First, Kaisuke
Generally, the opening push knife or the glass knife is used for the opening. The size error range is generally controlled at ±0.5mm. When the glass is opened, it is generally required to reserve the size for the edging process according to factors such as shape and thickness. Position, different thickness of the glass to stay different, generally 2-3MM, the extra-shaped additions have to be added, the opening does not need to add. Due to the sharp opening of the opening, the factory generally does not process other processes, so it needs to be specially noted. Shaped opening requires a 50 mm opening of each profiled edge for square opening, and then a second opening according to the profiled template.
Second, straight edge
Machining with straight edge edging machine (single-side machine and double-sided machine), including rough grinding, fine grinding and polishing; linear straight edge including straight edge, straight round edge, straight duckbill edge (≥6mm), special angle requirement And the cost of edging processing for special size requirements is different; the frame and the glass that does not need to be tempered can be considered without edging, and the glass that needs to be tempered can be considered for rough grinding, and the glass without edging needs to consider employee operation. And the safety hazards of the use of the room.
Third, chamfering
Tempered glass processing using special machine or chamfering machine; reverse safety angle (R1-R3), rounded, bevel chamfer, special chamfer; glass that needs to be tempered can not be cut at right angle, need round diameter The size is larger than the thickness of the glass, otherwise it will also cause the glass tempering process to explode.
Fourth, tempering (enhanced)
Tempered glass processing is a kind of safety glass. After glass tempering, there is no change in appearance quality, thickness, light transmittance and the like. Tempering is to heat the glass in a tempering furnace to a temperature exceeding 700 °C and then cool it with a blower to change the molecular structure of the glass, forming compressive stress on the surface, increasing the impact strength of the glass (4-5 times), and maintaining the temperature difference of 200 °C and improving The purpose of security.
The glass tempering of 3 mm thickness is the most difficult. Generally, the imported tempering furnace is required, and the tempering cost is relatively high. The tempering equipment of 3 mm or less and small-sized glass tempering requires special tempering equipment; impact resistance, pulverized particle size and quantity, and transparency. It is the main indicator of tempering quality; after glass tempering, the processing technology of breaking glass body such as opening/frying/drilling is not carried out.
