一、精密冷拔管对现有加工油缸缸筒工艺适应性问题。 由于精密冷拔管精度高,一般省去粗加工。以下所谈都是指精加工方面的问题。油缸缸筒内外壁光洁度要保证在V9以上。内壁精加工一般采用滚压和珩磨;外壁采用磨削。
First, the precision cold drawn tube cylinder process adaptability of the existing problems. Due to the precision of precision cold drawn tubes, the general need for roughing is eliminated. The following talk about the finishing problems. Cylinder cylinder outer wall finish to ensure that in the V9 above. The inner wall finishing generally use rolling and honing; outer wall with grinding.
