Production Of Glass Discs
What Are The Glass Discs For?
In general, it can be said that in all circular viewing holes where the use of plastic is inappropriate. In practice, we encounter glass wheels, for example, with oil marks, pumps, optical filters and various sight glasses.
Technology Of Glass Discs Production
When the glass breaks, it happens at the weakest point. This is used when dividing glass. At the point of cutting, the glass is scratched on the surface and breaks at that point. In this way, any shape and wheel can be broken out of the glass. Unfortunately, this method of production creates cracks, which makes the glass more fragile. Larger diameters are mainly produced by this method. The smaller the diameter, the more difficult it is to break out.

We round the glass, or gradually grind it, until it is perfectly round. Grinding can achieve accuracy in hundreds of millimeters. The edges have a clean break, thanks to which the glass wheels achieve higher mechanical and thermal resistance.
Advantages Of Glass Discs
Hardness
Plexiglas or other types of plastic are too soft, easily scratched and turn gray over time or become dull. Glass, on the other hand, has a high surface hardness and does not scratch as easily as plastic.
Precision
We grind glass wheels with tolerances of up to hundreds of millimeters and perfect roundness. Accuracy is especially valued in optical systems. For common applications, tolerances in the order of tenths will suffice.
Heat resistance
Although the melting point of glass is around 1000 ° C, glass is prone to rapid temperature changes or temperature shocks. Thanks to chamfered edges and chemical hardening, we are able to achieve interesting results.
Price
The original grinding technology and more than 10 years of experience contribute to a very interesting final price, especially in the serial production of a large number of pieces.
