Centrifugal Disc Finishing Tip 5. Too Many Parts In The Machine

 

When your process is first established a full load of parts should be calculated (be it 5,500 or even 5,000). This number of parts will be equivalent to a volume which then be added to the media to fill the machine to the correct level ensuring that all operates as it should.

Centrifugal Disc Finishing Tip 4. Regularly Check Your Seal Gap

 

The seal gap between the moving spinner and stationary tub (bowl) allows the process water, particles and any contaminants to be carried out of the bowl so the process can operate and perform to its optimum capability consistently.

Centrifugal Disc Finishing Tip 3. Check You Have The Right Amount Of Water And Compound In The Machine

 

Water and compound are added into the machine to facilitate the cutting process and remove any debris coming from the media, parts and any additives so the process stays clean, the media can keep cutting and doing its work as it should do and to protect the parts being processed (i.e. with a rust inhibitor if corrosive).

Centrifugal Disc Finishing Tip 2. Check That The Media Condition Is Good

Abrasive media (for deburring, radiusing, blending machining marks, etc…) needs to have an ‘open face’ to work as it should. This is where you can feel the abrasive particles when dragging your finger Medianail over the surface of the media (like a file). When media becomes ‘clogged’ due to insufficient levels of compound being added to the process bowl, poor draining, poor quality media, etc… it becomes smooth (and even shiny in extreme cases). Often times users can think this to be a benefit as ‘it lasts forever’. In truth though it just has stopped cutting and not only does it last forever, so do your process times! If your media is smooth and your finish or process times are adversely affected it is time to throw it away and refill the machine with new media.

Centrifugal Disc Finishing Tip 1. Regularly Check That You Have Enough Media In Your Machine

 

As most media (ceramic and/or plastic) wear, the level in your machine can drop significantly over time. As mass finishing processes work by covering the part with the media and the media moving over the edges to create the deburring, radiusing, etc… it is important a ratio of media : parts is retained.

Wet / Vapour Blasting – What Is It And Why Should You Consider Using It?

Wet or Vapour blasting is a mechanical method of cleaning and preparing a surface. It employs a water/ media mix, a pump together with added pressurised air. The process is widely used for a range of applications from general cleaning through to highly technical and accepted standards for industries including; aerospace, nuclear, the food industry, medical, pharmaceutical, oil and gas, utilities, powertrain, motorsport and automotive. The process is a very economical, versatile and efficient cleaning and finishing process and is used in a wide range of both general and specialised surface preparation work.

Shot Blasting Tip 9 – Check Your Component Starting Condition Is The Same

 

Sometimes things change … including the starting condition of your component parts to be blasted. Worn tooling, changes in materials or investment in new manufacturing methods can result in you no longer getting the result from your shot blasting machine.

Shot Blast Tip 8 – Check Your Blast Wheel Amp Efficiency

 

A number of factors can affect blast wheel operating efficiently, some of which may not be obvious until your shot blast machine is stripped down and/or serviced. Monitoring the amps the blast wheels are pulling can allow you to see that something needs attention.
