Accuracy of

Feed Axes
In the total error budget of a machine tool, the positioning error values
of the feed axes play a critical role. The conclusion of this two-part series

Description: Under the same conditions, also with 6,000 rpm, it shows a maximum linear deformation of {x: 5 m, y: 45 m, z: 55 m}. The rotational deformation reached a maximum of {a: 25 m/m, b: 10 m/m}. The third machine was equipped with a high-speed spindle and jacket cooling. At 12,000 rpm it showed linear deformations of {x: 5 m, y: 5 m, z: 40 m} and rotational deformations of max. {a: 20 m/m, b: 30 m/ m}.
