Advantages and Benefits of using Cold Finished Bright Bars - Page 3
3. Surface Integrity: Cold drawing or grinding and polishing greatly
improves the surface texture, which can:
Reduce or eliminate machining.
Ease manual handling and machine loading.
Significantly improve eddy current testing sensitivity and reliability
Turning and/or grinding rids a bar of its surface anomalies, which can:
Eliminate decarburization
Provide a defect-free surface
Reduce need for all-over machining
4. Machinability: The increased beam strength, reduced ductility,
clean surface and improved dimensional accuracy of a cold drawn bar can
positively affect machining performance by:
Allowing the use of rapidly activated, precision colleting
Increase work-holding security with larger bearing contact areas
Improve the machined surface finish through reduced tool-edge weldments
on ductile grades
Improve part size control through less lateral deflection
Increase tool life through more stable tool-edge weldments on ductile
grades as well as from reduced abrasion with oxide-free, bar surfaces
Reduce wear on machine parts and collets and less lubricant
contamination due to the absence of hot mill surface scale and/or corrosion
products
Allow the use of higher spindle speeds with the reduced propensity for
vibration
Reduce screw machine maintenance
Summary
In summary, cold finished steel bars enable design engineers to reduce
manufacturing costs and time, and produce superior performance components. Cold
finished steel bars are the value-added engineering material of choice for a
universe of precision components in almost every industry.
