Features of VAC Unequal Leads
Unequal Leads + Unequal Division = Suppressed Chatter Vibration!
Design with Features to Suppress Vibration with Readily Vibrating Objects
Clean surface finish of machined objects!
- [ What are unequal leads? ]
- By changing the twist angles of each cutting edge of the same end mill, attenuation of generated vibrations is encouraged which leads to suppressed chatter.
- [ What are unequal divisions? ]
- The periodicity of the tool vibrations when cutting are cancelled by making the divisions at the bottom of the blade unequal
