
The geometry of the taper must comply with standard DIN69871 for ISO30 cones and
standard DIN69893 for HSK cones.

The ISO30 tool holder cone must have a degree of accuracy AT3.

Avoid the presence of inserts, slots or other forms that could disturb the dynamic balance of
the tool holder.

At the maximum rated speed of the electrospindle, the dynamic balance quality grade must be
G = 2.5 or better (standard ISO1940).

The balancing is carried out with the tool holder assembled (cone, spring collet, ring nut, tool).

The screw dowel (also called the tang) of the ISO30 cone must be exclusively that supplied by
manufacturer (part number 0804H0009).
6.5.2 Installation of the screw dowel in the cone ISO30
DIN69871
• Thoroughly clean the screw dowel and its housing in the ISO30 cone.
• Spread high-strength thread locking compound LOCTITE 2701 (or other equivalent product)
on the thread of the screw dowel.
• Tighten the screw dowel to the cone with a torque of 62 Nm.
• Leave the cone to rest to allow the thread-locking compound to set (12 hours in the case of
LOCTITE 270, or according to the manufacturer's instructions if an alternative equivalent
product is used).
6.5.3 General recommendations regarding tool holder cones

The choice of tool holder is a determining factor as regards safety;

The tapered surfaces of the tool holder and its housing on the spindle-shaft must be
kept extremely clean to allow safe coupling (see section
7 “Programmed
maintenance” );
The use of non-original manufacturer-provided screw dowels or an incorrect
installation can lead to protrusion of the tool holder cone.
It is forbidden to use ISO or HSK tool holders that do not comply with the above
conditions. Non compliance with these instructions can lead to a risk of
breakage or an imperfect coupling of the tool holder cone, with the resulting
risks for the user.
