nivelSWISS

Precision hand tool for the alignment of machine tools

nivelSWISS is a precise electronic inclination measuring instrument with an analog display on a galvanometer. One of its key mechanical features is its excellent zero-point stability. The nivelSWISS is therefore well suited when adjusting machine tools. 

 

Depending on the application, nivelSWISS is available either with a horizontal base or with an angular base. The measuring surfaces are scraped to ensure the high precision of the instrument. 


Calibration Certificate

 

The nivelSWISS can be delivered with an internationally recognised Calibration Certificate against a surcharge

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. 

 

CALIBRATION OF SURFACE PLATES (FLATNESS)

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 THE ABSOLUTE POSITION OF A Guideway

Subject:

The straightness of a guide way can be measured very easily and very precisely with the software wylerSPEC. Since the straightness is independent of the absolute position of the guide way in space, it is enough to measure “relative”. On the other hand, when adjusting a machine, it can be very helpful to know the exact position of the guide way in space.

 

Measuring task:

For a guide way, not only its straightness but also its deviation from the horizontal plane shall be measured. Furthermore, it should be shown where and how much the guideway should be corrected to adjust it horizontally.

FLATNESS MEASUREMENT ON A CIRCULAR SUPPORT OF A TURN TABLE

Subject:

Module 4 of the software wylerSPEC allows users to determine the flatness of a rectangular surface very easily. The measurement of the flatness of a circular support though, as it is used for large machine tools, is much more complex. 

 

Measuring task:

The flatness of a circular support with a diameter of 2.3m must be determined.

MEASUREMENT OF A CIRCLE ON A ROUND TABLE OF 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:

The flatness of a rotating table of a grinding machine with a diameter of 3200 mm must be measured. Thereby only the flatness of a circle must be measured and not the whole table.

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.
