Large aluminum plate processing plants have opening machine (straightening machine). That is, it is composed of a complete set of aluminum plate straightening machinery by drawing machine, cutting machine and platform.

1) Mechanical polishing: mainly with polishing wax polishing wheel on the surface of the aluminum alloy shell processing, which can reduce the surface roughness of the aluminum alloy shell, make the surface smooth, obtain bright or mirror effect, can effectively repair the aluminum alloy shell surface scratches and scratches.
2) Electrolytic polishing: electrolytic polishing in the use of chemical reaction to electrolytic polishing as the anode, insoluble metal as the cathode immersed in the electrolytic cell, through direct current, dissolve the anodized aluminum, aluminum disappeared from the aluminum shell, restore luster.
3) Chemical polishing: chemical polishing can be used as a pre-treatment process for protective decorative electroplating, and can also be used as a pre-treatment process for chemical film formation such as phosphating. If the anti-rust passivating water solution is dipped before painting, the aluminum oxide on the surface of the aluminum profile shell can be eliminated.
4) Ultrasonic polishing: ultrasonic polishing is the use of tool section for ultrasonic vibration, through the abrasive suspension polishing brittle hard materials a processing method. The workpiece is put into the abrasive suspension and placed together in the ultrasonic field, and the abrasive is ground and polished on the workpiece surface by relying on the oscillation of the ultrasonic wave.
5) Fluid polishing Fluid polishing technology needs to rely on the flow of liquid and its carrying particles to wash the surface of the workpiece to achieve the purpose of polishing. Hydrodynamic grinding is hydraulically driven, and the medium is mainly made of special compounds with good flow under low pressure and is mixed with abrasives, which can be silicon carbide powder.
6) Magnetic grinding polishing Magnetic grinding polishing is also one of the polishing technologies involved in aluminum shell processing, the use of magnetic abrasives under the action of magnetic field to form an abrasive brush, grinding the workpiece. This method has the advantages of high processing efficiency, good quality and easy control of processing conditions. With suitable abrasive, the surface roughness can reach ra0.1μm.

The aluminum plate can be bent, but it is necessary to pay attention to whether the alloy state of the aluminum plate is soft or semi-hard or full hard, and the thickness of the size, CNC bending machine high precision and high efficiency bending aluminum plate.
