MEX 2017 Micro-machining for electronic components meets stringent requirements

The AgieCharmilles Form S350 die-sinking electrical discharge machining (EDM) solution allow for electronic component manufacturers to easily and with repeatability deliver high machining accuracy to meet their information and communications technology (ICT) and automotive customers’ stringent quality requirement, GF Machining Solutions says.

According to GF, the machine's latest-generation intelligent power generator (IPG) has been conceived especially for superfinishing and precision applications. The IPG represents a breakthrough over standard EDM by overcoming historic process challenges when using copper electrodes, including electrode wear induced by electrical discharge multiple re-opening. Thus, speed improvements up to 40% and corner wear reduction of up to 50% can be achieved. As a result, manufacturers are virtually unlimited in their ability to achieve high accuracy, copy precision, surface quality and performance in any conductive material – even in mini and micro applications, the company explains.

Swiss-Act

How worthwhile is “Made in Switzerland”?

With the machine’s new discharge circuit for spark erosion power modulation and the flexibility to maximise material removal, customers can reach high levels of quality and efficiency. Finishing details are achieved by reducing the spark gap to just a few microns. At the same time, thanks to the machines embedded technologies, micro-machining processes are optimised so that they consume fewer electrodes. Reduced electrode consumption positively impacts customers’ profitability in a number of ways, including shorter machining times and reduced downtime.

Thanks to its short C-axis construction and oversize cast iron frame, high mechanical stability and precision are ensured throughout the lifetime of the machine.

GF Machining Solutions is in hall 5, booth C42 at MEX.
