Why the CNC lathe workpiece with the top after the top of the spindle will ring
Tight enough to properly relax, some of the precision screw parts in the processing also need to loose at the top to prevent parts of the thermal expansion and contraction of parts.
These two cases can be turned around with the spindle to see if the same gear is not the same as when the top can be flexible.
Spindle and tailstock are not generated by the heart of the positioning,
Slender shaft requirements to withstand the workpiece hand can turn the top tip, the tool to ninety degrees positive side knife.
