Mainly for pipes, plates and small cross-section bars with good material plasticity. Such as plastic pipe, copper pipe, aluminum pipe, plastic plate, aluminum plate, copper rod, etc. for fixed length cutting. Chip-free cutting is the use of material plasticity, the use of tools to make the material in the cutting of large plastic deformation, material molecules due to plastic deformation heat, molecular gap increases and separation, so as to achieve chip-free cutting. In terms of appearance, the "cutting" elements are refined, the proportion of equipment blocks is divided, the appearance identification characteristics of equipment are shaped, and the sublimation of the market-oriented image of the product is considered while the man-machine is considered. It is mainly aimed at pipes, plates and bars with better plasticity. Such as plastic pipe, copper pipe, aluminum pipe, plastic board, aluminum board, copper bar and so on for fixed-length cutting. Chip free cutting is to use the plastic material, with the tool to make the material at the cutting place appear large plastic deformation, the material molecules due to plastic deformation heat, molecular clearance increased and separation, so as to achieve chip free cutting. In terms of appearance, the "cutting" element is extracted, the proportion of equipment block is segmented, the appearance identification characteristics of equipment are shaped, and the sublimation of product marketization image is taken into account while man-machine is considered.
