Max. achievable cut angle accuracy:
AT-cut: Phi = 10 min, Theta = 15 sec
IT & SC-cut: Phi = 1 min, Theta = 5 sec
AC-cut: Phi = 10 min, Theta = 20 sec
Cut Y+5°: Phi = 10 min, Theta = 30 sec

Typical ranges of delivered cut angles of the blanks:
AT-cut: Phi = ± 15 min, Theta = ± 1 min
IT & SC-cut: Phi = ± 2 min, ± 5 min and ± 8 min,
Theta = above ± 15 sec
AC-cut: Phi = ± 15 min, Theta = ± 2 min
Cut Y+5°: Phi = ± 15 min, Theta = ± 3 min
