Type: Live centers series
Duty: Medium
Application: CNC lathe, high speed lathe and other lathe.
Working Usage: Applicable for the length less than 400mm ordinary turning process, and slender workpiece turning process.
Structure The radial load and axial load designed separately. Adopted double row ball precision bear and thrust bearing and needle bearing.
Accessories For SC-69-M-3A/4A/5A, Y type spanner
TIR Less than 0.002mm
Inspecting the run out accuracy of the center tip must be under the
status of holding the workbar tightly.
There is S model of light duty type, same spec, which can improve the issue of deformation of processing slender workpiece
