Wire EDM electrical discharge machine UX3i

high-accuracyprecision

Product Overview
The UX3i is a high-precision wire EDM (UXi Series) designed for tight-tolerance machining. The HFG Generator enables higher frequency with lower current to improve surface finishes while increasing machining speeds; example: a 50 mm H13 punch machined to a 10 µin Ra target achieved 8 µin Ra using four-pass machining with ~5% reduced cycle time.

UXi Series Features

• Internal radiator cooling for improved thermal stability of the machine casting.
• High-accuracy chiller maintaining temperature within ±0.1ºC to limit thermal drift affecting accuracy.
• Higher flatness accuracy worktable to improve static accuracy.
• Auto seal plate shower for seal plate lubrication and cleanliness.
• Hyper Drive Extreme Wire Guide System driven by AC servo motor tensioning for a broader wire tension range and enhanced dynamic corner control.
• Consistent wire tension for precise results in complex cuts; dynamic corner control included in the cutting technology database to improve straightness, size, shape and corner accuracy.
• Jet-less threading enabling threading of interrupted/hollow parts and very small start holes.
• Enhanced auto-wire-threading with annealing process to straighten the wire for reliable, repeatable threading.
• Hyper Drive Extreme auto-threading allows threading in the gap after a wire break, reducing recovery time in many applications.

HFG Generator Example
The HFG Generator permits higher frequency at lower current to improve surface finish and increase cutting speed. In a representative test (H13, 50 mm punch), four-pass machining produced an 8 µin Ra (0.20 µm Ra) finish versus the 10 µin Ra (0.25 µm Ra) target while reducing machining time by approximately 5%.
