Machine and material as well would help.Post your speeds and feeds
Hello , speeds are 1085 RPM feed at 4.0 IPM, material is 1018 , machine is MAZAK HCM HCN5000 smooth G controlMachine and material as well would help.
Hello thank you very much , the tap hole size I will check this the drill may be walking so that when the port cutter engages chatter is reduced , also yes I agree that lower RPM May remedy the situation while increasing the feedIs your pilot hole oversize? Those cutters are usually remarkably stable as long as the tap minor diameter is allowed to cut its own hole.
How are you holding the cutter? How well is it dialed in? What materal?
Slow the spindle to about 60 rpm and feed it hard, no dwell, and get out of the hole to salvage the chattered hole.
That is way to fast, try about 300 RPMHello , speeds are 1085 RPM feed at 4.0 IPM, material is 1018 , machine is MAZAK HCM HCN5000 smooth G control
I’m running these parts on two pallets on two tomb stones , on 8 vises per tomb stone,
Hello thank you for the insight , , I figured that for a carbide insert porting tool I needed higher RPM, HSS port cutters I usually run the speed within range of the RPM’s you mentioned,so in hindsight 868 rpm, followed by a 5 second dwell Carbide insert 7/16-20 porting tool is GOLDEN! BoooomThat is way to fast, try about 300 RPM
AGREED!Make sure you're holding it in the shortest length tool holder possible and the tool isn't sticking out more than needed. Rigidity at the tool makes a huge difference.
