薄壁衬套车削研究

薄壁衬套质量轻节省材料占用空间少,可提高机器的各项机械性能,被广泛地应用于不同行业。由于薄壁衬套刚性差,车削时,装夹困难,受夹紧力、切削力、切削热的影响容易产生变形,切削过程中容易产生振动。因此应在装夹方法、合理选择刀具几何角度和切削用量来减小切削力,选择正确的冷却方法和减少振动等方面考虑,保证薄壁衬套的加工精度。

The thin-walled bush light weight materials to save a small space can improve the mechanical properties of the machine are wide- ly used in different industries. As the thin-walled bushing stiffness is poor, turning when the fixture difficulties, by the clamping force, cutting force, cutting heat effects prone to deformation during the cutting process prone to vibration. Clamping method should therefore be reasonable choice of tool geometry and cutting parameters to reduce the cutting force, choosing the fight cooling methods and to reduce vibration and other considerations to ensure the processing precision of thin-walled bush.
