PAINTXPLORER 548
Technical description
Description
The PAINTXPLORER 548 has been developed to extend the range of the application of the PAINT BORER 518 MC/518 USB, especially targeting sensitive drillings, particularly into rigid/brittle materials. It is possible that, already at minor eccentric irregular running of the drill used or of its centre axle, such materials can be subject to breaking off of the cutting edges including chipping off, leading afterwards during the optical measurement with the microscope also to limitedly definable transitions between the layers to be measured.
To minimise these limitations the PAINTXPLORER 548, a convenient tabletop unit, is equipped with an improved rotating/sliding high precision axle-bearing device. Although the application can be considered as mobile in the range of the length of the mains cable, it is nevertheless the question of a laboratory equipment. It can either be held in hand or used in connection with the measuring stand that is included in the scope of supply.
The appropriate measuring microscope is not integrated in the housing, as for the PAINT BORER 518 MC/518 USB, but is available separately, if required, as a self-contained component (e. g. for the evaluation of damages of lacquers, corrosion creep, pores etc.) which results in the slender handy design of the PAINTXPLORER 548.
Operation
In principle, the PAINTXPLORER 548 is used in the same way as the PAINT BORER 518 MC/518 USB:
- Application of a contrast mark.
- Placing the instrument onto the specimen, positioning the drill directly above the test point. When using the stand, position the test point on the specimen directly beneath the drill. Then fix the specimen from underneath by rotating the pressure plate.
- Drilling through the layer to the substrate.
- Carrying out the measurement with the help of the microscope considering the scale factor.
The geometry of the specimen admissible for the coating thickness measurement with the PAINTXPLORER 548 depends on whether the drilling unit is used with or without drilling stand.
