R2: Rotary axes
12.1 Brief Description
Typical applications
● 5-axis machining (operating range limited or unlimited)
● Rotary axis for eccentric machining (unlimited operating range)
● Rotary axis for cylindrical or form grinding (unlimited operating range)
● C axis with
● Rotary axis on winding machines (unlimited operating range)
● Rotary workpiece axis (C) on hobbing machines (unlimited operating range)
● Round tool magazines and tool turrets (unlimited operating range)
● Rotary axis for peripheral surface transformation (limited operating range)
● Swivel axes for gripping (operating range 360°)
● Rotary axes for swiveling (operating range < 360°; e.g., 60°)
● Milling swivel axis (A) on hobbing machines (operating range, e.g., 90°)
Axis addresses
Coordinate axes and directions of movement of numerically-controlled machine tools are
designated according to DIN.
DIN 66025 specifies the following axis addresses for rotary or swivel axes:
● A, B and C with X, Y and Z as middle axis
● The positive rotary-axis direction of rotation corresponds to a clockwise rotation when

(unlimited operating range)
TRANSMIT
This means that A rotates about X, B rotates about Y and C rotates about Z (see fig.).
looking in the positive axis direction of the corresponding middle axis (see fig.).
