Test Panel Scratcher CORROCUTTER 639
Purpose and application
The Test Panel Scratcher CORROCUTTER 639 is designed for the application of defined and reproducible scratches through coatings on test panels intended for subsequent corrosion tests. For this purpose the frequently used scratching tools in accordance with van Laar, with Clemen as well as with Sikkens are available.
The CORROCUTTER 639 prevents from the strain put to fingers and wrists of users when scratching by hand large series of test panels using a scratching stylus.
Design
The CORROCUTTER 639 is a desk-top unit. The slide is equipped with a linear guide (sliding bearing) and is moved by hand.
Procedure
Before starting the test the CORROCUTTER 639 should be positioned on a solid, flat base and levelled with the help of the supplied spirit level and the adjustable feet.
The test panel is placed onto the movable slide, with the coated side facing upwards, in that way that it sits close to the adjustable ledger underneath the rider weight which is located in position 0 (i. e. without exerting any pressure onto the scratching tool support) on the work arm.
The required test tool is then inserted into the scratching tool support at the end of the work arm and slightly fixed with the knurled screw.
To level the work arm the spirit level is placed onto the ball-bearing crosshead of the work arm while the scratching tool should touch the test panel. After levelling the scratching tool is tightened with the help of the supplied Allen key.
To place, position and remove the test panel in an easy and secure manner the work arm is lifted and arrested in the upheld position at the crosshead using the laterally located stop bolt. By sliding and fixing the rider weight on the work arm the required scratching force is adjusted (one division mark on the work arm = approx. 2 N). The force range comprises approx. 2 to 40 N. The adjustable ledger and the movable slide stop under the handle can be fixed by a knurled screw and serves as scratching length limiter.
While the left hand is holding the work arm with the scratching force adjusted, the right hand releases the stop bolt so that the scratch tip can be placed in a controlled manner onto the test panel to be scratched. The scratching procedure is executed by steadily drawing up the slide using the handle.
When moving the test panel laterally, it is possible to apply several parallel scratches exerting different scratching forces, so that the necessary setting for scratching through the coating can be determined.

101-0743.01.32 St. Andrew's cross template 60°/120°
When using the cross scratch template it is possible to apply also scratches in the shape of a diagonal, rectangular cross with variable scratch lengths. For this purpose the cross scratch template is positioned against the adjustable ledger of the CORROCUTTER 639. The test panel to be scratched is placed into the jog of the cross scratch template and scratched by executing the usual procedure.
Then the scratching procedure is repeated on the test panel having been rotated through 90° and thus the required cross scratch is completed. The maximum dimensions of the test panel are 270 x 270 mm.
The St. Andrews's cross template enables the application of scratches producing a St. Andrew's cross either in a horizontal or in a vertical position. For this purpose the template has to be turned round (upside down) after the first scratch. Then the test panel has to be positioned after having been rotated through 90° and the second scratch is carried out.
Decisive for the vertical or horizontal position of the St. Andrew's cross that will be produced, is the marked edge of the ledger of the template jog against which the lower edge of the test panel is positioned for the first scratch. The two edges of the ledger are marked - one by "s" for upright position and the other by "l" for horizontal position. The maximum dimensions of the test panel are 210 x 297 mm.

The SledCutter 295 XVII elevates manual cross hatch cutting to a new level.
With adjustable cutting force and linear guidance, it enables the application of uniform, standardized cross-cut patterns on coated test panels – precise, fatigue-free, and safe.
Three different cutting tools (6x1 mm, 6x2 mm, or 6x3 mm) provide maximum flexibility for your testing needs.
The Multi-Cut Adapter enhances the functionality of our Corocutter 639, enabling precise, right-angled cross-cut patterns with adjustable cutting forces from 2 to 40 N. This guarantees consistently accurate cuts, revealing the substrate clearly.
Both devices contribute to making your testing processes more efficient and accurate

Purpose and application:
For standard-conform corrosion testing, the application of an accordingly conform defined cut “scribe“ line is inevitable.
This “scribe“ line is commonly applied by a huge part of users in a manually handled manner.
