Why the glass should be fine grinding before tempered by glass tempering furnace?

1. if the glass no edge grinding or no fine grinding, during the heating and cooling process, defects at the edges of glass can easily lead to the risk of "furnace explosion" due to excessive or uneven stress concentration, which can cause significant damage to the glass tempering furnace.

2. If the glass is not edged or only roughly edged before entering the furnace, there will be small slag particles at the edges of the glass. When the glass is driven or swung inside glass tempering furnace. these small slag particles will fall onto the conveyor rollers. Especially when these slag particles fall onto the ceramic rollers in the heating furnace, under high temperature conditions, after being crushed by glass, the slag particles will stick to the ceramic rollers, this causing serious marks on the glass. After this situation occurs, you should immediately stop the machine and clean the ceramic rollers. If the furnace is frequently shut down, it will result in significant production costs and also make the service life of glass tempering furnace shorter.

3. In the meantime, for the excavation and drilling of irregular glass, it is also necessary to grind or chamfer the processing parts to ensure that there are no burst edges or cracks present.
