缸简是液压油缸的关键零件之一。我厂缸筒的长径比大、孔的精度(D_4以上)和光洁度(8以上)要求高。原先,分粗镗、细镗、精镗、滚压等四道工序进行加工。这种加工方法,辅助时间长、机动时间多,因而生产效率低。提高缸筒镗孔的生产效率是长期以来我厂液压车间的生产关键。为此,车间党支部组织了“三结合”攻关小组,在学习兄弟单位的先进经验的基础
Cylinder Jane is one of the key components of the hydraulic cylinder. I plant cylinder aspect ratio, hole accuracy (D_4 above) and finish (8 or more) demanding. The original, sub-rough boring, fine boring, fine boring, rolling and other four processes for processing. This processing method, auxiliary time, maneuver time, and thus low productivity. Improve the production efficiency of the cylinder bore is the key to the production of our hydraulic workshop for a long time. To this end, the workshop party branch organized “three combination” research team, based on advanced experience in learning brothers units
