Page 3: Introduction
BAQ kaloMAX Manual 1 Introduction The kaloMAX is a spherical cap grinder for the determination of the layer thickness of coatings and layer systems. A steel ball lies on a revolving shaft and also on the angular positioned sample. A small spherical cap is ground through the layer on the sample into the base material by means of the ball and a little abrasive slurry. -
Page 4: Installation
Manual 2 Installation The kaloMAX has to be located in a place, where no vibrations or agitations can occur during the measurement. The current supply is done by a wide range power supply with an input voltage range of 85 to 264 V and a frequency of 47 to 63 Hz. -

BAQ kaloMAX Manual 3 General handling Power switch / fuses The power switch and the fuses ( 2 x T 1 A ) are located at the back side of the unit between power connector and power switch. Specimen holder The samples are clamped into a small vice. - Page 6 BAQ kaloMAX Manual Option removable specimen holder The vice holding the sample can be removed from the compound table. With a microscope it can be checked, if grounding is complete and the base material is visible. If the grinding process shall be continued, the vice can be replaced to the compound table.

Page 7: Programming
BAQ kaloMAX Manual 4 Programming kaloMAX provides the facility to save frequently used combinations of revolutions and grinding period. The combinations are identified by a program number and can be quickly recalled when required. After power up, the last program is active. By means of the ↑↓ buttons beneath the readout for the program number, the desired program can be selected. -
Page 8: Doing A Measurement
BAQ kaloMAX Manual 5 Doing a measurement The result of the grinding process depends on the following factors: • grinding paste • number of revolutions • grinding period • diameter of the ball • normal force exerted by the ball The weight of the ball will be taken up by the shaft and the sample. -
