在设备维修中,我们常碰到一些不具备专业化生产条件下,加工难度大的零件的修复或重新制造。长油缸的深孔加工就是一例,当长径比L/D>5时,加工起来就十分困难:刀杆细长:强度和刚性就比较差,加工中容易引偏与振动、切屑不易排除,冷却条件差,刀具磨损快、易崩刀,孔的加工精度不易达到要求。装夹不好还容易变形。它要求工人技术水平高,加工工艺也较复杂,而加工质量很难得到保证,下面介绍一种长孔油缸的加工,供同行参考、借鉴与探讨。
In equipment maintenance, we often encounter some do not have the specialized conditions of production, the processing of parts of the repair or re-manufacturing. Long hole long cylinder processing is an example, when the aspect ratio L / D> 5, the processing is very difficult: Arbor slender: the strength and rigidity is relatively poor, easy to bias and vibration during processing, the chip is not easy to rule out, Poor cooling conditions, fast tool wear, easy to collapse knife, hole machining accuracy is not easy to meet the requirements. Poor clamping is also easy to deformation. It requires workers with high technical level, processing technology is also more complex, and the processing quality is difficult to be guaranteed, here is a long hole cylinder processing for peer reference, reference and discussion.
