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,
if there is too much pressure, the drill will wear quickly and may even break or jam in the
borehole. If the drill jams, immediately stop the main motor by pressing the emergency stop
button,
for hard materials, e.g. steel, use commercial cooling / lubricating agents,
generally always back the spindle out of the workpiece while it is still turning.
ATTENTION!
Do not use the drill chuck as a milling tool. Never clamp a milling cutter into a drill chuck. Use a
collet chuck and the corresponding collets for end mills (or shank cutters).
When milling make sure that
the appropriate 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, use commercial cooling / lubricating agents.
INFORMATION
The milling machine MH25SV is built according to the standard EN 61800-3 EMC class C2.
WARNING!
This 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 possibly be
difficult to guarantee electromagnetic compatibility due to lead bound as well as emitted
interferences.
Overview of the EMC categories:
Categorie C1
required limit values Class B Group 1 according to EN 55011
Categorie C2
Required limit values class A Group 1 according to EN 55011, Installation by EMC experts
and warning: "This is a product of category C2 according to EN 61800-3. This product may
cause radio interference in a residential area. In this case, it may be necessary for the ope-
rator to take appropriate action."
Categorie C3
Required limit values class A group 2 according to EN 55011, whereby these limit values
