For what parts of the process, what is the difference between the installation
With the knife is like a long knife, to prevent the use of knives to make the knife, the center frame is used for the processing of slender shaft, to prevent the processing of slender shaft shape into the middle of the coarse two fine
When turning slender shafts, the central frame can be used to increase the rigidity of the workpieceWith the tool holder fixed on the bed saddle, there are generally two supporting claws, with the tool holder can follow the movement of the tool to offset radial cutting can increase the stiffness of the workpiece, reduce deformation. So as to improve the shape precision and reduce the surface roughness.
The central frame is mainly used for supporting and fixing the shaft parts or strengthening the rigidity.The difference is: the 1 position is different; the center frame of the 2 does not move with the carriage.
