PCD刀具在航空液压壳体加工中的应用

Application of PCD Cutting Tool in Aviation Hydraulic Housing Machining

航空液压壳体类零件精密孔在加工过程中经常出现孔径尺寸不稳定、粗糙度无法保证等情况。结合实际加工情况,针对加工工艺和加工方法进行分析,找出超差原因,选用PCD刀具作为最终精加工刀具替代硬质合金刀具。以孔加工为例,详细介绍了PCD铰刀和PCD镗刀在航空液压壳体加工中的试验过程和实际应用。结果表明,PCD刀具相对于传统刀具在精加工铝合金方面的优势非常突出,有效地解决了孔加工效率低、质量难以控制的问题。

In the processing of aviation hydraulic housing parts, the aperture size is often unstable and the roughness cannot be guaranteed. By analyzing the actual processing technology and method, the reason of size variation is found and PCD cutting tool is selected as finishing tools to replace hard alloy cutting tool, Taking hole processing as an example, the test process and actual application of PCD reamer and PCD boring cutting tool in aviation hydraulic housing processing is intro- duced. The results indicate that the PCD cutting rods are outstanding in the finish machining of aluminium alloy compared with traditional cutting tool and can solve the problem of low machining efficiency and uncontrollable processing quality.
