The glass to the finished product to go through cutting, grinding edge, tempering and other steps. All kinds of product error requirements are not the same, so before the product to understand the error range of the product. Different error requirements are not the same as the processing technology. The error of the different machines is different.
Furniture glass and glass doors and windows on the error requirement is not so strict, error is about 2mm, the glass is using unilateral machining milling, a single machine can only grinding an edge, the glass of the error is relatively large. Some electronic products glass arranged inside the shell of the error in the 0.5 mm can be used bilateral machining processing and bilateral machine can control the size of a glass better. If the grinding edge master technology is hard error can be controlled within 0.3mm. Also mobile phone glass is error the most stringent requirements, the glass using CNC engraving machine for processing, the error can be controlled within 0.1 mm, using different types of glass processing in different ways, the processing before please confirm glass use and installation.
