Glass surface marks trace line, and then glass is fractureed with the method for machinery again.This method is although relatively easy, but with machine
During tool method fractures glass, the edge of glass is unsmooth, and due to glass edge residual stress and fine crack
The intensity of glass can be reduced.So at the edge also needed to using the method glass-cutting after cutting cleaned, polishes and be hot
The subsequent handlings such as reason.2nd, the laser cutting technique of glass has many superiority compared with traditional cutting technique.Laser is cut
The glass edge that cuts out is smooth, without horizontal fine fisssure, without fragment.Avoid and occur scratching on sheet material and by glass breaking

CO2Laser is easily all absorbed in glass surface.Therefore, CO is utilized2During laser glass-cutting, crackle extends since surface,
Kerf quality is poor, the finite thickness of glass-cutting, and can not cut compound glass, and the bad control of crackle, is mainly used to during cutting
Cutting straight line type glass material.And wavelength is 1 μm or so of YAG laser-light transparent glass, absorption of the glass to laser energy is
Body absorpting form, the cracking of glass is uniform penetrating, and the YAG laser glass-cutting method absorbed based on body not only can obtain
More preferable cut quality, but also cleavable compound glass, laminated glass and glass tube, its greatest drawback is inefficiency, by
