The UPN-01 represents the next leap forward in technology for ultra-precision machining and surface finish capability of small/fine wire operations. The machine features a unique horizontal wire drive system layout that enhances wire threading performance, and is capable of reliably threading start holes as small as 0.001” (0.03mm), and can operate with wire sizes ranging from 0.004” (0.100mm) down to 0.0006” (0.015mm) in diameter.
