Grinding with a B axis (only for cylindrical grinding
machines)
10.1

Overview

Cylindrical grinding machines with a B axis are supported by means of tool carriers.
Figure 10-1
Tool carrier
A separate tool carrier is set up for each grinding spindle. Each tool carrier has head kinematics
with the B axis as first rotary axis. A semiautomatic rotary axis in the direction of the grinding
spindle is set up as second rotary axis (values: 0° or 180°).
The respective basic position is determined via the offset angle of the B axis (e.g. 0°, 90°, 180°,
270°, arbitrary). If a spindle is mechanically at a slightly inclined angle to the 90° direction (e.g.
3°), then the direction vector of the second rotary axis is also entered accordingly (however,
the direction component Y must be 0).
Select the appropriate tool carrier in the "T, S, M" window.
"Beta" alignment angle
You can define a skew angle in relation to the basic position with β.
