New Wire Technology for 24/7 Production Work

As manufacturing opportunities in the medical market continue to grow, Mitsubishi EDM delivers a new wire technology designed specifically to meet the field's production work requirements with high speed and precision.

The MD+PRO features a full servo B-axis indexing option. Integration of the B-axis introduces two new processes for EDM: indexing, and turning and burning. These features have brought EDM into several new manufacturing markets, including medical. Recent installations combine this technology with a WorkMaster robot to meet industry demands for high-precision machining and to achieve 24/7 production capabilities.

Tipping the wire during machining sacrifices speed and accuracy. Indexing capabilities of a B-axis on a wire machine preserves accuracy with guaranteed angle precision. Without a B-axis, parts need to be manually re-positioned to achieve additional cut angles, involving operator intervention, which leaves greater room for error.

According to Mitsubishi, one of the greatest advantages of a B-axis is its ability to hold a fixture for multiple part setup. A fixture holding multiple parts will automatically index, increasing the machine's ability to cut faster. A robot can continually load fixtures for more unmanned operations.

Anther advantage of the B-axis is its turn and burn capability which replaces the need for secondary and finishing applications. The continuous rotation of the B-axis simulates secondary operations such as grinding.

The machine's anti-electrolysis technology helps achieve high precision machining. Furthermore, the MD+PRO's new high-speed PM4 control enables full automation from rough to finish machining. PM4's stepped shape capabilities allow multiple parts with different shapes and thickness to be machined without setting specific electrical conditions.

SL Control improves accuracy for finishing step shape work pieces. Straightness and corner accuracy on complicated parts are now easily machined with high precision.

The MD+PRO's CS (Cost Save) mode greatly reduces consumable and electrical costs. Its dielectric fluid-pump inverter has a 16-step programmable flushing control system. It also has several selfcleaning features for reduced maintenance time and optimum long-term performance.

Standard with the MD+PRO is .006~ .012-in. wire-capable automatic threading and an all-axis absolute control, which enables highly accurate positioning without returning to zero after a power failure. TMD
