Description

Technical Field

[0001] The utility model relates to the technical field of metal cutting and processing, in particular to a cooling and temperature reduction component for shaft core cutting and processing. Background Art

[0002] A large amount of heat is generated during metal cutting. This heat mainly comes from the friction between the cutting tool and the workpiece, plastic deformation and energy consumption during the cutting process. In order to prevent tool wear, improve the surface quality of the workpiece and increase cutting efficiency, cooling is required during metal cutting.

[0003] During the cutting process, the metal is usually cooled by spraying cutting fluid (cutting fluid is a fluid used in the metal cutting process, mainly for cooling and lubrication, and can be water-soluble or oil-based). The shaft core (or shaft core) refers to the internal structure or central part of the shaft, which is used to support and transmit the rotational torque. The shaft core is cylindrical. When the shaft core is cut, the existing cutting fluid spray nozzle cannot spray around the shaft core to cool it, so the cooling effect of the shaft core cutting is poor. To this end, we propose a cooling component for shaft core cutting. Utility Model Content
