Wire-cut EDMs

August 27, 2010

Sodick Inc., a manufacturer of EDM technology, has released the VZ300L and VZ500L linear motor-driven wire-cut EDMs. The linear-motor system employs a direct-drive, frictionless, vibration-free mechanism with no backlash.

The machines feature glass scale feedback that provides true machine positioning at all times, the company reports. The scales are mounted on the moving axes; this enables them to measure machine accuracy consistently.

The recycle circuit saves on energy cost by recycling unused discharge pulses that were not originally used in the discharge process. The high-speed, electrolysis-free circuit eliminates oxidation and helps improve part straightness.

The machines are suitable for parts that require close-tolerance and fine surface finishes. The VZ300L features a 13.8- by 9.8- by 8.7-in. XYZ stroke and has a maximum workpiece weight of 1,100 lbs. The VZ500L features a 19.7- by 13.8- by 9.8-in. XYZ stroke and a maximum workpiece weight of 1,870 lbs.
