Flap discs for stock removal

The average flap disc has the capacity to grind reasonably quickly and provide a reasonable finish. In comparison to the grinding disc, it produces hardly any noise and is free of vibration. It has been developed and continuously improved over many years. In the past, one disc was used to work all types of material and workpieces. Nowadays, however, there are very specific flap discs with very distinct properties. As a result, we now have special discs available to work specific material in very specific circumstances. Given the correct choice, each operator has efficient and technically advanced discs at his disposal to achieve a very controlled finish.
With a good flap disc it is important that the abrasive grit wears at the same rate as the cloth.
Given the very large variety on the market, it is not easy to make the right choice. If requested, the Cibo experts can provide an accurate analysis of your requirements and will advise you on how to save time and money.
The following textblocks contain an overview of the parameters that will determine your choice.
They provide you with guidelines for selecting flap discs for stock removal.

Stock removal capacity

This is often one of the first parameters under consideration in choosing a flap disc. If this parameter is important to you, you should take into account the total stock removal capacity of a disc within a specific time frame and under similar circumstances.
After all, certain discs have a very high initial cutting power, but they lose this cutting capacity after 3 to 5 minutes. Other discs only offer very high stock removal capacity at a high working pressure with the machine at high capacity. This is tiring for the operator; the machines required weigh considerably more, and not everyone has high-powered machines available.

Useful lifespan

Very often, the total lifespan of a disc is used as a reference when making a selection. At first glance, this may appear a good line of thought, However, when we look at the total grinding cost, we often find that this parameter is deceptive. In most industrial countries, labour costs are a very important factor in determining the total finishing costs of a workpiece. Therefore, your total cost price is not only determined by the lifespan, but also by the quantity of stock removal.


Price of the disc

Very often, it is easy to allow oneself to be blinded by the purchase price of the disc. There are very cheap discs available on the market today which at first glance appear excellent. In this context, many operator has personally experienced how deceptive this can prove to be. Please read on and you will find out that the most expensive disc to purchase is usually the cheapest to use.


Total grinding costs

A cost price that takes into account all elements that determine cost is probably the only correct one.
The speed and amount of stock removal per unit of time during the entire life span of the disc are the most decisive factors in the cost price of grinding.

What type of flap disc to select?

Plastic backings do not have any immediate advantage over glass fibre backings. The glass fibre backings used by Cibo are entirely free from iron and consequently are ideal for use with stainless steel. Furthermore, they wear down together with the abrasive cloth without causing any damage to the workpiece. They therefore allow you to completely use the available abrasive cloth.

 Did you know that Cibo has set up its own flap disc department? In mid-2010, production capacity amounted to 2,500,000 discs. For these flap discs, Cibo uses abrasive cloth with specific properties. The standard, Industrial and the High Performance lines with their zirconium oxide grit, as well as the Top line with our latest ceramic quality, ensure the very fast removal of material and allow you to save considerably on labour.
