Jade has to go through in order to become polished and waxed smooth jade jade processing of the four basic steps of styling products or styles are processed steel. Jade processing , although there may be many different processing details , but the overall timing are nothing more than sawing, pondering and polishing several big steps. 1 , jade sawing sawing sawing machine is in jade material will be divided into the appropriate shape and size , so that the rational use of jade craftsmen . This is the first step of jade processing . The procedure involves sawing Grinding Pin and blade. Sawing tools used since ancient times , great changes have taken place hair . Sediment from the human -driven saws to power-driven cutting machine, which experienced a long period of years . Modern large-scale use of the saw , there are a variety of electric saws used for different purposes , such as aniseed cutting machines ( including open stone machine, slicing machine ) , small cutting machine, multi-blade cutting machines and so on. Blade types also differ . Saw blades are a variety of modern hot rolling a cast saw blades and blade plating , diamond powder, hot cast or rolled directly on top of the blade edge , so that the cooling water can quickly saw only on any hardness of jade cutting, high efficiency. Especially rolling - plated blade , because of its low prices, specifications , thin blade, loss of material when cutting a minimum , once born , they are widely used. 2 , jade pondering is the second step of jade processing . The key thing is whether or not the merits of jade quality modeling pondering . Sato process involves grinding and abrasive . Abrasive materials is an important jade processing . Ancient craftsmen to do with the riverbed sand abrasive . Jade wondering is there with the abrasive through to carry out . There are generally two forms : the loose abrasive particles pondering and pondering in fixed abrasive . The former is made by rotating the abrasive water suspension attached to some tools ( such as cast iron flat disc ) , the means of disc and pressure is applied to the abrasive material on jade jade be wondering, pondering this form is the traditional method often used ; latter through the resin, metal , ceramic, etc. the binding agent is formed on the fixed abrasive certain abrasive substrate , and thus be refined jade , jade processing more modern use this method. Such as silicon carbide abrasive silicon carbide abrasive powder made known , including the known types of wheels, sand bar , emery cloth, sandpaper , etc. The most commonly used silicon carbide wheel . Diamond abrasive powder made known diamond abrasive , also known as diamond powder abrasive, including diamond grinding wheels, diamond shaped diamond abrasive disc and so on . There are flat -shaped diamond grinding wheel, grinding wheel, curved wheel, single- bevel wheel variety . In short form of abrasive are designed according to the specific form of the production of refined to meet the processing needs of a variety of jade pieces , relatively traditional pondering concerned, greatly reduces the processing cost and labor intensity , its efficiency is not self-evident.
