Wire electrical discharge (wire EDM) machine
550 x 370 x 220 mm | U53j MAKINO

Makino's Uj series of WEDM machines, the U32j and the U53j, take accuracy and finish capabilities to a higher level. Targeted to applications in precision plastic injection molds, engineered plastics, precision stamping tooling, and medical and micro manufacturing, these machines are capable of producing geometric accuracies of ±0.00008" to 0.00012", and surface finishes down to 0.8 μmRy in tool steel and 0.5 μmRy in carbide. Static axis accuracies of 3 μm for straightness and 4 μm for squareness and parallelism are delivered from the factory.

These figures are achievable due to the mechanical accuracy and technology advancements built into each machine. The stacked cube design of the Uj series eliminates any possibility of overhang of any cast units when the axes are run to their full travel limits. This helps maintain straight, precise movement while eliminating droop as the axes move through their full travel. X and Y axis ball screws are 32mm, anchored at both ends, and laser aligned to high precision linear motion guides. As a testament to how well Makino WEDMs are built, we offer a limited 10 year or 20,000 hour ball screw warranty on these machines.
