Polishing machines: Polishing machines have a wide variety compared to grinding machines and polishing machines, mainly divided into 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 to match the polishing wheel for polishing. Due to the stronger professionalism in efficiency, automatic polishing machines have different types of machinery for different products, resulting in a wide variety of automatic polishing machines. For example, the surface polishing treatment of hardware products, flat products, round tubes, square tubes, and other products can achieve the effect of metal surface to mirror surface. It is a processing equipment that can achieve a bright effect in surface treatment.
Grinding machine: also known as vibration grinding machine, it is a grinding method that reduces surface burrs and edge burrs of the workpiece by friction between the workpiece and abrasive materials such as stones. It is mostly designed as a drum type shape. Suitable for surface polishing, chamfering, deburring, polishing, and glossy polishing of small and medium-sized workpieces. After treatment, it does not damage the original shape and dimensional accuracy of the parts, can remove internal stress of the parts, and improve the surface smoothness and accuracy of the parts. For example, the surface preliminary treatment of commonly used products such as Buddha beads, small die-casting parts, and screw caps all require the use of this vibration grinder.
Grinding machines: According to power classification, they can be divided into pneumatic grinding machines and electric grinding machines. According to mechanical scale, they can be divided into seated grinding machines and portable grinding machines. Suitable for surface grinding of iron plate, wood, plastic, tire industry, fine polishing of ships, automobiles, grinding tools, aviation industry, deburring, rust removal, paint removal, and other operations. Iron plates, wooden boards, clinker, etc. are generally polished using a seated grinder, while larger surfaces such as cars and ships are generally polished using a portable grinder. Through the appeal, it is not difficult to find that the three types of machinery that I often confuse in the industry actually have huge differences in the processing field. When distinguishing, we can also distinguish based on their specific processing field or the effect of the finished product. Polishing, as the name suggests, requires processing the product to a bright surface, while grinding involves treating impurities and burrs on the surface of the product to achieve smoothness. Polishing mainly involves making the surface of the product flat.
