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

Processing Method	Side Milling	Work Material	SUS304	Coolant	Water-Soluble

Example

● High efficiency machining can be realized by suppressing chattering through the use of "unequal lead."
● Smooth chip discharge is achieved using an optimum groove geometry.
[ ! ]The electrical conductivity is minimal.
