ECM System Deburrs, Smoothes And Polishes

The CoolPulse ECM machine developed by Extrude Hone removes internal and external micro-burrs from metallic components, while also smoothing and polishing surfaces. The machine has been designed for two different modes of operation, with rapid selective change-over from one to the other. The ECM system is designed not only for “bath operation” but also for “benchtop operation” with the aid of a deburring fixture. In “bath operation” the workpiece is fully immersed in the electrolyte solution during the process. This results in all of the external surfaces being deburrred and polished in a single work cycle. The flow rate of the electrolyte is controlled by an agitator unit that provides the workpieces with a reciprocating motion within the tank. In addition, the electrolyte is also kept in continuous motion by blowing compressed air through the bottom of the tank. This has a positive effect on the machining quality and prevents flow lines and deposits on the workpiece, the company says.

The system is available with a power rating of 12 or 24 kW. Also included in the scope of supply of the basic module is a filter module for continuous cleaning of the electrolyte and a chiller unit which keeps the electrolyte at the required operating temperature.

Most metals can be machined, including mild steel, wrought iron, stainless steel, aluminum and so on. Along with other applications, the machine is suited for machining components in the medical technology and precision engineering fields, electrical and electronic components, automotive components as well as in micro-systems technology.
