This machine is located in the chemistry lab which measures the strength of painting adhesion.

The device includes a cutting knife, magnifying glass,a special kind of glue, and brush to clean polymer.

 The following description shows how the device works :

 

First, by using a cutting knife , we create some intersection cut on the surface of the colored cylinder. 
Then we clean the cut surface by using a special brush.

After that we cover the intersection part by a sepcial glue.

Next we remove the glue having a high speed and angle of 180 degrees.

Finally we look at the crossed lines carefully and compare them in order to find out if there is any defects.
