[0002] When smelting, in order to detect whether the smelted steel material meets the standard, the molten steel is generally extracted, then poured into a fixed mold to form a smelting sample, and then the smelting sample is cut by a metallographic cutting machine, and the cut surface is detected. In order to facilitate molding and demolding, the mold before the furnace is generally a circular table-shaped mold with a wide upper cavity and a narrow lower cavity, so the smelting sample after shaping is a circular table-shaped sample. Since the base table of the existing metallographic cutting machine is a water platform, and the clamping surfaces on both sides for clamping the workpiece are flat surfaces, when clamping and cutting the circular table-shaped smelting sample, due to the limited contact surface, the smelting sample is fixed more troublesome, often unstable or displaced during cutting or the thin head of the smelting sample falls down, thereby causing the cut surface to be difficult to be parallel to the front and rear end surfaces of the smelting sample, but an inclined surface, thereby affecting the accuracy of the later detection of the steel sample.
