REMOVABLE GUARD
ccess door fitted with interlocking device and
guard block.
Each access door is fitted with an
interlocking device and guard block. During
regular machine operation, the door is closed
and blocked. To access inside the enclosure,
stop the machine and wait for the lock to
release. In case of power shortage, the door
remain blocked. In this case, the doors may
be unlocked mechanically using the specific
wrench installed near the interlocking device.
M06
COMBINATION OF REMOVABLE GUARDS
system that provides access to the piece
loading area, made up of an assembly of
removable guards.
n example application is a single guard that
stops all dangerous movements of the
machine, when it is opened. Only when the
guard is closed, the machine can perform the
operating cycles (for use in single-table
machines with Y axis or X-Y axes).
further example application is a protection
made up of 4 guards named A, B, C, D (for
use in machines with Y1-Y2 axes table). The
opening/closing pattern is such that the
coordinated opening/closing of the guards
allows access to loading/unloading areas, in
which dangerous movements are safely
blocked, but does not allow access to other
areas where the operating cycle continues to
be performed.
n example of such operating
pattern is the following:
LOADING:
(C)… OPEN / (A)…CLOSED
(D)… OPEN / (B)…CLOSED
UNLOADING:
(B)… OPEN / (D)…CLOSED
(A)… OPEN / (C)…CLOSED
Note: Each guard is fitted with an interlocking
device and guard block.
The doors and/or movable guards have the
purpose of protecting the operator against
the movement of the machining head, during
the loading/unloading of the pieces.
NOTE: In case of guards for machines with
Y1-Y2 axes table, the ejection of tool
fragments is reduced to a minimum, at least
along the direction of two horizontal axes
(ref. EN 848-3:2007+A2:2009, section
5.3.7.1.2.3.1).

M08
FIXED GUARD
Guards positioned to protect internal machine
organs.
The guards are fitted on the internal machine
parts inside the all-around enclosure and
protect operators carrying out controlled
movement of the axes while standing inside
the all-around enclosure.
