Notably, the Swiss-made generator and all the available features of the standard configuration make the FORM20/FORM 30 comprehensive partners in your production chain.
5
Versatile, reliable and easy to use The FORM 20/FORM 30 are amazingly flexible and easy to use, making it possible to cover a wide range of applications. Plus, they offer exceptional reliability and ease of use.
Mechanical structure
Solid structure for a reliable, stable operation
Rigid and compact The use of cast iron and the short C frame design ensure static and dynamic rigidity of the mechanical structure. The cross-table, fitted with linear glass scales, guarantees positioning accuracy. The ergonomics of the machine are designed to provide the most favorable ratio between the floor space area and the work surface area.
Linear Tool Changer (optional) Designed to be both economical and efficient, the fully integrated Linear Tool Changer (LTC) is ideal for less complex applications requiring few electrodes or involving longer cuts. FORM 20 : four positions FORM 30 : six positions
6
C axis (optional) A rugged C axis delivers high positioning precision (0.001°) regard­ less of electrode weight (up to 25 kg) and full machine current. Completely integrated, the C axis is easily extended to increase X and Y travels when machining very large parts. Thanks to the CNC-controlled C axis integrated into the quill of the Z axis, the FORM 20 and FORM 30 are incredibly flexible machines, with four axes that can be interpolated simultaneously. Allows curved recesses and undercuts by rotating the C axis and 3D vector widening.
Closed loop servo control Positioning measurements are done by means of linear glass scales fixed directly on the X, Y and Z axes of the FORM 20/FORM 30, thus eliminating errors that might otherwise arise when the screw thread becomes worn or too hot. Furthermore, before delivery, every FORM 20/FORM 30 is rigorously checked by means of a laser interferometer to guarantee the best possible accuracy.

Control
A custom-made interface
Maximize the productive hours In order to answer to these needs, AC FORM HMI provides new solutions : Complete machining report The jobs executed out are the subject of a detailed report containing the strategy, the discharge time, events, etc. These information can be exploited for : • Control the workpiece • Archive data • Enrich the know-how • Calculations of the production costs
10
Automatic sequence : choose your priorities Based on the machining strategies and number of electrodes and parts, the “ sequence ” screen automatically organizes the machining flow. This can be modified according to the criteria defined by the operator using the sequence wizard. After validation, the ISO program is generated, and you are ready for machining.
Generic optimum machining strategy AC FORM HMI offers clear choices for each application. It then generates the optimal machining strategies. The operator introduces, on a single screen, machining parameters such as : state of surface, depth, machining cycle, and type of application to extract the best generator performance.
Embedded documentation In order to avoid big workbooks, electronic documentation is embedded in the machine (HTML format). There is no need for printed information on the current screen, code programming, parameters of machining, maintenance, for example. With a simple touch, the necessary information instantly appears on the screen.

AC FORM HMI for increased productivity The development of this new AC FORM human-machine interface (HMI) is based on a study carried out with numerous mold makers to streamline the mold-making technique. The organization and layout of screens are a direct development of data derived from the study. This ease-of-use that has made GF AgieCharmilles interfaces so successful has not only been maintained but developed even further to benefit the mold maker’s task. The development of this new interface is based on a study involving more than 100 mould makers to define the mold manufacturing process. The organization of the functions and composition of screens are directly derived from data derived from the study. GF AgieCharmilles’ interface is based on a commitment to understanding and meeting customers’ needs.

Generator
Flexibility and power guarantee reliable results
Generator and technology The FORM 20 and FORM 30 are equipped with one of the most modern generators in the world for die-sinking EDM. Integrated into the generator is quality-boosting and cost-saving intelligence. The EDM process is continuously optimized with every impulse, drastically reducing electrode wear on even the finest finishes. Process control takes a fraction of a second and produces an extremely homogeneous surface finish.
The high-power generator has maximum output of 80 A on FORM 20 and 140 A on FORM 30. The generator’s switchgear cabinet is equipped with a closed water-air cooling circuit that is controlled by the cooling unit within the system. To ensure the longest life and reliability of the electronics, they are contained within a dustproof cabinet, in which the temperature is monitored and stabilized.
Surface homogeneity A uniform texture of the injected part is directly linked to the quality of surface finish. To respond to the need for a perfect surface finish to the mould, GF AgieCharmilles has developed a “ Surface ” technology designed to meet the most stringent criteria of surface homogeneity.
12
TECFORM The embedded TECFORM module allows the FORM 20/FORM 30 to quickly and safely achieve best performance and produce the desired results. Segment-dedicated technology means the operator doesn’t need to adjust the generator’s parameters. TECFORM improves and enhances your machining efficiency and dramatically reduces unproductive time.
Micromachining Especially when electrode dimensions are reduced, surface finish and wear become decisive factors in terms of performance. To address the needs of the connections and micromachining sectors in particular, GF AgieCharmilles has developed a dedicated module designed to reduce electrode wear by up to 30 % and to offer unequalled surface finish.
Job preparation
Easy setup for quick start of erosion
Ergonomic job preparation The most common measuring cycles, from simple measuring of Z level to rotating the workpiece around the C axis, are integrated into the control. Thanks to these measuring cycles, the position of the workpiece is plotted, eliminating the need for the operator to adjust the workpiece. This means the time to erosion is minimized and the workpiece can be placed in the working area without time-consuming manual alignment. The operator can start the erosion. The new FORM 20 and FORM 30 are ideal machines for inexperienced users in the field of general engineering and tool production. With the new FORM 20 and FORM 30, die-sinking EDM is no longer the domain of absolute experts.

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 EDM 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 millimeter 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 texturing Laser texturing 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 texturing, compared to conventional surface treatment using manual etching processes, offers economic, ecological and design advantages.
