Description

technical field [0001] The invention relates to a cooling device, relates to the technical field of milling machine cooling, in particular to a cooling device for a high-speed numerical control milling machine. Background technique [0002] CNC milling machine is also called milling machine. The English meaning is a milling machine controlled by an electronic digital signal. CNC milling machine is an automatic processing equipment developed on the basis of general milling machine. The processing technology of the two is basically the same, and the structure is somewhat similar. CNC milling machines are divided into two categories without tool magazine and with tool magazine. Among them, the CNC milling machine with tool magazine is also called machining center. There are following problems at prior art: [0003] 1. A high-speed CNC milling machine has the problem that the internal parts are damaged due to the temperature of the high-speed CNC milling machine being easily...
