How often should you lubricate a roll forming machine, and which lubricant to use?

Direct Answer

Lubricate gears, chains, and linear guide rails once per shift using heavy-duty lithium grease (NLGI Grade 2). For rollers processing prepainted galvanized steel, spray a water-soluble forming oil or light mineral oil continuously on the metal strip to reduce friction.

Key Engineering Guidelines

  • Precision Caliber: Ensure gradual bending stages to prevent metal micro-cracking and material stress.
  • Premium Tooling: Use vacuum-quenched GCr15 or Cr12MoV die steel for rollers (HRC 58-62) with hard-chrome plating.
  • Smart Design: Always calibrate lateral and vertical roll station alignment using a precise central wireline.
