Problems solved by technology

Among them, in the process of pouring cutting fluid, the amount of cutting fluid that can enter the cutting area and actually play a role in lubrication and cooling is very small, and the small part of cutting fluid that enters the cutting area will quickly vaporize into a "steam film" after being heated. The emergence of new cutting fluids will hinder the entry of new cutting fluids into high-temp

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] The method for lubricating and cooling the cutting process that the present invention adopts is; adding vegetable oil (such as rape oil, camellia oleifera oil or castor oil) or deionized water with a volume ratio of 1 to 5% and a particle diameter of 20-40 nanometers Nanoparticles (such as aluminum oxide Al 2 o 3 , multi-walled carbon nanotubes or zinc oxide ZnO), and then add a dispersant (such as sodium dodecylsulfonate SDBS, chemically pure, anionic; or hexadecyltrimethyl bromide) with a volume ratio of 0.05 to 0.15%. Ammonium chloride CTAB, chemically pure, cationic) and ultrasonic vibration with a frequency of 10-40KHz to obtain a uniform and well-dispersed oil-based (or water-based) nanoparticle suspension, compressed at a pressure of 0.3-1MPa Under the action of air, the nano-particle suspension is fully atomized into mist parti...

Abstract

The invention discloses a lubricating and cooling method for cutting process and a device thereof. The method comprises the following steps: adding nano-particles with particle size of 20-40 nm at a volume ratio of 1-5% into vegetable oil or deionized water; adding dispersant at a volume ratio of 0.05-0.15% while conducting ultrasonic vibration at a frequency of 10-40 kHz so as to obtain uniform oil-based or water-based nano-particle suspension with high dispersibility; and under the effect of compressed air with pressure of 0.3-1 MPa, sufficiently atomizing the nano-particle suspension into atomized particles with micron-level diameter, wherein the high-pressure atomized particles break through a cutter through a nozzle and an air barrier layer on the workpiece surface and then are ejected to a cutting area so as to lubricate and cool the cutting area. Through the lubricating and cooling method for cutting process and the device thereof which are disclosed by the invention, the cooling medium with high lubricating performance and heat conducting performance can be effectively injected into the cutting area so as to improve the lubricating state of the cutting area and reduce friction and heat emission; and the generated heat is taking away in real time.

Description

technical field [0001] The invention relates to a method for lubricating and cooling cutting operations, and also to a device for implementing the method. Background technique [0002] During the cutting process, especially for high-hard and difficult-to-machine materials, a large amount of heat will be generated in the processing area. In order to avoid thermal damage to the workpiece, the processing area must be lubricated and cooled to reduce heat generation, and the generated heat will be taken away in time. Walk. At present, the methods for lubricating and cooling the processing area mainly include: pouring cutting fluid method, water vapor cooling method, liquid nitrogen cooling method, low-temperature cold air cooling method and minimal quantity lubrication (MQL) technology. Among them, in the process of pouring cutting fluid, the amount of cutting fluid that can enter the cutting area and actually play a role in lubrication and cooling is very small, and the small p...
