As we all know, titanium alloy material is a difficult-to-machine material. During the processing process, the cutting temperature is high, the tool wear is serious, the quality of the machined surface is difficult to guarantee, the cutting efficiency is low, and the manufacturing cost is high. Therefore, some researchers conducted
research on titanium alloy processing under low-temperature minimum quantity lubrication conditions, and summarized the tool life, cutting speed, and machined surface quality of the workpiece under
low-temperature minimum quantity lubrication conditions for titanium alloy processing. , workpiece deformation and other conditions are analyzed. Below we will briefly introduce the processing surface quality and workpiece deformation
, surface quality
The surface quality of the workpiece processing is related to many factors, such as the rigidity of the process system, The rigidity of the tool, the spindle runout, the tool runout, the toolholder runout and the overall runout after the tool is installed, the clamping stability of the workpiece, the feed per tooth, etc. Of course, the effect of lubrication and cooling also has an impact on the surface quality of the workpiece processed. During the actual processing of the workpiece, multiple cutting tools were observed. After comparative analysis, the surface quality of the workpiece cooled using low-temperature minimum quantity lubrication was better than that using cooling. The surface quality of workpieces processed by liquid processing should be significantly improved. However, there is no microscopic measurement of the machined surface of the workpiece, so there is no intuitive data comparison. However, the intuitive visual conclusion is that the surface quality of the workpiece used for low-temperature minimum quantity lubrication processing is good.
, Workpiece deformation
Under normal circumstances, workpieces will be deformed after processing. No matter which method is used for cooling and lubrication, the workpiece will be deformed to varying degrees. After comparative analysis, the use of coolant After the overall cutting of the workpiece is completed, the side bend of the straight edge of the workpiece is ~. However, for the workpiece processed using low-temperature minimum quantity lubrication, during the processing, the surface temperature of the workpiece is relatively low, and it basically feels It is not in a hot state. In addition, the side bending amount of the processed workpiece is ~, which is smaller than the deformation of the workpiece processed using coolant.
After analysis and comparison, it can be seen that in
the cutting state of low-temperature minimum quantity lubrication, the surface quality of the workpiece processed is better and the deformation is smaller.
