The HZPG-250 vibration polisher uses high-frequency micro-vibration to perform light and fine polishing on the surface of the sample, minimizing the mechanical stress during the polishing process; it is suitable for preparing high-quality polished surfaces on various materials, including electron backscatter diffraction analysis (EBSD) applications, atomic force microscopy (AFM) analysis, scanning electron microscope (SEM) analysis and other pre-sample preparations. At the same time, vibration polishing is suitable for fine polishing and final polishing of most materials due to its excellent mechanical-chemical polishing effect, especially for soft and tough materials such as pure titanium and titanium alloys, pure aluminum and aluminum alloys, pure copper and copper alloys, nickel-based alloys, high-temperature alloys, etc. Different from traditional vibration polishers, this machine uses a spring plate and a magnetic attraction motor to generate left and right vibrations. Since there is an angle between the spring plate and the vibration plate, the sample can move in a circle in the polishing plate.  This structure can produce vibrations in an almost completely horizontal direction, greatly increasing the time that the sample contacts the polishing cloth. During the polishing process, no additional damage layer or deformation layer is generated for the sample, and defects such as embossing, embedding, and plastic rheology can be effectively removed and avoided. The machine has a novel and beautiful appearance and is easy to operate. The vibration frequency and vibration voltage can automatically adapt to the vibration intensity. Multiple samples can be placed at one time without the need for personnel on duty. After setting the parameters, the user can leave and wait for the sample to automatically complete the vibration polishing. It is widely used in major enterprises, institutions, and scientific research institutions.
