Abstract
Description
technical field
[0001] The invention relates to the improvement of the metal cutting fluid, especially the cooling system used for the honing of the inner hole of the cylinder liner and the high-speed cutting processing of the machining center and the numerical control machine tool. Background technique
[0002] In order to meet the high-speed movement of the piston and piston ring and the requirement of no oil leakage, the inner hole of the cylinder liner needs a high degree of smoothness, and its honing needs to be ground with a very fine-grained (eg 180-240 mesh) emery strip. However, the boron alloy micropowder produced by the fine-grained sand bar in the process of honing the cylinder wall can easily enter the micropores of the sand bar and cause blockage of the micropores of the sand bar, which affects the normal and effective honing. In order to clean and remove the metal powder blocked in the micropores of the sand bar during grinding, coal and diesel oil with low su...
