What is a Surface grinder?

As the name implies, a surface grinding machine is a grinding machine that grinds the surface of a workpiece and is the most used grinding machine at the processing site. It can be classified into several types according to the shape of the table on which the workpiece is set and the shape of the grindstone shaft on which the grindstone is set. Depending on the shape of the table, it can be classified into a square table type and a rotary table type. Furthermore, the square table type can be classified into three types according to the shape of the grindstone shaft. There is a horizontal axis type in which the grindstone shaft is horizontal to the ground, a vertical shaft type in which the grindstone shaft is perpendicular to the ground, and a portal type with a sliding part for moving the grindstone shaft head horizontally. There are many types of the same surface grinding machine, and there are advantages and disadvantages, so it is necessary to use them properly according to the purpose of grinding.

Application of Surface grinder

A grinding machine is a grinding machine that presses a workpiece against a grindstone that rotates at high speed and grinds it little by little. The amount of scraping is overwhelmingly smaller than that of milling, which cuts a flat surface. In the horizontal axis angle table type surface grinder, a cut is made when the table reciprocates from side to side, but it is 0.01 to 0.2 mm during rough grinding and 0.01 mm at the maximum during finish grinding, which is usually 0.005 mm. That's about it. However, by grinding with a grindstone, the machined surface can be finished with fine precision. Surface grinding machines are generally used for finishing workpieces such as hardened steel that have a planar shape.
