Synchronizing A Counterspindle - Siemens SINUMERIK 840D sl Turning Operating Manual

Procedure
Only those parameters relevant for stock removal with 2 synchronized channels of a workpiece
are subsequently described. All other parameters are described in Chapter "Contour turning".
Parameters
Parameter Description
Machining
● ∇ 2 CHAN
● ∇∇∇ 2 CHAN
Channel Defines whether the currently set channel is the leading or following channel.
All calculations are carried out in the leading channel.
Number Selecting the number of the partner channel if there are more than 2 channels avail‐
able.
● If, for the channel parameter, "Leading channel" is selected, then the channel
● If, for the channel parameter, "Following channel" is selected, then the channel
DCH Channel offset
● For positive parameters, then the leading channel machining is executed before
● For a negative parameter, when executing the program, the leading or following
● If the parameter is equal to zero, then balance cutting (axis coupling) is used.

Synchronizing a counterspindle

For multi-channel machines, the counter-spindle steps must be synchronized across all
channels.
You program handling the counter-spindle in one channel. This channel controls the motion of
the counter-spindle and adapts the zero offset of the channel.
In the synchronization step, the other channels park their tools in order to avoid collisions. The
zero offset is also accepted.
