• Standard connection plate that can be assembled easily on most CNC spindle machines with a DIN2079 interface. This connection plate enables the use of ITS
BORE components with the MB connection by using any standard adapter with four screws. It is affixed directly on the machine spindle.

The balancing rings enable a high degree of balance. This is achieved by setting the two counterweights to balance the toolholder on which it is mounted.
The result is a more economical and accurate mounting technique.
The use of the balancing rings provides the following advantages:
• Improved accuracy and surface finish
• Considerable extension of tool life
• Considerable extension of spindle bearing life
• Drastic reduction of vibrations and noise
The purpose of balancing a toolholder is to improve the distribution of the masses of the different elements in order to produce centrifugal forces within a
prescribed limit, when spinning at a given spindle speed (RPM). The balancing operation for a toolholder has the aim of bringing the original unbalance within the
maximum admissible level “G” prescribed by the ISO 1940/1 standards.
