Abstract

The present invention relates to a method of cutting a tempered glass and is applicable to cutting a tempered glass which has a tempered layer on the upper and lower surfaces respectively. The method comprises the following steps: first preparing a heater which has a heating area with a temperature sufficient to break the tempered layers; then moving the heater on the tempered glass to mark a cutting path, which is formed by contacting the tempered glass with the heating area along the cutting path to break the hardness of the tempered glass; then preparing a glass cutting tool capable of cutting the tempered glass with lessened strength; and finally using the glass cutting tool to cut the tempered glass along the cutting path. Accordingly, the portion of the tempered glass which has been marked by the heating area will have its hardness of the tempered layers lessened by the high temperature, so the tempered glass can be cut by the glass cutting tool, thereby allowing the tempered glass to be cut into a proper size according to the demand to satisfy the need in use.

[Prior Art] Glass is often used in furniture, decoration, compartments, and various instruments and machines that require perspective. 'It has the advantages of being transparent and easy to clean, so it is widely used to reduce costs'. Uniform size production, and then use relevant cutting tools such as diamond knives, gear knives, etc. to cut into the required size. However, the general glass has a risk of being broken by the material and causing a dangerous acute angle. For safety considerations, the glass can be reinforced to increase the strength of the glass, and the strengthened broken H is called tempered glass. At present, there are two main methods of strengthening glass, physical and chemical, in which the physical mode is rapid cooling by heat treatment, and the chemical mode is ion exchange. In the case of using a chemical ion exchange method for the glass, since the reinforcing layer is only formed on the surface of the glass, it can be cut after strengthening, which is quite convenient for use 'but in order to obtain sufficient strength, the general reinforcing layer has a certain thickness' The depth of the glass cutting tool must be cut to exceed the strengthening layer to cut the tempered glass, and the hardness of the strengthening layer is quite high, which will cause the glass cutting tool to wear quickly, and if the depth of the reinforcing layer is greater than the cutting depth of the glass cutting tool, it will result in The broken glass cutting tool cannot cut the reinforcing layer, in other words, it will not be able to cut the tempered glass. 099146049 Form No. A0101 Page 3 / Total 16 Page 0992079203-0 201226345 [0005] [0006] [0008] [0008] 099146049 At present, people have used vibrating knives to cut tempered glass, vibrating knives can be cut to strengthen the depth without strengthening Glass, when the depth of reinforcement is too deep, if the depth of reinforcement is more than 10 microns, it will cause the tempered glass to be cut smoothly even with a vibrating knife, which will cause troubles in the process. As described above, at present, after strengthening the tempered glass, since the hardness of the reinforcing layer is high, it is necessary to use a glass cutting tool having a sufficient cutting depth, and the glass cutting tool is relatively easy to wear, and at the same time, for tempered glass having a depth of more than 10 μm, It is not effective to cut, and it is difficult to meet the needs of the process.
