4.7.4 Selecting the speed
The correct speed is an important factor for milling. The speed determines the cutting speed by
which the cutting edges cut the material. The service life of the tool can be increased and the
working result optimized by selecting the correct cutting speed.
The ideal cutting speed basically depends on the workpiece and the tool material. Higher
speeds are possible with tools (mills) made from hard metal or cutting ceramics than with tools
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. These machining
technology reference table books should bridge the gap between the predominantly theory-
oriented textbooks and reference & reference table books mostly written with the few theoretical
principles in practice.
4.7.5 Gear stage

Changing the gear stage may only be at a standstill.
4.8 Direction of spindle rotation
A change in the direction of rotation at the MH50G is done by pressing the push button.
