Description

technical field [0001] The invention relates to an electrostatic atomization device for nano-particle micro-lubrication cutting fluid in machining, in particular to a nano-fluid micro-lubrication electrostatic atomization controllable jet turning system. Background technique [0002] Minimal Quantity Lubrication technology, also known as MQL (Minimal Quantity Lubrication) technology, is to mix a very small amount of lubricating fluid with compressed air with a certain pressure and atomize it, spray it into the grinding area, and control the contact between the grinding wheel and the grinding debris, and the grinding wheel and the workpiece. effectively lubricate the surface. Under the premise of ensuring effective lubrication and cooling effect, this technology uses the minimum amount of grinding fluid (about a few thousandths of the amount used in traditional pouring lubrication methods) to reduce costs, environmental pollution and human damage. .

Problems solved by technology

[0009] However, this system is only used in the grinding process. The supply method of the minimum quantity lubrication cutting fluid is only external injection. The size of the electrostatic atomization nozzle is large and the precision is low, so it cannot be used for internal cooling turning.
