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.
