VELTRIX THREADPRO TP-760
Heavy-duty CNC external thread grinding for large-diameter components.
The TP-760 is the larger-capacity sibling in the THREADPRO external grinding line, built for components up to approximately 14.4 in (367 mm) in grinding diameter and grinding lengths up to approximately 33 in (838 mm). It carries the same rigorous automation, monitoring, and safety package as the TP-715, scaled up for heavier workpieces and longer thread runs — making it the platform of choice for large fasteners, lead screws, and heavy transmission components.
