Sapphire can be used as a sapphire window, and the upper mirror of a mobile phone is also called a window. The sapphire phone mirror is made of sapphire. Sapphire is scratch resistant and wear-resistant, and the same principle is used to make phone mirrors. Although it is a wear-resistant material, it cannot withstand strong impacts and collisions.

The sapphire used to make window panels is not natural sapphire, and the sapphire material used for phone and watch mirrors is artificially manufactured. Being artificially manufactured does not mean that its performance is poor. Its texture is hard, there is no difference in function, and it is not easily scratched by strong substances. But caution is still needed when using the product, even if the sapphire phone mirror is hard, it still requires careful care.

Sapphire glass is only wear-resistant, and hard things are often brittle, so it can also burst under severe collisions, which is also the reason why sapphire phone screens are prone to cracking. Secondly, when sharp objects scratch the surface of glass, it is also easy to cause scratches. This depends on the strength and speed of the scraping. The smaller the force area, the sharper the contact point, and the faster and stronger the speed and force, the easier it is to be scratched. Another issue is the force angle of glass, which can easily cause significant scratches at around 45 degrees. Unlike other materials, sapphire cannot remove scratches through grinding or polishing and can only be replaced with a new one.

Sapphire mobile phone mirror is a thin plate part with high precision requirements, which can be processed by multi wire cutting method. Multi line cutting is a new cutting method that utilizes the high-speed reciprocating motion of metal wires to bring abrasives into the workpiece processing area for grinding, cutting hard and brittle materials into hundreds of thin sheets at once. Due to the wire contact between the metal wire and the workpiece during cutting, there is high resistance and low efficiency.
