10mm thickness glass cutting test by green laser

--laser main configuration:

Green laser 355nm;

raylase 3d galvo system;

markingmate/MM3D control program;

--Test Conditions

1. The color of the glass sample is not good, and there are scratches on the surface. During cutting, the laser light will scatter on the scratches, and it will not be able to reach the lower surface through the glass, which will easily lead to chipping and cutting breakpoints.

2. The thickness of the glass is thick (10mm), and the dust generated by cutting is easy to accumulate in the cutting gap. It is necessary to increase the gap width, the spacing is 0.035, and the number of turns is >15

--Result:

1. The edge (corner edge) glass is frosted and opaque, and the laser will scatter when it hits it, so it cannot be cut.

2. The right-angled edge can be processed, but due to the thick glass (10mm), the dust generated by cutting is easy to accumulate in the cutting gap, so the gap width needs to be increased, the spacing is 0.035, and the number of turns is >15. (In the actual proofing, the chamfered edge is cut off to form a right-angled edge.)

*The glass sample received is not good in color and has scratches on the surface. In the actual cutting process, when the laser scans the scratches, it cannot pass through the glass to reach the lower surface, or scattering occurs, which reduces the power of the laser reaching the lower surface. As a result, under the same parameters, the front and rear cutting effects are inconsistent, resulting in edge collapse and cutting breakpoints.

--Cutting time: 65s
