MikroTurnGrind 1000

For finish hard turning and finish grinding workpieces up to Ø 380 mm or Ø 200 x 1000 mm between centers. Equipped with a Siemens 840D SL control.

The MikroTurnGrind 1000 is the solution for the finish hard turning and finish grinding of complex workpieces in one chucking. Ideally suited for short run, multiple surface parts with sub-micron precision requirements. The MikroTurnGrind 1000 makes workpieces up to Ø 380 mm or Ø 200 x 1000 mm between centers with a max. hardness of 70 HRC. Achievable accuracies:

-Surface finish (Ra) 0.1 µm
-Form accuracies 0.1 – 2 µm
-Size accuracies ≤ 1 µm
