MACHINE TOOLS / ROTATION CHECKS
Measuring task / Goal:
A machine tool must be checked on possible geometrical deviations. The check must show up eventual rotations of the table during displacement. The measurement of geometry should be made in a quick, reliable and simple procedure ant thus with a good cost-benefit effect.

MEASURING - CALIBRATION / FLATNESS MEASUREMENT, ANGLES
Measuring task / Goal:
The calibration of granite master squares should be performed as easily and efficiently as possible. The equipment used should offer a good cost-benefit relationship and requirements regarding the qualification of staff should be as moderate as possible, enabling workshop staff to easily make use of the system.
MECHANICAL ENGINEERING
Measuring task / Goal:
With simple means the position of a cutting head can easily be checked and adjusted if necessary.
Alternatively to the new adjustment of the tool the table can be inclined and checked.
MECHANICAL ENGINEERING
Measuring task / Goal:
A huge bearing ring is being measured in the frame of the quality assurance scheme on several points in respect of the actual inclination.
MECHANICAL ENGINEERING
Measuring task / Goal:
Check of the adjustment angle of the tool on a large rotating lathe.
MACHINE TOOLS / SPINDLE ALIGNMENT
Measuring task / Goal:
The deviation from the right angle between the two working positions „horizontal“ and „vertical“ must be determined.
This measurement is required during the assembly, the error correction by scraping when the unit is mounted on a temporary frame with doubtful stiffness as well as during the final inspection of the ready mounted machine tool.
The measuring uncertainty must not exceed two seconds of arc. Calculations involved must be possible without the aid of a computer.
MEASUREMENT OF THE ABSOLUTE POSITION OF A GUIDEWAY
Measuring task / Goal:
For a guideway not only its straightness but also its deviation from the horizontal plane shall be measured. Furthermore it should be determined where and how much should be corrected to adjust the guideway horizontally.
FLATNESS MEASUREMENT ON A CIRCULAR SUPPORT OF A TURN TABLE
Measuring task / Goal:
The flatness of a circular support with 2.3m diameter has to be measured.
ALIGNMENT OF AN INJECTION MOLDING MACHINE WITH WIRELESS INCLINATION SENSORS
Measuring task / Goal:
The customer is searching for a more efficient solution for this process during in-house commissioning as well as for the commissioning at the customers premises. If possible the adjustment should be done by one single technician. To assure that no instrument is accidentally pulled down, a wireless solution is to be favoured.
POSITIONING OF A HEAVY PART WITH AN OVERHEAD CRANE
Measuring task / Goal:
In order to achieve the required accuracy the bending of the building respectively of the overhead crane should be measured. With the resulting values the vertical correction of the crane should be calculated .
MACHINE TOOLS / ANGULAR POSITIONING ERROR OF A- AND C-AXIS
Measuring task / Goal:
Measure deviation from anticipated angle on different angular positions. As the centre of the axis of rotation is often not accessible, an additional challenge is added to the task. In many cases the measured values are entered in the CNC controller for corrective action. In order to include errors due to mass of the machine components, the measurement should therefore be collected near by the cutting position. Uncertainty of measurement should not be greater than 1 to max. 2 Arcsec.
VERTICAL ALIGNMENT OF MEASURING PROBES ON A STRAIGHTENING MACHINE
Measuring task / Goal:
All 3 probes have to be in an absolute vertical position. The acceptable tolerance for this measuring task is ±0.04 mm/m. In order to achieve this, the probes have to be adjusted vertically in both axis.
Note: this adjustment is only required after an exchange of the probes.
LARGE GRINDING MACHINE WITH FLAT GUIDEWAYS
Measuring task / Goal:
On a surface grinding machine with 18-meter-long guideways set 1.3m apart, the co-parallelism of the two guideways has to be checked periodically. The guideways have to be within a plane with a maximum tolerance (error) of less than 0.1 mm. The complete machine and its guideways can be adjusted by means of supporting screws placed at 750 mm intervals.
MEASUREMENT OF A CIRCLE ON A ROUND TABLE OF A GRINDING MACHINE
Measuring task / Goal:
The flatness of a rotating table of a grinding machine with a diameter of
3200 mm has to be measured. Thereby only the flatness of a circle has to be measured and not the whole table.
MEASUREMENT OF PITCH AND ROLL ON A GRINDING MACHINE
Measuring task / Goal:
On a large surface grinding machine with guide ways with a length of 18m and a distance of 1.3 m pitch and roll have to be checked regularly. The maximum tolerance is 0.1 mm/m.
MEASUREMENT OF THE RECTANGULARITY OF THE HEAD OF A ROUND TABLE GRINDING MACHINE
Measuring task / Goal:
The rectangularity of the axis of a grinding head of large grinding machine in relation to the support of a round table with a diameter of 3200 mm has to be measured. Based on the results the inclination of the head has to be adjusted.
ALIGNMENT OF THE HOLES OF FLANGES
Measuring task / Goal:
Before starting the welding process, the holes of the flanges have to be aligned (twisted) in such a way that the holes have less than ±15 Arcsec deviation from each other after the welding process.
PITCH AND ROLL MEASUREMENT WITH 2D-ZEROTRONIC MEASURING UNIT AND MT-SOFT-SOFTWARE
Measuring task / Goal:
The machine should be very accurately levelled in X- and Y-direction. Afterwards a pitch and roll measuring report with numerical and graphical information is required.
MEASUREMENT AND CERTIFICATION OF THE TORQUE-RESISTANCE ON AN ENGINE-SHAFT
Measuring task / Goal:
The torsion of an engine-axis mounted on a testing-rig with a base of 12m x 12m has to be measured precisely and put in relation to the applied torque.
