The most common preparation pad for a grinding tool is a felt wheel made of high-quality pressed wool. Such pads can be fine-wool, half-coarse and coarse-wool. It is good to use the densest felt grades as they are the most durable. On the other hand, fine-wool wheels are used to process particularly critical parts of machines and devices. Half-coarse felt wheels are used for polishing surgical instrument, parts of precise measuring instrument, and those details which require high quality finishing. Polishing of non-ferrous metals and aluminium is preferably carried out by the softest preparatory pads.Felt pads are more effective at low circumferential speeds. Excessive speed makes the surface firmer and at the same time the polishing composition breaks off and is wasted under the effect of centrifugal force. All the preparatory pads get dirty easily, so they should be stored away from dust. Visit our webpage to know the whole range of consumables for your electric tools are other equipment.
