M6025工具磨床砂轮主轴,原结构采用四件“36205”D级向心推力球轴承,分别装在两轴承座中,由于砂轮壳体同心度误差和轴承座同心度误差的积累,给滚动轴承装配同心度的提高带来极大困难。滚动轴承的装配工艺要求十分严格;在重负荷切削下,精度更难保持、寿命低、停修时间多,轴承更换量大,影响生产发展。为了提高产品质量,我们对M6025工具磨床进 M6025 tool grinding wheel spindle, the original structure of the four “36205” D-class radial ball bearings, were installed in the two bearing blocks, due to the concentricity of the grinding wheel housing and bearing concentricity error accumulation to the rolling bearing assembly concentric Increasing the degree of great difficulties. Rolling bearing assembly process requirements are very strict; under heavy load cutting, the accuracy is more difficult to maintain, low life, more repair time, bearing replacement, affecting the development of production. In order to improve product quality, we grind into the M6025 tool
