Abstract 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 introduced.
The results indicate that the PCD cutting tods 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.
