  Application field of abrasive fluid polishing machine

 Extrusion and grinding is to remove metal material, deburring and rounding the intersection of parts to achieve the purpose of fine machining. Abrasive flow machining has accuracy, stability and flexibility. It is widely used in automobile industry and various manufacturing industries. Its most fundamental advantages are: accessible parts complex and difficult to enter parts; polished surface uniform, complete; batch parts of the same processing effect. These processing characteristics make the performance of parts improved, life extension, while reducing the complexity of manual labor, greatly reducing labor intensity. If the automobile intake pipe is manually polished, the internal surface can only be cut, polished and welded. With abrasive flow machining, the inner surface can be polished without cutting and opening. In addition to being used as a polishing tool, abrasive flow technology can also be used for micro-grinding of parts with extremely strict surface shape tolerance and quality requirements.
Application: abrasive flow machining is suitable for machining different parts and sizes. Small to 0.2 mm hole or 1.5 mm diameter gear, up to 50 mm diameter spline channel, or even 1.2 M turbine impeller. Machine tools for machining large parts can be equipped with gyrators or transmission tracks.
 
        
The process has been widely used in automotive parts finishing: intake and exhaust pipe, intake valve, booster chamber, injector, nozzle, cylinder head, turbine shell and blade, spline, gear, brake, etc. For example: rough cylinder head castings in a special two-station abrasive flow production line, the hourly production capacity can reach 30 pieces, roughness from Ra4 or Ra5 micron to Ra0.4 micron, can reduce exhaust emissions by 7%, engine power increased by 6%, mileage increased by 5%.
In recent years, microporous abrasive flow machine developed and developed is unique in the processing of fuel injectors. It is based on the relationship between extrusion pressure, abrasive temperature and viscosity. During processing, when the setting flow rate of the nozzle reaches, the processing stops automatically. The processing time is about 10 seconds, and the flow divergence can be controlled at + 1%. The flowmeter and the high pressure cleaning equipment are also matched with this processing equipment. The equipment can provide single station or multi station according to the needs of users. It can also be a complete system with mechanical hands, including processing, measuring and cleaning.
        
      Abrasive flow polishing machine is suitable for machining aerospace parts.
Abrasive flow polishing machine is suitable for processing aerospace parts,  and national defense industries, using a large number of various alloy steel, stainless steel, aluminum alloy and titanium, these large and small equipment and various parts, high precision, good performance, especially aerospace equipment, require surface heat resistance, wear resistance Corrosion resistance and other properties are high, so the surface is polished and polished. Electrochemical polishing is an important means of construction.  
        
        In addition, many refractory and non-ferrous metals such as molybdenum, tungsten, niobium and tantalum are also used in aerospace industry because of their excellent properties. Tungsten and molybdenum have high melting point, high stiffness, high temperature strength and high temperature hardness, strong thermal shock resistance and corrosion resistance in various media, good thermal conductivity and conductivity, which determine their use in this field (these metals are expensive, other industries are limited). For example, tungsten-nickel-copper and Tungsten-Nickel-Iron high-density alloys can be used to manufacture gyroscope rotor, armor piercing warhead, aircraft and rocket control wheel balance hammer, radiation shield, etc. In the aerospace industry, the nozzle of solid rocket motor (SRM) is uncooled, which requires high temperature resistance, high heat erosion resistance and corrosion resistance, and tungsten is a suitable nozzle throat lining material. Tungsten can be used in solid rocket exhaust pipe, missile steering rudder assembly, air rudder leading edge, meteorological rocket loaded into the aircraft head, ion motor with porous plates to make cesium ionizer, in solar electric propulsion system with tungsten to make carburetor.
With the development of aviation industry and the progress of technology, the transmission accuracy of gears is more and more demanding. The burr removal of gears is particularly important because it affects the transmission stability, noise level and gear load uniformity. As an early automatic intelligent grinding equipment research and development company in China, Zhejiang Diyoole Abrasive Flow Equipment Co., Ltd. for gear, Aerospace accessories products deburring, polishing equipment development and design.
