As the Northeast U.S. representative for SARIX microEDM equipment, Leer Technologies Inc., Claverack, N.Y., spent the better part of EASTEC 2008 showing off the newest features of the SARIX-200 3D MicroEDM Milling machine.

Cutting Tool Engineering spent a few minutes with Graham Ruck, sales/applications manager for Leer, at EASTEC this past spring to get a brief overview and demonstration of the microEDM milling machine.

A typical machine configuration includes:

• 3D micromilling of complex forms with radius corner down to 3µm,
• High precision of smaller, deeper and more precise round holes,
• High surface finishing of microsinking cavities,
• New on-board, user friendly unlimited programming and editing software,
• New CAM SARIX Module compatible to ESPRIT CAD-CAM software, integrating the new Micro-EDMing process multi-axis-multi-step for machining down to 10µm with R_a up to 0.05.
• High precision machining and accuracy up to ±1µm.
• Microfine pulse shape generator, SX-MFPS, for 3D microEDMing using tubes and solid electrodes from 5µm to 3.0mm,
• MicroEDM drilling technology with automatic breakthrough detection device,
• Up to 8 axes for complex workpieces with X-Y-Z, back slide W-axis (Z2), C and A/B indexing axes.
