# Makino UX6i

Hardware · `UX6i` · verification: source checked

The Makino UX6i is a wire electrical discharge machining (EDM) machine in the UXi series. It uses an HFG generator and a Hyper Drive Extreme wire guide system with AC servo wire tensioning. Its worktable measures 910 x 710 mm, with X, Y, and Z travels of 650 mm, 450 mm, and 420 mm.

## Study notes

- The UXi series uses an internal radiator cooling system and a chiller that maintains temperature within ±0.1 °C.
- The Hyper Drive Extreme wire guide system is driven by an AC servo motor tensioning system.
- The HFG Generator uses higher frequency and lower current to improve surface finish.
- In the document's example, a 50 mm thick H13 tool steel punch was machined to 0.20 µm Ra in four passes with a 5% reduction in machining time versus a 0.25 µm Ra target.
- Jet-less threading is intended for interrupted or hollow parts and extremely small start holes.
- The auto-wire-threading system uses an annealing process to straighten the wire.
- After a wire break, the auto-wire-threading system can thread in the gap for specific applications.
- U-axis and V-axis travel are each ±75 mm.
- Available wire diameters are 0.100 mm, 0.150 mm, 0.200 mm, 0.250 mm, and 0.300 mm.
- Tank size is 1,070 mm x 880 mm (42.12 in x 34.64 in).
