS 628 linear encoders with a measuring step of 5 µm are used.

Design

With its sturdy housing and splash-proof membrane keyboard, the ND 500 is built for the workshop. The ND 500 series shows display position values, the soft-key row and other useful information on a monochrome graphic screen.

Functions

The most important functions are available quickly and directly via function keys. Soft keys with clear information in the local language enable you to make entries that fi t your momentary situation.

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).

You can easily switch between radius and diameter display when the position display is configured for turning. On lathes with a separate top slide, the sum display feature of the ND 523 allows you to display the saddle and top slides together or separately. Setting datums on a lathe part is particularly easy with the freeze tool position function and subsequent retracting.

Data Interfaces

A USB interface enables the digital readout to transfer measured values and import or export parameters and tables.
