DIM is a measuring and inspection system for wire drawing dies with manual focusing and measuring functions based on image processing. The manual focusing enables a very price competitive setup. Nevertheless the DIM provides a high measuring accuracy by image processing.
Standard measuring functions are:
-inside diameter of drawing dies;
-roundness of inside cylinder of drawing dies.

DIM is a measuring system for diameter and roundness of wire drawing dies.

DIM with 3 measuring objectives and eyepiece

The measurement is performed optically by image processing software.





Because of the manual focusing the DIM is a very price competitive solution, but provides a high measuring accuracy too!


Additionally, the DIM provides the option of the visual inspection of the drawing die by eyepiece.


The DIM is equipped by default with 3 measuring optics, which covers a diameter measuring range from 0,1mm to 5mm.


The software provides special functions to determine the exact focus position. In connection with the Software, following measuring accuracies can be achieved:



Drawing Die Diameter Measuring accuracy

‹0,4mm ±3 µm

0,4…2,4mm ±5 µm

2,4…5,0mm ±10 µm


The software offers the following functions:

-Live video representation of the camera image on the PC screen

-automatic measurement of diameter and roundness of the drawing die


In the simplest case the DIM is equipped only with 1 measuring objective and has no visual eyepiece.
