MAS 403 BT | TOPRUN - PFS
The purpose of balancing a toolholder is to improve the distribution of the masses of its body so that it rotates without creating centrifugal forces above a prescribed limit.
The use of Toprun balanceable toolholders provides the following advantages:
- considerable extension of machining center spindle life;
- considerable extension of tool life;
- improved accuracy and surface finish;
- drastic reduction of vibration and noise level of the machining center.
For high speed machining with Toprun toolholders, the two counterweights in the graduated groove (patented) have to be positioned following the indications provided by the electronic balancing unit; a quick and easy balancing of the toolholder fitted with tie-rod and tool according to the ISO 1940/1 standard. For machining up to 8,000 rpm it is sufficient to position the counterweights at 0° and at 180°.
