Avoid Media Glazing to Prevent Process Inefficiencies, Breakdown

Media plays an essential role within a mass finishing process. Whether ceramic, plastic, or polishing and drying, optimal media mix and conditions must be maintained to produce precise finishing results.

“Glazing” occurs when the surface of the media becomes contaminated with metal fines and other debris from the work pieces. As a result, the media becomes very shiny and frequently looks like a piece of aluminum, brass, steel, zinc, etc.

Because glazed media completely loses its original surface properties, it no longer has any grinding effect. Instead, glazed media creates a sort of uncontrolled burnishing. It also retains dirt and other particles which are then deposited on the work pieces.

The image above depicts (from left) media states include clean, heavily glazed, partially cleaned, and fully cleaned.

Rosler has more than 60 years of media production experience. In that time we’ve seen—and corrected—countless examples of ineffective surface finishing as a result of media glazing.

Mass Finishing Media, Part 3 – Why Discharging Undersized Media, Maintaining Media Levels Are Crucial

Mass finishing processes are effective because the motion of media against work pieces transforms the surface of the work pieces. The deflashing, descaling, edge rounding, polishing/smoothing, cleaning/oil removal/degreasing, and/or grinding effects change the surface of the media itself along with the work pieces.

As a result, media wears down over time, losing its shape, size, and effectiveness. Known as undersized media, this worn media must be discharged and replaced with fresh media to ensure proper processing and safety.

Whether a process uses ceramic, plastic, or polishing and drying media, Rosler stresses the importance of monitoring media levels and the mix of new and worn media for precise and safe mass finishing results.

Mass Finishing Media, Part 2 – Tips for Measuring Media-to-Work Piece Ratio

Maintaining the right ratio of media to work pieces is essential to achieving precise, repeatable results in mass finishing processes where work pieces and media loosely tumble in the processing bowl.

Ensuring that the work pieces are properly embedded in the media allows the media to perform its designated grinding or polishing function as well as cushioning the work pieces from damage caused by part-on-part impingement.

Building upon our last post on the series about navigating the complex media selection considerations, Rosler’s team of experts now discusses tips for determining the best media-to-work piece ratio.

Basic Rule of Thumb

The standard ratio of media to work pieces is around 3-to-1 by volume – meaning that the mix is 3 parts media to 1 part of work pieces – but the exact ratio varies based on the aggressiveness of finishing required as well as the work piece’s material, shape, size, weight, and delicacy or lack thereof.

Mass Finishing Media, Part 1 – Don’t Navigate the Complex Selection Process Alone

The importance of the media selection in any surface finishing process cannot be emphasized enough. These consumables are essential “precision tools” for achieving the specified finishing results.

Selecting the right media is a complex task. That’s why you should consult an expert such as Rosler for guidance.

Even after a mass finishing process has been established, the media status must be constantly monitored and, if necessary, corrected. When different work pieces are processed or finishing tasks are altered, exchanging the currently used media type with another may be required.

Careful and collaborative media selection is crucial to a mass finishing success.

Compounds are Key to Mass Finishing Success

Machinery and media are nothing in the mass finishing world without the right compound.

A manufactured object can be designed to specifications, but if it doesn’t look and feel finished, it may be rejected.  A metal alloy can be structurally perfect, but surface corrosion may make it less presentable. Process water may work well for initial cycles before contaminants wear down its effectiveness over time.

The right compound for a given mass finishing process can solve each of these problems and more.

Range of compounds and media

The quality of consumables used in mass finishing is a key factor in surface processing.  Using consumables with a consistent high quality is crucial to attain set surface specifications, process times, costs and to manage considerations to any environmental impact.

There are in excess of 1700 types of vibratory media consisting of various shapes, sizes and incorporating a percentage of abrasive.  These are divided typically between ceramic and plastic families.

Ceramic Media Production

A ceramic media has a higher density than that of plastic media.  Ceramic chips of various shapes and sizes are formed, fired and held at certain temperatures and durations; providing an infinite range of variation and capability.

A consistent, supreme quality media is extremely important for the user to obtain a uniquely stable and reproducible surface finishing result.

Ceramic media is manufactured to exacting standards, controlled  in a fully-automated way.

Plastic Media Production

The manufacture of the plastic media is also totally automated.

The plastic media is of a lower density than that of the ceramic media, therefore it is suitable for a more gentle treatment of  critical component parts and softer metals.

The process involves mixing, forming and curing of the media and the whole process is computer controlled and continuously monitored.  This quality standard ensures a consistent wear and cutting performance, and repetitive results during the finishing process.

Surface Finishing Compounds

Compounds can be added to the vibratory process, optimising the surface specification for: degreasing, brightening, polishing, corrosion protection and producing surfaces free of stains.

Another important function is keeping the process clean.  The compound continuously flushes tiny metal particulates from the chip media and other contaminants out of the mass finishing system, keeping the media active and the parts free from contamination.

Depending on the specific process, compounds will provide various options of acidity and alkalinity as a pH factor.

Despite compounds being used for many years in mass finishing applications research and development constantly progress new formulations for special applications.

The range of different compounds is broadly diversified:

  • Liquid compounds
  • Recycling compounds
  • Powder compounds
  • Grinding compounds
  • Polishing compounds
  • Dry-polishing compounds
  • Cleaning (degreasing) compounds
