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.

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.

Our work starts with precise and efficient material cutting using modern machines. Our Laser and plasma cutters are available for sheet metal processing of all grades. Laser Trumpf 4kW with interchangeable table 4000x2000mm cuts mild steel of max. 18mm with both oxygen or nitrogen. Plasma Omnicut/Hypertherm where portal is also fitted with an acetylene burner; table size 6500 x 2000mm, usually cuts max. thickness 100mm
