AccuteX EDM, a division of Absolute Machine Tools Inc., has introduced its "SP-300iA" 5-Axis CNC Wire EDM. This machine features the latest "Microsparking Technology," the MST-II function that provides exceptional part finishes. Aerospace and medical industries in particular have demands for low recast and fine finishes. Further, this machine is built for rigidity with a Meehanite cast honeycomb base, highly-ribbed column that is mounted with oversized UVZ axis and reinforced lower arm for added stiffness. All castings are stabilized and subjected to rigorous testing to insure maximum strength, high precision, and durability.

The X, Y, Z working range is 13.8" x 9.8" x 8.7" U and V axes are both 3.15" The U-V axis mechanism is placed in a cabinet above the working area, assuring optimal rigidity and protection from humidity and physical damage. The axes are driven by means of closed-loop AC servo motors with 0.000004" resolution and controlled by a linear glass scale feedback system. The SP-300iA also incorporates the latest generation ball-retainer type guideways which reduce 90 percent of friction variation compared to conventional guideways.

The workpiece mounting table is made of hardened stainless steel, offers easy accessibility and is designed as a standard clamping system also. This creative solution reduces setup time. The table can also accommodate most commercial fixturing systems. All the operations relating to wire handling have been simplified on the SP-300iA. The machine is equipped with an annealing, fully automatic wire threading system with a tip disposal unit.
