D’Andrea, headquartered in Lainate, Italy, is a world leader in the manufacture of high precision machine tool accessories. Known worldwide for the quality of its products, D’Andrea has been developing increasingly effective technologies since 1951, keeping pace with the modern demands of the precision engineering industry.

D’Andrea – Toprun, as balanceable toolholder, offers various 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 D’Andrea - 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 complete 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°. The patented D’Andrea - Toprun balancing system allows a quick, easy, accurate and inexpensive achievement of high balancing standards of the toolholder, within 0.5 g•mm/kg, without any need to remove or add material. Specifically, the original unbalance “U” of the tool and toolholder is neutralized by the resulting centrifugal force “C” produced by the two balancing counterweights “T1” and “T2” of the counterweights. The advantage of this system is that the operator just needs to position the counterweights without having to make any calculations.
