The Makino U3 Wire EDM provides an ideal mix of speed, accuracy, and surface finish capability to tackle the most demanding applications. The machine utilizes a stationary work table design that delivers repeatable accuracy regardless of work piece size or weight. Excellent access to the work tank is provided through the pneumatic raise and fall front door, and the operator can access the underside of the work piece or lower machine head even with a large work piece on the table. The U3 machine uses a space-savings design that integrates the di-electrode reservoir into the base machine casting, reducing the footprint while improving thermal stability.
Machine maintenance on the U3 has been dramatically reduced with the development of the new PICO Round Wire Guide system. The Wire Guides can be removed and exchanged without the need for Vertical Wire Alignment, as the guide assembly will repeat to within 5µm. Indexing of the Energizer Contact Plates is fast with the Tool-less indexing design, which eliminates human indexing error by removing the need for special tools or measurement devices. The main di-electric filters are housed in a non-submerged cabinet that contains a Filter Air-Purge function that evacuates the water from the filters to simplify the filter exchanging process.
