Description
technical field [0001] The invention relates to a cooling device, in particular to a frequency conversion temperature control system with hot steam compensation for a numerically controlled machine tool. Background technique [0002] With the rapid development of the CNC machine tool industry, the machining accuracy of machine tools is getting better and better, and the machining speed is getting faster and faster. In order to adapt to such high-precision, high-speed work requirements, modern CNC machine tools require more and more precise temperature control in various functional components. For example, high-speed electric spindles, hydrostatic spindles, linear motors, hollow screw screws, turntables, hydraulic systems, cutting fluid systems, lubrication systems, etc. all require high-efficiency and high-precision temperature control systems. [0003] Most of the previous temperature control systems used a fixed frequency method to cool various functional components. The ...
