New!  Rotary Encoders Used for Machine Safety

ECN113 and EQN 1125 absolute encoders for servo drives have been updated to Generation II: ECN 1123 and EQN 1135.

The following improvements have been made:

• Expanded power supply range form 3.6 to 14v
• Enhanced diagnosis options, such as temperature monitoring with an internal sensor, evaluation of the function reserves
• Evaluation of an external temperature sensor*
• Reduction of the interpolation error within one signal period, leading to improvement of the speed ripple.
• Insensitivity to contamination.

Probe Accuracy

The probe accuracy specifies the error resulting from probing a test component from various directions at 20 degrees Celcius ambient temperature. The respective values are listed in the specifications. 3-D touch probes are measured for accuracy on precision measuring machines at the HEIDENHAIN plant.

TS as example:

1. The effective ball radius is taken into consideration in the calculation of the probing accuracy. The effective ball radius is the sum of the actual ball radius and the stylus deflection, including stylus flexing, that is required to produce a trigger signal.
2. Heidenhain has also developed a new generation of test probes which utilized peizolelectric elements which convert into trigger signals.
3. The optical circuitry allows for the reaction time and accuracy of the probe to be more enhanced than the competition.

Heidenhain has released some new probes for machine tool accuracy!

New 3-Touch Probe Systems

TS444 and New Battery Power Adaptations for TS440 and TS640 Touch Probes

Historically Heidenhain also has used "2" 3.6-V lithium batteries for the TS440 and TS640. Now, with improved electronics the TS40 and TS640 can use alkaline batteries between 1V and 4 V.

To take it further: The new TS444 Infrared Touch Probe can be powered by compressed air.

The TS444 functions with compressed air supplied through the spindle of the machine tool instead of battery power. The air is introduced into the touch probe via a taper shank, and powers a turbine wheel inside the touch probe. This wheel generates electrical energy through changes in the magnetic field, which is stored in high power capacitors.

The exited air actually cleans the test probe.

This touch probe is suitable for all uses who are looking for an alternative to battery power. This sensor ensures a probing accuracy of +/-5um and a repeatibility of 2 σ ≤ 1 µm at a probing velocity of 1 m/min.

TS740

Infrared touch probe for higher accuracy and repeatability!

It features a new sensor whose principle function is completely different form that of the optical sensor of the standard touch probes.

This new sensor operates with "3" piezoelectric elements. When probing a workpiece, the stylus is deflected so that a force acts on these elements. This results in the generation of charges that are detected by electronics and are converted into trigger signals.

The probing accuracy is ≤ ± 1 µm and a probing repeatability of 2 σ ≤ 1 µm at a probing velocity of 0.25 m/min. when using a standard stylus.

Now Heidenhains 3-D Touch probes can be used on NC controls from different manufacturers such as FANUC. by using the UTI 192 universal touch-probe interface.

Touch Probes for Machine Tools

3-D touch probes from HEIDENHAIN were conceived for use on machine tools – in particular milling machines and machining centers. 3-D touch probes help to save costs in the workshop and in medium-size production runs: NC controls can automatically run setup, measuring and verification tasks – and most controls can also run them under program control.

Measuring Workpieces

The stylus of a TS three-dimensional touch trigger probe is deflected upon contact with a workpiece surface. This releases a trigger signal in the TS that is transmitted to the control either through a cable (TS 220 and TS 230) or as an infrared light signal (TS 640 and TS 440). The control simultaneously saves the actual position values as measured by the machine axis encoders, and uses this information for further processing.

Measuring Tools

With the TT 140 three-dimensional triggering touch probe, the contact plate is deflected from its rest position, sending a trigger signal to the NC control, during probing of the stationary or rotating tool.

The TL laser systems operate without any contact. A laser beam probes the length, diameter or contour of the tool. Special measuring cycles in the NC control evaluate the information.

Endat 2.2 Compliance & Other Safety Measures

Heidenhain has designed a safety architecture incorporating EnDat 2.2 protocal:

Two mutually independent position values and additional error bits in concert with the EnDat 2.2 protocal to the EnDat-Master.

Safety measures include variables for safe stopping, safe controlled stop, reducing speed, safely limited position and safety off.

Heidenhain is the first manufactuer to present safety-related position measuring systems based purely on serial data transmission over the EnDat 2.2 interface for use in safety related applications.
