细长件导轨加工的工艺研究

Research on Thin and Long Guide Rail Machining Technology

2 m以上的单双面导轨均属于刚性较弱的长导轨零件。这些零件在加工中,由于其装夹力、切削力及自身重力的作用会产生较大变形。通过对细长导轨加工变形等问题的分析,从加工机床和工件定位出发,得出了保证加工精度的最佳方法,从而保证了细长导轨的加工质量。

The single and double-sided guide rails with a length of more than 2 m belong to long guide rail components with weak rigidity. In the machining process of these parts,they suffer serious deformation under the action of the clamping force,cutting force and self-gravity. Through analysis of the deformation of long and thin guide rail in the machining process,starting from the positioning of processing machine tools and workpieces,the best method for ensuring machining accuracy has been obtained,thereby guaranteeing the machining quality of long and thin guide rails.
