The Makino U3 Wire EDM utilizes a stationary work table design that delivers repeatable accuracy regardless of work piece size or weight. It can accept work pieces up to 770 x 590 x 220 mm, weighing up to 600 kg. The Wire Guides can be removed and exchanged without the need for Vertical Wire Alignment, as the guide assembly will repeat to within 5µm (0.0002”). 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.
