The Measuring Principle

The PAINT BORER 518 USB operates in accordance with the standardised wedge cut method in which the specimen is cut in a defined angle.

With a high-resolution digital microscope (50 X magnification) with integrated light (8x white LED, adjustable), equipped with a 2 million pixels CMOS image sensor and scalable precision measurement, a direct image capture directly from the object is made.

With the new 518 USB, connectable to a PC, laptop/WINDOWS-tablet, a convenient digitally supported way is given for visual recognition/ detection/measurement and documentation.

An appropriate software is included.

The Measuring Instrument

The PAINT BORER 518 USB is a very compact Instrument. All the principal components - the drilling device, the digital microscope, the specimen illumination and the battery - are enclosed in a sturdy housing.

A slide moving on horizontal slide-ways houses the drill and microscope and gives the PAINT BORER 518 USB its particular feature: the instrument itself does not have to be moved for measuring after drilling.

The drill is spring mounted in the slide so that it can be pressed down onto the specimen with minimum force, the drill being switched on automatically when this is done. The carbide drills are easy to exchange and supplied with different accurately maintained cutting angles for 3 standard measuring ranges.

The light button on the backside of the PAINT BORER 518 USB can be set for either continuous light as well as three levels of illumination or interrupted illumination to prolong battery life. A 9-volt rechargeable battery is employed; mains operation with the charging unit is possible.

Optionally, a specimen table for fixation/ measurement of small parts is available (details see page 6).

Depending on the drilling angle, by a tangential function the selected intervals can now be assigned due to the respective layer thickness of the obliquely vertically cut areas.

Thus, with only one bore, every single layer as well as individual layers of multi layers can be captured and measured.

The necessary formula works and all the relevant controls are already part of the standard software.

Also ellipsoid holes on one-dimensionally curved geometries are already considered in a reasonably feasible manner.

For improvement of the contrast within the visual determination/recognition of the layer transition lines, the display of the hole is by choice in black & white as well as also in a selection of other different colors possible (see examples).

As an additional great advantage to avoid communication-given information errors from user to user, customer to supplier, supplier to customer, etc., there’s the possibility of storing/logging the entire relevant measuring thread with data and image.

The Operation

The coating thickness measurement with PAINT BORER 518 USB is very simple: Apply a contrast mark (felt tip pen) and place the measuring Instrument on the specimen. Move the drill into position over the test point and lower it causing the motor to switch on. Drill the coating through to the substrate. Move the microscope over the hole and switch the lamp on.

The image Is shown on the display of the connected PC / Laptop / WINDOWS-Tabiet and can be saved for further use/measurement/documentation.

The contrast for the comfortable present imaging sharpness is already preset accordingly.

Use the mouse for the cursor to mark the appropriate relevant positions - the center of the drilled hole as well as all visible layer transition lines.

Examples:

ISO 19399, ISO 2808, ASTM D4138, ASTM D 5796

Specimen platform for fixation/measurement of small parts consisting of: Base stand, counter plate with drill window, inflatable rubber impression ball with ergonomic Peleus ball and 3 flexible hard foam cushions.

The small specimen to be measured is fixed after manual positioning on the flexible hard foam cushion under the drill window of the counter plate.

Minimum sample size for small parts: à 17 mm (whether round, square

or otherwise shaped; has to be considered in relation to the drilling and measuring opening of the specimen table I)

The circular executed drilling and measuring opening of the counter plate has a diameter of 15 mm.

Its edge holds the flat surface of the small specimen to be measured, pressed from below, at the correct height level for drilling as well as for focusing and measuring by the measuring microscope.

The upper counter plate with drill window can also be used separately as a free positioning aid (just loosen 4 screws) to set up the PAINT BORER 518 MC or 518 USB on surfaces that would otherwise not be comfortable to set up resp. use due to their too small dimensions (drilling & measuring).
