Features of VAC Unequal Leads

VAC Series Carbide 4-Flute Uneven Lead Square End Mill:Related Image

Unequal Leads + Unequal Division = Suppressed Chatter Vibration

Design with Features to Suppress Vibration
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

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.
