When using high-speed machining centers (8,000-10,000 RPM and higher), it is generally recommended to balance the tool and toolholder as an assembly. Despite the relatively small mass of this assembly compared to the spindle, at these higher speeds small amounts of unbalance create large amounts of centrifugal force. It's this force which creates vibration which in turn can damage the spindle and/or bearings and create other undesirable effects such as chatter, poor surface finish, high tool wear etc.

Why Balance Toolholders?

Vibration in a spindle can have devastating results on the performance and life of a machine tool. For this reason, all manufacturers of machining centers, milling machines, grinders and the like, take great care in accurately balancing their spindles. However, at high speeds (typically above 10,000 RPM), unbalance in the tool and toolholder can cause significant damage to the spindle bearings and to the spindles itself.

A Balanced Toolholder provides:

Better surface finish
Tighter tolerances
Increased tool life
Longer spindle and bearing life.

Resulting in:

Higher machine performance
Lower tooling cost
Greater profits
