Im making some hexagon nuts out of 310 stainless steel, the starting diameter is 35mm and my finished a/f im aiming to achieve is 30mm
Im using a Trishul 2ts polygon milling machine, ive set up the program to take 2 passes at 1.25mm each time and im using tnmg yg3030 inserts with a tool nose radius of 1.2 but burning through inserts really quickly.
My parameters are 0.04 feed rate and spindle speed of 140m/min
Can someone advise on better speeds or feeds or maybe some inserts #industry source
I am hoping that someone here might have some tips for me as far as my design for a face knurling project on something resembling a serrated face on a 2” washer
Currently using a rotating conical knurling tool that is pushed into face of material in a lathe
In metal forming there are old school techniques that defy logic.. For instance When burnishing we intentionally start with a rough surface and end with a mirror surface..??
It’s not logical.. but definitely factual
Maybe I missed something regarding forming serrations so that they are sharp at the crest
(Maybe a micro slot in tool instead of a 90deg V shape)
