HAAS UMC-750SS CNC vertical machining center

HAAS UMC-750SS CNC vertical machining center built in 2018 in the United States is used for precision machining of complex workpieces with a maximum weight of 300 kg. The machine features a large work area which includes a direct-drive spindle, a 500 mm diameter rotary tilting table with a precision pilot hole and a measuring probe from the renowned RENISHAW brand. In addition, each tool taken from the 40-position magazine is continuously measured to ensure continuity of the machining process.

The UMC-750SS CNC machining center is offered with extensive equipment, which includes e.g. a belt chip conveyor and a perfectly optimised HAAS NGC CNC controller with many useful functions. To this date, the machine has run a small amount of time and has been used for prototyping, tooling production and small batch machining. The HAAS UMC 750 SS milling center weighs 8200 kg.
