Breton Shapemill - the perfec 5 axes stone working centre for marble, granite and engineered stone

Breton Shapemill - CNC milling centre with 5 interpolated axes designed for cutting, contouring and turning operations.

Breton Shapemill is   a   CNC   milling   centre   designed   for contouring, cutting and turning with five interpolated axes.

 •  “rapid” displacements ofF up to 40 metres per and  a  fixed  work-table  offering  users  the  possibility  of multiple and complex machining operations which would otherwise require several  machines:
•  shaping of blocks or billets utilising a saw blade to obtain large size workpieces with complex shape.
• shaping  and creating recesses utilising milling tools.
• contouring utilising shaped tools.
•  cutting slabs and billets into workpieces utilising a saw blade.
•  turning of columns with shaped profiles or machining of columns to create a twisted effect all along the surface.

Shapemill stands out for performance
• “rapid” displacements of up to 40 metres per minute;
• giant work-table sizing up to 4.000x3.500 mm
• powerful high-frequency spindle  of 36 kW;
• max.  diameter of the cutting  saw  blade: 1.000  mm;
• “C” axis rotation: ± 200°;
• “A” axis rotation:  from 0° to +115°;
• “X” axis travel: 137.8  / 157.5  in;
• “Y” axis travel: 110.3  / 216.5  in;
• “Z” axis travel: 47.2 / 63 in;
• possibility of using  various saw blades, shaped tools,  drills, millers, etc.;
• automatic tool-store with 27 positions + (optional) 2 positions for the saw  blade.

Shapemill stands out for its structural features:
•  Steel work-table secured to the ground, with aluminium top  with  recesses  for  mounting  fixtures  to  secure  the work piece  in place.

• Beam with “gantry” movement  along  the  shoulders (“X” axis) on ground  guides and roller sliding block assemblies; the drive assembly consists of a pinion-and- rack system with  rack precision  to  hundredths, with  6 DIN 3961  Alpha  quality  grade,  and  precision  reduction gears   with   Alpha   backlash   adjustment system;  the motorization is by Siemens digital brushless-type motors.

• Spindle carriage manufactured from  iron casting  and moving on roller sliding block assemblies ( “Y” axis); the drive assembly consists of a precision  pinion-and-rack system powered by a digital brushless-type motor.  The spindle steel cylinder (“Z” axis) is positioned vertically on the  inside  of the  carriage and is moved by a ball bearing screw / preloaded lead nuts / digital brushless-type motor system. Provided with a pneumatic balancing system.

• Birotary head for interpolated 5-axis machining. The  head has   a  symmetrical  structure  and  consists  of  two   main structural   elements,  the   first  (“C”  axis)  is  fitted   with   a Schleifring slip ring system for ± 200° rotation around its own vertical axis and the second element (“A” axis) rotating from 0° to +110° and housing the high-frequency spindle. Rotation transmission are provided  by brushless-type motors.

• 6-pole 36 kW high-frequency spindle, cooled  by a closed circuit electric-cooling  system, which  has a rotational speed of up to 6.000  rpm and a steep torque  curve so as to supply the  maximum power  even when rotating  slowly  (e.g.  with a 39.4  in ø saw  blade at 1.000  rpm, the  maximum power  is supplied). The high-frequency spindle is fitted with a HSK-B80 conical  coupling  for  the  milling  tools  and  saw   blade  and provided  with  an internal and external  tool cooling  system. 
N.B. saw  blades  with diameters of 31.5 in and over must be secured to the spindle manually with a flange.

• Linear tool magazine with 27 cells.

• Store  for  saw   blade  with   a  max. diameter  of  23.6   in, secured to the side shoulders, for 2 positions as a maximum (optional accessory).

• Lathe for  producing  columns  and  twisted  effect  details with workable  sizes:  ø 42.5/63 x 126 in (optional accessory).

