SEIBU ULTRA MM50B WIRE EDM MACHINES

Technical Description

The SEIBU ULTRA MM50B Wire EDM machine is a high-precision CNC wire electrical discharge machine designed for ultra-fine, complex cutting tasks. It features an X-axis travel of 20 inches, Y-axis travel of 14 inches, and Z-axis travel of 11 inches, enabling a substantial working envelope for intricate parts. Controlled by a FANUC 31IWB CNC system, it ensures precise coordination and control across multiple axes. The machine’s rigid construction uses Meehanite castings for superior stability and vibration damping, critical for maintaining a pitch accuracy of ±1 micron throughout operations. It supports wire diameters ranging from 0.004 to 0.012 inches (standard 0.008 inch), with an automated wire feeding device as a standard feature for consistent cutting performance. The Ultra MM50B delivers high cutting speeds while achieving exceptional surface quality through an advanced traveling system and optional insulating table to improve roughness. Its compact footprint measures approximately 92.3 inches wide, 104.9 inches deep, and 83.9 inches high, weighing 7,496 pounds, balancing robustness with space efficiency. Operating power requirements are a 3-phase 200/220 V supply with approximately 3.5 kVA consumption. This machine targets applications demanding ultra-precision and high-speed machining in die/mold manufacturing and other precision engineering fields, combining lasting durability with advanced CNC functionality and superior machining accuracy.
