My time killer is deburring and I'm trying to cut that down as much as possible. most of out parts have .005 max edge breaks and are aluminum. we can run 45 degree chamfer mills on most of the features. the problem we have is where we have 2-5 ops and there are cut outs from previous ops. what are some options for slots like this?
we been using a small burr tool but its really not small enough to get the inside edge from the outside it works though and there is no room to go from the indside. I just dont want to do 1500-2000 slots every time we get a job like this, it cuts out on me running machines. lots of jobs have slots and holes though the sidewalls with 4-40 sti threads. then we mill the side walls which pushes the burr back in the hole. or slot.
On the 4-40 sti threads I found a 3/16 round burr bit works very well both in the machine and by hand. ( we have no room to get a chamfer tool in there) with the ball your able to hold it at almost angle angle to deburr the back side effectively.
any ideas?
we also tumble all our parts, but the media doesnt touch the slots do to fins close by and on the threaded holes it just pushes a burr back in.
