立式数控车床CK5225高精度主轴装配工艺设计

Design of High Precision Spindle Assembly Process for Vertical CNC Lathe

立式数控车床高精度主轴的装配精度直接影响工作台的精度,从而影响零件的加工质量,所以装配调整主轴的精度至关重要。CK5225系列机床凭借精度高、高速运动平稳、加工零件精度高,得到越来越多用户的青睐。该机床最关键参数是主轴精度高,机床的主轴径向跳动和端面跳动都严格控制在0.005 mm内。通过设计装配工艺、改进装配方法、制造专用工具,保证了精度要求。

The assembly accuracy of the high precision spindle of vertical CNC lathe directly influences table accuracy, so as to affect parts quality. So adjusting accuracy of spindle is very important. CK5225 series machine tool has high precision, good high-speed stability, high machining precision, getting more and more users favor. One of the most critical parameters of the machine is the high accuracy of the spindle, which radial and end face beatings are strictly controlled in the range of 0. 005 mm. Through designing assembly process, improving assembly method and manufacturing special tools, the accuracy requirements are guaranteed.
