“The operating hours our former seamer integrated in the Lasiluoto insulating glass line came to a full end after a service life of 12 years. Annual maintenance costs became too high and there were too many production interruptions due to failures,” comments Kari Lilja, president and CEO of Lasiluoto.
In addition, the industry has tightened the requirements for edge grinding of glasses, especially for large glasses, rough edge (pencil edge) grinding is required instead of seaming. “It is important for us to keep our quality level high and serve our customers according to their needs, so the decision to purchase a new vertical grinding machine was easy to make,” Lilja says.
The systron vertical grinding machine technology is the best in its field, Kari Lilja was convinced after seeing the machine for the first time during a customer visit to Interpane in Germany in 2018. A representative of Interpane praised the machine as very reliable and superior in serviceability. In addition, glass support and tool cooling with a water bed ensure top quality and capacity without scratching soft coatings.
“Our systron es1 6033 seaming machine has four tools with one tool spindle, which cover almost the entire edge grinding/seaming of our insulating glass production. Glass thicknesses from 4 to 12 mm are ground or seamed according to the customer’s specifications with tools supplied by systronTOOLS.
The tool is changed automatically according to the glass thickness, so there are practically no production interruptions due to the tool change,” says Sami Kuivalainen, Lasiluoto’s production manager.
Operators duty is just to select the grinding method from the machine’s control panel and load the glasses on the line.
