(Started at 0.050 per pass reduced the cut in deep slots)<br /><br />If the feed rate is too slow the stainless hardens. Must keep up the feed rate. The rates above are about 75% of what my references say they should be.<br /><br />I also drilled holes for the pocket starts so the end mill did not have to plunge into stainless. Where I could not pre drill I ramped the bit in at a shallow angle of 5 degrees.Paul Breedhttps://www.blogger.com/profile/11024641086551653462noreply@blogger.comtag:blogger.com,1999:blog-2236472828366913719.post-2950255861928249162009-09-01T12:47:46.502-07:002009-09-01T12:47:46.502-07:00o.O An 8 lb chunk...the pain...the pain...
Any a...o.O An 8 lb chunk...the pain...the pain...<br /><br />Any and all suggestions for dealing with stainless are welcome. And then some. We've picked up polycarbide end mills and whatnot, but ... evidence from someone that's further down the road is ALWAYS welcome.<br /><br />Thanx for the compliment.<br /><br />Lots of luck with your flights.Will Bairdhttps://www.blogger.com/profile/07562404098136557872noreply@blogger.comtag:blogger.com,1999:blog-2236472828366913719.post-85184721870739738032009-08-31T12:40:07.368-07:002009-08-31T12:40:07.368-07:00>Aluminum is your friend.
>Stainless steel ...>Aluminum is your friend. <br />>Stainless steel is your sadistic bully in grade school.<br /><br />I just spent the weekend machining a 1/2lb Stainless steel fuel injector and catalyst support plate out of an 8lb chunk of 316 stainless.
