Steel broaching - Import export

Drawing is a process of cold metal forming, in which the processed material moves through a suitably shaped hole that is a special tool called a drawing die. The aim of drawing is obtaining products in the form of bars or wire with very precise cross-sectional dimen - sions, smooth, bright surface and specific mechanical properties. As a result of the drawing process material is strengthened which means increase in strength proper - ties and decrease in plastic properties.

The process is performed on a special machine – peeling line. Rotating head equipped with knives of carbide blades ensures the removal of surface layer with com - mon metallurgical defects. As a result of peeling one obtains a product with flawless surface and with high accuracy of diameter - class IT9.Mechanical properties do not change during peeling.
