摘　　要：在分析套类工件结构特点和技术要求基础上,以精度为目标,开展了立式复合磨削工艺路线设计及与之相适应的精密立式磨床研制。所研制的磨床其动态回转精度优于0.3μm的高刚度液体静压直驱式静压回转工作台和运动直线度优于0.2μm/200 mm的高刚度液体静压导轨很好地保证工件磨削圆度和母线直线度。研制的机床实现了内孔磨削圆度0.7μm,外圆磨削圆度优于0.45μm的磨削效果,能满足各种高精度主轴部件套类零件高精度磨削。A high-precision grinder is developed based on the characteristic analysis of structure and manufacture of sleeve parts as well as the design of vertical complex grinding process.This high-precision grinder could achieve good roundness and generatrix straightness due to its high stiff hydrostatic rotary table and guideway of which dynamic rotary accuracy and motion straightness are 0.3μm and 0.2μm/200 mm,respectively.As the measurement results shown,the roundness of the inner bore and the excircle are better than 0.7μm and 0.45μm respectively,which demonstrates that the grinder has the enough capability of high precision grinding for sleeve parts of the spindle.
