Thread drills, milling cutters, and thread forming tools are measured without distortion, contact-free, and with µm precision – the genius cannot do this. - Threading programs without programming: Flank diameter, pitch, flank angle, lead angle, back taper, taper; metric, UNC/UNF, Whitworth, trapezoidal, and round threads. - Grinding wheels and grinding wheel packs are detected and automatically measured via type selection (MP 410). - Fully automatic, operator-independent measurement with test protocol – reproducible, documented, and ensuring reliable handling of complaints. - Spindle ace: Run-out ≤ 0.002 mm, changeover accuracy 0.001 mm (according to the manufacturer). - Full enclosure protects against dirt and stray light – can be used directly in production instead of in the measuring room.
