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

1 Comment

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

2 Comments

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

3 Comments

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.

Mass Finishing Success Requires Constant Operational Focus

Leave a comment

When most companies take on capital expenditure projects such as purchasing mass finishing equipment, very careful attention is paid to investing in the most productive, cost‐efficient equipment as possible to achieve the best possible quality. Operational efficiency is often another story.

Once the equipment is up and running routine takes over and less attention is paid to keeping the equipment operating at its peak performance. Whether the machinery is never calibrated to reach its fullest potential or the on-going process is not carefully monitored once the process is dialed in, lacking operational focus can be costly and counterproductive. Figuratively speaking, poorly managed mass finishing operations are pouring money down the drain!

Rosler works with its clients to ensure that our machinery delivers initial success and continues to provide precise, repeatable results long into the future by promoting operational attention and heading off costly mistakes.

Consequences of Inattention

For mass finishing processes, the lack of operational focus may take many forms individually or simultaneously, including:

Rosler & Lumag – Combining Multiple Solutions in a Single Finishing System

Leave a comment

Finding a solution to our clients’ needs is nothing new for Rosler, nor is combining multiple solutions into a single finishing system. Take our work with Polish brake pad manufacturer Lumag Sp. z o.o. (Lumag), for example.

When they faced the challenge of de-oiling, deburring, and surface roughening brake pad carrier plates as part of their punch press process, they turned to us for a cleaning and mass finishing solution.

The Situation

Upon its founding in 1988 by Marek Zak, Lumag specialized in the production of brake linings. As the company implemented its own brake pad manufacturing technology, their products and offerings evolved. In addition to achieving enormous technological progress and applied engineering solutions, Lumag amassed a collection of machinery in need of constant upgrades and integration.

In order to meet the continuous rise of quality and safety standards for its brake pads for drum and disk brakes for commercial vehicles as well as brake pads for passenger cars and motorcycles under the trade name Breck, Lumag needed a partner with automotive expertise who could combine multiple solutions in a single system.

Innovative Vibratory System Offers Precision Finishing of Delicate Work Pieces

Leave a comment

Innovation is at the heart of engineering. At Rosler Metal Finishing, our engineers are constantly finding a better way to help our customers meet their surface finishing needs. That’s why they developed the R 150 DL-2 rotary vibrator.

In addition to uses in the aerospace, automotive, tool and die making, electrical engineering, and equipment manufacturing industries, the R 150 DL-2 has proven its worth in the medical industry as well. In fact, this machine helped Waldemar Link GmbH & Co KG (LINK®) process its endoprosthetic components.

The R 150 DL-2 was an excellent choice for LINK’s new “bi-mobil” hip implant. The implant offers patients a higher degree of mobility by inserting a movable PE joint in the acetabular cup. The PE-joint in turn is clamped to the ball of the hip stem. To minimize friction and prevent premature wear, the inside of the cup requires an extremely smooth surface, which can only be achieved with a high gloss polished finish—something the R 150 DL-2 easily achieves where other surface finishing companies failed.

The perfectly smooth, polished inside of the acetabular cup minimizes friction adn prevents premature wear.
