Mitsubishi EDM (Wood Dale, IL) has introduced the S Series to the FA line. Features previously offered only as upgrades are now considered standards in both the FA10S and FA20S machines.

The Series’ anti-electrolysis technology helps achieve its high precision machining. The new high-speed PM4 control enables full automation from rough to finish machining. PM4’s stepped shape capabilities allow multiple parts with different shapes and thickness to be machined without setting specific electrical conditions. SL (Step Less) control—developed for the FA-P Series—has improved accuracy for finishing step shape workpieces. Straightness and corner accuracy on complicated parts can now be easily machined with high precision. Another high precision feature of the FA-S Series is the EM (Entrance Master) control, which reduces the small dimple at the program approach point.

Many standards have been incorporated into the machines—including XY linear scales, .004-inch wire capable automatic threading, and all-axis absolute control, which enable highly accurate positioning without returning to zero after power failure. The machines can achieve fine surface finish machining with the workpiece placed directly onto the table. Because an insulation jig is no longer needed, setup is simpler and better able to accommodate automation. The FA20S also has an Angle Master option, which will allow for a taper angle of up to 45 degrees per side by using the new standard long stroke taper.

Additionally, consumable and electrical costs have been greatly reduced by using the CS (Cost Save) mode. The 16-Step Programmable Flushing is now standard due to the dielectric fluid pump inverter control system. Many self-cleaning features that have reduced maintenance time by up to 90 percent in the FA Series have been enhanced in the new FA-S Series.
