MAKINO U3 WIRE EDM MACHINES

Technical Description

The Makino U3 Wire EDM is a precision CNC machine designed for high-accuracy electrical discharge machining applications. This five-axis system features X, Y, and Z-axis travels of 14.6, 10.6, and 8.7 inches respectively, with additional U and V-axis capabilities of ±2.0 inches for advanced angular cutting operations. The machine accommodates workpieces up to 30.3 x 23.2 x 8.7 inches with a maximum load capacity of 1,323 pounds on its 24.8 x 17.7-inch three-sided table. Equipped with Makino's intuitive Hyper i CNC control system, the machine operates using a stationary worktable design that delivers repeatable accuracy regardless of workpiece size or weight. The U3 supports wire electrode sizes ranging from 0.004 to 0.012 inches in diameter, with programmable wire tension between 0.45 and 5.62 pounds-force and servo feedrates from 0.00039 to 1.97 inches per minute. The machine features a 31.1 x 24.0 x 10.0-inch inside tank dimension with integrated dielectric filtration and a complete spent wire cleaning and drying system. Advanced features include automatic wire threading with break-point capabilities, crash prevention, automatic power recovery, and a PICO precision guide system. The machine weighs approximately 7,054 pounds and provides rapid traverse speeds up to 78.74 inches per minute, making it suitable for demanding applications requiring speed, accuracy, and superior surface finish quality.
