  Lubrication Precautions for Three-Roll Plate Bending Machine

  The upper roller can be moved up and down using a lifting screw, turbine, and worm mechanism. All three rollers are driven by a motor and reducer.
  
  The upper roller is positioned symmetrically between the two lower rollers. It can be adjusted to a parallel or inclined position relative to the lower rollers using a manual clutch. This setup allows for controlled bending of the metal sheet or plate.
  
  The key advantages of this configuration are the simple and compact structure, ease of manufacturing and repair, lightweight design, and high precision of the forming process. However, it cannot bend the full length of the sheet, leaving slightly less than half the distance between the lower rollers as a straight, unbent edge (called a residual straight edge). This requires the use of pre-bending equipment.
  
  Establish a Dedicated Lubrication System:
  Implement a specialized lubrication system for the machine to ensure all critical components receive proper lubrication.
  This includes the mechanical drive shaft, sliding surfaces, and gear tooth surfaces.
  Select Appropriate Lubricants:
  Choose high-quality lubricants that are specifically recommended by the machine manufacturer.
  The lubricants should have the correct viscosity and formulation to effectively reduce friction, wear, and power consumption.
