MITSUBISHI EDM RA90 WIRE EDM MACHINES

Technical Description

The Mitsubishi RA90 is a precision CNC wire electrical discharge machine engineered for high-accuracy cutting operations on conductive materials. Featuring a Mitsubishi RAS-1 64-bit CNC control system and 10.4" color LCD display, the machine delivers advanced machining capabilities with intuitive handheld pendant control. The machine accommodates workpieces up to 33.8" x 29.9" x 6.3" with a maximum weight of 771 lbs on a 22.5" x 18.8" table. Machine travels measure 12.6" x 9.8" x 6.49" on primary axes with 1.25" x 1.25" U/V travel, enabling complex taper operations up to 15 degrees at 4.0" depth. The non-submerged machining capability utilizes a 50A transistor pulse power supply for efficient wire cutting without fluid immersion. Supporting wire diameters from .004" to .012" with .010" wire guides included, the system incorporates a 118-gallon filter tank with 3-micron precision paper cartridge filtration. Additional integrated systems include a built-in automatic voltage regulator (AVR), power master control, and air cooling unit for thermal management during extended operations. The machine dimensions of 57" x 77" x 80"H with a total weight of 4,210 lbs provide a robust foundation for precision work. Rapid feed rate reaches 51.18 IPM, while the 22-pound wire spool capacity supports continuous production runs. Total power input requirement is 9 KVa, making this system suitable for job shops and manufacturing facilities requiring reliable precision wire-cut EDM capabilities without automatic wire threading functionality.
