Description of function
The Gripping Force Tester GFT-X allows the measurement of
tension when the chuck or collet is in either static or dynamic
mode. Using a complex array of strain gauges in the measuring
head, the mechanical forces are converted into an electrical signal
and amplified by the integrated electronics. The amplified signals
are transmitted from the measuring head with an integrated
UHF transmitter (433MHz) to the handheld unit to be displayed/
controlled.
Here the current clamping force and, in dynamic mode, the
accompanying number of revolutions of the chuck are displayed.
The handheld unit is equipped with a high resolution TFT display
which shows all important menu items as icons. These icons, which
are self-evidend, and a transparent command structure allows easy
operation also for occasional users.
All items are designated for use in severe workshop, the Handheld
Unit is in addition equipped with a silicon protector and offers
therefore utmost protection against shocks and drop down.

languages:
There are four different measuring head available for the GFT-X.
Two for collets (M1 and M2) and two for chucks (M3 and M4).
The measuring head works according to the following principle:
Via a dedicated arrangement of strain gauges inside the measuring
head, the mechanical forces are converted into an electrical signal
which is amplified by the integrated electronics, transformed into a
digital radio signal via a micro-controller and sent to the handheld
unit. There the data signal is encoded and displayed.
Factory provided the measuring heads are calibrated.
After respectively 12 months a check-up and a recalibration
should take place by the manufacturer.
The date for the next calibration is shown under menu measurement
or marked on the measuring head.

Measuring head M1 and M2 for collets
Via the 3 contact surfaces (support) on the measuring head the
force is transmitted to the measuring elements inside the housing.
It is recommended to use special collets with smooth finish in order
to avoid damage to these contact surfaces. Furthermore, care must
be taken to insert the measuring head in such a way that it does
not get tilted.
The „jaw centre“ inscription must correspond to the centre of
one of the three collet jaws. Please note, that compliance with the
above instructions will be decisive for the quality of the measuring
values.
The maximum load is mentioned on each measuring
head. Please make sure that this value will not exceed,
because this can lead to non valid measurements or
even to the destruction of the measuring head.
Measuring Head
Please be assured, that prior to measuring procedure
the measuring head is tight and plane-parallel clamped
to the rotational axis.

Operation with 3-jaw chuck:
If operated with 15 or 25mm extension, the 8mm extension
must always be mounted to the unused jaws (180°).
Always fit the extension symmetrically (0°, 120° and 180°).
Always mount the extension cylinder firmly (screw the Torx
screw down tightly).
Only with original accessories correct measured values
are ensured.
The measuring head extension cylinder transmits the tension forces
to a load cell located inside the measuring head. For different chuck
diameters Extension Cylinders are supplied which can be easily
exchanged to suit. A T15 Torx key is included for loosening and
tightening the screws.

Starting with the first measurement make shure that the measuring
head is fully charged. For this purpose the measuring head power
jack is to be linked to the charge receptacle of the measuring head.
From the safety point of view and to prevent
any injury, the loading bracket must be used
to put the measuring head M3 or M4 into the
chuck.
Mounting M3 und M4 measuring head
Take the loading bracket like shown in the picture and put the
measuring head M3 or M4 into it. After this, the measuring head
can be insert into the chuck until the loading bracket fit tighly in the
chuck. Now the chuck must be tensioned.
Because of that it is guaranteed, that the measuring head is not tilt
and it is in the optimum measuring position.
Put the measuring head like shown into the chuck.
Is the chuck tensioned, the loading bracket have to be removed.
Please be assured, that prior to measuring procedure
the measuring head is tight and plane-parallel clamped
to the rotational axis.

