Heidenhain: Position Display Units (ND 1200R)

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 1200 R RADIAL-DRILL digital readout | Digital readouts for conventional and fast radial drilling machines

The ND 1200 R RADIAL-DRILL digital readout is an easily operated, powerful position readout for conventional and fast radial drilling machines. Machine movement is measured by a linear encoder on the radial arm and a rotary encoder or a friction-wheel system on the column. An additional encoder on the sleeve can also be used to measure and display the drilling depth.

Design

The ND 1200 R RADIAL-DRILL digital readout features a sturdy housing of die-cast aluminum and a splash-proof full-travel keyboard. The monochrome fl at-panel graphic display shows position values, plain language dialog and prompts as well as graphic functions.

Functions

With the ND 1200 R digital readout, you can switch at any time between display in polar coordinates (radius R, angle ) and Cartesian coordinates (X, Y). With the aid of the probing functions you’ll find the workpiece datum and orientation faster. One essential working aid is the function for positioning with the distance-to-go display: You type in the nominal position— i.e. the drilling coordinates—as X,Y values; the RADIAL-DRILL digital readout shows you the distance remaining to the target position as separate values for the angular and radial axes, which are therefore the machine coordinates. The ND 1200 R automatically calculates the positions when machining hole patterns such as bolt-hole circles and linear hole patterns, matrices or frames. The programming function of the ND 1200 R supports you when machining recurring workpieces and machining patterns.

Interfaces

The RS-232-C/V.24 and USB serial interfaces serve for saving programs and updating software.

Equipping a radial drill

The angular position of the radial arm is usually measured with a rotary encoder and friction wheel system or—for higher accuracy requirements—with an ROD angle encoder or rotary encoder. The drill head position and, if required, the spindle stroke are measured with LS linear encoders. The KT edge finder serves for an exact calibration of the machine and, if desired, to set up the workpiece.
