Everyone knows that most glass shapes are rectangular; An important characteristic of rectangles is that their diagonals are equal. In actual production, there may be a certain degree of deviation between the processed product shape and the ideal shape, manifested as the diagonal side being long and the other side being short. Therefore, the appearance shape will not be a standard rectangular shape, which may be trapezoidal or parallelogram

So the diagonal measurement of glass products processed by glass edge grinding machines is also one of the more practical and fast product quality testing methods. But even if the diagonals are equal, it is not necessarily a standard rectangle. Don't forget that isosceles trapezoids are also diagonally equal, and it is necessary to measure the long side of the balance edge to accurately determine whether it is a standard rectangle

Control of diagonal error generated by linear glass edge grinding machine:

1. The glass transportation movement is balanced, if the glass grinding wheel periodically moves back and forth. This way, the product processed by the glass grinding machine will be uneven and have wavy edges

2. The control glass grinding wheel has no forward or backward movement, and the product has a corresponding movement with the knife in the longitudinal direction. There are three possibilities:

(1) During the processing of glass edge grinding machine, due to uneven cutting forces between the two opposite edges. However, the clamping force is not large enough, causing the product to move longitudinally, resulting in non parallelism of the glass wave edges and opposite edges during glass edge grinding machine processing
(2) The uneven movement speed on both sides of the product leads to non parallel edges, resulting in large and small ends
(3) There is a large gap between the adjusting screw of the main beam and the adjusting gong, when the centering mechanism is aligned. Squeezed by centering force. The distance between the two beams increases, resulting in non parallelism of the wave edge and the opposite edge
