Helio Brushing

Helio brushing is a surface treatment process for gravure cylinders and embossing rollers.

Brushing instead of polishing

Finishing with Helio brushing replaces conventional surface treatments with polishing stones. As a result, cylinder surfaces can be fabricated in a single process step with tight score spacing and the desired orientation.

Benefits:

      • Different surface roughnesses can be achieved in a controlled manner
      • Very uniform surface texture (Rz and Rmax nearly identical)
      • Very good printing results (no toning) due to tight score spacing (blade lubrication)
      • The orientation of the scores can be controlled
      • Long cylinder service life
      • Standard machines can be upgraded with a Helio Brushing unit
      • Can be integrated into existing polishing/finishing systems
      • Straightforward operation and parameter programming
      • Reduced production costs due to reduced throughput times
      • Supports wet and dry production process (no waste water)
      • Grinding agent savings (stones)
      • Minimum brush wear
      • Significantly cheaper than conventional polishing processes with significantly better quality!

Applications

      • For gravure cylinders and embossing cylinders
      • Copper surfaces - copper, steel and aluminium
      • Chrome surfaces
      • Deburring and cleaning of engraved, milled, etched and lasered cylinders
      • Cleaning and edge breaking on engravings

Specifics:

      • Accurate adjustments and control of contact pressure and speed
      • Touch screen with intuitive operation
      • Flexible uses due to low-profile installation height
      • Easily adapted on standard machinery
      • (bench polishers, lathes)
      • Identical with SA 100B design
      • With pneumatic height adjustment upgrade
      • Used primarily for embossing rollers
