Separate X- and Y-Axes Eliminate Errors in EDM Micro Machining

Wire EDM ideal for micro machining and ultra precision applications.

Machining accuracy and surface protection comprise two of the top priorities for GF AgieCharmilles (Lincolnshire, IL) as it developed the CUT 1000 OilTech, a wire EDM created for manufacturers machining micro components or requiring high accuracy.

Designed specifically for micro machining and ultra precision applications, the machine uses wires as small as .02 mm diameter and SF technology to achieve surface finishes down to Ra 0.05 µm in continuous operation and impeccable corner quality. Furthermore, it utilizes oil as an inert dielectric.

The oil eliminates the effects of corrosion due to long periods of immersion in the workpiece. The oil also enables smaller distances between the wire and workpiece to produce smaller internal radii when compared to water-based machining.

Programmable via the machine control, the forward feed of the wires, just like the threading, takes place automatically and is monitored by patented sensors.

GF AgieCharmilles constructed the CUT 1000 OilTech with a table design that separates the X- and Y-axes on a patented monobloc, eliminating mutual interference and tripping errors. A traveling table on the machine bed carries the work tank and moves the workpiece in the X direction exclusively.

A second axis slide, also movable in the horizontal plane on the machine frame, accommodates the upper part of the C-frame and moves the wire in the Y direction. This configuration delivers ideal travels, positioning accuracy and taper cutting capability for machining complex, high precision parts.

The CUT 1000 OilTech accommodates workpieces up to 77 lbs and has X-, Y- and Z-axis travels of 8.66 in x 6.29 in x 3.93 in, respectively. Additionally, the machine is equipped with Vision 5, an intuitive control system developed specifically for wire cut EDM that enables flexible data input in accordance with workshop environment.
