Large Mold Shops can Boost Electrode Wear, Cycle Times with Workhorse Sinker EDM

The Gantry Eagle 1400 sinker EDM, according to MC Machinery Systems, is a true workhorse for all large mold shops, offering enhanced electrode wear — requiring less maintenance and costly downtime — and improved cycle times for high return on investment (ROI). It combines the latest in technological innovation with a human-centric design for utility across a number of projects, materials, industries and more.

Importantly, the Gantry Eagle 1400 retains the high-precision accuracy customary to the Gantry Eagle line but offers more working space to handle even larger jobs — maximum workpiece size is 59.4" W × 101.2" D × 31.1" H (1,500 × 2,570 × 790 mm).

Another feature, the Eagle PowerTec power supply reduces burn time and electrode wear without sacrificing accuracy. Using an adaptive current-shape generator, each discharge pulse is reported to calculate and create the ideal current shape to meet the exact discharge requirements at that moment. Moreover, combined with Eagle Power Jump, PowerTec reduces burn time by up to 50% while drastically reducing electrode wear — especially in graphite.

For fast, user-friendly operation, the Gantry Eagle 1400 also features a dual 32-bit, PC-based CNC control that enables faster data processing and servo control. The machine’s fixed table traveling gantry construction provides thermal stability and rigidity and features a four-sided drop tank design that allows work area access from all sides.

The EDM machine retains a fully integrated machine base fluid system, a direct drive AC smart servo system, dual ball screw gantry drive and a 3D lateral servo system. It also highlights an easy-access dual filter system and dielectric fluid emission. An automatic lubrication system enhances on-board automation capabilities.
