With the new Eagle G50 Competiton series, it is possible to combine the workshop suitability of the Gantry Eagle 500 with the precision components of the G5 Precision in order to achieve high precision in a more economically way, OPS-Ingersoll states.

In the international tool and mould-making industry, the requirements currently split in two directions. On the one side, there is the “mass market”, in which quality requirements are still within a normally achievable range. On the other side, there is the absolute high-tech sector, where customers are confronted with increasing demands in terms of precision, especially due to increasingly complex automation solutions. For this area, back in 2018 OPS-Ingersoll had introduced the Eagle G5 Precision die-sinking EDM machine as a fully encapsulated machine.

This machine is less sensitive to short-term changes of the ambient temperature. However, the finest surface structures that can be achieved and the simultaneous reduction of wear require absolutely optimised processes. An effort that can be time and cost intensive for users. For this reason, the Burbach technology experts have decided to expand their line um and develop a new series of sinker EDMs by introducing the new Eagle Competition line.

The goal was to create a machine that is interesting for a wider range of customers in terms of technical specification, performance and price. This is important because even in standard toolmaking the trend can be seen that the accuracy requirements have almost doubled. Driven by the fact that — especially in tool and mould-making for medical technology, electronics, automotive and their suppliers — the challenges in terms of automation, material, wall thickness and precision will become significantly greater in the coming years: The Eagle Competition line now offers, for example, precision in multi-cavity machining that was not available in this class up to date.

Necessary and affordable for a large customer base

OPS-Ingersoll has upgraded the basic concept of the proven Gantry Eagle series with the innovations of the G5 Precision that have now been implemented in the Eagle Competition. These include the temperature control of the linear axis, the special temperature control of the working area as well as a new suction system for oil mist and fumes. The enclosure has been omitted in order to ensure optimum accessibility even for non-automated use. Besides the mechanical components, the machine is equipped with the new Eagle Powerspark One control system. Part of this control is the programming software Eagle Powerspark Editor (PSE). With the latter, OPS-Ingersoll redefines the user-friendliness, because even complex eroding tasks are easy to create and adapt. This is especially true for multi-cavity machining. With only a few clicks the number of inserts of each electrode and a wear compensation in the electrode manager can be configured and realised, the company promises.

The PSE is also the interface to almost all common CAD systems on the market. A vast number of parameters can be imported from CAD, which allow an almost automated program generation.

In combination with the advanced EDM technolog,y the Eagle Competiton is now capable to produce precise and finest surfaces with graphite up to VDI 12 in an extremely economically way.

In addition, PSE also offers a new copper technology. The Competition line concept is not only affordable for a larger number of customers, but also future-proof. The new line-up consists of two machine sizes: G50 and as G80 Eagle Competition, OPS-Ingersoll states.
