Coated glass has become an integral part of the construction industry. Whether as a thermal insulation or sun protection layer, the functions of glass coatings are diverse. They reduce the emissivity of infrared radiation, ensure electrical conductivity, can change the refraction and translucency of light and create decorative effects. Mirroring and anti-reflective glass surfaces are also created with coatings. systron customers such as AGC Interpane Plattling, arcon Flach- und Sicherheitglas in Feuchtwangen or vandaglas Eckelt in Steyr, which specialize in the production of architectural glass, continue to set new standards in the coating of architectural glass.

systron’s Quality Management is also continuously working on optimizations and was recently able to focus on edge deletion and tested this feature very successfully. Such edge removal is not carried out with the standard proHD glass processing centre. There are new options for this machine, such as the second water cushion as a counter-holder, an additional force measuring system, and some software adaptations.

For successful edge removal, the axial force must be adjustable and constant. This is necessary because the wear of the tool should be automatically adjusted to ensure that the same process force always prevails. We achieve this with our patented water cushion in conjunction with the real-time force measurement system. A constant contact pressure is set, so the tool always presses against the glass with the pre-set 50N. This is a standard function of systron systems in radial machining. Originally it was developed for consistent polishing of glass edges, now it can also be used axially to remove coatings.

By using a second water cushion as a counter-holder, the glass pane is clamped between the two cushions without mechanical contact during processing and held perfectly in position. The rear water cushion prevents the glass pane from bending. This means that edge deltion can be carried out not only on the outside of cutouts of any size and shape, but also on the ends of the glass.

When producing insulating glass, edge deletion should be carried out in the contact area with the sealants in order to:

• ensure secure adhesion of the insulating glass sealant to the glass.
• avoid damage to the layer on the edge of the pane due to the pumping movement of the insulating glass pane.
• prevent moisture from infiltrating the individual layers.
• not causing corrosion of the silver layer through reaction with air and water.

Mitre grinding is also possible with the latest proHD version. The mitre edge is created by specially grinding an edge at 45°.

Mitre grinding is a special type of edge processing and is typically created with an angle of 45°. This allows you to connect glasses that are not at right angles (90°) to each other. Mitres are used in glass processing, for example, to precisely and beautifully design corners and edges of glass structures such as showcases, shelves, or frames. The mitre allows two pieces of glass to be connected seamlessly and with clean lines, creating an attractive overall appearance.
