Yes, a glass cutting machine can cut tempered glass, but it is not recommended to do so as it can be very dangerous and result in shattered or cracked glass.

Tempered glass, also known as safety glass, is made by heating regular glass to a high temperature and then rapidly cooling it. This process creates a stronger and more durable glass that is less likely to break or shatter. However, once tempered glass is cut, it loses its strength and safety properties and can easily break or shatter upon impact.

Cutting tempered glass requires specialized equipment and techniques to ensure that the glass is not damaged or compromised in any way. For this reason, it is recommended that only trained professionals with the proper equipment and experience handle tempered glass cutting.

In conclusion, while a glass cutting machine may technically be able to cut tempered glass, it is not recommended and should only be done by trained professionals using specialized equipment and techniques.Generally, the glass is tempered after cutting.
