Tube Drawing Oils

BECHEM tube drawing products are used for forming of tubes, hollow profiles or round bars, no matter whether blasted, annealed or pickled materials are involved.

The Copper tube drawing process has many important factors that affect the quality and precision of formed tubes, such as die angle, drawing speed, reduction ratio, effective lubrication etc. Precise operational parameters can reduce uneven deformation and excessive residual stress, preventing intrinsic defects, surface cracks and wrinkles.

During the drawing process as the copper tube passes through draw die and over the ‘internal diameter (ID)’ mandrel, the surface of the tube extends to a great extent. Lubrication plays a critical role in minimizing friction and temperature rise at the work surface in order to achieve higher process efficiencies and product quality.

The lubricant needs to reduce friction and manage temperature by forming a resilient film that can withstand high surface pressures between the workpiece and draw tool.

Impact of ineffective lubrication on tube drawing

  • Drawing oil that cannot endure surface pressures can lead to friction, rise in temperature, accelerate die wear and ultimately result in poor surface finish and defective cracked tubes

  • Lack of lubrication can result in breakage of the mother tube during the interim drawing processes of pilgering, spinner block and straightening, leading to line stoppage and affecting operational productivity

  • The lubricant quality can affect surface blackening and result in tarnish on the drawn tube. Removal of undesired residues on the ID and OD of the tube is a tedious process

  • Increase in temperature due to friction and overheating between the tool and workpiece can accelerate oxidation rate and drain out the lubricity additives from the lubricant, further deteriorating its quality and life
