GF Machining Solutions Debuts Automation-Forward EDM
With more than 600 pre-programmed cutting processes, the Cut P 550 Pro covers a wide range of parts in materials such as steel, carbide, copper, aluminum, titanium, polycrystalline diamond (PCD) and graphite.

The new Cut P 550 Pro electrical discharge machine (EDM) from GF Machining Solutions features the intuitive Uniqua human/machine interface (HMI), Intelligent Power Generator (IPG) technology and advanced Quadrax machine design.
The new Uniqua HMI features a 19" vertical touchscreen, full keyboard and mouse. For the utmost compatibility, Uniqua is said to support legacy file types from various EDM manufacturers and can create, import, modify and execute sequential (ISO-based) and object-oriented (dynamic) programs from previous versions of VISION and AC Cut HMI 2. With such capabilities, Uniqua works integrally with major CAD/CAM programs.
With IPG technology, the Cut P 550 Pro reportedly generates surface finishes as smooth as Ra 0.08 µm and heightens accuracy using integrated thermal regulation that enables the machine to achieve positioning precision of ±2 µm.
To protect the machine’s x-, y-, z-, u- and v-axes, its linear scales and rotary encoders form a double measuring system. In the event of a collision, the system differentiates between the linear and the rotary encoder, and an energy absorber system automatically stops the axes without damage to machine or workpiece. This full protection applies at machine speeds of up to 3 m/min.
The Quadrax mechanical system enables the Cut P 550 Pro’s table, work tank and dielectric liquid to remain stationary, as well as the workpiece, which enables the machine to accommodate heavier parts. Independent u/v and x/y axes with equal length (x = u travel; y = v travel), constant, lower mass and independent movement are said to produce large, precise tapered cuts. Additionally, a Rhenocast machine base reportedly offers lower thermal conductivity and vibration damping.
Automation solutions for the Cut P 550 Pro include Automatic Slug Management (ASM), Automatic Slug Welding (ASW) and the option of a retractable Renishaw mechanical touch probe to measure workpiece planarity and position on the machine's worktable. Scalable automation options from System 3R include a WorkPartner 1+ compact robot that can feed up to two wire-cutting EDM machines for more than two days to maintain unattended production.
With more than 600 pre-programmed cutting processes, the Cut P 550 Pro covers a wide range of parts from less than 0.04" to 15.75" (less than 1 mm to 400 mm) in height and weights up to 3,307 lb (1,500 kg), in materials such as steel, carbide, copper, aluminum, titanium, polycrystalline diamond (PCD) and graphite.
Wires are available from 0.003" to 0.013" (0.07 mm to 0.33 mm) diameters. Based on the Spark Track technology from GF Machining Solutions, the ISPS (Intelligent Spark Protection System) on each machine prevents wire breakage. The company’s intelligent iWire process detects variations in the workpiece profile and adapts wire spool unwinding speed accordingly to reduce wire consumption.
