Description

Technical Field

[0001] The utility model relates to the technical field of CNC machine tool cutters, in particular to a CNC turning tool assembly. Background Art

[0002] A lathe is a machine tool that uses a tool to perform turning processing on a rotating workpiece. During the processing, the high-speed rotation and friction will generate heat, causing the temperature of the tool itself to rise rapidly, which greatly affects the life of the machine tool processing tool. In order to ensure the service life of the tool, most of the existing technologies use air pumps or coolants to cool the tool, and usually use a fixed angle for cooling. The cooling device is usually fixed on the processing tool fixing seat, and the outlet position of the air or coolant cannot be changed. The control is very inconvenient, the cooling effect is not ideal, and the energy consumption is high. For example, when coolant is used to cool the tool, the cooling device uses a water spray pipe to spray coolant to the turning tool for cooling. Since the movement process of the turning tool and the water spray pipe is inconsistent, the tool head lacks coolant and cannot be fully cooled, which greatly reduces the life of the turning tool. In particular, when using an internal hole turning tool to process the inner hole, the tool head cannot be fully cooled due to lack of coolant, resulting in poor surface finish of the inner hole and difficult to control the size. Every time the turning tool is replaced, the position of the water spray needs to be readjusted, which results in high labor intensity and low efficiency for the workers. Moreover, if the water spray pipe is not placed in the right position, it will also cause the chuck, the turning tool holder and the water spray pipe to collide, resulting in accidents.
