Glass is an amorphous inorganic non-metallic material, generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw material, and a small amount of auxiliary raw materials are added. of. Its main components are silica and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate double salt, which is an amorphous solid with random structure. It is widely used in buildings, used to block wind and light, and belongs to a mixture. There are also colored glass mixed with oxides or salts of certain metals to show color, and tempered glass obtained by physical or chemical methods.
The working methods of linear edging machines (straight edge machine, round edge machine, bevel edge machine) are all grinding by clamping the glass by the front and rear platens and driving its linear motion. When using it, you must pay attention to two points:
①The joint surfaces of the front and rear pressure plates and the guide rails should be lubricated frequently, otherwise the normal service life of the machine will be affected due to the premature wear of the front and rear pressure plates and the working surfaces of the guide rails. Although some models have automatic lubricating devices, it is necessary to check whether the lubricating pipeline is smooth;
②The clamping force should be appropriate when clamping the glass, too loose will affect the grinding quality, too tight will increase the load of the machine, easy to produce the phenomenon of shaking and crawling, and it is easy to break the glass when grinding thin glass. The clamping force can be tested by clamping a piece of slightly larger glass on the machine, that is, clamping the glass in the middle of the machine, and moving the glass with both hands when the machine is stopped.
