Discover how PECM and the PEM 3.1 SX are shaping the future of contactless, ultra-precise machining.

The PEM 3.1 SX is engineered for manufacturers seeking stress-free, contactless, and thermally neutral metalworking—ideal for high-performance industries such as aerospace, medical technology, toolmaking, and energy. All this without tool wear.

Key Features & Performance

• Machine table Area: 540 x 520 mm
• Machining Area: 32cm²
• Electrode Feed Rate: 2.00 mm/min
• Machining Gap: Typically 5–80 µm
• Surface Quality: lowest achievable Ra: 0.0015 µm
• Accuracy: < ±3 µm
• Cycle Time Optimization: Simultaneous machining of multiple parts in the same time like one part

The PEM 3.1 SX uses pulsed current combined with a tailored electrolyte flow to precisely remove metal from electrically conductive workpieces—without generating mechanical forces, heat and without any contamination of the surface. This eliminates thermal distortion, microcracks, or burrs, while enabling machining of hard to machine and even hardened materials such as tool steels, titanium alloys, nickel based alloys or cobalt-chromium.

Highlights & Innovations

• Integrated Axis Control: The SX variant includes enhanced axis control and machining gap control,enabling superior stability and repeatability in dynamic machining conditions.
• Closed-Loop Monitoring: Intelligent sensors monitor all process relevant data, and gap width in real time, ensuring maximum reliability, repeatability and part quality.
• Modular Design: The system can be customized,  ready for simultaneous multiple part processing or adapted to customer-specific automation solutions.
• Digital Interface: OPC UA-ready and compatible with Industry 4.0 environments for smart factory integration.

Application Scope

Whether producing micro-structured valve plates, surgical implants, or components with challenging undercuts or internal spirals, the PEM 3.1 SX delivers consistently high performance and scalability in both prototyping, small batches and series production.

Its ability to produce tight tolerances, fine radii, and burr-free and polished surfaces in a single operation—without post-processing—makes it one of the most efficient solutions for modern precision manufacturing.
