What do you know about eco-friendly polishers?

    Environmental protection polishing machine is to some objects of the surface of the coarse part of the wool, clean up, in order to achieve mirror effect. The key to the operation of the polishing machine is to try to obtain the maximum polishing rate in order to remove the damage layer produced during the polishing as soon as possible.

    The polishing is done in two stages. The purpose of rough polishing is to remove the polished damage layer. This stage should have the maximum polishing rate. The surface damage caused by rough polishing is a secondary consideration, but it should be as small as possible. The second is fine polishing (or final polishing), its purpose is to remove the surface damage caused by rough polishing, so that the polishing damage is reduced to the minimum.

    Polishing machine polishing, sample grinding surface and polishing disc should be absolutely parallel and evenly gently pressed on the polishing disc, pay attention to prevent sample flying out and due to too much pressure caused by new wear marks. At the same time, the sample should also rotate and move back and forth along the direction of the radius of the rotary table, in order to avoid the local wear of the polishing fabric too fast in the polishing process to constantly add polishing liquid or other polishing additives, so that the polishing fabric to maintain a certain humidity. Too much humidity will weaken the effect of polishing wear marks, making the hard phase in the sample appear to float convex and the non-metallic inclusions in steel and graphite phase in cast iron produce "trailing" phenomenon. Humidity is too small, due to friction heat will make the sample temperature, lubrication is reduced, grinding surface gloss, even appear black spots, light alloy will hurt the surface, there will be yellow image. After rough polishing, the grinding surface is smooth, but dull and dark. Under the microscope, there are uniform and meticulous wear marks, which need to be eliminated by fine polishing. The speed of the turntable can be increased and the polishing time should be better to remove the damaged layer of coarse polishing. After finishing polishing, the grinding surface is as bright as a mirror. No scratches can be seen in the microscope's bright field, but they can still be seen in the phase contrast lighting condition.

    The dust suction system is composed of the interlayer of the protective cover of the work roll and the dust suction duct in the fuselage. The induced draft fan will discharge the dust from the pipe through the duct. The outlet of the inner pipe is adjusted by the valve, and the dust is discharged into the dust filter device. The safety baffle is set in front of the work roll protective cover. When the hand hits, the feeding roller returns to the non-working position, the host stops working, and can resume normal work after restarting.

    The panel and the main board are controlled by single chip microcomputer, with automatic frequency search and locking function; The spark pulse of five grades and the pattern of ninety-nine sections and the intensification pulse are precisely generated by the microcomputer, and the spark pattern from matte to very thick can be simulated realistically in the pattern state. The hardening state can transfer tungsten carbide and other materials with high wear resistance to the work surface of the workpiece, thus greatly prolonging the service life of the workpiece; Because of the improved acoustic output circuit, the machine is very suitable for vibration grinding of rough surface with fiber oilstone and diamond file. It adds the voice prompt function with artificial intelligence, which provides a strong security guarantee for the correct and safe use of the machine.
