T-shaped base frame Machining of large work pieces
Universal Clamping frame: thickness 45 mm for high solidity

Working zone
Easy accessibility to the working area and to the work clamping frame makes the mounting of work pieces a rapid operation.
The cramping frame is manufactured out of hardened steel with a thickness of 45 mm and is extraordinarity rigid.

Glass Scales for high accuracy To obtain durable accuracy, direct measurement of positions by linear scales is used. This system enables the actual movement of the slide to be checked directly. It eliminates all the classic errors that arise from the screw, such as backlash on reversal, expansion or wear. Accuracy does not vary over time and no subsequent calibrating is required. lntegrated Collision Protection The Z-Axis of CUT 20 P/30 P is equipped with Collision Protection. The ICP system prevents any breakage of sensitive parts and costly elements allowing
the operator to work with more confidence during job preparation and execution.

Base Structure The T-shaped base frame permits the loading of larger and heavy work pieces. The compact and rigid machine structure guarantees good positioning accuracy and highly repeatable results.
Lubricating system The unique design of the centralized lubrification system minimises the machining down time. It lubricates the guides and sliding blocks as well as the ball-screws, simplifying the maintenance tasks.

Machining of large work pieces
Designed to maximise its ctass leading work area size and travels.
Along with its advanced AWT greater productivity is achieved, as extended running during lights out is a reality. If large work pieces are needed to be machined the excellent accessibility allows a hassle free loading and unloading of work pieces of 1000 kg

High running hours
A large spool option is available on the CUT 20 P/30 P. A spool of
25 kg extends running hours and allows continuous production in combination with:
• Deionising bottle with a volume of 20 L (5.3 gal)
• 2 filter cartrídges of 450 mm heíght x 340 mm díameter each (17.71 x 13.38 іп)

Wire system
The wire system has been designed by GF AgieCharmilles and is an
optimized version from tried and tested solutions. The wire tension is monitored by an etectromagnetic break, CNC programmable. The wire spool storage has been designed to be easily accessible so that the operator can carry out a rapid change of spools.

Simple wire circuit
The concept of wire circuit is composed by very few components and consumable parts. They are: wire guides, wire contacts and pinch rollers. Besides the low running costs, the advantages of this system are a high reliability during threading, rethreading and functioning. As standard and to ensure unattended running hours, the equipment includes an automatic wire-threading and rethreading system.
The automatic threading is rapid and reliable whatever the type of wire used: hard or soft brass, coated or not. The key of success is preparing the wire properly before threading.

Powerful Generator
It integrates a SF (Fine Surfacel module with which a surfaces roughness of tess than Ra 0.25 μm (10 μiп) can be achieved. The generator, completely antielectrolysis, assures an homogenous and perfect surface finish. Along with the performance, the up-to-date electronics used in manufacturing ensure that the cost of ownership is the lowest possible.

High cutting speed
The thoroughly tested generator of the CUT 20 P/30 P with reliable electronics, is based on state-ofthe-art technology developed by
GF AgieCharmilles. Extremely high removal rates are possible with cheap brass wires, adding low hourly running cost to its unique features.

GF AgieCharmilles Generator
• Highest levet of performance
• High cutting speed
• Apptication oriented technologies
• Comptete technology range using wires from O 0.15 mm (0,006 in) up  0 0.30 mm (0.012 in)

Technologies
Thanks to the FPGA technology (Fieid Programmable Gate Arrays-a logic device programmabte instantaneously) and the completely digital process monitoring, servo response demonstrates a degree of flexibility that can only be achieved with a system designed specifically for EDM. The technology database package covers all requirements in a workshop. These technologies work with a variety of wires and encompass material ranging from steel to hard metals it also has the flexibility to produce results from rapid cuts to precision finishing cuts.

Speed technologies
The CUT 20 P/30 P has on board technologies that allow a unique
speed cut. These technologies optimise main, 2 and 3 d finishing
cuts, to attain the most common values of surface roughness, like Ra 0.60 μm (24 pin) and
Ra 0.35 μm (14 pin (to be achieved in a minimum of time. These high speed technologies, make the CUT 20 P/30 P a very powerful competitive production unit.

Strategy for stepped work pieces
The generator can manage and erode stepped work pieces. This function detects the difference of the material thickness in order to adapt automatically the power to the changing conditions.

Corner strategy
To ensure accuracy of:
• sharp angles
• small radii
the corner strategies adjust automatically the machining parameters during changes of direction. Even on the smallest details, high geometrical accuracy is obtained.

In case of power failure, the point and the job name are memorised, allowing a direct re-start of the job after power restoring.

Control unit
The graphics user interface is based on the Windows operating system and allows real time control of the EDM process. The system works with descriptive picture symbols and conversational screen pages following one after another in a logical way. This allows even new users to understand the WEDM principle quickly and means time to production is very short. The unique programming system also gives to the users a large degree of flexibility in a production environment, allowing a simple and fast setup and many hours of labour free running of the machine.

1 Job preparation
a. AC Easy Cam
The operator can easily prepare an ISO fite during the machining with an onboand CAM system. This powerful feature is standard and renders this product as a comptete solution from the contour creation to the part production. Data transfer:
• DXF import & export
• ISO export for CUT 20 P/30 P
• Possibility to import additional
NC code b. Most CAD/CAM programs worldwide are compatible with the CUT 20 P/30 P giving the operator a large level of integration.

Milling High-Speed and High-Performance Milling Centers. In terms of cutting speed, HSM centers are 10 times faster than conventional milling machines. Greater accuracy and a better surface finish are also achieved. This means that even tempered materials can be machined to a condition where they are largely ready to use. One essential advantage of HSM is that with systematic integration, the process chain can be significantly shortened. HSM has developed alongside FDM into one of the key technologies in mold and tool making.
EDM Electric Discharge Machines
EDM can be used to machine conductive materials of any hardness (for example steel or titanium) to an accuracy of up to one-thousandth of a mitlimeler with no mechanical action. By virtue of these properties,
EDM is one of the key technologies in mold and tool. making. There are two distinct. processes-wire-cutting EDM and die-sinking EDM.
Laser Laser ablation
Laser supplements and extends the technologies offered by GF AgieCharmilles. With our laser technology we enable you to produce texturizing, engraving, microstructuring, marking and labeling of 2D geometries right through to complex 3D geometries. Laser ablation, compared to conventional surface treatment using manual etching processes, offers economic, ecological  and design advantages.
