After purchasing the multi function computer stone copying machine, we should not only pay attention to its working ability, but also to the internal parts of the multi function computer stone copying machine, because once the parts have problems, the whole multi function computer stone copying machine will inevitably fail over time.

During the working process of the multi function computer stone copying machine, the phenomenon that the size and shape of the parts of the multi function computer stone copying machine change due to the force is called deformation. Deformation of metal in multi function computer stone copying machine includes elastic deformation and plastic deformation. When the stress caused by the load exceeds the elastic limit and continues to increase, the material may produce plastic deformation. When the stress exceeds the strength limit, the parts of the multi function computer stone copying machine will break.

In the multi function computer stone copying machine, the knife head is an indispensable tool for processing, and plays an important role. Because the main function of the multi function computer stone copying machine is to process and grind stone, and the hardness of the stone itself is relatively high, so the wear degree is relatively large, which puts forward certain requirements for the quality and anti-wear degree of the tool head of the multi function computer stone copying machine.

From the characteristics of material itself, the cutter head of multi function computer stone copying machine can be divided into loose and tight organization. The former is suitable for grinding of large plane and contact surface, and processing of soft stone workpieces, while the latter is suitable for finishing workpieces with high surface finish requirements. The main material of the cutter head of the multi function computer stone copying machine is cemented carbide. Its grain size determines the processing accuracy of the stone surface and the requirement of production efficiency. Rough or semi-finish machining has low hardness and high ductility. The materials with high toughness should be machined with coarse-grained or medium-grained cutters. On the contrary, the materials with high hardness and brittleness are suitable for fine-grained cutters.
