Machining examples

 

 

 

 

 

FLEXI 7P-5AX
 5/6 AXES
Vertical Machining Centre
with two tables to be used in
   
DUAL MODE 
(SHUTTLE or TANDEM)

Fast - Versatile 
 Precise - Powerful

Conceived to boost productivity in multi-axes machining of small and large series in general machining and  mould making industry 

STANDARD SHUTTLE MODE 
 
A rotary table and a standard worktable take turns in the working area
TANDEM MODE 
 
This solution allows to manage large and heavy workpiece
 OPTIONAL TANDEM MODE 
 
The machine can be equipped with two rotary tables (6 axes) or with two standard worktables (4 axes) according to workpiece tipology to be machined

X-axis rapid and working traverse, both in shuttle and tandem mode, is controlled by a ball screw 

 

 

 
 
Load/unload station protected from the work area and ergonomically designed to assure optimal operator's comfort

SEVERAL WORKTABLE CONFIGURATIONS

5 AXES 
 
with long table (mm 1400/2300) plus rotary table at one end

FLEXI 7-4AX 
 four axes

 with 2300 mm worktable

THE MODULAR DESIGN OFFERS A WIDE RANGE OF VARIATIONS THUS ALLOWING  TO IDENTIFY THE MOST SUITABLE CONFIGURATION FOR ANY TIPOLOGY OF COMPONENTS

Detail of the tilting head 
The swivelling axis
is operated by two aligned torque-motors assuring extreme power and a remarkable torque for continuous service machining 

 
Extremely fast tool changer with a dual-gripper changing arm controlled by a totally mechanical system. If heavy tools are used, it is possible to program slower movements

 

Motorspindle angular positioning,  with one thousands of a degree resolution, is assured, from time to time, by a powerful hydraulic brake.
 The distance between spindle center line in horizontal position and table surface is as short as possible.
The motorspindle can work tilted by 20 degrees in undercut

  The motorspindle is a syncronous type, therefore its tool holder shaft undergoes a smaller elongation due to heating

The machine has been designed to allow excellent swarf removal from the cutting area. The swarf is carried out by two screw conveyors directly to the swarf conveyor placed on the left side of the machine. The angled surfaces of the telescopic guarding allow the swarf to fall freely, thus preventing the build-up of swarf.
Even in the case of dry cutting, swarf is removed and carried to the swarf conveyor.

 

 Laser beam system for tool offset control
  • Length and radius measuring at any spindle speed
  • Check of each cutting edge of the tool 
  • Detection of tool break even during rapid movements
  • Check of tool edge profile

 

 

 

  Sigma Tool check 
 
Tool magazine control panel. Tool data available close to the load/unload station:

  • Direct call of tools to be inspected or unloaded

  • Call of the tool magazine stations 

  • Display/input of H and R tool offsets

  • Tool coding

  • Managing of big tools requiring a free adjacent place 

  • Confirmation of the executed tool replacement
