Micromachining Operation

July 6, 2010

The CUT 1000 from GF AgieCharmilles was specifically designed for micromachining by using wires just 0.02 mm in diameter. According to the company, the machine’s IPG-V’s eCut technology allows this wire EDM to achieve surface finishes down to 0.05 µm Ra in continuous operation.

The machine is equipped with technology called AC Duo, which makes it possible to work with two wire spools, each with a different wire type, and switch between wires of different diameters automatically. Programmable via the machine control, the forward feed of the wires, just like the threading, takes place automatically and is monitored by sensors.

The table design separates the X and Y axes on a patented monobloc, eliminating mutual interference and tripping errors. In addition, a traveling table on the machine bed carries the worktank 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 company states.

Workpieces weighing up to 77 lbs. can be accommodated, and the X-, Y-, and Z-axis travels are 8.66- by 6.29- by 3.93-in.

Additionally, the control system, called Vision 5, was specifically developed for wire cut EDM work.
