7.5.1 Installation of the HSD 0804H0009 screw dowel in the
ISO30 DIN69871 cone
„
Thoroughly clean the pull stud and its housing in the ISO30 cone.
„
Spread high-strength thread locking compound LOCTITE 243 (or other equivalent product) on
the thread of the screw dowel.
„
Tighten the pull stud 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 243, or according to the manufacturer's instructions if an alternative equivalent
product is used).
The use of non-original HSD screw dowels, or their incorrect installation, may cause
the tool-holder cone to be suddenly ejected.
Pay attention to the dosage of the thread-locker liquid. Excessive quantities may
unintentionally obstruct holes and/or adversely affect the operation.
Always use an adequate quantity of thread locking compound and also pressurised
air to make sure that the excess material has been removed.
7.5.2 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 chapter 8 “Maintenance” ).
„ During machining operations, avoid all contact whatsoever between the non-cutting
rotating parts and the piece being machined.
„ The tool holder cone seating must always be protected against the entry of impurities:
use a suitable plug or a tool holder cone.
„ At the end of the working day, always remove the tool holder cone from the
electrospindle to avoid sticking. Close the tool holder housing using a clean tool holder
cone at ambient temperature.
„ Do not rotate the electrospindle without a tool holder inserted. In particular for HSK
models, rotating the electrospindle without a tool holder will upset the balance and
operation of the collet.
