Touch Probe

HEIDENHAIN has been developing touch probes for workpiece and tool measurement on machine tools for over 30 years now. It has set standards, for example, with

• its wear-free optical sensor,
• its integrated flusher/blowers for cleaning the measuring point,
• its SE 540, which is the first transceiver capable of being fully integrated into the spindle housing, and
• its collision protection for the TS 460 touch probe.

As a matter of course, many years of experience feed into the continuous development of these products. Numerous improvements have made working with the touch probes easier, more reliable, and ultimately more efficient for the operator.

Wear-free optical sensor
Because the optical sensor is free of wear, it is able to provide the specified probe repeatability even after a large number of probe measurements (over 5 million switching cycles). This means that touch probes from HEIDENHAIN are also excellently suited for grinding machines.  The optical sensor features an optimized lens system and an integrated preamplifier for stable output signals.

Reliable measurement results
Clean measuring points are a prerequisite for high process reliability. That is why all TS workpiece touch probes from HEIDENHAIN have flusher/blowers for cleaning the workpiece, either by means of coolant or compressed air.

Collision protection and thermal decoupling (option for TS 460)
Collision protection is a major topic at HEIDENHAIN. The touch probes feature a sizable deflection path and offer additional safety through rated break points in the stylus and in the connecting pin for the probe contact. For expanded collision protection, including for the touch probe housing of the TS 460, HEIDENHAIN offers an optional mechanical adapter between the touch probe and the taper shank. In the event of a light collision against a fixture or workpiece, the touch probe can absorb the shock. At the same time, the integrated switch deactivates the ready signal, and the control stops the machine. Furthermore, the collision protection adapter functions as a thermal decoupler, which protects the touch probe from being heated by the spindle.

EnDat for touch probes
The TS 460 and TT 460 touch probes support the EnDat output interface for touch probes. In addition to delivering the triggering status, the EnDat interface provides the control with various additional data and diagnostic capabilities. As a result, connection to the TNC is particularly convenient, and daily operation is even more reliable.

Grid encoder:

Measuring devices for inspection of linear axes

KGM 181, KGM 182, KGM 281, KGM 282 – grid encoders

The KGM grid encoders consist of a grid plate with a waffle-type graduation, which is embedded in a mounting base, and a scanning head. During measurement, the scanning head moves over the grid plate without making mechanical contact. The KGM encoders capture any motions in a plane and separately transmit the values measured for the two axes.

Area of application
The KGM encoders dynamically test the contouring accuracy of controlled machine tools. For example, they make circular

interpolation tests possible with radii ranging from 115 mm down to 0.1 mm at feed rates up to 80 m/min. Especially at very small radii, the errors resulting from the machine’s geometry no longer have an influence on the measurement results. The contact-free scanning also permits free-form tests over any contours in two axes.

Measuring setup
For setup, the mounting base is fixed onto the workpiece-holding element (such as the machining table) and aligned to the axes. The scanning head is mounted on the tool-holding element (for example, the spindle of a machining center) so that it cannot rotate and is also approximately aligned to the axes. An adjustment plate is included in delivery for simple adjustment of the scanning gap to 0.5 ±0.05 mm. The setting screws of the scanning head are then used for the fine adjustment. They are used to optimize the measurement signals displayed in the ACCOM evaluation software.

PMT 9

PROGRAMMABLE MULTIFUNCTION TRANSDUCER

Description :
The PMT-9 Multifunction Programmable Transducer measures the several variables of an electric power system and processes them to produce 4 analog output signals. 2 digital output signals are available for signaling the limits. The limits of the outputs can be set by individual measurand or logically combine up to three measurand. The principle of measuring is Dedicated DSP Controller for best calculation of RMS values and Power.

The PMT-9 is equipped with USB serial port interface through which using the corresponding software one can connect, program, or access and execute useful ancillary functions. The ancillary functions include a power system check, provision for displaying the measured variably on a PC monitor, the simulation of the outputs for test purposes.

The PMT-9 is also equipped with a RS 485 bus interface (MODBUS®). The RS 485 interface enables the user to determine the number of variables to be supervised (up to the maximum available). The levels of all internal power/ energy meters that have been configured can also be viewed. Provision is made for programming the PMT-9 via the bus. A standard EIA 485 interface can be used, but there is no dummy
