Description

technical field [0001] The invention belongs to the technical field of heat exchange cooling, in particular to an electrostatic atomization cooling capacity evaluation device with adjustable nozzle space angle. Background technique [0002] The improvement of processing efficiency and processing quality is the goal that the machinery manufacturing industry is constantly pursuing. During the machining process, a large amount of cutting heat is generated in the cutting area, resulting in a sharp rise in temperature, which will quickly cause the scrapping of tools or parts. Usually, the cutting fluid is supplied to the cutting area with low pressure and large flow to control the temperature rise in the cutting area, reduce tool wear, and improve the quality of the machined surface. However, pouring cooling cannot really effectively cool the cutting zone, mainly in the following aspects: (1) It is difficult for the cutting fluid to enter the cutting zone; (2) The cooling of the...
