LOEWER K -Abrasive Belt Unit with Contact Drum

The abrasive belt unit with a contact drum can be used for graining a decorative straight-line finish or for deburring. Depending on the application the hardness and diameter of the contact drum can be selected accordingly. For example a harder drum is ideal for straigh-line finishing whereas a softer drum works better for deburring.

  • Decorative straight-line finish

The abrasive belt units can be equipped with the unique LOEWER floating head system, which allows the entire unit to move out of the way if the grinding pressure gets too high. The system prevents the workpiece overheating and protects the expensive contact drum from damage.
