Deep hole drilling machine is a mechanical equipment specially used for drilling three coordinates. It has the characteristics of high efficiency, high precision and high automation. It uses the chip removal method to drill small holes. The deep hole drilling machine can achieve the processing effect that can be completed by ordinary machine tools such as drilling, expanding, and reaming. The precision of deep hole drilling machine is IT7-IT10, the surface roughness is RA3.1-0.04μm, and the straightness is less than or equal to 0.05mm per 100mm. Since deep hole drilling machines have so many processing advantages, what requirements do deep hole drilling machines require for cutting fluids?
First, it must have a good cooling effect. It is used to eliminate the heat generated by the deformation of the workpiece and the friction with the machine tool, and suppress the generation of chipping tumor.
Second, it has good high-temperature lubricity, which ensures that the tool can still maintain a good lubrication state under the high temperature of the cutting zone, and reduces the wear of the blade support.
Third, it has good permeability and chip evacuation, and good chip evacuation, ensuring the smooth discharge of cutting is the most basic and most important role of cutting fluid. The cutting fluid needs to have good permeability, so that the cutting fluid can penetrate the cutting edge in time to help the chip discharge.
