Dynamic balancing of Flange set

By Gideon Levinson, Senior Dicing Blades R&D Specialist


Any round object that rotates at any given speed per minute causes some vibrations due to asymmetric mass distribution. At higher speed, the vibration phenomenon is being accelerated.  

The vibration issue is very critical on a dicing system, as parts are rotating at relatively high speed.

The main reason for vibrations on a dicing system is multiple parts assembled together on the spindle, such as:

  • The spindle itself
  • The wheel mount
  • Flange assembly with blade.

Although the spindle and wheel mount are balanced, the flange & blade assembly are the main reason for more vibrations. In most applications the existing vibrations of the flange & blade assembly can be tolerated without any balancing requirements.

However, some delicate applications require an extra dynamical balancing to achieve better cut quality.

Following are some applications requiring perfect balancing to achieve better cut quality requirements:

  • Ultrasound sensors dicing PZT for the medical industry
  • Magnetic heads for the storage industry.

Principle of Dynamic Balancing on Dicing Saws

Balancing a flange / blade assembly needs to be performed on the saw. A balanced flange out of the saw may help but is not a perfect solution as the flange and the blade can be mounted in different orientation and will result in different unbalanced characteristics.

Balancing the flange set on the saw is actually called dynamical balancing.

This is a well-known process and a common practice on balancing, for example, car wheels.
