Cold drawn steel advantages: | |
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. | |