• Frontal protection barrier consisting of a series of sliding doors with manual opening;  doors are made from structure and are provided  with  wide  inspection ports.  The rear part of the milling centre is closed by a set  of steel plate panels.

• Siemens Sinumerik 840D SL:  the   latest    digitally-controlled computer numerical control system, with PC architecture and a PC unit utilising Windows as operating  system, with  Windows user- friendly  interface and fully-developed software for work  program management.

• Control  console  mounted  on   a   mobile    pendant structure and equipped with a 15-inch touch-screen colour monitor,  a joystick  to easily move the motorized working   axes   movement  and  a  USB   port  for  data transfer.

• Portable  mini  console,  wired   to   the   main   control console,  to  duplicate   the   major  controls   (axes management + hand-wheel, emergency shut-down, etc.); this  portable  mini console allows  the  operator  to be  close  to  the  piece  to  be  machined thus  controlling directly some delicate  machining  operations.

• Electrics and  utilities  are  housed  in  two   cabinets with IP54 grade of protection and cooled  by an air conditioning unit specially designed for a maximum external  temperature of +45°C.

• Superior quality components:

• racks  with precision  up to hundredths and  6 DIN  3961 Alpha quality grade
• precision reduction gears with Alpha backlash adjustment system
• Siemens digital  brushless-type motors
• Siemens CNC unit

Shapemill Teleservice

An Internet connection is required in order to ensure an effective technical  support in case  of need.

Software for simulating work cycles

This software allows  to simulate “Shapemill” when working  by dividing the  machining  centre into different parts: machine structure, axes, spindle,  tool-magazine, tools. The software imports the file generated by the CAM program (ISO code)  for the  piece  to  be  machined and  simulates the  entire  machining  cycle,  thus  detecting any  possible impact  which  may occur.

BretonSmartCam software for 3D programming

BretonSmartCam  software is a CAD/CAM  integrated environment enabling  to  create  complex surfaces which can   be   subsequently   machined  (using   the   integrated CAM)  by  numerical   control  milling  and  cutting   centres with   5  interpolated axes.  This   software,  with   a  user- friendly interface, runs on Windows.

• Automatic tool control (optional accessory).

It consists of a laser system for measurement  to   hundredths  of   the tool  profile  (installed  on  a shoulder of the machine) and of a software that automatically aligns  the  profiles  of  the series of tools that polish the edge. 
This software can also check the consumption and efficiency of each tool.

• Suction cups with mechanical locking H=9 in. (optional accessory).

The 5-axis machining center Breton ContourFive while working on the President Lincoln’s head

Hello everyone,
today, I’ll keep talking about my favorite subject, I want to talk about the Glorious President Abraham Lincoln’s head  in the White House Oval Office in Washington.

The 5-axis machining center Breton ContourFive NC 700 recently installed for our Customer Marble Fox - 1315 Armstrong Ave, San Francisco, CA 94124 – made the President Lincoln’s head in Limestone.

Just below you’ll find a short video showing the 5-axis machining center Breton ContourFive NC 700 with 5 interpolated axes while making the head.

What can I say?
The 5-axis machining center Contourfive NC 700 for marble, granite, natural and composite stone  thanks to its vertical travel of 700mm, it is the ideal machine for architectural and funerary art as well as for those processing which require a deep dishing out; it therefore offers the users the possibility of performing different and complex machining operations which would otherwise require several machines:
- shaping utilising the disc to get large and medium pieces with complex shape.
- shaping and dishing out utilising millers.
- contouring utilising shaping tools.
- sawing utilising the disc in general
- turning of columns with shaped profiles or machining of columns to create a twisted effect all along the surface.
Please keep in mind that in addition to ContourFive NC 700, Breton provides the following machining centers:
- ContourFive NC700 HD with disc with diameter up to 800mm,  
- ContourFive NC 1000 with vertical travel of 1.000 mm, 
- ContourFive NC 1000 HD with vertical travel of 1.000 mm and disc with diameter up to 800mm.
