4 Safety notice
4.1 General
These assembly instructions contain basic instructions to follow during incorporation, starting and
maintenance. It is therefore essential to follow the detailed instructions in this chapter, but also the
special measures and recommendations which are given.
4.2 Appropriate field of application
The electric spindle is manufactured according to the most advanced technology and its use offers
total safety. It can, however, cause danger if it is not used in conformity with the precautions for use. It
has been constructed for high frequency machining in materials such as aluminium, cast iron, steel,
brass, titanium, synthetic materials, composite materials, graphite and wood. The following indications
for machining with high speed of rotation must absolutely be respected.
!
ATTENTION!
To attain a long service life of the spindle the following indications must be
observed and respected. Non-compliance will shorten the service life of the spindle.
Basic indications
-
Take into account the dynamic balancing of the cutting tools.
-
Take into account the 0.01 mm maximum eccentricity, measured at the end of the tool.
-
Assure a minimum resonance frequency for each tool by optimising the machining processes.
-
Use cutting tools specifically designed for high speed machining.
-
Use the shortest cutting tools possible.
-
Make certain that the tools are well secured in the clamp.
-
Make certain that the kind of tool holder corresponds to the spindle.
-
Take into consideration the machining parameters for high speed machining, i.e. low-level
pass, rapid traverse and angling in two simultaneous axes.
-
The permissible operating temperature is between 5°C and 40°C.
Any other use, as well as uses extending outside the cited cases is not authorised. MEYRAT SA
declines all responsibility for damages caused in these cases. The user alone takes responsibility for
the risk.
