OHIO’s Head Refurbishment Program

Comprehensive refurbishment of engrave heads

344 Billion – that’s a quick calculation* of the number of cells your engrave head has cut over the last 5 years. OHIO GT offers an engrave head refurbishment program to reinvigorate your current head to like new condition and performance.

The refurbishing program actually consists of two important pieces: the head refurb itself and a loaner engrave head. The loaner head allows you to continue your production while the original head is re-conditioned. While you continue cutting cylinders, OHIO’s factory-technicians review your original head and get to work making it as good as new.

The original head is disassembled, cleaned and inspected.

Parts that are tired are replaced with new. Control electronics are also evaluated since they are an integral part in the engrave head performance. The head is then re-assembled and sent to the lab for a full set of tests prior to the actual tuning. When tuning is completed, the head is painted and returned to you with the same warranty as a brand new head.

The pictures tell you the story of an engrave head before and after refurbishment.

This head is a VISION 1, running at 4500 cells/second. It shipped from OHIO in 1997 on an M820 engraver and came back home after 20 years of operation. As you can see, it shows signs of its age: missing parts, lower air nozzles restricted by dust, and a stylus arm that shows significant wear. Once it was cracked open, the interior shows two decades of accumulated dust and corrosion.

Head refurbishment for this unit included:

  •  Complete disassembly
  • A thorough cleaning
  • Media blasted to remove surface corrosion and paint
  • Stylus arm replaced
  • Damping material replaced
  • Shoe assembly rebuilt, including a new drive motor
  • Internal clamps and mounting hardware replaced
  • Stylus position sensor replaced
  • Missing smaller parts replaced
  • New Air Filter added to the lower air nozzles
  • New paint
  • A complete suite of engraving tests
The new filters for the air nozzles were added to the engrave head (right filter is removed).
The stylus arm has been replaced: no groove.

The head required significant work, but when finished, it is ready to tackle the next 344 billion cells – or more!

* Calculated using 0.75m2 engraved area per cylinder, 70 l/cm screen, 2500 cylinders per year for 5 years.
