What is an abrasive to go machining?

The process of abrasive jet machining uses high water pressure itself or with an abrasive additive to supply the strength of the nozzle cutting of £ 30,000 to £ 60,000 per square inch (dogs). This extremely concentrated beam of water energy emits from the machine workpiece designed to help with custom cutting of numerous materials. The water itself cuts softer materials such as foam, rubber and plastic; The cold cutting process creates small heat, allowing to cut flammable materials without a zone affected by heat. Adding abrasives allows reduction of accurate patterns in stronger materials such as metals, glass and tiles. High precision cuts produce complex shapes and patterns with neat edges. These machines cut stone, marble and glass, although tempered glass, like from the windscreen of the car, cannot be without breaking. Diamond Enticated material that cannot be reduced by this process. These machines are used in manufacturing and machining and cut metals such as aluminum for production; in crafts such as decorative glass cutting; andIn construction, formation of products such as their own tiles and unloaded marble medallions.

Forcing ordinary water from the water supply at high pressures through an extremely narrow channel creates a cutting current that removes the target material by erosion. These strong workpieces usually occupy professional workshops and machinery, often work as a process of finishing due to their slow level of removal. The device uses pumps; They draw not only water, but up to 250 amps, just to start abrasive to drive machining, and use up to 50 amps during the process.

The

machine works by compressing gas through a mixing chamber, perhaps with grenade abrasive, a hard mineral and a safe, natural abrasive material. The gas flows through a convergent divergent nozzle, a mixing chamber and a fixed or pocket convergent nozzle. Resistant nozzles are made of hard materials such as synthetic sapphire or tungsten carbide. WITHAPPHIRE nozzles have a life of about 300 hours, while tungsten carbides have a short life of 12 to 30 hours.

The high -speed beam of water leaves the nozzle and creates a vacuum that attracts abrasive with a mixing tube. This current accelerates the particles to the cutting speeds through the outlet opening with a diameter of 0.007 inches up to 0.02 inches (0.18 - 0.4 mm) at speeds of about 600 km / h (966 km / h) and the sound speeds are approaching. Factors that may affect abrasive machinery include material properties and desired shapes. In addition, the water pressure and the abrasive type must be checked to achieve the desired cut, which is also affected by cutting speed.

Sometimes it is called water lasers, abrasive ride machining processes share the concept of their own computer controlled extraction shaping with other types of jet machines. They may include electrical drain (EDM) and flame, laser and plasma cutters. Innovation continues to develop a cryogenic abrasive machinery with2 to minimize waste and facilitate environmental costs. Increasing availability of water jets in local workshops causes this process to become an affordable option for fans. Complete adjustment of pumps, positioning surfaces, tanks and feed systems mean that these sometimes cumbersome machines are mainly occupied by professional workshops.
