2.5 Types of a ground material
As shown on the graphs [Drawing 4] magnetic clamping force of the electromagnetic
base to the ferromagnetic ground depends on its magnetic properties. Steel with increased
carbon content and some other alloying ingredients has lower magnetic permeability, what
causes a decrease in the clamping force. Also a thickness of a work piece, on which the drill
is placed, is significant.
Maximum clamping force of the electromagnetic base to a 5 mm thick work piece
surface is only about 25% of a clamping force obtained from a smooth, plane, 22 mm
thick standard plate.
If such thin ground material does not bow, one can try to carry out drilling of a
hole, although with keeping the strictest precautions. Particularly a magnitude of a
pushing force on a feed handle should be very limited.
Appropriate rpm should be adjusted depending on if drilling would be carried out with
a drill bit, or with trepan type metal cutter and a metal cutter’s diameter. A drive is equipped
in mechanical 4-step reducing gearbox. A general dependence between drilling diameter and
drilling speed is shown in graphs [drawing 5], detailed guide is supplied by manufacturer of
used drilling tools. The graph is just a general guide and the shown dependence applies to
average structural steel.
Cooling agent is fed gravitationally from a coolant bottle through an arbor to an inside
of the metal cutter. For on-a-wall and on-a-ceiling positions special cooling pastes have to be
used.
2.6 Electromagnetic base clamping force control system
This system for security reasons is an integral part of each drill type PRO. It works by
constant monitoring of the electromagnetic force base adhesion value to the substrate. In the
case of fall the force value below to guarantee safe operation of the machine, the system
automatically switches off the drive drill. It also does not allow to enable drive which does not
guarantee the proper clamping force.
Clamping force depends on: type and thickness of substrate, thick coatings on the
substrate, rust or other contaminants, lack of flatness of the substrate, excessive roughness
of the surface,
excessive wear of the lower part of the electromagnetic base.
If there’s a problem to enable drive after turn on of the electromagnetic base so drive
works only after START button is pressed, and after release the drive is off - it means that
system works properly. The system didn’t allow to for further work due to insufficient
clamping force drills.
