Precision is important when measuring glass
Hello, I’m Andrei, Glas Expert’s Construction Engineering Advisor.
My job involves Construction surveying at the various sites where we have ongoing projects and then designing the finished products, which we fully realise in the Glas Expert production halls.
My duties also include troubleshooting installations and finding optimal solutions for execution, commissioning and exploitation by the final consumer of the glass products we made. These solutions are discussed and established together with the designers and architects, or directly with the project beneficiary.
For uncompromised accuracy on building surveys, in addition to using traditional measuring tools, such as the classic ruler, the telescopic ruler, the electronic range finder, the electronic inclinometer (for angle measurement) and the laser (for better measurement accuracy), Glas Expert also acquired a Proliner 3D digital scanner in 2016. This scanner significanly shortens the time spent at the construction site marking out, taking measurments, as well as the time it takes to design the glass installations.
The Proliner 3D scanner is very easy to handle and intuitive to use, and the incorporated touch screen allows me to quickly identify and rectify any mistakes (human mistakes) made in the use of this state-of-the-art measuring instrument.
With a measuring accuracy of ± 0.3 mm, the scanner can detect any deviations from flatness and verticality; deviations that occur frequently on building sites. As far as design is concerned, all site measurements are saved in the device in ‘.dxf files‘, a supremely useful format, and all drawings can be edited easily in AutoCAD. The .dxf files can be read by our glass processing machines and can include numerical coordinates for CNC machine cutting, or for printing on the ceramic enamel printer.
In conclusion, the Proliner scanner is invaluable in my everyday work, to eliminate any potential mistakes that can be made when a survey is conducted using instrumentation ‘traditional’ tools; in taking physical measurements, in the transcription of the physical measurements, and ultimately in the design of the final product using AutoCAD.
Possibly the first time you’ve heard of it, or perhaps a printer comes to mind but you’re probably thinking about something to do with advertising, right? Well, Indeed, there is something called a UV printer, that can print on glass and is used in the advertising industry but that’s not it !
Sometimes tempered glass breaks without an obvious cause. When this happens breakage could be caused by; the glass being impacted in the same place over time (breakage can occur then or at a later time due to accumulation of tension in a particular area), pressure points in places where there are metal fittings (such as the screws in the profiles), the continuous tensioning of the glass (defective assembly, when the glass is tightened – when the fixing points are not coplanar), when the glass is too tight in the frame, if the glass edge is not finely finishing, shaving remains on the edges of the glass or if nickel sulphate inclusions are left in the float glass.
