8 Considerations When Purchasing a Rotary Vibratory Machine

Buying Mass Finishing equipment, as with all investments, can be a bit overwhelming at first.   There will surely be a number of suppliers and machine types available to you.  In order to ensure you get the best value for your money we recommend you consider the following when purchasing a rotary vibratory machine:

Movement– Appearances can be deceiving, don’t be fooled into thinking all machines are the same just because the look similar.  Always test the machine and its processing ability before you buy!  Test its amplitude, see how regular the movement is, is it consistently driving the same way?

Strength and durability – Check how heavy the machine is, usually you’ll find something costs less because it is made of cheaper and lighter materials.

THE 9 MOST COMMON MISTAKES YOU NEED TO AVOID TO GET THE MOST OUT OF YOUR MASS FINISHING MACHINE

When maintained properly, mass finishing equipment can be very user friendly.

As a result sometimes operators can get into the habit of just turning them on each day and ignoring simple operating and maintenance rules.  Avoiding the following 9 mistakes that operators commonly make will help you get the most from your equipment:

  • They let the media level drop, often with the aim of saving money or so they can get more work pieces in. This changes the ratio of work pieces per media though and can affect process times, unloading ability, can cause components to damage each other, and can result in the required finish not being achievable.

New Vibratory System Design Accommodates Complex Shapes

Vibratory finishing systems are best known for treating large volumes of mass produced parts. However, thanks to a variety of new, innovative equipment designs, they are increasingly utilized for finishing single work pieces with highly complex geometries.

An excellent example of this new equipment design is Rosler’s model R150/2 DL. A rotary vibrator without an inner dome, this unique finishing process allows for work pieces to be bolted to the vibratory processing bowl.

Tips to optimize your surface finishing process – Tip #3

 

Tip #3 – Optimum operating conditions

Once a mass finishing process has been established by the selection of machine, media and compound, the system must be constantly monitored and, of course, properly maintained. The good news is, this is quite easy! By following a few simple quality control rules, the process will remain absolutely stable, producing the desired finishing results for many years:

Tips to optimize your surface finishing process – Tip #2

Tip #2 – The need for processing trials

Of course, the selection of the right machine, media and compound can sometimes be a bit intimidating. Not only does a mass finishing user have to choose among a wide variety of machine types and sizes, they must also pick the right media from hundreds of media types, shapes and sizes. And on top of all this Read more about processing trials

Tips to optimize your surface finishing process- Tip #1

Tip #1 – The work pieces are always at the center

The development of any surface finishing solution always revolves around the work pieces. Their material, size, shape and above all, the finishing objectives, determine what type of finishing process must be selected.

The work piece size is especially important. For example, the deburring and edge

Every Day From Start To Finish

Mass finishing isn’t a term that everyone would necessarily know.  Mention it to most people and you’re likely to be met with a blank stare or a look of bewilderment.  Interestingly though we all come in to contact with the things it does on a daily basis.   So to explain this we thought we’d take you through a day in the life of Rösler mass finishing:

The Reasons Why Super Finishing Enhances Component Performance

Super Finishing removes the asperities that are inherent in the manufacturing process. By safely removing these microscopic peaks, the Super Finishing process leaves a much more uniform surface that reduces friction and allows for increased lubrication capability.  While the dimensional integrity of the part remains intact, the result is an improved component that will operate at lower temperatures, have increased durability, quieter operation and increased time between maintenance.

 Better surface properties on gear teeth and other functional surfaces are responsible for:

  • reducing friction and wear;
  • reducing operating temperature, even at high speeds;
  • eliminating any need for ‘run in’ time and reducing the risk of component failure at the initial stages of its life;
  • reduction of vibration and noise within the unit, again increasing its marketability and improving its performance;
  • cleaner lubricant as a result of reduced component wear producing ‘debris’ to pollute the component’s working environment (resulting again in shortening the component life span);

PureFinish® Stainless Steel Treatment For Optimum Hygiene

PureFinish® is a post-processing technique.  This technique allows stainless steel to be finished to a smoother surface with a low and reproducible SRI value below 0.010.  In practice, this produces a surface with a very low degree of adhesion characteristics. The PureFinish® treatment has been extensively tested by TNO. TNO, a Dutch organisation is the leading institute for Applied Scientific Research.  The SRI value (Soil Retention Index) was investigated because this parameter most accurately describes the relationship between surface structure, contamination and cleanliness.

Within the food and pharmaceutical industries hygiene is a top priority, not only for safety but also to prevent contamination and to ensure the quality of the product in terms of taste, aroma and appearance.  The occurrence of contamination through bacteria, proteins or other elements must therefore be prevented.  Process plants require a defined, homogeneous and reproducible surface for all parts that come in contact with food, beverage and pharmaceutical products.
