Hello everyone,
I have been trying to thread a 1/2-20 thread on our Mazak QTU 250.The material is aluminum and the tool I have been using is below:
266RG-16VM01C001M 1125
There are two major issues with my finished thread:
1: There are burrs all over the threads
2: the finished thread will not thread into the female thread. It might go in half a turn or so and stop. It looks slightly skewed when inside half turn. My "thread identifier" on the other hand goes in goes on without a problem, so I'm assuming my threading is the problem.
I've had the basic Mazak training which set me up good enough to do the basics. Threading is not given much time at all during that training and I don't have anyone here with a machining background to point me in the right direction so please help. Feel free to be as blunt as necessary, you wont hurt my feelings. I just gotta figure this out.
The photos below show my program and the thread.
