Influence of Machine tool Spindle Balance on the Prediction of Surface Roughness in High-Frequency Micro-Forging Machining
In order to improve the machining accuracy of CNC machine tools,based on the spindle vibration information on the surface corrugation degree of machined parts,and carry out the spindle system balance analysis in the axial direction.Select a large vertical machine plane high-frequency micro-forging test to carry out surface roughness experimental testing.The research results show that after gradually increasing the spindle speed,a higher frequency spindle rotation state is obtained,and the roughness length is significantly shortened,reaching a fitting error within 0.005 μ m.According to the sensitivity of the calculation of surface morphology changes caused by different factors,the radial bearing position plays an important influence on the surface roughness.The study is a good guide to improve the quality of machining indicated by drilling on CNC machine tools.
