Hey there guys. I usually turn 7075 aluminum ( stuff will make anyone feel like a rockstar) and 4140 PH for my job. I am running a Haas ST-15Y with collet chuck that provides me with a decently rigid setup. I am now working with some 17-4 in Condition A. I am looking for some advice from people who have turned it before. I use Sandvik OD and ID profiling tools a few, through tool coolant, I-dream Carbide drills and a Mitsubishi Indexable drill at .937 diameter. I make fairly small parts and I start with stock at a diameter of 1.75.
What kind of feeds and speeds do you guys run for this stuff? My insert recommends have been fairly useless so far. I have had some success running at an SFM of 800-900 and a feed anywhere from .008 to .011.
My self and a partner run a small start up business with just the two of us. We are trying to conserve money and with hat being said, I am here asking for some insight from fellow machinists. I am trying to achieve good tool life and decent finish. Mainly I am just trying to avoid the waste of inserts. I want to achieve good running numbers but do not have unlimited corporate funds to troubleshoot without some good research and advice. I am self taught in both programming and operating a cnc so you will have to forgive me if I am speaking with a lack of knowledge or nomenclature. Thanks guys
