The Spanish brand Turomas has offered equipment capable of removing a wide range of coatings during glass cutting. Glass suppliers have developed a wide range of products with high-performance coatings. This type of product needs to be protected from the moment of production and at all stages of processing, so they are coated with various plastics or protective resins that need to be removed during the glass cutting process. For this reason, Turomas has launched new developments.
The new auto-calibrated ACR or Advanced Coating Removal is capable of removing a wide range of coatings. These include various protective plastics and resins that need to be removed during glass cutting.
According to the company, the equipment is designed specifically to work with a plastic protective coating (TPF), as well as EASYPRO. This is a Saint-Gobain product that protects the glass from both mechanical damage and ageing during transport, storage and processing from application to tempering. EASYPRO simply evaporates during tempering, leaving no residue on the glass surface or in the furnace.
ACR contains two developments: a two-phase coating removal system and a cooling system. Both are patented by Turomas.
On TPF glass, the edges of the protective layer usually peel off and reveal the energy-efficient layer. Turomas has therefore developed a two-step coating removal system. First, the abrasive disc is positioned at a distance of 10 mm. It starts the removal in the opposite direction to prevent the protective layer from lifting. This prevents the edge from lifting easily in the second step. The speed for each type is predefined in the material library. Any type of coating can be removed in a single operation.
The cooling system prevents the abrasive disc temperature from rising too high at the edge. In addition to cooling the surface of the abrasive disc, the airflow cleans away any residue on the surface. This reduces the number of sanding operations required.
