Felt circles are used for polishing various surfaces (ferrous and non-ferrous metals, stone, glass and any other materials). Semi-coarse felt circles are used for polishing surgical instruments, parts of precision measuring instruments, etc., which require high quality processing. Polishing of non-ferrous metals and aluminum is best done with felt circles made of soft felt. Felt wheels work better at low speeds. Recommended speeds are 5-10 m / s. Excessive speed makes the surface seem harder, and at the same time under the action of increased centrifugal force, the polishing composition breaks off from the felt circle and is wasted. It is recommended to use felt circles together with polishing pastes. Advantages: - The polishing wheel is made of 100 percent of fine wool, fibers are fixed on a strong basis. - Dense pile, evenly distributes polishing paste on a surface, consistently, removing scratches and defects. - The felt polisher is more aggressive, than foam rubber polishing wheels, felt dissipates heat much better therefore working surfaces do not heat up so much. WARNING! Circle with a diameter of 125 mm, seat - 22 mm.
