Abrasive flow milling, also known as abrasive flow machining (AFM) or extrusion honing, is a precision finishing technique used in a variety of industries. Abrasive flow machining is performed by flowing back and forth under pressure loaded with abrasives, viscoelastic compounds or abrasive media, through fixtures Silicon Nitride and over areas to be polished, deburred and rounded. Grinding media suitable for internal and external deburring and polishing abrasive flow mills provide practical material removal: polishing, deburring and edge filleting. Including cross-hole deburring (cross-hole), edge deburring, and workpieces with complex areas and inaccessible intersections, suitable for single-piece and mass production of extrusion mold plastic profiles.
Shot peening is done to change the mechanical properties of the metal, not to remove surface defects. During shot peening, pressurized air sprays tiny beads of metal or plastic at a surface at high speed. These particles form small pits on the surface of the object. Under these pits, compressive stress is created, which replaces the tension in the item. stress, thereby increasing the length. Compressive stress makes the surface Ceramic Part stronger and helps resist erosion from fatigue, wear, cracking and cavitation. This process typically involves steel, ceramic and glass media.
Vibration polishing is possible on almost all materials such as plastics and metals, as well as workpieces produced by different manufacturing processes. From a uniform surface pattern, to a flattening process with low roughness, to a high gloss finish, it can be perfectly achieved.
Vibration finishing machines are ideal for surface finishing of small and medium parts. Whether you need to deburr laser cut parts, deburr die cast parts, or finish before plating, vibratory finishing machines are always your first choice. Suitable for smoothing the surface of plastics and ceramics. It provides gentle surface finishing without altering the part surface geometry. Magnetorheological Polishing MRF technology is an optical surface mechanical polishing process, which realizes the flexible design of high-quality precision optical devices by utilizing the magnetorheological properties of material components. Targeted localized material removal corrects optical surfaces and achieves the lowest surface roughness values (Rq < 0.3 nm). Due to the wide variety of optical devices that can be fabricated, the MRF refinement process has a wide range of applications. Different geometries in the short-wave and long-wave ranges are easily realized. Therefore, polishing within the framework of MRF technology can be performed on classical optics such as spheres as well as on more complex surfaces such as aspheres or freeforms. For example, microscope lenses are polished using MRF technology to keep scattered light to a minimum and produce sharp images. The demands placed on the optics installed in laser systems are also very high, since they are exposed to particularly high environmental influences, such as the sun, and are therefore subject to particular heat. In order to guarantee optimum function, optical components require perfect optical surfaces. Laser polishing is a new type of material surface treatment technology that appeared with the development of laser technology. It is a kind of equipment that uses fiber Alumina Ceramic Block laser beam to polish processing components. The equipment adopts an integrated overall structure and has no chemical pollution and working noise. , has the characteristics of high efficiency, long life and less maintenance, which greatly saves manpower and energy consumption.
The laser polishing machine fundamentally solves the workpiece surface with complex shape and appearance that is difficult to be solved by traditional polishing technology, thus providing the possibility of automatic processing, so the laser polishing machine is a promising new material processing. technology. Ultrasonic Precision Cleaning Ultrasonic cleaning using aqueous liquids is often used for the final cleaning of precision components. Optical glass, ceramic, injection/plastic extrusion moulds with burnt residues can be cleaned very effectively by the action of ultrasound and the right combination of cleaning agents. In the ultrasonic frequencies of 120 kHz and megasonic, it is mainly used in precision optics for cleaning very sensitive parts such as wafers. The power of ultrasonic cavitation is low, so these frequencies are used to clean parts to remove dust in the final cleaning.
