Description

Technical Field

[0002] CNC machine tools are one of the core equipment in modern manufacturing. They use digital control systems and can accurately process workpieces according to preset programs. They have the characteristics of high precision, high efficiency, and high degree of automation. CNC machine tools control the movement trajectory and cutting parameters of the tool through computer programming, and can process various complex shapes and parts with high precision requirements. They play a key role in many fields such as automobiles, aerospace, and mold manufacturing, greatly improving production quality and efficiency, and promoting the intelligent and modern development of the manufacturing industry. When using CNC machine tools, in order to make the CNC machine tools work longer, cooling devices are generally installed on the machine tools.

[0003] The cooling device of CNC machine tools usually consists of a water tank, a water pump, cooling pipes, cooling wires and a heat sink. Its working principle is as follows: the water pump extracts the coolant in the water tank and transports it to the cooling wire through the cooling pipe, taking away a large amount of heat generated during the cutting process. Subsequently, the heated coolant flows back to the water tank and is recycled again after being cooled by the heat sink. This circulating cooling method effectively controls the temperature of the machine tool and the workpiece, reduces thermal deformation, improves machining accuracy, and extends the service life of the tool and machine tool.

[0004] The existing machine tool cooling device for CNC machine tools has deficiencies in heat dissipation, which may result in the coolant being pumped into the cooling pipe by a water pump before being sufficiently cooled during use, causing the machine tool to not be sufficiently cooled, thereby reducing the working time of the machine tool; and the existing cooling device has deficiencies in coolant purification, which may cause impurities contained in the coolant to affect the cooling efficiency of the coolant, thereby causing the coolant to not be fully cooled. Therefore, in view of the above problems, a machine tool coolant purification circulation device for CNC machine tools is proposed. Utility Model Content
