Pm\plus are made by kennametal. about 1/2 the price of carbide and will run circles around anything that we found.
example in 304 ss 1/2 4 flute we run S860 F4.3 1/8 depth of cut. they even have some stub length avaible. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, March 04, 2004 11:38 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: RE: [mfg-smartcam] Hard Milling I never heard of pm/plus....can you give any other details on this product Thanks Jim -----Original Message----- From: Chris Hurst [mailto:[EMAIL PROTECTED] Sent: Thursday, March 04, 2004 11:09 AM To: [EMAIL PROTECTED] Subject: RE: [mfg-smartcam] Hard Milling Toss the carbide and tell him to invest in pm\plus end mill's.

He isn't used to the aggressive approach the shop takes when it comes to milling (time is money.) He asked me for some guidelines for milling hardened die steels like A2 or M2. The hardness is Rc 60-62. In my company we have always been on the conservative side with hard-milling. For uncoated carbide we always start at 50 sfm and take light cuts around .010 to .020 deep. Since his shop is much more aggressive than that, I am unable to give him anymore than that mentioned above. Can anyone share some good starting points for aggressive hard-milling with uncoated, coated, flat, bull, & ball nose carbide end mills? I am looking for recommendations for feeds, speeds, and depths of cut for various diameters. The application is mostly 2D work on tool & die components though there may be some 3D contouring also. I am not asking for any proprietary information, just some good starting points I can forward to my friend. Thanks in advance for any help you can provide.
