4) one is often completed the process, Z value is adjusted into forward a screw pitch, and so on, until the eddy flow slot of setting item number
It completes the process.
Further, further include the installation steps of cutter before step 1): cutter head being mounted in tool apron, tool apron is mounted on
On knife bar.
Compared with prior art, the invention has the following beneficial technical effects: the present invention provides a kind of angle adjustable vehicle
Knife, tool apron are equipped with scale, and tool apron is rotatable to be located at knife bar, can easily centering be rotated by rotating a certain angle
Angle overcomes the problem big to knife difficulty.
The present invention provides a kind of method using angle adjustable lathe tool processing multistart worm shape eddy flow slot, the eddy flow slot of processing
Precision is high, and the processing quality of poppet worm screw shape eddy flow slot, simultaneous processing qualification rate and processing efficiency are improved, and ensure that boat
The safety and reliability of empty engine.