Maintenance/ Service
After the measuring head has been clamped in a parallel plane
the stand with the magnetic base must be fastened to the support
of the processing machine and positioned in such a way that the
lateral distance between the flattened end of the stand and the
measuring head is approximately 3 mm. The distance between the
top of the cover and the edge of the flattened part of the stand
should be 1-2 mm approximately. The stand should end with the
yellow cover of the measuring head before the steel part begins.
If no data are displayed although the handheld unit is switched on
and the measurement menu is activated, proceed according page
20 Trouble shooting.
The GFT-X is supplemented by the powerfull software module
ChuckExplorer. This program permits transfer of the data displayed
and stored on the Handheld Unit to a PC / laptop. A USB connecting
cable is included in the delivery package.
The gripping force and the corresponding number of revolutions
can be graphically represented, printed and stored on the PC.
It is also possible to convert the measuring data into an Excel
spreadsheet and to store the graphical representation as bitmap.
These data can then be used for further processing in any program.
This module represents an invaluable tool for documentation, in
particular with regard to a consistent quality management.
Measured data display/Storage on PC
When the handheld unit is switched on and rmp measuring is
activated, the current gripping force is determined and shown
on the display. When the chuck is rotating at the same time, the
display shows besides the gripping force the corresponding actual
number of revolutions.
Calibration, Recalibration
The GFT-X is carefully tested and calibrated on a test bench at
the factory. A calibration certifi cate is enclosed. This calibration
certificate documents the traceability to national standards, which
realize the units of measurement according to the International
System of Units (SI).
The zero point of the measuring head could change due to stress
(material fatigue) and due to temperature variation.
In a narrow range the measured value can be tared (set to zero)
refering page 8.
The GFT-X is a calibrated measuring equipment, a recalibration
should be performed by the manufacturer after 12 months
of operation. For calibration purpose we will ask you to send the
complete GFT-X unit back to your supplier.
Maintenance, Service
The GFT-X is a measuring device and should therefore be
treated very carefully.
Special care must be taken with respect to the measuring head
extension with its crowned surface. Due to the gripping forces, this
surface might be subject to wear and tear in the course of time. A
replacement is advisable at the latest when a ridge becomes visible
on the disk (spare part numbers see page 20.
If problems occur which cannot be solved as described on
page 21, the complete GFT-X must be returned to the supplier.
A detailed description of the problem will shorten the time
to repair and save costs.
To operate the ChuckExplorer there is no need of detailed computer
knowledge. The program could be installed and runs under
standard hardware.

For starting the measurement, the measurement tab must be active
and the Start button must be pressed. The button start changes to
Stop, number of revolutions and gripping force will be indicated.
Manual measuringMeasurement
There is a general distinction between two different methods for
storing the measured values with the GFT-X handheld unit and
directly with the ChuckExplorer.
Ifthemeasured value recordingis made directlybytheChuckExplorer,
then there is the possibility of a manual and automatic measured
value recording.
In case of manual storing of the measured values, the user can
decide by himself at what rpm value or at what force he wants
to store a value. When automatic storing is activated, two new
input lines are provided. Here the maximum number of revolutions
and the number of steps are defined, the program divides the
maximum number of revolutions by the number of the measured
values to be stored and logs them as soon as the relevant numbers
of revolutions are reached.
After clicking on the Information tab, you can enter further
parameters (jaw type, hydraulic pressure, etc.) in the righthand part
of the display window.
These parameters are recorded together with the measurement.
Measurement preparations
Relevant data and parameters can be entered into the program and
included into the measurement log so that a measurement can be
documented.
Machine or chuck ID and the name of the tester are entered on
the left side in the upper part of the program window. Up to 10
names are stored by the program and are available for future
measurements. They can be displayed and selected by clicking on
the button beside the text field.
The Date field is feeded directly from the system, however it can
be changed in the same way. This is necessary e.g. if measuring
sequences stored on the handheld unit are read out only after
several days.
By each click on the Store button, a measured value is stored and
displayed in the table on the left and in the diagram. The scale of
the chart is switched to the optimum range in order to get a better
optical presentation.
If a measuring sequence is complete, it can be stored on hard
disk Stop, File, Datei  Save. The ChuckExplorer suggest
automatically a filename, which consist of the collet-check box and
the date (e.g. Traub_07_09_10), however this line can be edited
individually. A printout on the printer is started via File Print.
Dependent on the printer and printer driver the diagram can vary.

Automatic measuring
If check box Automatic is activated , two new input fields are
displayed. Here you can enter the maximum number of revolutions
and the number of measurement steps. The software will then
determine automatically the equidistant numbers of revolutions
(rpm) for which the measured value is to be stored. The rpm
tolerance and the minimum time during which the rpm value must
be constant within the tolerance range can be set in menu item
Setup.

Display software
The measurement is started by the Start button. If the maximum
number of revolutions is reached, the program will automatically
terminate the measurement and display the corresponding table of
values and the graphical evaluation.
Download data from GFT-X handheld unit
Measurements recorded by a series of measurements and saved in
the internal memory of the GFT-X handheld unit, can be downloaded
directly from the handheld unit with GFT-X Download and
afterwards indicated. If several IDs and/or series of measurements
transferred so it is possible to switch forwards and backwards .
A backup of data of the indicated series of measurements is
necessary before. Chose therefore File Save... or Save all.
After download and the backup of data on the PC, data memory
of GFT-X handheld unit can be deleted completely with GFT-X 
Delete memory.
Loading and saving files
Choose File Save to save your recorded data. The directory
is user-defined, files end with *.gft. Will be several series of
measurements (Files) downloaded from GFT-X handheld unit, they
can be saved all at once with File Save.
Choose File Open to open an existing data file. The filename
appears in the Button bar.
Software update
The software of the GFT-X handheld unit is improved constantly and
is subject to certain changes. The actual software version will be
displayed in the welcome logo. An update is usually accomplished
