Description

technical field

[0001] The present invention relates to the technical field of mechanical testing equipment and methods, more precisely, the present invention relates to a reliability testing device and method for a multi-working-condition loading cutting fluid centralized filtration system. Background technique

[0002] With the development of modern machining technology in the direction of green and intelligence, the supporting cutting fluid system is also changing to the direction of centralized filtration treatment of cutting fluid characterized by automation, high quality assurance, environmental protection and energy saving. At present, the production fields of large quantities of workpieces at home and abroad (such as auto parts, bearings and superfinishing, etc.) have gradually begun to change from the previous stand-alone filtering method to the centralized filtering method. The cutting fluid centralized filtration system is a circulation system that centrally filte...
