Background
On one hand, MQL reduces the consumption of the cutting fluid to a trace degree, not only obviously reduces the use cost of the cutting fluid, but also reduces the harm of the cutting fluid to the environment and human bodies to the utmost extent by using synthetic esters with high natural degradability as the lubricating agent; on the other hand, compared with dry cutting, the MQL introduces a cooling and lubricating medium, so that the cooling and lubricating conditions in the cutting process are greatly improved, the abrasion among the cutter, the workpiece and the chips is remarkably reduced, and the reduction of cutting force, cutting temperature and the abrasion of the cutter is facilitated.
The conventional trace amount of lubricating oil has a poor lubricating effect and is liable to cause wear of the cutting tool, and the conventional trace amount of lubricating oil supply device is insufficient, and the trace amount of lubricating oil supplied to the bearing is extremely small, so that if the trace amount of lubricating oil is small in consistency and relatively hard, it is extremely difficult to stably supply a predetermined amount of the trace amount of lubricating oil due to the piping resistance in cases where the piping path is long, or where there are many places where the piping path is bent or bent at right angles in the middle.
