GF Machining Solutions has introduced its latest AgieCharmilles Cut P series of wire EDM machines. The Cut P 350/550/800/1250 models are equipped with efficient power generators and feature a robust design and build, intuitive HMIs, and several automation options for lights-out/unattended operations.

With Intelligent Power Generator (IPG) digital technology, the EDM machines deliver ultra-fine surface finishes (Ra 0.1) and can improve cutting speeds by up to 20%, says the company.
Several ‘Expert’ systems further optimise the IPG’s cutting performance, especially when undertaking demanding and challenging applications. For instance, POWER-Expert monitors and changes the power levels required to machine parts with variable heights. This system protects parts from unstable conditions at high cutting speeds. Simultaneously, the system controls spark parameters during finishing operations to provide high-quality surface finishes on variable height parts. This capability maximises part finishes and reduces the need for secondary bench work.
Regardless of workpiece height, another Expert system – WIRE-Expert – is used to control wire wear and achieve continuous geometrical accuracy from all directions.
For part profile accuracy, PROFIL-Expert automatically adapts the machining parameters and cutting path for rough and skim passes to control fine details and ensure positioning and contour accuracies of ±2 µm, while TAPER-Expert technology cuts angles from 0 to 30° (45° 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.
Cut P machines also feature GF Machining Solutions’ collision protection technology in the X, Y, U, V and Z axes.

Makino, which is represented in the UK by NCMT, has released its UP6 HEAT wire EDM for ultra-precision machining. The machine is capable of achieving workpiece positional accuracies of 1 µm, while providing XYZ travels of 650 x 470 x 320 mm.

Designed for precision stamping and fine-blanking applications, the machine is suitable for electric motor stator die tooling. The Makino UP6 HEAT features a stationary work table design that helps improve positional accuracy, as the machine is moving the same mass regardless of workpiece weight. A programmable rise and fall three-sided work tank is deployed that provides ergonomic access to the work zone; a configuration that also simplifies requirements for automation.
The machine contains several features that are designed to provide high levels of long-term thermal stability, such as integrating the water di-electric reservoir into the base casting of the machine, which also minimises floor-space requirements. Makino’s UP6 HEAT employs active thermal cooling of the entire structure, whereby chilled di-electric fluid is circulated through the casting to maintain a constant machine temperature.
Hyper-i control, with its 24” HD touch screen, operates like a common smartphone or tablet. The Hyper-i control delivers a common interface that is used on both Makino wire and die-sink EDM machines, and contains many helpful advanced functions that support the needs of the operator to boost productivity. UP6 HEAT also comes as standard with the HyperConnect IIoT network connectivity function for remote machine monitoring and interconnectivity of all manufacturing information.
