Condition: used, Year of construction: 2023, operating hours: 120 h, Nearly brand-new Haas TRT210 two-axis rotary table with only approximately 120 operating hours. The table was exclusively used on a Haas VF-4 (see separate listing) and is in visually and technically flawless condition. The TRT210 is Haas's compact 5-axis solution for medium-sized VMCs and takes up minimal space at one end of the machine table – the rest of the clamping area remains free for vices 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 the side mounting of the radio receiver (OMI/OMP) – this ensures reliable signal transmission to the measuring probe even over the entire A-axis swivel range.
