BAOMA BM500B WIRE EDM MACHINES

Technical Description

The BAOMA BM500B is a closed-loop CNC wire EDM (Electro Discharge Machining) machine designed for extreme precision metal cutting applications. This system utilizes spark erosion technology, employing a molybdenum wire electrode to perform non-contact cuts through electrical discharge, enabling the machining of intricate, finely detailed components without applying cutting forces or excessive heat to the workpiece. The machine features robust travel capabilities with X-axis and Y-axis movement of 400mm and 500mm respectively, accommodating complex cutting geometries. It achieves exceptional machining accuracy of ±0.012mm octagon precision and produces superior surface finishes with roughness ratings as low as 1.2 micrometers in multi-cutting operations. The BM500B supports maximum workpiece thicknesses of 300mm with no taper angle capability. Equipped with advanced servo motor control and a BMW-2008 or BMXP controller, the machine enables direct CAD file integration through AutoCAD .dxf format compatibility. The wire electrode operates at diameters between 0.15-0.2mm with traveling speeds of 5-11 m/min, generating maximum cutting speeds of 150mm²/min. The system incorporates automatic wire tension mechanisms and high-precision linear guideways with ball screws for repeatability. Power requirements include 3-phase 380V/50Hz operation with 3KVA consumption. The machine utilizes BM-2 or BM-4 water-based working solutions in a 56-liter reservoir, maintaining optimal operating conditions. Weighing 2000kg with robust construction, the BM500B is certified to ISO9001 standards, making it ideal for precision manufacturing in automotive, aerospace, and tooling industries.
