Brief introduction: This machine is suitable for cutting irregular general metallographic sample materials such as cylinders and polygons, in order to observe the metallographic and petrographic structures of the materials. Adopting a double shell fully enclosed structure. It can ensure absolute safety during sample cutting. This machine is equipped with a strong cooling system. The use of prepared coolant can remove the heat generated during cutting, avoiding overheating of the sample and burning the sample tissue. During cutting, the sample can be rotated at any angle to avoid micro burns on the surface during cutting. At the same time, the cutting cross-section has been increased, improving the utilization rate of cutting grinding wheel blades.
