Condition: used, Year of construction: 2023, operating hours: 120 h, Almost like new, a Haas TRT210 two-axis rotary table with only approximately 120 operating hours. The table was used exclusively on a Haas VF-4 (see separate listing) and is in flawless optical and technical condition. The TRT210 is Haas’s compact 5-axis solution for medium-sized VMCs, and it takes up minimal space by being mounted at one end of the machine table – the rest of the mounting surface remains free for vises or other fixtures. Plug-and-play connection to any Haas milling machine with 4/5-axis drives and the corresponding NGC control software. In addition to the rotary table itself, the scope of supply includes the matching toe clamp kit for direct mounting on the machine table, as well as a Renishaw riser block for side mounting of the radio receiver (OMI/OMP) – this ensures reliable signal transmission to the measuring probe even over the full A-axis swivel range.
