Wire electrical discharge machine UPN-01

CNChigh-accuracy

Ultra-precise machining and surface finish for small/fine wire operations 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 30µm diameter, and can operate with wire sizes ranging from 0.100mm down to 15µm in diameter. The UPN-01 is capable of achieving sub-micron level accuracy, which is made possible using the machines Pneumatic Static Pressure Guideways and Linear Motor motion technology. These two advanced motion control systems are combined to minimize mechanical friction and mechanical inertia to ensure consistent ultra-precision increment movements. The UPN-01 uses a 0.01µm or 10 nanometer scale feedback system, which provides a minimum programmable increment of 0.1µm that is capable of achieving a mechanical movement roundness of 0.2µm. The UPN-01 uses an oil di-electric system that provides greater control of the machining spark gap, which improves part accuracy, surface finish, and metallurgical quality. The machine can achieve surface finishes down as low as 0.02µmRa. The entire work zone is also enclosed and is temperature controlled to minimize thermal changes to the machine and work piece during long hours of operation.
