The three types of machines, polishing machines, grinders, and grinders, are actually completely different types of machines. Many people will be confused, including some authoritative platforms. In fact, although the three have similar principles and similar functions, there are big differences because they are almost non-competitive. Below we will elaborate on the differences between the three to facilitate our identification.
polisher:
Mainly use polishing wheel friction and polishing wax to make the metal surface smooth and even mirrored. The motor drives the sponge, wool, or grinding wheel polishing disc installed on the polishing machine to rotate at high speed. As the polishing disc and the polishing agent work together and rub against the surface to be polished, the purpose of removing paint pollution, an oxide layer, and shallow marks can be achieved. Compared with grinders and grinders, there are many types of polishing machines. The main categories are manual polishing machines and automatic polishing machines. The type of manual polishing machine is relatively single, mainly consisting of a motor and a single shaft with a polishing wheel for polishing. As automatic polishing machines are more professional in the pursuit of efficiency, there will be different machines for different products, resulting in more types of automatic polishing machines. Example: The surface polishing treatment of hardware products, flat products, round pipes, square pipes, etc. can make the metal surface achieve a mirror effect. It is a kind of processing equipment that can achieve the brightest effect in surface treatment.
Grinding machine:
Also known as a vibrating grinder, it is a grinding method that reduces burrs and edge thorns on the surface of the workpiece through the friction between the workpiece and the abrasive materials such as stones. Most of the grinding method is a drum-type shape design. Suitable for surface polishing, chamfering, removing burrs, polishing, and gloss polishing treatments of small and medium-sized workpieces. After treatment, the original shape and dimensional accuracy of the parts will not be destroyed, the internal stress of the parts can be eliminated, and the surface finish and accuracy of the parts can be improved. For example, the most commonly used surface treatments such as Buddhist beads, small die-casting parts, screw caps, and other products require this kind of vibrating grinder.
polisher:
According to the power classification, it can be divided into pneumatic grinders and electric grinders. According to the mechanical scale, it can be divided into sitting grinders and portable grinders. It is suitable for surface grinding of iron plate, wood, plastic, tire industry, fine polishing, deburring, rust removal, and paint removal in ships, automobiles, abrasive tools, and aviation industries. Seated grinders are generally used for iron plates, wood boards, clinker, etc., while larger surfaces such as automobiles and ships are generally polished by hand.
Through the understanding of the appeal, it is not difficult to find that the three machines that I often confuse in the industry actually have huge differences in the processing field. When we distinguish between them, we can also distinguish according to their specific processing fields or the final effect of the finished product. . Polishing, as the name implies, needs to process the product to a bright surface. Grinding is to process impurities and burrs on the surface of the product to make it smooth. Polishing is mainly to make the surface of the product smooth.
