SST, a global distributor of machine tool and consumable brands, announced its collaboration with SmalTec International to bring the EM203 and GM703 micro-precision electrical discharge machines (EDMs) to SST’s West, Mid-Atlantic and Northeast regions. Based in the Chicago area, SmalTec is a micromachine manufacturer known for high- and ultra-high precision equipment and providing comprehensive turnkey solutions.
“This complementary partnership signifies our commitment to offer a range of solutions specifically for extreme precision in micro sized 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 3-D designs using a 0.30μm spark size at a 5-nanosecond frequency, the industry’s smallest and fastest spark size. Tolerances are held within 10nm, creating unrivaled surface quality and feature-size capabilities. Polishing can be completed on the inside of micro holes, features, mold cavities, or pins. Additionally, micro holes 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 and advanced in situ metrology process, electric flux measurement (EFM), which 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. Micro probes used with EFM can be custom-shaped using the micro-EDM. Today, micro features 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.”
