5.5.4 Machine stop during machining
If the machine has been stopped during a machining cycle, the operator must remove the spindle from
the piece.
NOTE
Safety
warning
DANGER!
Danger of collision between the spindle and the piece.
5.6
Working procedures
The sections that follow describe the operator tasks required for correct machine operation.
We recommend the instruction manual be read and fully comprehended before machine use, especially
as regards operating procedures and safety regulations.
5.6.1 Operating modes
The machine may be run in four different modes.
HOLD-TO-RUN movement (portable control)
Machine movements controlled exclusively by skilled and authorized personnel using the portable control
located inside the safety enclosure.
SINGLE-STEP, loading/unloading (processing cycle)
Loading/unloading of the materials, with the operator standing in front of the machine, manually loading
and unloading the piece(s) on/from the support devices located on the table. Once the piece is placed, it
is locked by pressing the pedal button; then the loading operation is confirmed, and the machine brings
the piece in working position (inside the machine, in the machining heads area).
The closing of the clamps during the stage when the operator interacts with the support device, is
performed at reduced pressure. The pressure is then increased, after confirmation of the end of loading,
by pressing the specific button.
At the end of processing, the piece is automatically taken outside the machine and the operator manually
removes it from the support devices; then a new piece is loaded and another processing cycle is started.
TANDEM processing cycle
The processing occurs with the piece supported by both support devices (Y1 and Y2 axes) that move
synchronously. The tandem processing requires a machine setup operation by the maintenance
technician, who removes the central guard located between the two axes Y1 and Y2, and enables the
tandem processing in the software, which allows synchronous advancing of axes Y1 and Y2. At the end
of tandem processing, the maintenance technician must perform the setup for SINGLE-STEP,
loading/unloading processing. To do this, it is mandatory to reassemble the central guard and disable the
tandem processing in the software. The processing cycle occurs in the manner described in the
SINGLE-STEP, loading/unloading (processing cycle).
