In late March, our three high speed CNC milling machines were two colour interferometrically re-calibrated
by CD Measurements Ltd.

Our new factory provides a much more stable environment for these machine tools, and very tight tolerances
were achieved, as follows

DMG 50 V:   1.46 uM in X, 1.37 uM in Y and 1.65 uM in Z

Secondly, our

Bostomatic:  3.2 uM in X, 1.57 uM in Y and 3.7 uM in Z

 and finally our - recently purchased

Matsuura: 6.96 uM in X, 5.69 uM in Y and 6.94 uM in Z

 The full calibration files are available here:
