Glass has widespread practical, technological, and decorative use in, for example, window panes, tableware, and optics. The flat glass It is one of the most used materials in the construction and architecture industry, due to its properties and the large number of options it offers. It is also used in the automotive industry in windshields, mirrors, windows, sunroofs, etc. In the production of cabinet doors, table coverings, furniture and other decorative elements. Optical industry, photovoltaic and electronic sector, etc. Due to the properties and characteristics of flat glass and thanks to technological advances, compositions or a range of products are manufactured such as: annealed glass, tempered glass, laminated glass, armored glass, safety glass, thermo acoustic glass, reflective glass, decorative glass, silk-screened glass, sandblasted glass, thermo-toughened glass, vitrified glass, lacquered glass, satin glass, printed glass, reinforced glass

Flat glass needs to be cut before processing, Glass cutting solutions can be selected based on the type of glass, its thickness, and the desired cutting accuracy and shape.

Flat glass needs to be cut before processing, Glass cutting solutions can be selected based on the type of glass, its thickness, and the desired cutting accuracy and shape. 


Here are some common glass cutting methods:


  • Manual cutting: 

    For thinner glass that does not require high precision, you can use a glass knife for manual cutting. A glass knife is a simple and low-cost tool suitable for glass 3-6 mm thick. During use, the angle and cutting pressure of the cutting wheel need to be adjusted according to the thickness of the glass to ensure that the cut marks are smooth, even and continuous.


  • Mechanical Cutting: 

    For glass that is thicker or requires greater precision, a mechanical cutting machine can be used. The mechanical cutting machine can adjust the angle of the cutting wheel and cutting pressure as needed, and can control the cutting speed and cutting depth to obtain higher cutting accuracy and quality. The mechanical cutting machine is suitable for glass with a thickness of 1-19 mm, and the accuracy can reach 0.03 mm.

    The CNC automatic glass cutting machine is mainly used in the processing of flat glass, which can quickly and accurately load sheets, cut straight-line,special-shaped glass and air-floated mechanical breaking sheets.


  • Waterjet cutting: 

    For situations where special-shaped glass needs to be cut, a waterjet cutting machine can be used. Waterjet cutting machines use high-pressure water flow to cut glass and can cut various shapes, including circles, ovals, concave, convex, etc. Water jet cutting machines have the advantages of fast cutting speed, high precision, and no thermal impact on materials, but they require high equipment costs and operating skills.


  • Laser cutting: 

    Laser cutting is also a high-precision and efficient glass cutting method. Laser cutting machines use high-energy laser beams to illuminate the glass surface, causing the glass to instantly melt and cut. Laser cutting has the advantages of fast cutting speed, high precision, and smooth cuts, but it requires high equipment costs and operating skills.


When choosing a glass cutting method, factors such as cutting accuracy, speed, cost, and equipment availability need to be considered based on the specific situation. At the same time, no matter which cutting method is used, attention must be paid to safety to avoid harm to the operator and the surrounding environment.
