I will soon have a number of BBT30 (dual contact) mill-turn machines, similar in form and function to a Mazak Integrex or DMG Mori CLX/CTX. They have 10kw, 24,000 RPM BBT30 spindles.
While I have used CAT40 dual contact and BT40 non-dual contact before on VMCs I owned in the past, I would like to know everyone's best practice tips for 30 taper machines, as well as specific tools and holder types that people have had good results with.
My biggest concern for any 30 taper machines is how to make features that require long tool gauge lengths, such as big and deep holes, very tall sidewalls, or deep pockets with small radii in the bottom. These are the types of parts and features that I struggled with in the past due to chatter, chip evacuation, tolerances, etc. I have seen some impressive demo cuts with Brother machines, and I want people who have experience doing heavy of difficult cuts with BT30/BBT30 machines to tell me how I can safely pull off these types of cuts without bustin pull studs and sending holders through the safety glass at 20k rpm.
