PFERD/VSM Actirox Abrasive Discs

There are lots of good reasons to choose the PFERD/VSM Actirox Ceramic grain fibre discs, and pretty much all of them end up with you saving time and money.

With an opening sentence like that I’m tempted to leave this review right there because we have cut straight to the heart of the matter. Just kidding – I should share with you some of the technologies and features that allow you to remove maximum stock and require less pressure than regular fibre discs. So read on because these products come out of Hannover in Germany and will have a positive impact on your grinding projects.

For our testing we were supplied with two ceramic grain, Actirox fibre discs: the AF799 is recommended for use on Steel, but can also be used on Stainless Steel (Un Alloyed Steel) and the AF890 is recommended for Stainless Steel, but can also be used on Steel (Super-Alloys and Stainless Steel (INOX). The main difference is that the AF890 includes additional top size, which leads to a cool grinding process and extended service life.

I mentioned technologies earlier and the reason that the PFERD/VSM Actirox discs are performing so well and outperforming their competitors by up to 50 per cent of stock removal seems to directly come from the quality and design of their ceramic grain production. PFERD/VSM is one of only a few manufactures of ceramic grain globally and having their production facility in Hannover has given them a decisive influence on the performance of PFERD/VSM abrasives. PFERD is the exclusive VSM agent in Australia.

The latest generation of abrasives is PFERD/VSM’s geometric-shaped abrasive grain, which produces an aggressive and faster cut, making it ideal for stock removal from alloyed steels and stainless workpieces.

Designed For:

  • Superalloys
  • Stainless steel
  • Aluminium
  • Unalloyed steels
  • Non-ferrous metals

The reason the PFERD/VSM Actirox discs are performing so well across their life span and seriously outlasting competitors’ discs is down to the geometric-shaped ceramic grain breaking down in a defined fashion. It won’t round off and produce dull and less efficient grinding as the disc wears out. The ceramic grains break down consistently producing new, sharp edges, providing efficient grinding results across the entire life span of the disc.

Due to the extremely high stock removal, you will physically get through more workpieces in the same amount of time with less downtime and without having to change discs regularly.

Flat Grinding, Weld Prepara-Tion And Imperfection Removal

Getting up close and personal with the discs you can see that the pyramid-like grain when grinding flat surfaces, the amount of stock removal is impressive.

I have used bonded abrasive discs in the past, but these fibre discs were extremely impressive at grinding surfaces. The tall and visible ceramic grain makes it the perfect choice for deburring, bevelling, preparation of pre-welding surfaces, cleaning, grinding of cast parts removing imperfections, and levelling of weld seams.

Grinding Tests

In our grinding tests I had a selection of flat bar, i-beams, cylindrical pipe and other off cuts to rip into, and that’s exactly what we did. After securing the materials ready for grinding and placing the PFERD/VSM 890 and 799 onto Bosch grinders (using the PFERD H-GT125 high performance backing pad for even further enhanced performance), I started with a very heavy-handed approach. I simply ground into the i-beam with significant force to remove as much material as possible. Using both circular techniques and simply letting the disc grind deep into the steel, after five minutes or so I inspected the disc and was surprised at the condition and substantial amount of ceramic grain left on the disc. From the flat bar to the i-beam and the other material, the results were the same – massive grinding performance, longevity and impressive stock removal.

Perfect For Working On:

  • Slabs
  • Tools
  • Pipes
  • Tanks and containers
  • Hydraulic cylinders
  • Wire
  • Castings and forgings
  • Rollers

The Wrap-Up

There is no doubt in my mind that the PFERD/VSM Actirox range of ceramic fibre discs is a big step forward with the geometric-shaped ceramic grain, which directly leads to maximum stock removal. When compared to conventional ceramic grain abrasives you would be looking at around double the stock removal. The icing on the cake is that you don’t need to use as much pressure as regular grinding fibre discs, which means you will be less fatigued at the end of the day.
