MACHINE TOOLS / CHECKING OF ROTATION ERRORS
Subject:

All machine tool manufacturers highly value rotation measurements since they allow a reliable judgement of the quality of a machine tool with little effort.

Measuring task:

Pitch and roll values on a machine must be determined. The measurement should be done reliably and efficiently.

MACHINE TOOLS / CALIBRATION OF SURFACE PLATES, STRAIGHT EDGES AND SQUARES
Subject:

The quality of granite references like surface plates, straight edges or squares must be checked and certified regularly.

Measuring task:

The measurement and calibration of granite master squares and surface plates should be performed efficiently. 

MEASUREMENT OF PITCH AND ROLL ON A GRINDING MACHINE
Subject:

A manufacturer of large metal plates has several large surface grinding machines in his workshop. The geometry of these machines must be checked and documented periodically, and, where required, to be corrected.

Measuring task:

On a large surface grinding machine with guide ways with a length of 18m pitch and roll must be checked. The maximum tolerance is 0.1 mm/m.

MACHINE TOOLS / MACHINE TOOLS / POSITIONING OF A CUTTING HEAD
Measuring task:

The position of a cutting head or the table must be checked and adjusted if necessary.

MEASUREMENT OF THE RECTANGULARITY OF THE HEAD OF A ROUND TABLE GRINDING MACHINE
Subject:

A manufacturer of large metal plates has several large surface grinding machines in his workshop. The geometry of these machines must be checked and documented periodically, and, where required, to be corrected.

Measuring task:

The rectangularity of the axis of a grinding head of large grinding machine in relation to the bearing of a round table with a diameter of 3200 mm must be measured. Based on the results, if necessary, the inclination of the head must be adjusted.

SCREW PUMP / ADJUSTMENT OF GRINDING ANGLE
Subject:

The performance and efficiency of a screw pump is strongly depending on the precision of the 2 screws.

Measuring task:

Precise adjustment of the grinding angle during production of the screws. This task is impeded by the fact, that during adjustment the display of the instrument cannot be seen. 

MACHINE TOOLS / CHECKING OF ROTATION ERRORS

Subject:

Machine tools must be checked periodically for geometrical deviations, since changes of the geometry have a direct influence on the quality of the parts manufactured on that machine. 

It is very important that during the displacement in one axis the tool will follow a straight path compared to the table. On machines of light-weight construction the table can show a deformation due to its own weight. 

If the complete machine construction is tilting during the displacement of the table this is a sign for insufficient stability of the foundation or for a flexibility of the stand (damping elements).

Measuring task:

The geometry of a machine tool must be verified. The check must show rotational errors of the table during displacement. The measurement should be made reliably and efficiently. 

MECHANICAL ENGINEERING / INCLINATION OF A HUGE BEARING RING
Measuring task / Goal:

Checking the inclination at various positions of a huge bearing ring. 

EFFICIENT CHECKING OF THE ALIGNMENT OF A MACHINE / CASE 1 + 2
Subject: 

Customers often have the need to verify whether a machine is still in tolerance after e.g. a crash or during the yearly maintenance on the machine. 

Calling in an external technician might be too cumbersome, too time consuming or too costly. 

Measuring task: 

Efficient checking of the machine. 

MECHANICAL ENGINEERING / MACHINE TOOLS / ADJUSTMENT ANGLE OF A TOOL
Measuring task / Goal:

Checking the adjustment angle of a tool on a large rotating lathe.
