Cylindrical grinding machine T series

workpiecehorizontalNC

INTRODUCTION
Designed for long shafts and heavy components up to 2000 mm between centers, the T-1280 and T-1680 are center-type cylindrical grinding machines that prioritize support and stability. Swing over table is Ø320 mm (T-1280) or Ø420 mm (T-1680). Maximum load held between centers: 100 kg (T-1280) and 150 kg (T-1680). An intuitive touchscreen GUI enables setup of grinding and dressing cycles without G-code programming. Reinforced bed rigidity and an integrated hydrostatic lubrication system reduce vibration during long-axis machining, enabling micron-level precision over long distances.
