Product 5
Highest straightness with hydrostatic guideways
The CNC hydrostatic guideway grinding machine JM-2070CNC uses fully hydrostatic guideways on the X and Z axes – friction-free and without stick-slip. Combined with linear motors and a marble bed, it achieves straightness below 0.001 mm and positioning accuracy of ≤ 0.0015 mm.
