Difficulties | a material that is difficult to shape or form |
not to invest capital to replace worn out machines, retool machines or add capacity | |
using equipment infrequently and can't justify the expense | |
benefit from the reduced machining associated with near net shapes | |
buying from machine shops and find the cost expensive | |
lack the skilled labor to produce precision, high-quality parts or who can't find skilled craftsmen |
Cold drawn products Features | Customer Benefits | |
Improved Size and Section | Tighter size & section tolerances | Reduces machining losses |
Dimensional consistency within each bar | ||
Dimensional consistency from bar to bar | ||
Better surface finish | Ground and polished | Reduces surface machining & improves quality |
Surface Improvement (Shaving or turning to produce "Defect Free" surface) | ||
Tighter straightness tolerances | Improved Straightness | Facilitates automatic bar feeding |
Increased Mechanical Properties | Yield strength | Can reduce the need for hardening |
Tensile strength | ||
Hardness | ||
Improve Machinability and Productivity | Increased machining rates | Enables higher machining feeds & speeds and improved machined finish |
Longer tool life | ||
Improved yield | ||
Improved Formability | Improves response to spheroidization Cold Drawn and Annealed | |
Improved Cost Effectiveness | Optimizes machinability and reduces yield losses |
