Page 19 DIAMOND TOOLS Glass industry - Issued November 2020 by KGS DIAMOND Tech Tips To achieve maximum performance and optimal lifetime, it is recommend to pay attention to the following parameters in line with the machine instructions and operating conditions: Coolant Use clean water and additives without solvents. Keep constant flow at point of grind. Pressure Apply the right pressure for the belt settings, too low can cause glazing, too high leads to uneven wear of the belt. About 20mm deflection under tension. Timing The grinding surface of the belt should touch the glass once the pane arrives to the middle of the belt. Aim at the middle of the belt for minimum firing and longest belt life, and less unnecessary wear. Pulleys Use clean pulleys with even surface to ensure a smooth running belt. Depending on configuration, normal belt crowning or slight bevel on the outer edge. Maintenance Check regularly the set parameters of the machine, this avoids unnecessary belt wear. Seaming width Note: Doubling the seam width from 0.5 mm to 1.0 mm means 4 times the stock to be removed. 0.5 mm 1.0 mm 2 1 4 3 4.0 mm 0.5 mm = 100% of life 1.0 mm = 25% of life
