[0002] Acrylic glass for car windows (also known as plexiglass or acrylic glass) is a material widely used in the automotive industry. Acrylic glass for car windows has broad application prospects in the automotive industry due to its light weight, high light transmittance, impact resistance and good processing performance.

[0003] In the process of automobile manufacturing and maintenance, the grinding of the edges and corners of the car window acrylic glass is a very important process.
