Centre drive spindles are used if the run can only be achieved at the points to be machined in the same clamping and the workpiece has therefore to be accessible from both sides.
Workpiece examples centre drive spindle
Pneumatic swivel module
Machining of two bearing seats in one clamping.
Configuration example centre drive
Machining from bar, counter spindle as centre drive
Transmission shaft
Machining from bar, counter spindle as centre drive.
The bearing seats on both ends can be produced in tha same clamping.
Thus, running accuracies << 0,01 mm.
Micromotors
The connection ground at both ends can be produced in the same clamping.
Thus, running accuracies << 0,01 mm.
Writing instruments
The connection ground at both ends can be produced in the same clamping.
