When machining at the height of the collets, a
turning of the workpiece may be necessary.

In any case, the desired machining operations must be carried out.
according to the workpiece dimensions (especially for
minimum requirements), the materials used and

Workpiece reference system
The pre-positioning of the workpiece in longitudinal direction
(X-direction) takes place in the loading area on the left
machine side by a stop, which is located in a
is placed in a fixed position in the worktable. A
Laser photocell automatically reads the workpiece reference
in X (zero point); additionally, the same photocell reads
the real workpiece length, provided that this function is used in the machining
work program is activated. In the event that the
detected dimensions do not match those of the program
the machine does not perform any machining operations

Machine structure
Standardized and sandblasted steel structure with through-hole
standard machine stand, which is designed for the installation of
is machined from linear guides and carriages.
The design enables the construction of machining
units on the front of the stand.

Workpiece positioning unit
The workpiece positioning system in X direction is
by two collets, which hold the workpiece during
Keep the machining phase clamped. The movement takes place
by means of two independently driven servo motors.
The collets are equipped with a system for detecting the
thickness of the workpiece, which makes it possible to work in
real time to adjust the program value and the necessary
to ensure precision in the Z-direction during machining do.
Fully automatic opening and clamping during the
Processing phase for workpiece thicknesses between 8 - 60 mm.
(AXES X1-X2)

Workpiece contact surface
The workpiece contact surface on which the machining and
units, consists of a series of rubber-
of layered rollers, which determine the workpiece reference in
Form Z-direction. On the opposite side of the
processing unit, a back pressure system is installed,
which holds the workpiece optimally in the machine. The
Positioning takes place automatically via a brush-
loose motor depending on the workpiece thickness.
Working height of the workpiece support surface in the clamping
pliers: 900 mm (+/- 10 mm).

Safety devices
To ensure the safety of the operator
the machine is equipped with a protection system,
which allows access to the machining area. hindering.
The security system complies with the euro-
European machinery directive 2006/42/EC.
Control cabinet
The control cabinet of protection class IP54 is complete with
all power elements for the axis controls (basic
machine 5 axes).
The servo motors and the corresponding servo packs are
