1.It can remove the Size and Section which provides Tighter tolerances which Reduces machining losses.
2.It can remove the  Steel Surface Finish which Reduces surface machining & improves quality.
3.It can remove the  Straightness which Facilitates automatic bar feeding in CNC.
4.It can increase the Mechanical Properties which Can reduce the need for hardening.
5.It can improve the Machinability and Productivity which Enables higher machining feeds, high tool life, yield & speeds and improved machined finish.
