Optimum Opti mill MB 4P Betriebsanleitung Seite 69

the suitable speed is set depending on the diameter of the drill,

the pressure must only be such that the drill can cut without load

in case of too strong pressure the drill will get worn early or even might break resp. get

jammed in the hole. If the drill gets jammed immediately stop the main motor by pressing
the emergency stop button,
for hard materials, e.g. steel, use commercial cooling / lubricating agents,

generally always drive the turning spindle out of the workpiece.

ATTENTION!
Do not use the drill chuck for milling tools. Never clamp a milling cutter into a drill chuck. Use a
collet chuck and the corresponding collets for the end mill.
When milling make sure that
the corresponding cutting speed is selected,

for workpieces with normal strength values, e.g. steel 18-22 m/min,

for workpieces with high strength values 10-14 m/min,

the pressure is selected in a way that the cutting speed remains constant,

for hard materials commercial cooling / lubricating agents are used.

INFORMATION
The milling machine MB4PV with frequency converter for regulating the speed is built according
to the standard EN 61800-3 class C2.
WARNING!
The machine is not intended for use in residential buildings, in which the power supply
is provided via a public low voltage supply system. In these areas, it may be difficult to
guarantee electromagnetic compatibility due to conducted and emitted interference.
