A new benchmark in wire EDM performance.

GF Machining Solutions’ latest AgieCharmilles Cut P Series of wire EDM machines provides users with precise positioning and contouring capabilities that ensures high part quality and unrivalled productivity.


The Cut P 350/550/800/1250 machines are equipped with efficient power generators and feature robust design and build, intuitive human-machine-interfaces (HMIs) as well as several automation options for lights-out/unattended operations.


With Intelligent Power Generator (IPG) digital technology, the EDM machines deliver ultra-fine surface finishes (Ra 0.10 µm) and can improve cutting speeds by up to 20 per cent.


EXPERT Systems


Several Expert systems further optimise the IPG’s cutting performance, especially when undertaking demanding and challenging applications.


POWER-Expert monitors and changes the power levels required to machine parts with variable heights. The system protects the parts from unstable conditions while the machine maintains high cutting speeds. Simultaneously, this system controls the spark parameters during finishing operations to provide high-quality surface finishes on variable-height parts.


This maximises part finishes and significantly reduces the need for secondary benchwork.


Regardless of workpiece height, WIRE-Expert dynamically controls wire wear to achieve continuous geometrical accuracy from all directions.


For part profile accuracy, PROFIL-Expert automatically adapts the machining parameters and the cutting path for rough and skim passes to provide excellent control of fine details and to ensure positioning and contour accuracies of ±2 µm, while TAPER-Expert technology cuts angles from 0 to 30 degrees (45 degrees as an option) to maximum Z heights.


TAPER-Expert corrects shifts of the Z reference position in real time, even when the taper angle is changing. The taper angle is also held to within 10 seconds on average, providing taper accuracy and geometry reference accuracy throughout the taper cut.


Fixed tables on the machines provide rigidity and stability that ensure accuracy when machining heavy workpieces. Integrated temperature regulation systems consistently maintain temperatures within ±0.2 degrees Centigrade, which guarantees repeatability over long periods of time. However, in shops where the ambient temperature may vary throughout the day, a thermo-stability option provides an extra layer of temperature control protection from thermal effects on the machines’ axes.


The CUT P machines also feature GF Machining Solutions’ collision protection technology in the X, Y, U, V and Z axes that prevents potential machine damage and eliminates costly down time and maintenance, even at maximum axis travel speeds of 3 m/min.


Human-Machine-Interface (HMI)


The Windows 7-based AC Cut HMI 2 user interface on the machines simplifies file management and maximises operator efficiency with its 19 in. touch screen and latest i7 CPU technology.


This system also supports intuitive programming directly on the control as well as imported CAD/CAM files with built-in AC CAM Easy CAD/CAM software. The EDM series is also ready for the Internet of Things/Industry 4.0 with eConnectivity features that connect the machine to larger shop management systems for effective monitoring and increased machine utilisation.


New automation solutions, including Automatic Slug Management (ASM), Automatic Slug Welding (ASW) and Renishaw probing systems, reduce processing time by up to 20 per cent in lights-out production environments.


Additionally, the Cut P Series 350 and 550 can integrate with robots such as the System 3R WorkPartner 1+ that automatically loads and unloads parts for a single machine or within a two-machine automation cell that doubles machine production capacities.


With over 600 dedicated, pre-programmed cutting processes onboard, the machines optimise production for electronics, automotive, medical and mould and die manufacturers.


The machines can handle parts ranging from less than 1mm up to 800mm in height, weighing up to 6 000 kg in weight and made from a diverse range of materials including steel, carbide and copper to aluminium, titanium and graphite.
