The difference between polishing machine, grinding machine and grinding machine

The three types of machinery, such as polishing machine, grinding machine and grinding machine, are actually completely different types of machinery. Many people will be confused, including some authoritative platforms, and even the same. In fact, although the three principles are similar, they are almost functional, but there are big differences because they have almost no competitive relationship. Below we will elaborate on the differences between the three to facilitate our identification.
Polishing machine:
Mainly using the polishing wheel to rub the polishing wax to make the surface of the metal smooth and even mirror. The motor drives the sponge or the wool polishing disc mounted on the polishing machine to rotate at a high speed. Because the polishing disc and the polishing agent work together and rub against the surface to be polished, the purpose of removing the paint surface contamination, the oxide layer and the shallow mark can be achieved.
Polishing machines are more numerous than grinding machines and grinding machines. The main categories are mainly manual polishing machines and automatic polishing machines. The type of manual polishing machine is relatively simple, mainly consisting of a motor and a single-axis assembly with a polishing wheel for polishing. Since the automatic polishing machine is more professional in terms of efficiency, it will have different machines for different products, resulting in many types of automatic polishing machines. For example: the surface polishing of hardware products, plane products, round tubes, square tubes, etc., can be the effect of the metal surface on the mirror surface. It is a processing equipment that can achieve the brightest effect in surface treatment.
Also known as the vibrating mill, the friction between the workpiece and the stone is used to reduce the burr of the workpiece surface and the grinding method of the side thorn. Most of them are drum type design. It is suitable for surface polishing, chamfering, burr removal, polishing and gloss polishing of small and medium-sized workpieces. It does not destroy the original shape and dimensional accuracy of the parts after treatment, which can eliminate the internal stress of the parts and improve the surface finish and precision of the parts. . For example, the most commonly used surface treatments for beads, small die-casting parts, screw caps, etc., require the use of such a vibrating mill.
Grinding machine:
According to the power classification, it can be divided into a pneumatic grinding machine and an electric grinding machine. According to the mechanical scale, it can be divided into a sitting grinding machine and a portable grinding machine. Applicable to iron plate, wood, plastic, surface grinding of tire industry, fine polishing of ship, automobile, abrasive tool and aviation industry, deburring, rust removal, paint removal, etc. Iron plate, wood board, clinker, etc. generally use a seat type grinding machine, while large surface grinding such as automobiles and ships is generally carried out by hand.
Through the understanding of the appeal, we can easily find that the three machines that I often confuse in the industry actually have huge differences in the processing field. When we distinguish, we can also distinguish according to the specific processing field or the final effect of the finished product. . Polishing, as the name implies, requires processing the product to a bright surface. Grinding is to treat the impurities and burrs of the skin of the product to a smooth finish. The polishing is mainly to smooth the surface of the product.
