Heidenhain ND 780 series

Reply

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 fulltravel 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. 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 fi nder. The ND 780 readout supports you with special probing
functions.

You can easily switch between radius and diameter display when the position display is confi gured 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, touch the workpiece and freeze the tool position. Then retract and measure the workpiece.

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.

Heidenhain ND500 series

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.

Description
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 fit your momentary situation. The distance-to-go display facilitates positioning. You approach the next position quickly and reliably by simply positioning 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 confi gured 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
