Single Source Technologies, Auburn Hills, Mich., a distributor of machine tools and consumables, is collaborating with SmalTec International LLC, Naperville, Ill., to bring the EM203 and GM703 microprecision EDMs to SST's West, Mid-Atlantic and Northeast regions. Based in the Chicago area, SmalTec is a prominent micromachine manufacturer known for high- and ultrahigh-precision equipment and providing comprehensive, turnkey solutions.

"This complementary partnership signifies our commitment to offer a range of solutions specifically for extreme precision in microsized components," said Mark Logan, director of business development, SST. "We recognize that many manufacturers consider micromachining to be difficult, if not impossible, to manufacture commercially. For that reason, we are pleased to bring technologies that deliver on accuracy and surface finish requirements to these customers through our partnership with SmalTec."

SmalTec's EM203 and GM703 micromachines combine high-precision CNC technology with highly adaptive EDM sensing and machining. These models create complex 3D designs using a 0.30µm spark size at a 5-nanosecond frequency, the industry's smallest, fastest spark size. Tolerances are held within 10nm, creating unrivaled surface quality and feature-size capabilities. Polishing can be completed on the inside of microholes, features, mold cavities or pins. Additionally, microholes with significant aspect ratios are achievable, from 10:1 at 5µm to 40+:1 at 100µm.

The EM203 and GM703 have recently been upgraded to use a new, advanced in situ metrology process: electric flux measurement. EFM is a patented process that uses a traditional CMM-style methodology but senses the proximity of a surface before coming in contact with it, making it nondestructive. Microprobes used with EFM can be custom-shaped using the micro-EDM. Today, microfeatures can be created and measured at nanometer precision during the machining process.

"Working with SST will enhance our market penetration into high-volume production customers and allow us to better serve manufacturers across industries, including medical, aerospace, semiconductor, optics and automotive," said Jerry Mraz, general manager and owner of SmalTec International. "We are thrilled to broaden our capabilities and offerings, as well as our reach."
