made from high-alloy high speed steel (HSS). You will achieve the ideal cutting speed by
selecting the correct rotation speed by hand.
We recommend using a machining technology paperback
ISBN 978-3-8085-1473-3 (example, only in German language available). In these reference
table books you will find all the necessary and additional information. Those machining technol-
ogy paperbacks should bridge the gap between the predominantly theory-oriented textbooks
and the with mostly low theoretical foundations written practice books and reference books.
4.5.2
Gear selector switch
The speed is selected by means of the gear selector switches. You obtain a total of 12 speed
ranges in connection with the turning direction switch.
INFORMATION
Observe the speed table on the milling drilling head when selecting the range of speed.
ATTENTION!
Wait until the spindle has come to a complete halt before changing the speed with the
gear selector switch.
A change of the gear ratio during operation can lead to the destruction of the gearbox.
